                         IDX SYSTEMS CORPORATION REPORTS
                           2004 SECOND QUARTER RESULTS

         Strong Revenues Fueled by Domestic and International Growth

    BURLINGTON, Vt., July 29 -- IDX Systems Corporation (Nasdaq: IDXC) reported
results today for the second quarter ended June 30, 2004.

    Revenues for the second quarter ended June 30, 2004 increased to $130.4
million compared with $98.3 million for the second quarter of 2003. Revenues for
the six-month period ended June 30, 2004 increased to $232.9 million compared
with revenues of $190.7 million for the same period in 2003.

    Net income from continuing operations for the second quarter 2004 was $8.1
million, or $0.26 per diluted share, compared with net income from continuing
operations of $5.4 million, or $0.18 per diluted share, in the same period last
year.

    For the six-month period ended June 30, 2004, IDX reported net income from
continuing operations of $9.7 million, or $0.31 per diluted share, compared with
net income from continuing operations of $9.1 million, or $0.31 per diluted
share, in the same period last year.

    As previously projected, 2004 results reflect startup costs associated with
the company's business in the United Kingdom.

    "Revenues were strong in the quarter, fueled by international and domestic
growth. We believe our broad domain expertise, based on 35 years of working with
prestigious healthcare organizations, coupled with our advanced technologies,
position us for accelerated growth in the global healthcare environment," said
James H. Crook Jr., Chief Executive Officer of IDX. "We signed agreements that
represent expanded partnerships with existing customers and generated
significant new business grounded in our vision of making a difference in
healthcare."

    MOMENTUM CONTINUES ACROSS IDX BUSINESS LINES

    Separately today, IDX announced the following noteworthy contracts signed in
the second quarter.

    New agreements for IDX Flowcast(TM) included Metropolitan Health Plan (MHP),
of Hennepin County, MN, a health maintenance organization that serves a
seven-county region. MHP has utilized the IDX managed care application for more
than 10 years. IDX alliance partner Allscripts Healthcare Solutions was selected
as MHP's clinical solution. Additionally, Drexel University Physicians(TM), the
physician's group of the Drexel Univeristy College of Medicine, of Philadelphia,
PA selected IDX Flowcast 3.0. The 320-provider physician group also selected
Allscripts as its electronic medical record solution.

    The selection of Flowcast 3.0 will enable improvements for these
organizations in two key areas: follow-up on unpaid claims and reduced days in
accounts receivable. Flowcast and Allscripts will provide a comprehensive,
integrated solution for practice management and clinical automation and
strengthen financial and administrative support.

    IDX Groupcast(TM) agreements in the second quarter spanned small to mid-
size group practices including billing services, single-specialty practices and
complex, multi-site groups including Mercy Clinic, of Joplin, MO, a 79- doctor,
25-location medical group, which supports St. John's Regional Medical Center.

    IDX also signed an agreement to upgrade North Carolina Baptist Hospital of
Winston-Salem, NC to the advanced technology of IDX Carecast(TM). The 830-bed
healthcare facility has been an IDX customer since 1996 and is the major
teaching hospital for Wake Forest University Baptist Medical Center. The
organization intends to continue its comprehensive use of electronic patient
records, introduce electronic tools for interdisciplinary care planning and
expand CPOE across inpatient and ambulatory settings. As a result of this
planned expansion, approximately 600 physicians will be able to submit
medication orders online from the clinic setting to North Carolina Baptist
Hospital.

    IDX Imagecast(TM) agreements include long-time customer Inova Health System
of Falls Church, VA, a multi-hospital system that conducts 600,000 radiology
exams annually, for the IDX Radiology Information System (RIS) and Picture
Archiving and Communications System (PACS).

    Imagecast RIS customer, Temple University Health System of Philadelphia, PA
purchased the PACS for full-fidelity image distribution across its five-hospital
enterprise. The agreement is one of the three largest PACS deals signed by IDX.

    IDX management remains comfortable with projected 2004 revenue guidance of
$500 - $525 million and earnings per share guidance of $0.95 - $0.99. The
company projects 2005 revenues of $600 - $650 million and earnings per share
guidance of $1.20 - $1.35.

    A conference call with investors will be held on July 29, 2004 at 11:00 am
EDT to discuss these results. An audio Webcast of the call will be available at
our Internet site: http://www.idx.com, Investor Relations, Multimedia.
