FOR IMMEDIATE RELEASE


                         IDX SYSTEMS CORPORATION REPORTS
                           FIRST QUARTER 1999 RESULTS


BURLINGTON,  VT, April 21, 1999--IDX Systems Corporation (Nasdaq: IDXC) reported
financial results today for the first quarter ended March 31, 1999.

Revenue in the first quarter was $60.2  million,  compared with $72.7 million in
the first quarter of last year. The company reported a first quarter net loss of
($6.9) million or ($0.26) per share, compared with net income of $4.4 million or
$0.16 per share in the same quarter last year.

"As we announced on March 5, 1999, our first quarter financial results are below
expectation  due to the  unexpected  deferral  of  purchasing  decisions  by our
customers and prospects," said Richard E. Tarrant,  Chief Executive Officer. "We
believe that our business is fundamentally sound and that the performance of our
core  business  (excluding  Internet  initiatives)  will  improve  as  the  year
progresses.  We anticipate  reporting  positive net income in the second quarter
and increasing the  profitability of our core business during the balance of the
year. We expect our Internet tracking division,  IDX.com,  to lose approximately
$9.0 million pretax in 1999, which will result in a pretax loss of approximately
$7.0 million for the Company overall.
Revenue for the year is expected to reach approximately $310 million."

"It is difficult to fully estimate the impact of deferred  purchasing  decisions
on our financial results in 2000," Mr. Tarrant continued. "Given the information
currently available, we expect to grow revenue by 15-20% in 2000 and to increase
net income  substantially in our core business.  Once our customers have reached
the other side of Y2K computer problems,  we may see an increase in sales orders
that would help offset the longer sales cycle.  We also plan to continue to keep
a tight rein on discretionary spending during the year. "

As part of its Internet strategy,  the Company reported that it purchased 80% of
ChannelHealth,  Inc.  on  April  1,  1999.  ChannelHealth,   based  in  Bedford,
Massachusetts,  develops Internet services that provide consumers with extensive
health-related information and the ability to purchase medical products on-line.
IDX paid $6.5 million in cash for its ownership  interest in ChannelHealth,  and
may pay an additional $3.0 million, contingent upon certain performance goals. A
substantial  portion of the projected loss for the IDX.com tracking  division in
1999 is attributable to ChannelHealth.

"We believe the  successful  healthcare  information  technology  company of the
future will combine software expertise with Internet  capabilities," Mr. Tarrant
said. "Given our established  customer base,  comprehensive system solutions and
our investments in Internet  products and services,  IDX has solidly defined its
position as a leader in the industry."

Founded  in  1969,  IDX  Systems   Corporation   provides  complete   healthcare
information   solutions  for  integrated   delivery  networks   including  group
practices,  MSOs,  health plans,  and  hospitals.  To connect  systems and sites
across the enterprise,  IDX offers the IDXtendR @ the Site  Series--products and

This material contains forward-looking statements that involve a number of risks
and  uncertainties.  Among the important factors that could cause actual results
to differ materially from those indicated by such forward-looking statements are
the possible  deferral,  delay or  cancellation  by customers of computer system
purchase  decisions,  variations  in the volume and timing of systems  sales and
installations, timing and quality of development and implementation of year 2000
ready solutions for customers, the potential disruption of customers' purchasing
plans  due  to  work  on  their  own  year  2000   problems,   development   and
implementation  of year 2000 ready  products  for the  Company's  internal  use,
possible  delay,  varying  lengths of sales cycles and  installation  processes,
seasonal  patterns  of sales  and  customer  buying  behaviors,  development  by
competitors  of  new  or  superior  technologies,  possible  delays  in  product
development, undetected errors or bugs in software, potential product liability,
changing  economic,  political  and  regulatory  influences  on  the  healthcare
industry,  changes in  product  pricing  policies,  possible  regulation  of the
Company's  software by the U.S. Food and Drug  Administration,  general economic
conditions,  and the risk factors  detailed  from time to time in the  Company's
periodic  reports and  registration  statements  filed with the  Securities  and
Exchange  Commission,   which  important  factors  are  incorporated  herein  by
reference.
