NEWPORT BEACH, Calif. – May 26, 2005 – The TriZetto Group Inc. (NASDAQ: TZIX) announced that Preferred Care Partners has become the 21st Medicare Advantage health plan to purchase its Facets® administrative system. Facets is now used to process medical transactions for approximately 15 percent of the managed Medicare market. The customer will also deploy several of TriZetto's specialized software components, including NetworX Pricer™, NetworX Modeler™, Facets e2 Workflow and the HealthWeb® eService Internet platform.

"At Preferred Care Partners, our IT strategy includes a commitment to state-of-the-art technology, fundamental to providing affordable coverage and quality health care for our members," said Roger Rodriguez, vice president of Care Management for Preferred Care Partners.

According to Tony Bellomo, executive vice president of TriZetto's software unit, the government's recent reform of Medicare has increased the number of commercial health plans serving Medicare beneficiaries. However, this market opportunity also imposes significant demands upon these organizations.

"Health plans that want to compete effectively in the Medicare space will need the right software and IT services to address requirements such as the new Part D drug benefit coverage," said Bellomo. "In addition, the government now requires Medicare Advantage plans to offer disease management programs to members who have chronic illnesses. To stay competitive, these plans will need to operate more efficiently while at the same time deliver richer benefits to members. TriZetto's Facets platform and broad technology solutions can drive this administrative efficiency, while supporting Medicare Part D, quality care, and improved network management."
