PROSPECTUS SUMMARY

THE FOLLOWING SUMMARY IS QUALIFIED IN ITS ENTIRETY BY THE MORE DETAILED
INFORMATION AND THE CONSOLIDATED FINANCIAL STATEMENTS AND NOTES THERETO
APPEARING ELSEWHERE IN THIS PROSPECTUS. EXCEPT AS OTHERWISE NOTED OR UNLESS THE
CONTEXT OTHERWISE REQUIRES, THE INFORMATION CONTAINED IN THIS PROSPECTUS ASSUMES
NO EXERCISE OF THE OVER-ALLOTMENT OPTION GRANTED BY THE COMPANY TO THE
UNDERWRITERS.

THE COMPANY

By utilizing its core collection of proprietary data standardization
methodologies, value-added clinical measurement tools and data bases, including
the International Classification of Clinical Services SystemTM (the "ICCS
SystemTM"), the Company creates clinical information systems and products from
its many large and disparate data streams. The ICCS SystemTM allows for the
standardization and comparison of detailed clinical data across a broad range of
data sources. The Company's proprietary disease management methodologies link
the costs, quality, utilization and outcomes of medical services delivered to
patients in various clinical settings. These methodologies and technical
resources permit the Company to provide a level of clinical information that is
substantially more detailed and useful in modifying clinical practice patterns
than information derived from traditional health care data sources.

As a result of its unique ability to integrate health care data collected
from numerous sources and across varied treatment settings, the Company believes
that it is well positioned to offer the information systems and products
necessary to continue to increase average revenue per customer through the sale
of more sophisticated and comprehensive Decision Support Systems. The Company
continually seeks to enhance its systems and products through internal product
development efforts and acquisitions of other companies, product lines and data
resources, as well as through the creation of strategic relationships with key
health care industry participants. Since 1991 the Company has acquired, as part
of its overall growth strategy, a total of 14 health care information companies,
product lines and data resources. The Company has also entered into an agreement
to acquire LBA Health Care Management, Inc. ("LBA"), a provider of sophisticated
health care information products. See "Business -- Recent Developments."

The Company utilizes a highly specialized direct field sales force to
market Decision Support Systems. The Company's marketing and pricing strategies
are focused on the generation of recurring revenue from Decision Support Systems
through multi-year agreements (typically two to three years) and through the
renewal of its Syndicated Products, which are updated annually. During 1995,
approximately 69% of the Company's revenue was recurring in nature. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Overview."

Unless the context otherwise requires, references in this Prospectus to
"HCIA" and the "Company" refer to HCIA Inc. and its predecessors and
subsidiaries. The Company's executive offices are located at 300 East Lombard
Street, Baltimore, Maryland 21202, and its telephone number is (410) 895-7470.

RECENT ACQUISITIONS

LBA HEALTH CARE. On July 19, 1996, the Company entered into a definitive
agreement to acquire LBA for approximately $130 million, $100 million of which
is payable in cash and $30 million of which is payable through the delivery of
Common Stock. It is anticipated that the acquisition will be consummated on or
about August 9, 1996. LBA is a provider of health care information products that
combine data collection, benchmarking and decision support tools that enable its
customers to achieve significant cost savings by (i) improving quality of
outcomes, (ii) reducing clinical resource consumption and (iii) optimizing labor
utilization. LBA's principal products include its VALUE ENHANCEMENT systems and
Centers of Excellence programs which utilize comparative data base analyses and
a clinical implementation management team to assist customers in reducing
clinical resource consumption and improving outcomes in specific practice areas,
such as orthopaedics and cardiology. LBA's proprietary data bases contain
detailed data from approximately 250 providers and provider groups that are LBA
customers.

RESPONSE HEALTHCARE. In May 1996, the Company acquired Response Healthcare
Information Management, Inc. ("Response") for approximately $6.2 million in
cash. The acquisition of Response provides the Company with expertise and
products in patient-centered data collection and represents a significant
enhancement of the Company's system and product offerings to the managed care
market.

<PAGE>
RISK FACTORS

IN ADDITION TO THE OTHER INFORMATION IN THIS PROSPECTUS, THE FOLLOWING
FACTORS SHOULD BE CONSIDERED CAREFULLY BY PROSPECTIVE INVESTORS.

ACQUISITIONS. The Company has, in part, expanded its systems and products
through the acquisition of health care information companies, product lines and
data resources, including the Company's recent acquisition of Response and the
Company's pending acquisition of LBA. The Company intends to continue the
acquisition of methodological, analytical and technical resources that will
further enhance and expand the Company's systems and products. Except for the
pending acquisition of LBA, the Company currently has no agreements, commitments
or understandings with respect to any such acquisitions.

Acquisitions involve numerous risks, including difficulties in the
assimilation of operations and products, the ability to manage geographically
remote units, the diversion of management's attention from other business
concerns, the risks of entering markets in which the Company has limited or no
direct expertise and the potential loss of key employees of the acquired
companies. In addition, acquisitions may involve the expenditure of significant
funds and the incurrence of significant charges associated with the amortization
of goodwill or other intangible assets, write-offs of acquired in-process
research and development costs and/or future write-downs of the recorded values
of assets acquired. There can be no assurance that any acquisition will result
in long-term benefits to the Company or that management will be able to manage
effectively the resulting business. See "Business -- Business Strategy."

In connection with the LBA acquisition, the Company expects to incur a
one-time charge in the third quarter of 1996 of approximately $41.2 million
related to acquired in-process research and development costs. The Company also
will record significant goodwill and other intangible assets associated with the
LBA acquisition, which the Company intends to amortize over periods of six to
twenty years. In addition, the LBA acquisition will result in a significant
expansion of the Company's system and product offerings, and the integration of
LBA with the Company will require significant management time and resources.
There can be no assurance that the Company will be able to integrate LBA systems
with the Company's existing systems and products or achieve the operating
synergies necessary to make the acquisition successful.

MANAGEMENT OF GROWTH. The Company is currently experiencing a period of
rapid growth and expansion which could place a significant strain on the
Company's personnel and resources. The Company's growth has resulted in an
increase in the level of responsibility for both existing and new management
personnel. Many of the Company's management personnel have had limited or no
experience in managing companies as large as the Company. The Company has sought
to manage its current and anticipated growth through the recruitment of
additional management and technical personnel and the implementation of internal
systems and controls. However, the failure to manage growth effectively could
adversely affect the Company's operating results. See "Business -- Business
Strategy" and "Management."

DEPENDENCE ON KEY PERSONNEL. The Company depends to a significant extent
on key management, technical and marketing personnel. The Company's growth and
future success will depend in large part on its ability to attract, motivate and
retain highly qualified personnel, including management personnel of acquired
companies. Except for an agreement with George D. Pillari, its Chairman of the
Board, President and Chief Executive Officer, the Company does not have
employment agreements with any of its officers. The loss of key personnel or the
inability to hire or retain qualified personnel could have a material adverse
effect on the Company. See "Management."

SHORT HISTORY OF PROFITABILITY; VARIATIONS IN QUARTERLY RESULTS. After
achieving profitability during 1993 and 1994, the Company recorded a net loss
for 1995 as a result of the one-time charge incurred during the period related
to acquired in-process research and development costs in connection with the
CHAMP acquisition. The Company has reported net income of approximately $964,000
for the six months ended June 30, 1996. However, there can be no assurance that
revenue growth or profitable operations can be sustained in the future. The
Company has experienced and expects to continue to experience variations in
quarterly results. Recent quarterly variations are primarily due to the effect
of one-time charges related to acquired in-process research and development
costs. Quarterly results are also influenced by the timing of release of certain
systems and products as a result of

<PAGE>
the annual release of certain external data sources. The Company's operating
results for any particular quarterly or annual period may not be indicative of
results for future periods. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations -- Quarterly Results of
Operations."

DEPENDENCE ON INTELLECTUAL PROPERTY RIGHTS. The Company has made
significant investments in the development and maintenance of its core
collection of proprietary data standardization methodologies, value-added
clinical measurement tools and technical resources that are used to transform
its many large and disparate data streams into clinically relevant information
products. See "Business -- Systems and Products." The Company relies largely on
its license agreements with customers and its own security systems,
confidentiality procedures and employee nondisclosure agreements to maintain the
trade secrecy of its proprietary information. There can be no assurance that the
legal protections and precautions taken by the Company will be adequate to
prevent misappropriation of the Company's proprietary information. In addition,
these protections do not prevent independent third-party development of
functionally equivalent or superior systems, products or methodologies. See
"Business -- Intellectual Property."

COMPETITION. The health care information market is intensely competitive
and rapidly changing. The Company competes for the sale of systems and products
and the resulting access to data with different companies in each of its target
markets. Competitors vary in size and in the scope and breadth of the products
and services offered. Many of the Company's competitors have significantly
greater financial, technical, product development and marketing resources than
the Company. There can be no assurance that future competition, or any
significant loss of access to data resulting therefrom, will not have a material
adverse effect on the Company. See "Business -- Competition."

MAJOR CUSTOMERS. In 1994, one customer, Amgen Inc., accounted for
approximately 12% of the Company's revenue. In 1995, no customer accounted for
10% or more of the Company's revenue. During 1994 and 1995, the Company's ten
largest customers accounted for approximately 29% and 36%, respectively, of the
Company's revenue. Many of the Company's contractual arrangements with its
customers are subject to annual renewal. The loss of one or more of the
Company's largest customers could have a material adverse effect on the Company.
See "Business -- Customers."

INTEGRITY AND RELIABILITY OF DATA. The Company's success depends
significantly on the integrity of its data. Although the Company tests data for
completeness and consistency, it does not conduct independent audits of the
information provided by its customers. Moreover, while the Company believes that
the benchmarking and other clinical, cost and performance information contained
in its data base is representative of the operational aspects of various types
of health care industry participants, there can be no assurance that such
information is appropriate for comparative analysis in all cases or that the
data bases accurately reflect general or specific trends in the health care
market. If the information contained in the data were found, or were perceived,
to be inaccurate, or if such information were generally perceived to be
unreliable, the Company's business and operating results could be materially and
adversely affected.

POTENTIAL COST OF PERFORMANCE GUARANTEES. As part of its VALUE ENHANCEMENT
systems, LBA has guaranteed that each customer will achieve a cost savings
identified as at least equal to the fees the customer pays for the system. To
the extent such cost savings are not achieved, LBA may be subject to claims
related to such guarantees. Although LBA has never incurred a claim under its
guarantee, there can be no assurance that this will continue to be the case.
Liabilities related to such claims could have a material adverse effect on the
Company's business and operating results could be materially and adversely
affected.

VOLATILITY OF STOCK PRICE. The stock market historically has experienced
volatility which has affected the market price of securities of many companies
and which has sometimes been unrelated to the operating performance of such
companies. The trading price of the Common Stock may be subject to significant
fluctuations in response to variations in quarterly results of operations,
announcements of acquisitions, new systems or products by the Company or its
competitors, governmental regulatory action, other developments or disputes with
respect to proprietary rights, general trends in the industry and overall market
conditions, and other factors.

<PAGE>
CHANGES IN THE HEALTH CARE INDUSTRY. The health care industry is subject
to changing political, economic and regulatory influences that may affect the
procurement practices and operation of health care industry participants. During
the past several years, the U.S. health care industry has been subject to an
increase in governmental regulation of, among other things, reimbursement rates
and certain capital expenditures. Various programs have been proposed to reform
the U.S. health care system. Many of these programs contain proposals to
increase governmental involvement in health care, lower reimbursement rates and
otherwise change the operating environment for the Company's customers. Health
care industry participants may react to these proposals and the uncertainty
surrounding such proposals by curtailing or deferring investments, including
those for the Company's systems and products. The Company cannot predict what
impact, if any, such factors might have on its business, financial condition and
results of operations. In addition, many health care providers are consolidating
to create larger health care delivery enterprises with greater regional market
power. As a result, the remaining enterprises could have greater bargaining
power, which may lead to price erosion of the Company's systems and products.
See "Business -- Industry Background."

GOVERNMENT REGULATION. The U.S. Food and Drug Administration (the "FDA")
has promulgated a draft policy addressing the regulation of certain computer
products as medical devices under the Federal Food, Drug, and Cosmetic Act. The
FDA could determine in the future that certain applications of the Company's
systems and products are clinical decision tools subject to FDA regulation as
medical devices. In addition, the Company could become subject to future
regulation of the manufacture and marketing of medical devices and health care
software systems, or to legislation or regulation regarding the use of patient
records or of access to health care data. Compliance with such legislation and
regulation could be burdensome, time consuming and expensive. The Company cannot
predict the effect of possible future legislation and regulation. See
"Business -- Government Regulation."

On July 19, 1996, there were 31 holders of record of the Company's Common
Stock. The number of record holders is not representative of the number of
beneficial holders since many shares are held by depositories, brokers or other
nominees. On July 19, 1996, the last reported sale price of the Company's Common
Stock on NASDAQ was $66 3/8 per share.

DIVIDEND POLICY

The Company has never paid any cash dividends on the Common Stock and does
not anticipate paying any cash dividends on the Common Stock in the foreseeable
future. The Company currently intends to retain any future earnings to fund the
development and growth of its business.

<PAGE>
USE OF PROCEEDS

The net proceeds to the Company from the sale of the Common Stock offered
by it hereby at an assumed price of $66 3/8 per share (the last reported sale
price of the Company's Common Stock on July 19, 1996) are estimated to be $126.3
million ($147.4 million if the Underwriters' over-allotment option is exercised
in full), after deducting the estimated underwriting discounts and offering
expenses payable by the Company. The Company will not receive any proceeds from
the sale of Common Stock by the Selling Stockholders.

The Company intends to use the net proceeds to (i) repay amounts to be
borrowed under a credit facility with First Union National Bank of North
Carolina ("First Union") in connection with the acquisition of LBA, estimated to
be approximately $90 million, and (ii) for general corporate purposes, including
future acquisitions and funding the increased working capital requirements of
the Company as a result of its growth. Any proceeds not utilized to repay
indebtedness or for the other above-described purposes will be invested in
short-term, interest-bearing securities.

Borrowings under the credit facility will bear interest at varying rates
based on an index tied to First Union's prime rate or LIBOR. As of the date of
this Prospectus, the applicable interest rate would have been 8.75%. Upon
application of the net proceeds to the Company of the Offering to repay the
borrowings outstanding under the credit facility, the Company will maintain a
$50 million revolving line of credit for general corporate purposes, including
future acquisitions and working capital requirements. See "Management's
Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources."

CAPITALIZATION

The following table sets forth the capitalization of the Company (i) as of
March 31, 1996, (ii) on a pro forma basis to give effect to the Response and LBA
acquisitions, and (iii) as further adjusted to reflect the sale by the Company

MANAGEMENT'S DISCUSSION AND ANALYSIS
OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

OVERVIEW

HCIA is a health care information content company that develops and markets
Decision Support Systems and Syndicated Products. In 1991, HCIA began a series
of acquisitions of health care information companies, product lines and data
resources. These acquisitions established the Company's ability to provide
systems and products which rely on the integration of detailed clinical and
financial data. Effective as of January 1, 1994, the Company divested certain of
its software product lines, which had generated revenue of approximately $3.0
million during 1993. During 1995, the Company completed several additional
acquisitions of health care information companies, including Datis and the CHAMP
unit of Mercer. In connection with the CHAMP acquisition, the Company recorded a
one-time charge related to acquired in-process research and development costs of
approximately $12.2 million. As a result of this charge, the Company recorded a
net loss for the year ended December 31, 1995. In May 1996, the Company acquired
Response for approximately $6.2 million in cash. In connection with the Response
acquisition, the Company recorded a one-time charge during the three months
ended June 30, 1996 of approximately $4.4 million related to acquired in-process
research and development costs. On July 19, 1996, the Company executed a
definitive agreement to acquire LBA. In connection with the LBA acquisition, the
Company expects to incur a one-time charge during the three months ended
September 30, 1996 of approximately $41.2 million related to acquired in-process
research and development costs. The Company's results of operations include the
results of the acquired or divested entities or product lines since the date of
acquisition or prior to the date of divestiture, as applicable. See Note 1 of
the Notes to Consolidated Financial Statements.

The Company has made a substantial investment in the acquisition and
development of its core collection of methodologies, clinical measurement tools
and technical resources. The Company's strategy is to leverage these resources
across substantially all of its systems and products, thereby giving it the
ability to increase revenue generated from these resources without a
commensurate increase in expenses. In addition to its internal product
development efforts, the Company seeks to continue the acquisition of other
health care information companies, product lines and data resources, and intends
to integrate and leverage these assets into product-line extensions across its
markets. The Company does not track profitability by product line since many of
the Company's resources are utilized throughout its systems and products.

The Company's internal product development efforts are generally in
connection with customer contracts, and the related costs are included as a
component of operating expenses in the year incurred. The Company capitalizes
costs related to internal product development which is not in connection with a
specific customer contract from the point of technological feasibility to the
point of general availability. With respect to acquired companies, product lines
and data resources, the Company has historically completed the acquisitions
using available cash or a deferred payment plan, with recent acquisitions being
funded by the proceeds of the Company's public offerings. The cash portion of
the LBA acquisition will be financed with a credit facility which will be repaid
with a portion of the proceeds to the Company from the Offering. The Company
will also issue a total of 492,960 shares of Common Stock to the stockholders of
the parent company of LBA. See " -- Liquidity and Capital Resources."

As a result of its acquisition of health care information companies,
product lines and data resources, the Company has acquired intangible assets,
the cost of which it amortizes over various useful lives. In addition, the
Company has capitalized internal development costs and acquired assets relating
to the development of methodologies, clinical measurement tools and technical
resources, including its data base, of $3.3 million, $3.4 million, $6.9 million
and $2.4 million during 1993, 1994, 1995 and the three months ended March 31,
1996, respectively. Consequently, the Company has recorded amortization expense
of $3.9 million, $3.9 million, $5.2 million and $1.8 million during 1993, 1994,
1995 and the three months ended March 31, 1996, respectively. See Notes 2 and 4
of the Notes to Consolidated Financial Statements. On a pro forma basis,
assuming the completion of the Response and LBA acquisitions at the beginning of
the respective periods, the Company would have recorded additional amortization
expense of $5.1 million and $1.3 million during 1995 and the three months ended
March 31, 1996, respectively.

<PAGE>
As a result of its unique ability to integrate health care data collected
from numerous sources and across varied treatment settings, the Company believes
that it is well positioned to offer the information systems and products
necessary to continue to increase average revenue per customer through the sale
of more sophisticated and comprehensive Decision Support Systems. With respect
to Syndicated Products and entry-level Decision Support Systems, pricing is
relatively fixed and is influenced by competitive systems and products. With
respect to high-end Decision Support Systems, pricing is often negotiated with
the customer and is based on a number of factors, including the value attributed
by the customer to the System.

The Company's revenue is comprised of both recurring revenue from the
Company's installed customer base as well as from first time sales. The Company
seeks to generate recurring revenue from Decision Support Systems through
multi-year agreements (typically two to three years) and through renewals of its
Syndicated Products, which are updated annually. The Company defines its
recurring revenue percentage as revenue recognized during the period from a sale
of a system or product to a customer who purchased a similar system or product
in the prior period, divided by the Company's total revenue in the prior period.
In determining its recurring revenue percentage, the Company includes in its
revenue the revenue of entities acquired during the period as if such
acquisitions had occurred at the beginning of the prior period. The Company does
not classify revenue as recurring to the extent that it exceeds the revenue from
a similar system or product purchase in the prior period. The Company's
recurring revenue percentages for 1994 and 1995 were approximately 64% and 69%,
respectively.

</TABLE>

THREE MONTHS ENDED MARCH 31, 1996 COMPARED TO 1995

REVENUE. Revenue for the three months ended March 31, 1996 was $14.2
million, an increase of $5.5 million or 63% over the three months ended March
31, 1995. The increase was primarily the result of a 77% increase in revenue
from the sale of Decision Support Systems. Revenue from the sale of Decision
Support Systems represented 83% of the revenue for the three months ended March
31, 1996 and Syndicated Products represented the remaining 17% of revenue.

<PAGE>
The increase in Decision Support Systems revenue was primarily the result
of the Company's continued success in expanding its customer relationships in
the provider and supplier markets, and as a result of the acquisitions of Datis
and CHAMP, both of which occurred after March 31, 1995.

SALARIES, WAGES AND BENEFITS. Salaries, wages and benefits decreased to 47%
of revenue for the three months ended March 31, 1996 from 52% for the three
months ended March 31, 1995. This decrease was a result of the continued
leveraging of the Company's historical investments in technology and basic
infrastructure as revenue increased.

OTHER OPERATING EXPENSES. Other operating expenses, which include
occupancy, travel, and marketing expenses, decreased to 23% of revenue for the
three months ended March 31, 1996 from 28% for the three months ended March 31,
1995. This decrease was a result of certain of these expenses growing at a
slower rate than revenue.

DEPRECIATION AND AMORTIZATION. Depreciation and amortization increased to
16% of revenue for the three months ended March 31, 1996 from 15% for the three
months ended March 31, 1995. This increase was a result of the additional
amortization associated with the acquisitions of Datis and CHAMP as well as
depreciation of other acquired assets.

INTEREST INCOME AND EXPENSE. Net interest income was $199,000 for the three
months ended March 31, 1996 compared with net interest income of $151,000 for
the three months ended March 31, 1995. This increase was the result of a higher
invested balance in 1996.

INCOME TAXES. The Company's effective tax rate was 39.4% for the three
months ended March 31, 1996 compared with 40.5% for the three months ended March
31, 1995. The decrease was the result of a portion of the Company's investments
being placed in tax-exempt securities, as well as the tax benefit associated
with the exercise of certain non-qualified stock options. This decrease was
partially offset by an increase in non-deductible goodwill.

1995 COMPARED TO 1994

REVENUE. Revenue for 1995 was $48.0 million, an increase of $17.3 million
or 56% over 1994. The increase was primarily the result of a 77% increase in
revenue from the sale of Decision Support Systems. Revenue from the sale of
Decision Support Systems represented 80% of revenue for 1995 and Syndicated
Products represented the remaining 20% of revenue.

The Decision Support Systems revenue increase was primarily the result of
increased sales of Decision Support Systems to providers, particularly as a
result of the acquisition of Datis during the year, and to a lesser extent, due
to increased sales through CHKS, the Company's English subsidiary. Sales of the
Company's Systems to the buyer and supplier markets also increased. In
particular, the Company met several performance milestones pursuant to its
contract with CIGNA Healthcare during the year.

SALARIES, WAGES AND BENEFITS. Salaries, wages and benefits decreased to
46% of revenue for 1995 from 50% for 1994. This decrease was a result of the
leveraging of the Company's historical investments in technology and basic
infrastructure as revenue increased.

OTHER OPERATING EXPENSES. Other operating expenses, which include
occupancy, travel and marketing expenses, decreased to 25% of revenue for 1995
from 28% for 1994. This decrease was a result of certain of these expenses
growing at a slower rate than revenue.

DEPRECIATION AND AMORTIZATION. Depreciation and amortization decreased to
14% of revenue for 1995 from 16% of revenue for 1994. The decrease was the
result of the fixed nature of a large component of the depreciation and
amortization, which is the result of prior acquisitions, being measured against
a larger revenue base.

WRITE-OFF OF ACQUIRED IN-PROCESS RESEARCH AND DEVELOPMENT COSTS. In
connection with the acquisition of CHAMP, the Company acquired CHAMP's ongoing
research and development activities. At the time of the acquisition, the Company
recorded a one-time charge resulting from the write-off of the acquired
in-process research and development costs. This charge totaled approximately
$12.2 million or 25% of the Company's

<PAGE>
revenue for 1995. These costs related to the development of a client server
based system to process and deliver health care data and analysis tools to CHAMP
customers. The amount of the one-time charge was equal to the estimated current
fair value, based on the risk adjusted cash flows (at a discount rate of 20%,
which included cost of capital of 18% and an incremental risk premium of 2%), of
specifically identified technologies for which technological feasibility had not
yet been established pursuant to Statement of Financial Accounting Standards No.
86, "Accounting for the Costs of Computer Software to be Sold, Leased or
Otherwise Marketed," and for which future alternative uses did not exist.

INTEREST INCOME AND EXPENSE. Net interest income was $1.1 million or 2% of
revenue for 1995 compared with net interest expense of $20,000 for 1994. The
increase in net interest income was the result of a portion of the proceeds of
the Company's public offerings being utilized to repay the amount due under the
Company's credit agreement with the Company's former majority stockholder, AMBAC
Inc. ("AMBAC") (approximately $1.9 million), with the balance being invested in
cash equivalents and short-term investments.

INCOME TAXES. The Company's effective income tax rate was (39)% for 1995
compared with 43% for 1994. The change was a result of the Company recording a
net loss in 1995.

1994 COMPARED TO 1993

REVENUE. Revenue for 1994 was $30.7 million, an increase of $2.6 million
or 9% over 1993. Effective January 1, 1994, the Company divested certain of its
software product lines which generated revenue of approximately $3.0 million
during 1993. After eliminating the revenue from these product lines, revenue for
1994 increased by $5.6 million or 22% over 1993. Revenue increased in both of
the Company's product classifications. The increase in Decision Support Systems
revenue was primarily due to increased sales of high-end Decision Support
Systems, offset by a decrease in sales of certain entry-level Decision Support
Systems which the Company is no longer actively marketing. Syndicated Product
revenue increased primarily as a result of the increased penetration of existing
products and the introduction of new products, including THE OUTPATIENT
UTILIZATION PROFILE and THE DIRECTORY OF HEALTH CARE PROFESSIONALS.

SALARIES, WAGES AND BENEFITS. Salaries, wages and benefits decreased to
50% of revenue for 1994 from 51% for 1993. This decrease was a result of the
leveraging of the Company's historical investments in technology and basic
infrastructure as revenue increased. However, during 1994, the Company continued
to increase its investment in sales and marketing personnel at a rate in excess
of revenue growth in order to expand the market penetration of existing systems
and products and to allow for the introduction of new systems and products.

OTHER OPERATING EXPENSES. Other operating expenses, which include
occupancy, travel and marketing expenses, were 28% of revenue for 1994 and 1993.
Decreases in outside data processing and travel costs were offset by slightly
higher marketing and occupancy costs.

PROVISION FOR DOUBTFUL ACCOUNTS. The provision for doubtful accounts
decreased to less than 1% of revenue for 1994 from 2% for 1993. This decrease
was a result of enhanced credit and collection processes and additional
personnel resulting in reduced bad debt losses.

DEPRECIATION AND AMORTIZATION. Depreciation and amortization was 16% of
revenue for 1994 and 1993. The depreciation and amortization is primarily
related to the Company's acquisitions and certain capitalized costs related to
the development of methodologies, clinical measurement tools and technical
resources.

INCOME TAXES. During 1994 and 1993, the Company's effective tax rates were
43% and 51%, respectively. These rates were in excess of statutory rates
primarily as a result of the non-deductibility of the amortization of certain
goodwill. The reduction in the effective rate was primarily due to the increased
earnings of the Company resulting in a reduced impact of the amortization of
certain goodwill.

The Company has experienced quarterly fluctuations in operating results,
which it expects to continue for the foreseeable future. During the three months
ended December 31, 1995, the Company recorded a one-time charge related to
acquired in-process research and development costs in connection with the CHAMP
acquisition. In addition, during the three months ended June 30, 1996, the
Company recorded a $4.4 million one-time charge related to acquired in-process
research and development costs in connection with the Response acquisition.
Similarly, the Company expects to incur a $41.2 million charge in connection
with the LBA acquisition during the three months ended September 30, 1996.
Quarterly results are also influenced by the annual availability of certain data
sources, which affects the timing of the release of certain Syndicated Products
and entry-level Decision Support Systems. As a result, the Company generally
recognizes greater revenue from sale of these systems and products during the
second and third quarters of each year.

<PAGE>
LIQUIDITY AND CAPITAL RESOURCES

In February 1995, the Company completed an initial public offering of
2,012,500 shares of Common Stock at an initial public offering price of $14.00
per share. The net proceeds to the Company from the offering were approximately
$25.7 million. The Company utilized approximately $1.9 million of the proceeds
to repay amounts due to AMBAC under a line of credit agreement. During August
1995, the Company completed an additional offering of 1.5 million shares of
Common Stock at a price of $28.50 per share. The net proceeds to the Company
were approximately $40.3 million. In May 1996, the Company issued 261,951 shares
at a price of $51.00 per share pursuant to the exercise of an over-allotment
option granted by the Company to the underwriters in connection with the sale of
all of the shares of Common Stock owned by AMBAC and its wholly owned
subsidiary, AMBAC Indemnity Corporation ("AIC"). The net proceeds to the Company
from the exercise of the over-allotment option were approximately $12.8 million.

On July 19, 1996, the Company obtained a commitment from First Union for a
credit facility totalling $100 million, consisting of a $50 million term loan
and a $50 million revolving line of credit. Borrowings will bear interest at
varying rates based on an index tied to First Union's prime rate or LIBOR. The
credit facility will be subject to a one-time facility fee of $500,000. The
Company will also pay a commitment fee on the average daily unused portion of
the facility at a rate ranging from 0.25% to 0.375% per annum, depending on the
Company's debt/cash flow ratio. The Company will draw down the entire $50
million term loan and approximately $40 million of the revolving line of credit
in connection with the LBA acquisition and will repay these borrowings with a
portion of the net proceeds to the Company of the Offering. The Company will
then maintain a $50 million revolving line of credit for general corporate
purposes, including future acquisitions and working capital requirements.
Borrowings will be collateralized by substantially all of the Company's assets.
The credit facility will also contain financial covenants applicable to HCIA,
including a debt/cash flow ratio and ratios of debt to capital. The Company
expects to be in compliance with these covenants after drawing on the credit
facility and expects to continue to be in compliance thereafter.

During 1993, 1994, 1995 and the three months ended March 31, 1996, the
Company generated net cash from operations of approximately $2.4 million, $4.4
million, $3.1 million and $3.7 million, respectively. During 1995, approximately
$7.3 million and $1.7 million of cash generated from operations was used to fund
the increase in accounts receivable and the decrease in deferred revenue,
respectively. The increase in accounts receivable was primarily the result of
revenue growth, as well as the timing of receipt of payments from certain major
customers. The decrease in deferred revenue was the result of the timing of
delivery of products to Datis customers subsequent to the acquisition of Datis
by the Company, as well as a decrease in the revenue from product lines
generating a significant portion of the historical deferred revenue balance. Net
cash provided by financing activities during 1993, 1994 and 1995 was
approximately $3.7 million, $568,000, $66.2 million, respectively, primarily as
a result of borrowings under the line of credit from AMBAC, the issuance of
preferred stock to AMBAC and AIC (subsequently exchanged for shares of Common
Stock) and the Company's public offerings in February and August 1995. The net
cash provided by operations and financing activities has been utilized primarily
for capital expenditures and acquisitions. Net cash used by financing activities
during the three months ended March 31, 1996 was $520,000, primarily as a result
of the repayment of certain indebtedness related to acquisitions.

The Company made capital expenditures (including capitalized leases)
totaling $2.0 million, $1.6 million, $3.1 million and $0.9 million during 1993,
1994, 1995 and the three months ended March 31, 1996, respectively. As of March
31, 1996, the Company had net working capital of $35.0 million, including cash,
cash equivalents and short-term investments in the amount of $24.9 million, and
did not have any material commitments for capital expenditures.

In March 1995, the Company completed the acquisition of substantially all
of the assets of John Froehlich Associates for the payment of approximately
$520,000 in cash and the issuance of a note payable in the amount of $480,000,
which was paid in full in February 1996. In April 1995, the Company acquired
certain assets from MetriCor Inc. for a payment of $485,000 in cash and the
assumption of certain liabilities. Also in April 1995, the Company completed the
acquisition of all of the outstanding capital stock of Datis. The purchase price
for the capital stock of Datis was approximately $14.6 million in cash, which
included approximately $14.25 million

<PAGE>
funded by the Company and $386,000 funded with the proceeds received from the
exercise of certain options to purchase Datis stock. In addition, the Company
repaid approximately $900,000 of outstanding debt of Datis. In December 1995,
the Company acquired the CHAMP unit of Mercer for $17.5 million in cash and, in
May 1996, the Company completed the acquisition of Response for approximately
$6.2 million in cash. Each of these acquisitions has been accounted for using
the purchase method of accounting and, accordingly, the assets have been valued
at their estimated fair market value. Funding for the acquisitions was provided
by the proceeds of the Company's public offerings and cash generated by
operations.

The Company expects to incur additional costs of $7 to $10 million to
complete the development efforts related to systems and products obtained in
connection with the acquisitions of CHAMP and Response and the pending
acquisition of LBA, and to integrate these products with the Company's other
products. Such costs are expected to consist of direct labor and contracted
labor costs and are expected to be incurred over the next two to three years.

RECENTLY ISSUED ACCOUNTING STANDARDS

In October 1995, Statement of Financial Accounting Standards No. 123,
"Accounting for Stock-based Compensation" ("SFAS No. 123"), was issued. This
statement requires the fair value of stock options and other stock-based
compensation issued to employees to either be included as compensation expense
in the income statement, or the pro forma effect on net income and earnings per
share of such compensation expense to be disclosed in the footnotes to the
Company's consolidated financial statements commencing with the Company's 1996
fiscal year. The Company expects to adopt SFAS No. 123 on a disclosure basis
only. As such, implementation of SFAS No. 123 is not expected to impact the
Company's consolidated financial statements.

In March 1995, Statement of Financial Accounting Standards No. 121,
"Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to
be Disposed Of " ("SFAS No. 121"), was issued. This statement establishes
accounting standards for the impairment of long-lived assets, certain
identifiable intangibles, and goodwill related to those assets to be held and
used for long-lived assets and certain identifiable intangibles which are to be
disposed. Implementation of SFAS No. 121 is not expected to have a material
impact on the Company's consolidated financial statements.

BUSINESS

GENERAL

HCIA is a leading health care information content company that develops and
markets integrated clinical information systems and products. The Company's
systems and products range from standardized data bases to highly focused
Decision Support Systems that assist its customers in evaluating the efficacy
and economics of health care delivery. HCIA currently sells its Decision Support
Systems to more than 325 customers, including hospitals, integrated delivery
systems, self-insured employers, pharmaceutical companies and managed care
organizations. The Company's Syndicated Products are sold to over 7,000
customers. As a result of its unique ability to integrate health care data
collected from numerous sources and across varied treatment settings, the
Company believes that it is well positioned to offer the information systems and
products necessary to continue to increase average revenue per customer through
the sale of more sophisticated and comprehensive Decision Support Systems. The
Company's marketing and pricing strategies are focused on the generation of
recurring revenue from Decision Support Systems through multi-year agreements
(typically two to three years) and through the renewal of its Syndicated
Products, which are updated annually. During 1995, approximately 69% of the
Company's revenue was recurring in nature. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations -- Overview."

By utilizing its core collection of proprietary data standardization
methodologies, value-added clinical measurement tools and data bases, including
the ICCS SystemTM, HCIA creates clinical information systems and products from
its many large and disparate data streams. The ICCS SystemTM allows for the
standardization and comparison of detailed clinical data across a broad range of
data sources. The Company's proprietary disease management methodologies link
the costs, quality, utilization and outcomes of medical services delivered to
patients in various clinical settings. These methodologies and technical
resources permit the Company to provide a level of clinical information which is
substantially more detailed and useful in modifying clinical practice patterns
than information derived from traditional health care data sources.

RECENT ACQUISITIONS

LBA HEALTH CARE. On July 19, 1996, the Company executed a definitive
agreement to acquire LBA for $130 million. LBA, which had revenue during the
year ended December 31, 1995 and the three months ended March 31, 1996 of
approximately $16.6 million and $7.5 million, respectively, is a provider of
health care information products and services that combine data collection,
benchmarking and decision support tools to identify and quantify cost reduction
and quality improvement opportunities in clinical settings. LBA's principal
products, including its VALUE ENHANCEMENT systems and Health Care Financing
Administration ("HCFA") Centers of Excellence program, utilize comparative data
base analyses and a clinical implementation management team to assist customers
in reducing clinical resource consumption and improving outcomes in specific
practice areas, such as orthopaedics and cardiology. LBA's proprietary data
bases contain detailed data on cost, quality, clinicial resource consumption and
labor/productivity obtained from approximately 250 providers and provider groups
that are LBA customers. The level of information contained in LBA's data bases
is similar to HCIA's ICCS-level data base. HCIA plans to utilize its ICCS
SystemTM to standardize the LBA data bases and integrate them with the
ICCS-level data base.

LBA's systems enable its customers to achieve significant cost savings by
(i) improving quality of outcomes, (ii) reducing clinical resource consumption
and (iii) optimizing labor utilization. The Company believes that LBA's clinical
implementation methodologies will significantly enhance its ability to deliver
clinical solutions that identify and quantify cost reduction and quality
improvement opportunities. Typical LBA customers spend approximately $75,000 to
$100,000 per year on VALUE ENHANCEMENT systems, and approximately 75% of LBA's
customers have purchased at least two systems. As part of a VALUE ENHANCEMENT
system, LBA guarantees that each customer will achieve a cost savings at least
equal to the fees paid to LBA.

Pursuant to the acquisition agreement, the Company will acquire all of the
capital stock of LBA's parent company, HealthVISION, Inc. ("HealthVISION").
Prior to the acquisition, all of the assets and liabilities of HealthVISION not
associated with LBA will be distributed to certain current stockholders of
HealthVISION. The

<PAGE>
purchase price for the acquisition is approximately $130 million (which includes
the payment of certain liabilities, including bank debt and management bonuses),
$100 million of which is payable in cash and $30 million of which is payable
through the delivery of 492,960 shares of Common Stock of HCIA. The Company has
obtained a commitment from First Union for a $100 million credit facility to
fund the cash portion of the purchase price, which the Company intends to repay
with a portion of the net proceeds to the Company of the Offering. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources." Pursuant to the acquisition
agreement, the Company has agreed to file and maintain under the Securities Act
a shelf registration statement for the benefit of certain current stockholders
of HealthVISION. It is anticipated that the acquisition will be consummated on
or about August 9, 1996, subject to compliance with customary closing
conditions.

RESPONSE HEALTHCARE. In May 1996, the Company acquired all of the
outstanding capital stock of Response for approximately $6.2 million in cash.
Response, which had revenue of approximately $2.6 million for the year ended
December 31, 1995, specializes in capturing and analyzing point-of-care,
patient-centered data relating to disease-specific outcomes measurement,
member/patient satisfaction and functional status, as well as the development of
Internet applications. Response's primary customers include managed care
organizations and pharmaceutical companies.

INDUSTRY BACKGROUND

Market driven efforts to contain rising health care costs have resulted in
an increasing demand for access to sophisticated heath care information. During
the five years ended in 1995, the average annual increase in U.S. health care
expenditures was approximately double the rate of general inflation as measured
by the Consumer Price Index. It is estimated that health care expenditures
exceeded $1 trillion, or approximately 14% of U.S. Gross Domestic Product, in
1995. Historically, cost containment efforts have focused on controlling
administrative costs even though approximately 65% of health care costs are
related to the clinical delivery of care (i.e., the costs directly associated
with the treatment of illness).

Clinical costs are driven by the choice of therapeutic resources and the
intensity and frequency of the delivery of such resources. The inappropriate or
excess consumption of therapeutic resources is referred to as "clinical
inefficiency." Clinical inefficiency manifests itself in many ways, including
clinically unjustified lengths of stay, excessive readmission rates,
above-average clinical complication and mortality rates, and excessive primary
care physician referrals to specialists.

Efforts to measure and control the clinical costs of health care
traditionally have been hampered by the lack of "benchmark" data required to
study the appropriateness, efficiency and effectiveness of health care delivery.
Structural changes and industry consolidation are driving the major health care
constituencies (providers, buyers and suppliers) to utilize information and
analytical tools to better measure clinical effectiveness. The increased
industry emphasis on "outcomes measurement" and "disease management" reflects
recognition of the need to properly understand and evaluate clinical costs.

Each of the major health care constituencies demands clinical information
for different reasons. In order to compete more effectively, providers are
increasingly demanding information that allows them both to measure the cost,
quality and outcome of the care they are delivering and to "benchmark" data to
measure performance against the industry's best practices. Buyers are
increasingly demanding a quality outcome at a fixed or capitated price for a
bundle of medical services. As a result, the overall efficiency and
effectiveness of the services delivered has become the central issue in the
selection of providers and in the continued analysis of the performance of
existing providers. Suppliers are increasingly required to demonstrate the
clinical and economic utility of their products when compared with alternatives
because of the increasing emphasis on costs and efficiency and the growing use
of mechanisms such as formularies to restrict physician drug choice.

<PAGE>
BUSINESS STRATEGY

HCIA's strategy is to maintain and extend its position as a leading
provider of content-based clinical information systems and products to all
market constituencies. Key elements of the Company's strategy are to:

BUILD RECURRING REVENUE. HCIA's marketing and pricing objectives are
focused on the generation of recurring revenue through multi-year contracts and
annually renewable contracts, as well as regular sales and updates of its
Syndicated Products. The Company's recurring revenue percentage for 1995 was
approximately 69%. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations -- Overview." The Company believes that the
high level of sophistication of its systems and products, combined with the
costs associated with switching to substitute information suppliers, encourage
its customers to continue their relationships with HCIA.

EXPAND THE SIZE AND SCOPE OF CUSTOMER RELATIONSHIPS. As a result of its
unique ability to integrate health care data collected from numerous sources and
across varied treatment settings, the Company believes that it is
well-positioned to offer the information systems and products necessary to
continue to increase average revenue per customer through the sale of more
sophisticated and comprehensive Decision Support Systems. The demand for more
sophisticated health care information systems and products has been driven by
the recognition of the need for more comprehensive information on costs,
outcomes and utilization to assess and manage risk while improving the quality
of care.

DEVELOP AND ACQUIRE NEW DATA RESOURCES AND TECHNOLOGIES. HCIA seeks to
develop and acquire new methodological, analytical and technical resources that
will continue to enhance the Company's ability to deliver clinical solutions. In
addition to its internal product development efforts, the Company seeks to
continue the acquisition of other data resources and technologies. The Company
intends to integrate and leverage these assets into product-line extensions
across its markets. The Company believes that its management and product-line
infrastructures, as well as its historical success in acquiring and assimilating
new products and companies, will allow it to continue the successful development
and acquisition of new systems and products.

DEVELOP STRATEGIC RELATIONSHIPS WITH KEY INDUSTRY PARTICIPANTS. HCIA seeks
to transcend the traditional customer-vendor relationship and forge long-term
alliances with key industry participants that are driving market evolution in
the health care industry. Through its strategic relationships with industry
leaders, the Company can add substantial value to its information systems and
products and promote the Company's proprietary data bases and methodologies as
an industry standard.

SYSTEMS AND PRODUCTS

HCIA's information systems and products are broadly classified as Decision
Support Systems, which contributed approximately 80% and 83% of revenue for 1995
and the three months ended March 31, 1996, respectively, and Syndicated
Products, which contributed approximately 20% and 17% of revenue for the same
respective periods. The Company offers its information systems and products
through a variety of media and distribution channels, including print, magnetic
media, CD-ROM and on-line access through SoleSourceTM, its client/server
workstation.

DECISION SUPPORT SYSTEMS

HCIA offers a range of Decision Support Systems, which are utilized by the
three major health care market constituencies:

PROVIDERS, such as hospitals, physician groups and integrated delivery
systems, use the Company's Decision Support Systems to measure and analyze the
cost and quality of medical interventions. The Company's entry-level Systems
provide customers with competitor specific information such as market share by
specialty, local market utilization rates compared with regional and national
norms and customer specific analyses of product line and physician level
resource consumption. High-end Decision Support Systems incorporate benchmarks
for specific medical resource consumption and are designed to help providers
understand the best practice for a medical intervention.

<PAGE>
BUYERS, such as managed care organizations, indemnity insurers and
self-insured employers, utilize the information and analyses on medical resource
usage and outcomes derived from the Company's Decision Support Systems to select
and monitor the performance of network providers, channel specific types of
patients towards the most clinically effective providers, and negotiate fair
prices and appropriate utilization criteria, as well as to manage the overall
health status of a covered population. The acquisitions of CHAMP and Response
have increased the Company's access to self-insured employers and managed care
organizations.

SUPPLIERS, such as pharmaceutical, biotechnology and medical supply and
device companies, utilize the Company's Decision Support Systems in market
analysis, product positioning and pharmacoeconomic analysis. Pharmacoeconomic
analysis provides suppliers with information needed to measure the specific
benefit/cost and outcome of an individual product against those of competing
products, alternative therapies or, in the case of a new drug or product, the
STATUS QUO therapy.

The Company's entry-level Systems are generally priced from $25,000
annually, while high-end Systems are generally priced from $250,000 to more than
$1.0 million annually. HCIA has entered into a number of strategic relationships
with state hospital associations, business partners such as HBO & Company
("HBOC"), and large users of data such as CIGNA Healthcare, Amgen Inc. and
Columbia/HCA.

HCIA's Decision Support Systems are based on the Company's DataBridgeTM
collection of data bases and data handling technologies and SoleSourceTM desktop
analytical software, and are supplemented by its clinical implementation
management team.

DATABRIDGE.TM DataBridgeTM is HCIA's collection of proprietary data bases
and data-handling technologies. A typical Decision Support System customer
submits data in an electronic, computer-readable format. In creating the
interface for the customer's data stream, HCIA enables the transfer of customer
data and the subsequent application of the Company's proprietary software
algorithms and data-standardization technologies to the incoming data,
transforming the data into HCIA's proprietary standardized formats. DataBridgeTM
has several components, including:

DATA BASE. A large number of the Company's customers are also its data
suppliers. Most of the Company's Decision Support System contracts provide that
as the Company extracts data from the customer (as part of the process of
delivering a system to the customer), the data become part of the Company's data
base. The Company supplements its data base with data it purchases or licenses
from federal and state governments, trade groups and other industry sources. The
Company maintains more than a terabyte of live health care data, including data
from medical records, laboratory, pharmacy, imaging, outpatient clinics,
physician's offices, insurance claims, managed care encounters and point-of-care
member patient surveys.

The Company's data base resides in a relational data base structure that
utilizes a network of large Sun Microsystems servers. The Company believes that
its current software and hardware platforms are scaleable and provide it with a
cost and flexibility advantage. The Company has made a significant investment in
an open-network architecture which links its several geographical locations and
provides customers with leased-line and dial-up access. The Company supports
most of the major relational data base platforms, such as Informix, Oracle, DB2,
Sybase and SQL Server.

The Company has personnel drawn from several key health care disciplines
(e.g., pharmacists, clinical nurses and medical technologists) who are
responsible for the auditing, editing and standardizing of its data base, as
well as the upgrading and maintaining of its core methodologies. The Company
believes that its data base provides more clinical detail and better outcomes
measurement capabilities than competitive systems. Furthermore, the detailed
medical content of the data and HCIA's experience in collecting and
standardizing this information provide additional competitive advantages.

The acquisitions of the CHAMP and Response data bases have significantly
expanded the Company's outpatient and episode-of-care capabilities. The
acquisition of LBA should significantly expand the Company's ICCS-level data
base through the addition of detailed clinical data from approximately 250
providers and provider groups which are LBA customers. As a result of
acquisitions and its internal growth, the Company believes that it has built one
of the largest and most sophisticated collections of integrated clinical,
financial and labor/productivity data in the health care industry.

<PAGE>
ICCS SYSTEM.TM The Company holds a perpetual and exclusive license to the
ICCS SystemTM, subject only to the Company's obligation to use all commercially
reasonable efforts to maintain and upgrade the system. The ICCS SystemTM assigns
a discrete and clinically detailed 12-digit code to every product and service
consumed in the treatment of patients. The Company believes that the ICCS
SystemTM is the health care industry's most widely implemented uniform
classification system for tracking and measuring the use of medical resources
(e.g., drugs, devices, laboratory tests, blood units, diagnostic imaging and
clinical services) across health care providers. The ICCS SystemTM allows for
the standardization and comparison of detailed clinical data, regardless of the
original source of the data (e.g., medical records, insurance claims, laboratory
or pharmacy systems). As of December 31, 1995, there were more than 69,600
separate ICCS codes, and, during the 12 months ended December 31, 1995, more
than 4,100 new codes were added to the ICCS SystemTM.

The ICCS SystemTM is used by the Company to create the most clinically
detailed portion of its data base. The Company develops a set of proprietary
software interfaces with each customer who is a supplier of such data. The
interfaces are built by a series of proprietary "data-mapping" applications that
incorporate the ICCS SystemTM and a series of algorithms that allow the mapping
applications to "learn" each time a new clinical item is encountered. In doing
so, the applications are able to automatically standardize more data each time a
new interface is created. As the volume of ICCS-level data entering the data
base expands, the efficiency of the interface-creation process increases. In
1990, the Company typically required more than six months to create an interface
to extract ICCS-level data. With more than 175 interfaces created to date, the
typical interface creation process has been reduced to less than six weeks.

Set forth below is an illustration of the application of the ICCS SystemTM
to the delivery of a common anti-infective drug.

<TABLE>

412020.232792 Dosage Unit Milligrams
</TABLE>

SOLESOURCE.TM SoleSourceTM is the Company's workstation that provides
customers with access to and analyses of information obtained with a Decision
Support System. SoleSourceTM utilizes Microsoft Foundation Classes Software and
accesses a variety of data base configurations, including Microsoft SQL Server,
Microsoft Access and Informix. As the Company has worked with a variety of
different health care organizations during the last several years (e.g.,
hospitals, managed care organizations and pharmaceutical companies), it has
developed an extensive library of proprietary health care data base
applications. In addition, as a result of the CHAMP, Response and LBA
acquisitions, the Company has recently expanded, and will continue to expand,
the scope of its data base applications. Depending on the customer, the size of
the data base and the sophistication of the Decision Support System, the Company
licenses various SoleSourceTM applications to customers as part of a Decision
Support System.

CLINICAL IMPROVEMENT METHODOLOGY AND MANAGEMENT. In addition to providing
data bases and application software, the Company, utilizing proprietary
methodologies, assists customers with the implementation of clinical solutions.
The Company's knowledge-based clinical improvement methodologies allow HCIA to
leverage its ICCS-level information and enable clients to realize improved
clinical outcomes and lower costs through

<PAGE>
the modification of medical and behavioral practice patterns. The Company's
methodologies link the costs, quality, utilization and outcomes of medical
services delivered to patients in various clinical settings and focus on
episodes of illness that offer the greatest opportunity for improving outcomes
and reducing costs.

As a result of the LBA acquisition, the Company will significantly expand
its clinical improvement methodologies and implementation management
capabilities. The Company also intends to integrate LBA's data bases,
methodologies and staff with HCIA's, creating additional leverage from its
ICCS-level data base and SoleSourceTM delivery platform. LBA's VALUE ENHANCEMENT
systems utilize data base analyses, clinical improvement methodologies and an
implementation management team of approximately 50 people to assist customers in
reducing clinical resource consumption and improving outcomes in major
specialties, including:

<TABLE>
<S> <C>
(Bullet) invasive cardiovascular (Bullet) vascular

(Bullet) orthopaedics (Bullet) neurosciences

(Bullet) oncology (Bullet) pulmonary

(Bullet) medical cardiology (Bullet) women's services
</TABLE>

In addition to its VALUE ENHANCEMENT systems, LBA assists hospitals in
obtaining Center of Excellence designation by HCFA. Center of Excellence
designation by HCFA conveys select medical status to high volume, premier
facilities in the practice areas of cardiology and orthopaedics. LBA's Centers
of Excellence program provides the necessary metrics, methodologies and data
bases to assist hospitals in achieving Center of Excellence designation for
specific clinical practice areas. The Company intends to enhance LBA's Centers
of Excellence program following the acquisition and believes that it will be
uniquely positioned to work with hospitals in motivating physicians and other
clinical practitioners to change behavior and achieve measurable improvements in
costs, outcomes, and clinical resource consumption -- the fundamental
requirements for Center of Excellence designation.

SYNDICATED PRODUCTS

Syndicated Products include publications and standardized databases which
are generally priced between $100 to $2,000, with certain Products priced up to
$25,000. The Products are developed from specific portions of the Company's data
base, and feature particular industry niches. Most Syndicated Products are sold
as annually renewable subscriptions or as multi-year contracts. Syndicated
Products range from data base directories (e.g., health care industry
professionals, nursing homes and managed care organizations) to more complex
analyses (e.g., cost and outcome summaries for each U.S. hospital).

HCIA also markets to managed care clients a number of more sophisticated
Syndicated Products containing national and regional normative data on length of
stay, costs and medical necessity. The Company markets these products directly
to managed care organizations, and through alliances with information systems
vendors, third-party administrators and other entities that process data streams
for managed care organizations and payors. These Syndicated Products generally
are used for utilization management, claims adjudication and actuarial
forecasting and generally result in annual revenue of $100,000 or more per
customer.

CUSTOMERS

The Company's customers include numerous health care industry participants
located throughout the United States and the United Kingdom, including major
provider and provider groups, managed care organizations, and pharmaceutical,
biotechnology and medical device companies. As of December 31, 1995, the Company
had more than 325 Decision Support System customers and more than 7,000
Syndicated Product customers. In 1994, one customer, Amgen Inc., accounted for
approximately 12% of the Company's revenue. In 1995, no single customer
accounted for 10% or more of the Company's revenue. HCIA's ten largest customers
accounted for approximately 29% and 36% of its revenue during 1994 and 1995,
respectively.

<PAGE>
SALES AND MARKETING

HCIA markets its information systems and products through a variety of
means that are designed to enhance its name recognition and facilitate the
marketing of additional systems and products to its customer base. The Company
utilizes a direct sales approach with the existing customer base to market its
Decision Support Systems. The Company's field sales force is highly specialized
and frequently draws on the Company's clinical implementation management team.
The field sales force seeks to present proposals in face-to-face meetings at the
executive level. In addition, HCIA has recently entered into agreements with
HBOC, Transition Systems and ActaMed, whereby the Company's Systems are marketed
through their respective sales forces.

The Company also approaches each of the major market constituencies through
the sale of lower-priced Syndicated Products. Many of these products, such as
the 100 TOP HOSPITALS study, are specifically designed to increase the
visibility of the Company as an industry-leading source of health care
information. The Company uses both telemarketing and direct-mail efforts in the
sales of its Syndicated Products.

HCIA continually seeks opportunities to create name recognition as a
leading provider of health care information. As part of this strategy, the
Company is widely quoted in the media, including publications such as THE WALL
STREET JOURNAL and MODERN HEALTHCARE, and its senior officers are frequently
asked to speak at industry conferences and serve on the editorial boards of
industry newsletters and publications.

COMPETITION

The Company believes that the principal competitive factors in the health
care information market are the breadth and quality of system and product
offerings, access to proprietary data, the proprietary nature of methodologies
and technical resources, price and the effectiveness of marketing and sales
efforts. In addition, the Company believes that the speed with which information
companies can anticipate and respond to the evolving health care industry
structure and identify information needs is an important competitive factor. The
Company believes that it competes favorably with respect to each of these
factors.

The market for health care information products and services is intensely
competitive. Competitors vary in size and in the scope and breadth of products
and services offered, and the Company competes for the sale of systems and
products and the resulting access to data with different companies in each of
its target markets. Many of the Company's competitors have significantly greater
financial, technical, product development and marketing resources than the
Company. Furthermore, other major information companies not presently offering
clinical health care information services may enter the markets in which the
Company competes.

The Company's potential competitors include specialty health care
information companies, health care information system and software vendors and
large data processing and information companies. Many of these competitors have
substantial installed customer bases in the health care industry and the ability
to fund significant product development and acquisition efforts.

INTELLECTUAL PROPERTY

HCIA considers its methodologies, computer software and data bases to be
proprietary. The Company seeks to protect its proprietary information through
confidentiality agreements with its employees. The Company's policy is to have
employees enter into confidentiality agreements containing provisions
prohibiting the disclosure of confidential information to anyone outside the
Company, requiring employees to acknowledge, and, if requested, assist in
confirming the Company's ownership of any new ideas, developments, discoveries
or inventions conceived during employment, and requiring assignment to the
Company of proprietary rights to such matters that are related to the Company's
business.

The Company also relies on a combination of trade secret, copyright and
trademark laws, contractual provisions in agreements with customers and
technical measures to protect its rights in various methodologies, systems and
products and data bases. The Company has not filed any patent applications or
copyright registration applications covering its software technology. Due to the
nature of its software applications, the Company believes that patent, trade
secret and copyright protection are less significant than the Company's ability
to further develop, enhance and modify its current systems and products.

<PAGE>
GOVERNMENT REGULATION

The FDA has promulgated a draft policy for the regulation of certain
computer products as medical devices. Although it is not possible to anticipate
the final form of the FDA's policy with regard to computer software, the Company
expects that, whether or not the draft policy is finalized, the FDA is likely to
become increasingly active in regulating computer software that is intended for
use in health care settings. The Company's products and product development
activities, therefore, could become subject to extensive regulation by the FDA.
The FDA regulates the introduction of new medical devices as well as activities
such as manufacturing, labeling and recordkeeping for such products. To the
extent that computer software is a medical device under FDA regulations or
policy, the Company would be required, depending on the product, to comply with
regulations, to (i) register and list the product with the FDA, (ii) notify the
FDA and demonstrate substantial equivalence to other products on the market
before marketing such products, or (iii) obtain FDA approval by demonstrating
safety and effectiveness before marketing a product. In addition, such products
would be subject to the FDA's general controls, including those relating to good
manufacturing practices and adverse experience reporting.

The process of obtaining clearance from the FDA can be costly and time
consuming, and there can be no assurance that, if required, such clearance
wouuld be granted for the Company's existing and future products on a timely
basis, if at all, or that FDA review will not include delays that would
adversely affect the Company's ability to market new products or to expand
permitted uses of existing products. The FDA could also limit or prevent the
manufacture or distribution of the Company's products and has the power to
require the recall of such products. FDA regulations depend heavily on
administrative and scientific interpretation, and there can be no assurance that
future interpretation made by the FDA or other regulatory bodies, with possible
prospective and retroactive effect, will not adversely affect the Company.

The confidentiality of patient records and the circumstances under which
such records may be released for inclusion in the Company's databases is subject
to substantial regulation by state governments. These state laws and regulations
govern both the disclosure and use of confidential patient medical record
information. Although compliance with these laws and regulations is principally
the responsibility of the hospital, physician or other health care provider
supplying the data to the Company, the Company's databases have been designed to
enable health care providers to comply with the confidentiality of state law.
The Company believes that its procedures comply with the laws and regulations
regarding the collection of patient data in substantially all jurisdictions.
However, additional legislation governing the dissemination of medical record
information has been proposed at both the state and federal level. This
legislation may require holders of such information to implement security
measures that may be of substantial cost to the Company. There can be no
assurance that changes to state or federal laws will not materially restrict the
ability of health care providers to submit information from patient records to
the Company.

EMPLOYEES

As of June 30, 1996, the Company had 588 employees, including 59 in sales
and marketing, 335 in health care data, 110 in technology and 84 in finance and
administration. None of the Company's employees are represented by a union or
other bargaining group. The Company believes its relationships with its
employees to be satisfactory. As of June 30, 1996, LBA had 162 employees, none
of whom are represented by a union or other bargaining group.

PROPERTIES

The Company's executive and corporate offices are located in Baltimore,
Maryland, in approximately 57,000 square feet of leased office space, under a
lease that expires on December 31, 2002, and which includes an option for an
additional term of up to five years. The Company also leases approximately
36,500 square feet of office space in Ann Arbor, Michigan, under a lease that
expires on March 31, 2000. The Company also maintains seven other offices in the
United States and three offices in Europe. LBA maintains corporate offices in
Denver, Colorado, in approximately 27,500 square feet of leased office space
under a lease that expires on September 30, 1998. The Company believes that its
facilities are adequate for its current operations.

<PAGE>
LITIGATION

The Company is a defendant from time to time in lawsuits incidental to its
business. The Company is not currently a party to, and none of its properties is
subject to, any material legal proceedings.

A current minority stockholder of HealthVISION has threatened suit in
connection with the purchase by HealthVISION in September 1995 of the assets of
the predecessor of LBA. The outcome of this matter cannot be predicted with
certainty at this time. In connection with the distribution by HealthVISION of
its assets and liabilities not associated with LBA, the assignee of such assets
and liabilities has agreed to indemnify and hold HealthVISION, LBA and HCIA
harmless from and against any liability associated with the potential claim.
Certain current stockholders of HealthVISION have guaranteed such indemnity.

EMPLOYMENT AGREEMENT

Effective as of January 1, 1995, the Company entered into an employment
agreement with Mr. Pillari pursuant to which the Company continued his
employment as Chairman of the Board, President and Chief Executive Officer.
Pursuant to the employment agreement, Mr. Pillari receives an annual base salary
of $265,000 and is entitled to participate in bonus arrangements under which he
is eligible to earn an annual bonus based on the Company's achieving certain
performance goals to be established by the Board of Directors. The employment
agreement has an initial term of two years, and unless the Board of Directors
notifies Mr. Pillari otherwise, the term of the agreement automatically renews
daily for succeeding two year periods.

The employment agreement provides that in the event of the termination of
Mr. Pillari's employment for certain reasons, including certain terminations
resulting from a change in control of the Company (as defined in the employment
agreement), Mr. Pillari would be entitled to receive for the remainder of the
employment term contemplated in the agreement, compensation at an annualized
rate equal to the sum of his base annual salary and target bonus at the time of
termination (such sum being not less than 140% of such base annual salary). In
addition, he would continue to participate in all Company benefit plans until
the earlier of two years from the date of termination or such time as he is
covered by a comparable plan of a subsequent employer. Mr. Pillari is also
subject to certain restrictions under the agreement prohibiting him from
competing with the Company or any of its subsidiaries and from divulging any
confidential proprietary information obtained by him while in the employ of the
Company and for a period of time thereafter.

MANAGEMENT RETENTION AGREEMENTS

The Company has entered into a management retention agreement with each of
its officers (other than Mr. Pillari). These agreements provide for payments and
other benefits if there is a change in control (as defined in

<PAGE>
the agreement) of the Company and, within two years of such change in control,
the officer's employment is terminated by the Company or its successor other
than for cause (as defined in the agreement), or the officer resigns for good
reason (as defined in the agreement). Under each agreement, the officer would
receive, following termination of employment under such circumstances, cash
payments equal to two times the sum of (i) the officer's highest annual rate of
base salary, and (ii) the product of the officer's highest bonus percentage (as
a percentage of base salary) times his highest base salary (such sum being the
"Reference Amount"). The officer may elect to receive payment of one times the
Reference Amount either in a lump sum or in the form of periodic payments
following his termination of employment. Amounts in excess of one times the
Reference Amount will be made in the form of periodic payments, and will be
subject to reduction, on a dollar-for-dollar basis, by any compensation the
officer earns from a subsequent employer unrelated to the Company.

In addition to the payments described above, the officer would be fully
vested in all stock options and other Awards under the HCIA 1994 Stock and
Incentive Plan (the "Stock Option Plan") upon a change in control and would
receive following termination of employment a lump-sum payment equal to the
amount that the Company would have contributed for the officer's account under
the Company's Savings Incentive Plan during the two years following termination
of employment. The officer and his family will remain eligible to participate in
the Company's medical and other welfare benefits programs for two years from the
officer's termination of employment (except that coverage will end to the extent
the officer begins coverage under the plans of a subsequent employer).

STOCK OPTIONS

NON-PLAN OPTIONS. The Company has granted non-qualified options (the
"Options"), pursuant to individual stock option award agreements, to certain of
its past and present employees (the "optionees") to purchase shares of the
Company's Common Stock. Options were granted in December 1992, and in February,
April and October 1994 (collectively the "Options"). The Options granted in
October 1994 expire on October 21, 2004. The remainder of the Options expire on
July 1, 2000.

The Options have exercise prices ranging from $6.00 to $10.50 per share.
With respect to the Options granted in December 1992 and February and April
1994, 50% of the shares of Common Stock may be exercised on or after February
22, 1996 and the balance of the Options may be exercised on or after February
22, 1997. The Options granted in October 1994 become exercisable upon their
vesting, which is over a three-year period which commenced in October 1995.
Under the Options, if the optionee's employment with the Company terminates for
any reason other than death or permanent disability (as defined in the option
agreement), the Option shares not vested are forfeited. If the optionee's
employment terminates by reason of death or permanent disability prior to the
vesting of an Option, the Option is fully vested as of the date of death or
termination due to permanent disability. The Options granted in October 1994
also vest in full if the optionee's employment terminates due to retirement.

The Company's Chief Executive Officer was granted, in connection with the
Company's initial public offering, a non-plan option to purchase 160,000 shares
of Common Stock at an exercise price equal to the initial public offering price
of $14.00 per share. This option is exercisable in full and will expire on
February 22, 2000.

STOCK OPTION PLAN. The Company's Stock Option Plan was approved by the
Board of Directors on December 22, 1994 and thereafter by the Company's
stockholders. At the Company's 1996 Annual Meeting of Stockholders, to be held
on August 7, 1996, the stockholders of the Company will consider an amendment to
the Stock Option Plan to increase the number of shares available for awards to
1,350,000 shares. The Stock Option Plan provides for the grant or award of stock
options, stock appreciation rights, restricted stock, restricted stock units and
other performance awards which may or may not be denominated in shares of Common
Stock or other securities (collectively, the "Awards"). Stock options granted
under the Stock Option Plan may be either incentive stock options or
non-qualified options. The purpose of the Stock Option Plan is to attract and
retain outstanding employees through the incentives of stock ownership and
monetary payments. Any regular full-time employee of the Company, including
officers but excluding directors who are not officers, is eligible to receive
awards.

<PAGE>
The Stock Option Plan is administered by the Compensation Committee.
Subject to the provisions of the Stock Option Plan, the Compensation Committee
has the authority to designate participants, determine the types of Awards to be
granted, the number of shares to be covered by each Award, the time at which
each Award is exercisable or may be settled, the method of payment and any other
terms and conditions of the Awards. All Awards shall be evidenced by an Award
Agreement between the Company and the participant.

While the Compensation Committee determines the prices at which options and
other Awards may be exercised under the Stock Option Plan, the exercise price of
an option shall be at least 100% of the fair market value (as determined under
the terms of the Stock Option Plan) of a share of Common Stock on the date of
grant. The aggregate number of shares of Common Stock available for awards under
the Plan is currently 450,000 and will increase to 1,350,000 if the plan
amendment is approved by stockholders. No Awards may be made under the Stock
Option Plan after December 31, 2004.

DIRECTORS OPTION PLAN. Under the HCIA 1995 Non-Employee Directors Stock
Option Plan (the "Directors Option Plan"), each director who is not an officer
or employee of the Company or its affiliates (an "outside director") is
initially granted an option to purchase 4,500 shares of Common Stock at an
exercise price equal to the fair market value of the Common Stock at the time of
grant. In addition, each current outside director, and each person who is
subsequently elected as an outside director, will be granted an option at each
annual meeting of stockholders to purchase 1,500 shares of Common Stock at an
exercise price equal to the fair market value on the date of grant. A total of
100,000 shares of Common Stock are currently available for awards under the
Plan. At the Company's 1996 Annual Meeting of Stockholders, the stockholders of
the Company will consider amendments to the Directors Option Plan to increase
the number of shares available for award to 200,000 shares, the award for a
newly elected or appointed outside director to 5,000 shares, and the annual
option award for each outside director to 5,000 shares.

<PAGE>

The Representatives have advised the Company that they propose initially to
offer the shares of Common Stock to the public at the public offering price set
forth on the cover page of this Prospectus, and to certain dealers at such price
less a concession not in excess of $ per share. The Underwriters may allow,
and such dealers may reallow, a discount not in excess of $ per share to
certain other dealers. After the initial public offering, the public offering
price, concession and discount may be changed.

<PAGE>
The Company has granted the Underwriters an option exercisable for 30 days
after the date of this Prospectus to purchase up to an aggregate of 332,505
additional shares of Common Stock at the public offering price set forth on the
cover page of this Prospectus, less the underwriting discount. The Underwriters
may exercise this option only to cover over-allotments, if any, made on the sale
of the shares of Common Stock offered hereby. If the Underwriters exercise this
option, each of the Underwriters will have a firm commitment, subject to certain
conditions, to purchase approximately the same percentage thereof which the
number of shares of Common Stock to be purchased by it shown in the foregoing
table is of the 2,216,696 shares initially offered hereby.

The Company and certain officers of the Company and HealthVISION have
agreed not to offer, sell, contract to sell or otherwise dispose of, directly or
indirectly, or file or cause to be filed a registration statement under the
Securities Act with respect to, any shares of Common Stock, securities
convertible into, exchangeable for or repayable with such shares or rights or
warrants to acquire such shares, for a period of 90 days after the date of this
Prospectus without the prior written consent of Merrill Lynch, Pierce, Fenner &
Smith Incorporated, except that the Company may, without such consent, grant
options pursuant to the Stock Option Plan and the Directors Option Plan or issue
shares of Common Stock upon exercise of options currently outstanding, or issue,
or file registration statements with respect to, up to a specified number of
shares of Common Stock in connection with acquisitions under certain
circumstances.

In connection with the Offering, certain Underwriters (and selling group
members, if any) may engage in passive market making transactions in the Common
Stock on NASDAQ in accordance with Rule 10b-6A under the Exchange Act. Rule
10b-6A permits, upon satisfaction of certain conditions, underwriters and
selling group members participating in a distribution that are also NASDAQ
market makers in the security being distributed to engage in limited market
making transactions during the period when Rule 10b-6 under the Exchange Act
would otherwise prohibit such activity. Rule 10b-6A prohibits underwriters and
selling group members engaged in passive market making, generally, from entering
a bid or effecting a purchase at a price that exceeds the highest bid for those
securities displayed on NASDAQ by a market maker that is not participating in
the distribution. Under Rule 10b-6A, each underwriter or selling group member
engaged in passive market making is subject to a daily net purchase limitation
equal to 30% of such entity's average daily trading volume during the two full
consecutive calendar months immediately preceding the date of the filing of the
registration statement under the Securities Act pertaining to the security to be
distributed.

The Company and the Selling Stockholders have agreed to indemnify the
Underwriters against certain liabilities, including liabilities under the
Securities Act, or to contribute to payments the Underwriters may be required to
make in respect thereof.

LEGAL MATTERS

The validity of the Common Stock being offered hereby will be passed upon
for the Company and Selling Stockholders by Whiteford, Taylor & Preston L.L.P.,
Baltimore, Maryland. Certain legal matters in connection with the Offering will
be passed upon for the Underwriters by Brown & Wood LLP, New York, New York.

INDEPENDENT AUDITORS' REPORT

The Board of Directors
HCIA Inc.:

We have audited the accompanying consolidated balance sheets of HCIA Inc.
and subsidiaries as of December 31, 1994 and 1995, and the related consolidated
statements of operations, changes in stockholders' equity and cash flows for
each of the years in the three-year period ended December 31, 1995. These
consolidated financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of HCIA Inc.
and subsidiaries as of December 31, 1994 and 1995, and the results of their
operations and their cash flows for each of the years in the three-year period
ended December 31, 1995 in conformity with generally accepted accounting
principles.

As discussed in Notes 2 and 8 to the consolidated financial statements, the
Company changed its method of accounting for income taxes in 1993 to adopt the
provisions of the Financial Accounting Standard Board's Statement of Financial
Accounting Standards No. 109, "Accounting for Income Taxes."

HCIA INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

DECEMBER 31, 1993, 1994 AND 1995

(1) BACKGROUND

(a) DESCRIPTION OF BUSINESS

HCIA Inc. ("HCIA" or the "Company") is a health care information content
company that develops and markets integrated clinical information systems and
products. The Company's systems and products range from standardized data bases
to highly focused Decision Support Systems that assist its customers in
evaluating the efficacy and economics of health care delivery. The Company's
customers include hospitals, integrated delivery systems, self-insured
employers, pharmaceutical companies and managed care organizations.

(b) PUBLIC OFFERINGS

During February 1995, the Company completed an initial public offering of
approximately 2.0 million shares of Common Stock at $14.00 per share. In August
1995, the Company completed a second public offering of approximately 2.6
million shares at $28.50 per share. The second public offering consisted of 1.5
million shares issued by the Company and approximately 1.1 million shares sold
by the Company's largest stockholder, AMBAC Inc. ("AMBAC").

On April 28, 1995, the Company acquired all of the capital stock of Datis
Corporation ("Datis") for $14,250,000 in cash. Datis provides databases and
related analyses to hospitals and hospital systems. The acquisition was
accounted for using the purchase method of accounting and resulted in increases
in current assets of $1,338,000, furniture and equipment of $1,092,000, other
assets of $25,000, software of $233,000 and other intangible assets of
$16,503,000; offset by increases in current liabilities of $4,671,000 and long
term liabilities of $270,000. Substantially all of the other intangible assets
recorded in connection with this acquisition relate to goodwill. The goodwill is
being amortized over its estimated useful life of 20 years. The estimate of the
amortization period is based on the nature of the products and markets of Datis
and the historical rate of change in the products and markets. Funding for the
acquisition was provided from the proceeds of the Company's initial public
offering.

During November 1995, the Company acquired an additional 36% interest in
CHKS Limited ("CHKS"). As a result of this acquisition, CHKS became a
wholly-owned subsidiary of the Company. The Company issued notes payable to the
former shareholders in the amount of $2,795,000. The purchase agreement also
provides for an additional payment to the former shareholders in the event that
certain operational performance targets are met by CHKS during 1996. This
acquisition was accounted for using the purchase method of accounting and
resulted in additional goodwill of $2,709,000. The goodwill is being amortized
over its estimated useful life of 15 years. The estimate of the amortization
period is based on the nature of the products and markets of CHKS and the
historical rate of change in the products and markets.

On December 15, 1995, the Company acquired the assets constituting the
CHAMP unit of William M. Mercer, Incorporated for $17,500,000 in cash. The CHAMP
unit provides data base and analytical reporting services to large employers to
assist them in the management of their health care costs. The acquisition was
accounted for using the purchase method of accounting and resulted in an
increase in software of $859,000 and other intangible assets of $4,489,000. The
other intangible assets consist of trade names of $1,266,000, assembled
workforce of $1,102,000, customer base of $595,000 and goodwill of $1,526,000.
These assets are being amortized on a straight-line basis over 12 years. The
lives of these assets were determined by an independent appraiser based on,
among other things, employee turnover, historical customer retention rates and
the historical rate of change in the products and markets. At the date of the
acquisition, the Company recorded a non-recurring charge of $12,152,000 relating
to in-process research and development costs which were acquired in this
acquisition.

F-7

<PAGE>
HCIA INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

These costs related to the development of a client server based system to
process and deliver health care data and analysis tools to CHAMP customers. The
amount of the non-recurring charge was equal to the estimated current fair
value, based on the risk adjusted cash flows (at a discount rate of 20%, which
included cost of capital of 18% and an incremental risk premium of 2%), of
specifically identified technologies for which technological feasibility had not
yet been established pursuant to Statement of Financial Accounting Standards No.
86, "Accounting for the Costs of Computer Software to be Sold, Leased or
Otherwise Marketed," and for which future alternative uses did not exist.
Consideration of technological feasibility for purposes of this calculation was
done on a basis consistent with that normally utilized by the Company (See Note
2(d)). This charge is recorded as an operating expense on the accompanying
consolidated statement of operations for the year ended December 31, 1995.
Funding for this acquisition was provided from the proceeds of the Company's
public offerings.

During 1995, the Company also acquired certain assets and assumed certain
liabilities of John Froehlich Associates, MetriCor Inc. and MetaGenerics. The
aggregate purchase price for these acquisitions was $1,677,000, consisting of
cash of $1,166,000 and notes payable of $511,000. These acquisitions were
accounted for using the purchase method of accounting and resulted in increases
in furniture and equipment of $75,000, increases in other intangible assets of
$1,938,000 and increases in current liabilities of $336,000. The other
intangible assets consist of goodwill which is being amortized on a
straight-line basis over estimated useful lives of 10 to 15 years. The estimate
of each amortization period is based on the nature of the products and markets
of the acquired entities and the historical rate of change in the products and
markets. Funding for these acquisitions was provided from the proceeds of the
Company's public offerings.

Unaudited pro forma combined results of the operations of the Company for
the years ended December 31, 1995 and 1994 are presented below and have been
prepared assuming that the acquisitions discussed above had been made as of
January 1, 1994.

</TABLE>

The pro forma results include the historical accounts of the Company and
the acquired entities adjusted to reflect the effects of the depreciation and
amortization of the acquired identifiable tangible and intangible assets based
on the new cost basis of the assets acquired, additional interest expense
related to notes payable issued in connection with certain acquisitions, the
reversal of the non-recurring write-off of acquired in-process research and
development costs recorded in connection with the CHAMP acquisition and the
related income tax effects. The pro forma results are not necessarily indicative
of actual results which might have occurred had the operations and management of
the Company and the acquired entities been combined in 1994 and 1995.

(d) DIVESTITURE

Effective January 1, 1994, the Company sold certain of its software product
lines at their approximate book value to a company formed by a group of the
Company's former employees. These product lines generated revenues of
approximately $3.0 million during the year ended December 31, 1993. In
connection with the sale, the Company received a note in the amount of
$1,659,000 and also purchased a 49% equity interest in the new entity for
$120,000. During 1995, the Company received payment in full on the balance
outstanding on the note and sold the equity interest back to the entity for
$139,000, representing the original investment of $120,000 plus interest for the
period the equity interest was held.

(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

(a) PRINCIPLES OF CONSOLIDATION

The accompanying financial statements include the accounts of the Company
and its subsidiaries. The minority interest of CHKS for the periods before it
became wholly-owned is stated separately on the financial statements. All
significant intercompany transactions have been eliminated in consolidation.

(b) CASH EQUIVALENTS AND SHORT-TERM INVESTMENTS

Cash equivalents consist of highly liquid securities with original
maturities of three months or less at the date acquired by the Company. At
December 31, 1995, the Company's short-term investments, which are classified as
available for sale securities portfolio, consist of the following:

<TABLE>
<CAPTION>
FAIR VALUE COST
---------- ----
<S> <C> <C>
Auction Market Preferred Stock............................ $ 7,000,000 $ 7,000,000
Variable Rate Debentures.................................. 5,500,000 5,500,000
Municipal Bonds........................................... 10,780,000 10,736,000
------------ ------------
Total................................................... $ 23,280,000 $ 23,236,000
============ ============
</TABLE>

The portfolio is carried at fair value in accordance with Statement of
Financial Accounting Standards No. 115, "Accounting for Certain Investments in
Debt and Equity Securities." All securities mature within one year. Gross
unrealized gains and losses were $44,000 and $0, respectively, and are included
as a separate component of stockholders' equity. Realized gains and losses are
recorded using the specific identification basis to determine costs. During
1995, proceeds from sales of the securities totalled $46,677,000, gross realized
gains totalled $2,000 and gross realized losses totalled $0.

Furniture and equipment are stated at cost. Included in furniture and
equipment are computer hardware, furniture and fixtures and leasehold
improvements. These costs are being depreciated on the straight-line method over
their estimated useful lives of three to five years.

(d) COMPUTER SOFTWARE COSTS

Computer software costs include the cost of internally developed software
and the fair market value assigned to computer software obtained in purchase
transactions. Costs for internally developed software are capitalized in
accordance with Statement of Financial Accounting Standards No. 86, "Accounting
for the Costs of Computer Software to be Sold, Leased or Otherwise Marketed."
These costs relate primarily to the building of production systems and extending
existing applications to new markets or platforms using existing technologies
and programming methods. The Company capitalizes only those costs incurred after
a detailed program design or, in the absence of such, a working prototype has
been developed. The Company generally develops its applications in connection
with customer contracts and includes the related costs as a component of
operating expenses in the period incurred. The Company capitalized or purchased
a total of $2,236,000, $2,603,000 and $7,260,000 of computer software costs in
1993, 1994 and 1995, respectively, including $1,109,000 in 1995 related to
business acquisitions.

Capitalized costs are amortized, beginning with market availability, over
the economic useful life of the product. Typically, this life is five years. The
annual amortization expense is the greater of the amount computed using (a) the
ratio that current gross revenues for a product bears to the total of current
and anticipated future gross revenues for that product or (b) the straight-line
method over the remaining estimated economic life of the product including the
period being reported. Amortization expense for computer software was
$1,540,000,

F-9

<PAGE>
HCIA INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

$1,456,000 and $2,048,000 during 1993, 1994 and 1995, respectively. Accumulated
amortization for computer software was $4,462,000 and $6,510,000 at December 31,
1994 and 1995, respectively.

The Company evaluates, on a quarterly basis, the recoverability of
capitalized software costs on the basis of whether such costs are fully
recoverable from projected undiscounted cash flows of individual system and
product lines.

(e) REVENUE RECOGNITION

Revenue from license fees for access to the Company's data bases is
recognized when access to the data base is made available to the customer.
Revenue from custom system or data base development and implementation contracts
is recognized on a percentage of completion basis using the cost to cost method.
On a quarterly basis, the Company assesses whether the current estimate of total
contract costs for each of these contracts indicates a loss is expected and
accrues any such losses on the entire contract in that quarter. Where the
Company has contracted to provide both access to a Company data base and
development of a custom data base, the contract value is segmented into its
discrete elements according to their relative values, and revenue is recognized
separately on each element in accordance with the above.

Revenue from group data contracts, which obligate the Company to process
data, produce reports and update data bases on periodic intervals, is recognized
as the contracted obligations are fulfilled.

Revenue from licensing of software products is recognized upon shipment,
provided that no vendor obligations remain outstanding. While the Company has no
significant post-contract support (PCS) obligations, any revenue related to
insignificant PCS obligations on software licenses is deferred and recognized
over the contract term. The Company determines the component of revenue
applicable to PCS obligations based upon its experience in fulfilling such
obligations.

Revenue on all other products is recognized when the product is shipped.

During 1993 and 1994, one customer accounted for 12% of the Company's
revenue. At December 31, 1994, receivables from that customer represented 12% of
the Company's trade accounts receivable. Consistent with Company policy, no
collateral or other security was held with respect to such trade accounts
receivable. During 1995, no single customer accounted for 10% or more of the
Company's revenue or trade accounts receivable.

(f) FOREIGN CURRENCY TRANSLATION

The assets and liabilities of CHKS are translated at year-end exchange
rates, while revenue and expenses are translated at rates prevailing during the
period. Accordingly, translation adjustments that arise due to fluctuations in
exchange rates are excluded from operations and are reported as a separate
component of stockholders' equity.

(g) INCOME TAXES

Prior to the completion of the Company's initial public offering in
February 1995, the Company was party to a federal tax-sharing agreement with
AMBAC and was included in AMBAC's consolidated federal income tax return. The
tax-sharing agreement provided for the determination of tax expense or benefit
based on the contribution of the Company to AMBAC's tax liability, computed
substantially as if the Company filed a separate income tax return. The tax
liability due AMBAC was settled quarterly, with a final settlement taking place
after the filing of the consolidated federal tax return. Commencing February 22,
1995, the Company is no longer included on a consolidated basis for tax purposes
with AMBAC and is responsible for filing its own federal income tax return.

Effective January 1, 1993, the Company adopted Statement of Financial
Accounting Standards No. 109, "Accounting for Income Taxes" ("SFAS No. 109"),
and the cumulative effect of this change as of that date is reported in the
consolidated statement of operations for 1993.

F-10

<PAGE>
HCIA INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

Under SFAS No. 109, the Company uses the asset and liability method to
account for deferred income taxes. Under this method, deferred income taxes are
recognized for temporary differences between the financial reporting bases of
assets and liabilities and their respective tax bases and for operating loss and
tax credit carryforwards based on enacted rates expected to be in effect when
such amounts are realized or settled. The effects of changes in tax laws or
rates on deferred tax assets and liabilities are recognized in the period that
includes the enactment date.

(h) EARNINGS PER SHARE

Earnings per share has been calculated based upon the weighted average
number of shares outstanding and using the treasury stock method for outstanding
stock options. The number of shares used in this calculation has been adjusted
to reflect a one-for-three reverse stock split and the conversion of Class A and
Class B common stock into a single class of common stock (see note 10). For
1994, the fair market value per share for the purpose of the calculation of the
weighted average shares outstanding was assumed to be $11.00, which was the
mid-point of the initial public offering price range.

(i) USE OF ESTIMATES

Management of the Company has made a number of estimates and assumptions
relating to the reporting of assets and liabilities and the disclosure of
contingent assets and liabilities to prepare these financial statements in
conformity with generally accepted accounting principles. Actual results could
differ from those estimates.

(j) RECLASSIFICATIONS

Certain amounts for 1993 and 1994 have been reclassified to conform to the
presentation for 1995.

(3) FURNITURE AND EQUIPMENT

Furniture and equipment consist of the following at December 31:

$51,426,000 $9,088,000 $ 42,338,000
=========== ========== ============
</TABLE>

Data bases consist of the fair market value of various data bases acquired
through acquisitions, the cost of acquiring data and internal development costs
(direct labor and related overhead) incurred in standardizing data for use in
internally developed data bases. These assets are being amortized on a
straight-line basis over their estimated useful lives of five years.
Amortization expense for data bases was approximately $849,000, $839,000 and
$962,000 during 1993, 1994 and 1995, respectively.

During 1992, the Company acquired an exclusive license to access and sell
the data bases and certain other assets of the Commission on Professional and
Hospital Activities ("CPHA"). This license was recorded at its estimated fair
value of $8,073,000 at the date of acquisition and is being amortized on a
straight-line basis over 17 years. The amortization period was determined to be
the estimated economic life cycle of the licensed properties, as corroborated by
an independent appraisal, and reflected the remainder of the existing term of
the license at the date of acquisition plus one renewal term provided under the
terms of the agreement.

Under the terms of the license, the Company paid royalties to CPHA based on
revenues earned utilizing the licensed assets. Subsequent to the acquisition,
the Company and CPHA entered into a new license agreement. Under the terms of
the new agreement, the Company paid $5,958,000 to CPHA in lieu of future royalty
obligations. The payment is recorded as prepaid CPHA royalties and is being
amortized on a straight-line basis over 17 years, consistent with the estimated
economic life of the licensed properties.

Goodwill represents the excess of the purchase price over the fair value of
net assets acquired. Goodwill is being amortized on a straight-line basis over
10 to 20 years. Such amortization periods are estimated based on the nature of
the products and markets of the acquired companies and the historical rates of
changes in these products and market areas.

Other intangibles consist of noncompetition agreements and identifiable
intangible assets obtained through acquisitions. The noncompetition agreements
are amortized over their 1 to 2 year terms. Certain of the noncompetition
agreements are with the original stockholders of the acquired company who are
still employed by the Company or AMBAC as of December 31, 1995. Amortization of
these agreements, which are valued at $684,000, will commence when the
stockholders are no longer employees of AMBAC or the Company. The acquired
identifiable intangible assets consist of trade names, assembled workforce,
customer base and methodologies. The trade names, assembled workforce and
customer base were obtained through the CHAMP acquisition, and are being
amortized over 12 years. The lives of these assets were determined by an
independent appraiser based on factors such as going concern value, employee
turnover and historical customer retention rates. The methodologies are being
amortized over their estimated useful lives of 5 years.

(7) SAVINGS INCENTIVE PLAN

The Company maintains the HCIA Inc. Savings Incentive Plan, a profit
sharing plan qualified under Section 401(a) of the Internal Revenue Code. All
employees of the Company who have completed one year of service are eligible to
participate in the Plan. Subject to certain limitations on individual
contributions and allocations and Company deductions, the Plan allows
participants to defer up to 15% of their pay on a pre-tax basis and up to 10% of
their pay on an after-tax basis. The Company also makes matching contributions
equal to 50% of the amount a participant defers up to 4% of the participant's
pay. The Plan also provides for discretionary contributions by the Company. All
participants are fully vested in all of their accounts in the Plan. The
Company's contributions to the Plan during 1993, 1994 and 1995 were
approximately $155,000, $167,000, and $194,000, respectively.

(9) LINE OF CREDIT

The Company has entered into a line of credit agreement with a bank which
allows for maximum borrowings of $4,000,000. The line of credit is secured by
accounts receivable and bears interest at the bank's prime rate

plus 0.25% (8.75% as of December 31, 1995) and expires on January 2, 1997. The
Company also pays a commitment fee on the average daily unused portion of the
line of credit at a rate of 0.25% per annum. As of December 31, 1995 there had
been no borrowings under the line of credit.

(10) STOCKHOLDERS' EQUITY

(a) CAPITAL AMENDMENT

Effective February 14, 1995, the Company filed an amendment to its articles
of incorporation which effected: (i) a one-for-three reverse stock split; (ii)
the conversion of the Class A and Class B common stock into a single class of
common stock; and (iii) the authorization of a total of 15,000,000 shares of
common stock and 500,000 shares of preferred stock, each having a par value of
$.01 per share. All references to common stock and stock options in these
financial statements have been adjusted to reflect the one-for-three reverse
stock split as if it had occurred prior to January 1, 1993.

(b) COMMON AND PREFERRED STOCK

The preferred stock may be issued from time to time by the board of
directors as shares of one or more series. The description of the shares of each
series of preferred stock is established by the board of directors prior to the
issuance of the series of shares.

During 1993, the Company issued 30,000 shares of Series B, 6% cumulative
preferred stock to AMBAC Indemnity Corporation ("AIC").

During 1994, the Company issued 2,378,672 shares of common stock to AIC in
exchange for the 225,621 shares of preferred stock then outstanding.

During 1995, the Company issued 3,512,500 shares of common stock in
connection with its public offerings.

At December 31, 1994 and 1995, the Company had outstanding stock options as
follows:

<TABLE>
<CAPTION>
1994 1995
-------- --------
<S> <C> <C>

Other options................................................................... 374,226 507,800
------- -------
Total stock options outstanding................................................. 374,226 700,233
======= =======
</TABLE>

The HCIA Stock Option Plan provides that up to 450,000 options may be
issued to employees of the Company. Options granted to date under this plan vest
over a period of three or four years. The Directors Option Plan provides that
100,000 options may be issued to outside directors of the Company. Options
granted to date under this plan vest over a period of two years. The Company has
also issued non-plan options which generally vest over periods of two or three
years. In February 1995, the Company issued a non-plan option to its chief
executive officer which was fully vested on the date of grant. All stock options
issued by the Company have been granted with exercise prices equal to or greater
than the estimated fair market value of the common stock on the date of grant;
accordingly, the Company has recorded no compensation expense related to such
grants. Stock option transactions are summarized as follows:

(11) RELATED PARTY TRANSACTIONS

In January 1993 and 1994, the Company executed credit agreements with
AMBAC. The credit agreement entered into in January 1994 replaced the prior
agreement and extended a revolving line of credit of $2.5 million (subject to
certain borrowing base limitations) at a rate based upon the prime rate of
Citibank, N.A. in New York, New York. The Company was also required to pay AMBAC
a commitment fee on the average daily unused portion of the line of credit at a
rate of 0.25% per annum. The Company utilized approximately $1.9 million of the
proceeds from its initial public offering to repay the outstanding borrowings
under the credit agreement. The credit agreement was terminated in May 1995.

Until August 1995, the Company maintained its business insurance, including
property, general liability, automobile, workers' compensation and fidelity and
fiduciary coverage (including officers' and directors' liability insurance)
through AMBAC, which purchased insurance coverage for the Company. The Company
was charged its pro rata share of premiums. The amounts of premiums paid to
AMBAC by the Company were $90,000, $72,000 and $89,000 for policy years 1993,
1994 and 1995, respectively.

AIC purchases information services from the Company. Such purchases totaled
$262,000, $288,000 and $250,000 during 1993, 1994 and 1995, respectively.

(12) DISCLOSURES ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS

The carrying amount of cash and cash equivalents, trade accounts
receivable, other current assets, accounts payable, accrued expenses and capital
lease obligations approximates fair value because of the short-term maturity of
these instruments. The fair value of short-term investments is estimated based
on quoted market prices for these or similar investments. The Company has notes
receivable from and notes payable to individuals relating to certain of its
business acquisitions. It is not practicable to estimate the fair value of these
notes since they are not traded, no quoted values are readily available for
similar financial instruments and the Company believes it is not cost-effective
to have valuations performed. However, management believes that there has been
no permanent impairment in the value of such notes.

(13) NEW FINANCIAL ACCOUNTING STANDARDS

In October 1995, Statement of Financial Accounting Standards No. 123,
"Accounting for Stock-based Compensation" ("SFAS No. 123"), was issued. This
statement requires the fair value of stock options and other stock-based
compensation issued to employees to either be included as compensation expense
in the income statement, or the pro forma effect on net income and earnings per
share of such compensation expense to be disclosed in the notes to the Company's
consolidated financial statements commencing with the Company's 1996 fiscal
year. The Company expects to adopt SFAS No. 123 on a disclosure basis only. As
such, implementation of SFAS No. 123 is not expected to impact the Company's
consolidated financial statements.

In March 1995, Statement of Financial Accounting Standards No. 121,
"Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to
be Disposed Of " ("SFAS No. 121"), was issued. This Statement establishes
accounting standards for the impairment of long-lived assets, certain
identifiable intangibles, and goodwill related to those assets to be held and
used for long-lived assets and certain identifiable intangibles which are to be
disposed. Implementation of SFAS No. 121 is not expected to have a material
impact on the Company's consolidated financial statements.

(14) SUBSEQUENT EVENTS (UNAUDITED)

In May 1996, the Company acquired all of the outstanding capital stock of
Response Healthcare Information Management, Inc. ("Response") for approximately
$6,200,000 in cash. Response specializes in capturing and analyzing
point-of-care, patient-centered data relating to disease-specific outcomes
measurement, member/patient satisfaction and functional status, as well as the
development of Internet applications. Response's primary customers include
managed care organizations and pharmaceutical companies. At the date of the
acquisition, the Company recorded a non-recurring charge of $4,372,000 relating
to acquired in-process research and development costs.

On July 19, 1996, the Company entered into a definitive agreement to
acquire LBA Health Care Management, Inc. ("LBA") through the acquisition of all
of the capital stock of its parent company, HealthVISION, Inc., for
approximately $130,000,000, $100,000,000 of which is payable in cash and
$30,000,000 of which is payable through delivery of 492,960 shares of common
stock of the Company. The Company has obtained a commitment from a bank for a
$100,000,000 credit facility to fund the cash portion of the purchase price,
which the Company intends to repay with the net proceeds of an offering of its
common stock soon after the date of acquisition. LBA is a provider of health
care information products and services that combine data collection,
benchmarking and decision support tools to identify and quantify cost reduction
and quality improvement opportunities in clinical settings.

DECEMBER 31, 1995 AND 1994

1. THE COMPANY, ORGANIZATION AND BASIS OF PRESENTATION

acquired substantially all of the business, assets, and liabilities of LBA
Health Care Management, Inc. and Healthcare Data Source (collectively, the
"Predecessor Business") pursuant to the terms of the Purchase Agreement dated

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

REVENUE RECOGNITION

Revenue is recognized ratably over the estimated time to complete a
contract which is six to twelve months in duration.

The Company has offered Value Enhancement systems to health care providers
throughout the United States. As part of the Value Enhancement Programs, the
Company has guaranteed that each customer will achieve cost savings. In the
event such cost savings are not achieved, the Company may be subject to claims
related to such guarantees. The Company or its predecessor did not incur any
such claims during the periods ended December 31, 1993, 1994 and 1995. No
reserves are maintained for any potential future claims.

ACCOUNTS RECEIVABLE

Receivable balances represent amounts due primarily from hospitals in the
United States for consulting work performed. The Company performs ongoing credit
evaluations of these companies and generally does not require collateral.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES -- Continued
UNBILLED RECEIVABLES

Unbilled receivables represent recoverable costs and accrued profit related
to contracts on which revenue has been recognized, but billings have not been
presented to the customer.

INTANGIBLES

Intangibles reflect the allocation of excess purchase price resulting from
the acquisition of the Predecessor Business. Amortization is based upon the
periods of expected economic benefit which are as follows: goodwill -- 20 years,
covenants-not-to-compete -- 3 years, value enhancements -- 2.5 years,
backlog -- 1 year, and assembled workforce -- 3 years.

Acquired technology which is in process, has not reached technological
feasibility, and has no alternative future use is written-off in the period in
which it is acquired. The write-off of in-process technology was $1,580,000 for
the period September 28, 1995 through December 31, 1995.

Intangibles consist of the following:

========= ============
</TABLE>

Amortization has been expensed in the accompanying statements of operations
as cost of revenue of $1,911,033 and general and administrative of $2,844,839.

The Company performs evaluations as of each balance sheet date assessing
the recoverability and amortization of intangibles by determining whether the
intangibles can be recovered through the estimated undiscounted cash flows of
the businesses acquired over the remaining amortization period. The Company
considers external factors relating to each acquired business, including
technological advances, competition, regulatory developments and trends of the
businesses and other pertinent factors in making its assessment. The Company
does not believe there are currently any factors that would require an
adjustment to the carrying value of its intangibles or their remaining lives as
of December 31, 1995.

BUILDING, EQUIPMENT AND FURNITURE

Building, equipment and furniture are recorded at cost. Depreciation is
computed using the straight-line method over the estimated useful lives of the
assets which are as follows:

USE OF ESTIMATES

The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.

RECLASSIFICATIONS

Certain prior year balances have been reclassified to conform to the 1995
presentation. Additionally, retained earnings at January 1, 1993 was restated to
properly account for a prior period adjustment in the amount of $518,940.

3. INCOME TAXES

The Company accounts for income taxes in accordance with Statement of
Financial Accounting Standards No. 109 ("Statement 109"), "Accounting for Income
Taxes". Under Statement 109, the liability method is used to account for income
taxes. Under this method, deferred taxes and liabilities are determined based on
differences between the financial reporting and tax bases of assets and
liabilities and are measured using the enacted tax rates and laws that will be
in effect when the differences are expected to reverse.

The Predecessor Business elected to be classified as an S corporation under
Section 1362 of the Internal Revenue Code for federal and state income tax
purposes. Accordingly, federal income taxes on any earnings were payable by the
Predecessor Business' stockholders and not the S corporations themselves; state
income taxes were immaterial and were payable by both the Predecessor Business
and its stockholders. The provision for income taxes for the years ended
December 31, 1993 and 1994 and for the period from January 1, 1995 through
September 27, 1995 were immaterial and are not separately disclosed in the
accompanying financial statements.

Significant components of the Company's deferred tax liabilities and assets
as of December 31, 1995 are as follows:

LEGAL PROCEEDINGS

The Company is currently a defendant to a civil complaint filed April 26, 1996,
in the United States District Court of Colorado, by a former employee. The
complaint alleges that the former employee was unlawfully discharged from
the the Company. The Company believes that the suit is without merit and
intends to defend its position vigorously. While the ultimate outcome
of this lawsuit can not be determined at this time, management does not
believe that this matter will have a material adverse effect on the financial
position, cash flows or results of operations of the Company.

A current minority stockholder of HealthVISION has threatened suit in connection
with the purchase by HealthVISION in September 1995 of the assets of the
Predecessor of LBA. The outcome of this matter cannot be predicted with
certainty at this time. In connection with the distribution by HealthVISION of
its assets and liabilities not associated with LBA, the assignee of such assets
and liabilities has agreed to indemnify and hold HealthVISION, LBA and HCIA
harmless from and against any liability associated with the potential claim.
Certain current stockholders of HealthVISION have guaranteed such indemnity.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

Section 2-418 of the Maryland General Corporation Law (the "MGCL") provides
that the Registrant may indemnify any director who was, is or is threatened to
be made a named defendant or respondent to any threatened, pending or completed
action, suit or proceeding, whether civil, criminal, administrative or
investigative by reason of the fact that he is or was a director of the
Registrant, or while a director, is or was serving at the request of the
Registrant as a director, officer, partner, trustee, employee or agent of
another foreign or domestic corporation, partnership, joint venture, trust,
other enterprise or employee benefit plan, against reasonable expenses
(including attorneys' fees), judgments, penalties, fines and settlements,
actually incurred by the director in connection with such action, suit or
proceeding, unless it is established that: (i) the act or omission of the
director was material to the matter giving rise to such action, suit or
proceeding, and was committed in bad faith or was the result of active and
deliberate dishonesty; (ii) the director actually received an improper personal
benefit in money, property or services; or (iii) in the case of any criminal
proceeding, the director had reasonable cause to believe that the act or
omission was unlawful. If the action, suit or proceeding was one by or in the
right of the Registrant, no indemnification shall be made with respect to any
action, suit or proceeding in which the director shall have been adjudged to be
liable to the Registrant. A director also may not be indemnified with respect to
any action, suit or proceeding charging improper personal benefit to the
director, whether or not involving action in the director's official capacity,
in which the director is adjudged to be liable on the basis that a personal
benefit was improperly received. Unless limited by the Registrant's Charter: (i)
a court of appropriate jurisdiction, upon application of a director, may order
such indemnification as the court shall deem proper if it determines that the
director is fairly and reasonably entitled to indemnification in view of all of
the relevant circumstances, regardless of whether the director has met the
standards of conduct required by Section 2-418; and (ii) the Registrant shall
indemnify a director if such director is successful on the merits or otherwise
in defense of any action, suit or proceeding referred to above. However, with
respect to any action, suit or proceeding by or in the right of the Registrant
or in which the director was adjudged to be liable on the basis that a personal
benefit was improperly received, the Registrant may only indemnify the director
for any expenses (including, attorneys' fees) incurred in connection with such
action, suit or proceeding.

Section 2-418 of the MGCL further provides that unless limited by the
Registrant's Charter, the Registrant: (i) shall (a) indemnify an officer of the
Registrant if such officer is successful on the merits or otherwise in defense
of any action, suit or proceeding referred to above, and (b) indemnify an
officer of the Registrant if a court of appropriate jurisdiction, upon
application of an officer, shall order indemnification; (ii) may indemnify

II-1

<PAGE>
and advance expenses to an officer, employee or agent of the Registrant to the
same extent that it may indemnify directors; and (iii) may indemnify and advance
expenses to an officer, employee or agent who is not a director to such further
extent, consistent with law, as may be provided by the Charter, Bylaws, general
or specific action of the Registrant's Board of Directors or contract.

The Registrant's Bylaws provide that the Registrant shall indemnify: (i)
any individual who is a present or former director or officer of the Registrant;
or (ii) any individual who serves or has served in another corporation,
partnership, joint venture, trust, employee benefit plan or any other enterprise
as a director or officer, or as a partner or trustee of such partnership or
employee benefit plan, at the request of the Registrant and who by reason of
service in that capacity was, is or is threatened to be made a party to any
threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative, to the full extent permitted under
the MGCL. The Registrant may, with the approval of its Board of Directors,
provide such indemnification for a person who formerly served a predecessor of
the Registrant in any of the capacities described in (i) or (ii) above and for
any employee or agent of the Registrant or a predecessor of the Registrant.

The Registrant's Bylaws also provide that the reasonable expenses incurred
by a director or officer who is or is threatened to be made a party to any
threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative, shall be paid or reimbursed by the
Registrant in advance of the final disposition of the proceeding upon receipt by
the Registrant of: (i) a written affirmation by the party seeking
indemnification that he has a good faith belief that the standard of conduct
necessary for indemnification by the Registrant has been met; and (ii) a written
undertaking by or on behalf of the party seeking indemnification to repay the
amount if it shall ultimately be determined that such standard of conduct has
not been met.

The Registrant's Charter provides that, to the fullest extent permitted by
Maryland statutory or decisional law, as amended or interpreted, no director or
officer of the Registrant shall be personally liable to the Registrant or its
stockholders for monetary damages. The Registrant's Charter also provides that
except as the Bylaws of the Registrant may otherwise provide, no indemnification
shall be provided for any director or officer or for any employee or agent of
the Registrant or any predecessor of the Registrant or any other entity.

The provisions in the Charter and Bylaws do not eliminate the duty of care.
In appropriate circumstances, equitable remedies such as injunctive or other
forms of non-monetary relief remain available under Maryland law. In addition,
each director will continue to be subject to liability for breach of the
director's duty of loyalty to the Registrant or its stockholders, for acts or
omissions not in good faith or involving intentional misconduct or knowing
violations of law, for actions leading to improper personal benefit to the
director and for payment of dividends or approval of stock repurchases or
redemptions that are unlawful under the MGCL. These provisions also do not
affect a director's or officer's responsibilities under any other law, such as
the federal or state securities laws or state or federal environmental laws.

The Underwriting Agreement (a form of which is filed as Exhibit 1.1 hereto)
will provide that the Underwriters shall indemnify and hold harmless the Selling
Stockholders, the Registrant and each director, officer or controlling person of
the Registrant from and against any liability caused by any statement or
omission in the Registration Statement or Prospectus based upon certain
information furnished to the Registrant by the Underwriters for use in the
preparation thereof.

ITEM 17. UNDERTAKINGS.

Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities Act
and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Registrant of expenses
incurred or paid by a director, officer or controlling person of the Registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.

The undersigned Registrant hereby undertakes that:

1. For purposes of determining any liability under the Securities Act,
the information omitted from the form of prospectus filed as part of this
Registration Statement in reliance upon Rule 430A and contained in a form

497(h) under the Securities Act shall be deemed to be part of this
Registration Statement as of the time it was declared effective.

2. For the purpose of determining any liability under the Securities
Act, each post-effective amendment that contains a form of prospectus shall
be deemed to be a new Registration Statement relating to the securities
offered therein, and the offering of such securities at that time shall be
deemed to be the initial bona fide offering thereof.

(1) In accordance with Accounting Principle Board Opinion No. 15, any reduction
of less than 3% need not be considered dilutive. Accordingly, the
consolidated statements of operations reflect net income (loss) per share
and the weighted average number of shares used in the calculation on a
primary basis only.

(2) As of March 31, 1996, options to purchase 698,558 shares of common stock
were outstanding. In the calculation of primary net income per share, these
options were included in the average number of common shares outstanding
using the treasury stock method based on the average price of the common
stock for the period.

(3) As the price of the Company's common stock as of March 31, 1996 was less
than the average price for the three month period ended March 31, 1996, the
fully diluted earnings per share calculation for the three month period is
not applicable.
