IDX SYSTEMS CORPORATION REPORTS

2004 FIRST QUARTER RESULTS

Customer momentum across business lines drives continued growth

BURLINGTON, VT – April 29, 2004 – IDX Systems Corporation (NASDAQ:IDXC) reported results today for the first quarter ended March 31, 2004.

Revenues for the first quarter 2004 increased to $102.6 million compared to $92.4 million in the first quarter of 2003.

IDX reported first quarter 2004 net income of $1.6 million, or $0.05 per fully diluted share, compared to 2003 net income of $3.8 million, or $0.13 per fully diluted share. As previously projected, first quarter 2004 results reflect startup costs associated with the company’s business in the United Kingdom. IDX expects the UK business to be accretive to earnings beginning this year.

“We began 2004 firmly established in the global marketplace, and our results for the first quarter clearly show our sustained momentum domestically, as we continue to execute against our plan across the company,” said James H. Crook Jr., Chief Executive Officer of IDX. “Our partnership approach to our customer relationships, coupled with robust and proven solutions, continues to spur new growth.”

Significant Momentum Across IDX Business Lines

Separately today, IDX announced additional noteworthy contracts signed in the first quarter, reflecting significant momentum across all business lines.

New agreements for Flowcast^™ included Creighton Medical Associates, an academic multi-specialty group practice operating as a division of Creighton University School of Medicine in Omaha, Nebraska. The IDX solution will automate key processes in the revenue cycle for 225 faculty members located in Creighton University’s primary affiliated teaching hospital (Creighton University Medical Center) and eight community-based primary care clinics. Currently, 75 percent of academic medical centers utilize IDX solutions.

Additionally, Brown & Toland Medical Group, San Francisco, CA, will upgrade to Flowcast 3.0, IDX’s next-generation business performance solution, including the TouchWorks^™ EMR (electronic medical record) solution from Allscripts Healthcare Solutions (NASDAQ: MDRX), an alliance partner of IDX. Flowcast and TouchWorks will provide a complete, integrated solution for practice management and clinical automation and strengthen financial and administrative support for 315 primary care physicians and 1,200 specialists.

IDX expanded an agreement with Vancouver Health Authority, the largest academic health authority in Canada, for the IDX Carecast^™ Patient Accounting solution. Carecast will enable integrated clinical and financial capabilities in six facilities serving 75 percent of the comprehensive health system, encompassing 1,800 beds. The agreement will also allow VCH to deploy Carecast patient accounting functionality across its eight acute care hospitals and numerous outpatient facilities.

Groupcast^™ enjoyed a strong new account performance with small to mid-size group practices including billing services, single-specialty practices and complex, multi-site groups, demonstrating the flexibility and broad applicability of our solution.

Imagecast^™ agreements were signed with long-time customer Wellspan Health Systems, who will pioneer a new cardiology offering, and UC Davis, the fourth of five prestigious University of California teaching hospitals that utilize Imagecast.

A long-time Imagecast Radiology Information System (RIS) customer, Wellspan Health will upgrade its IDX RIS and purchased the full IDX Picture Archiving and Communications System. Wellspan Health includes York Hospital and Gettysburg Hospital (total of 630 beds) and 31 ambulatory care and outpatient sites.

UC Davis Health System will use Imagecast RIS to drive workflow and clinical improvement throughout their health system, which conducts more than 800,000 patient visits each year.

IDX remains comfortable with projected 2004 revenue of $500 - $525 million and earnings per share guidance of $0.95 - $0.99.

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