NEWPORT BEACH, Calif. - January 28, 2008 - The TriZetto Group Inc. (NASDAQ: TZIX) today announced the limited availability release of CareAdvance Medicare, for proactive care management of Medicare members. Designed to address the unique needs of senior populations and Medicare Advantage (MA) plans, CareAdvance Medicare:

• Automates case and disease management activities
• Provides case management support specific to Medicare beneficiaries
• Features a new Medicare Health Risk Assessment for seniors
• Enables MA plans to align with new guidelines of Special Needs Programs (SNPs)
• Includes identification rules that allow for improved identification and stratification of senior-specific conditions and members with chronic diseases
• Offers state-of-the-art information systems that enable adherence to CMS and NCQA standards for evidence-based algorithms, automated documentation, and comprehensive reminder systems

CareAdvance Medicare will be sold as an optional component to TriZetto's Clinical CareAdvance (CCA) application, the clinician-facing feature of the CareAdvance Enterprise (CAE) solution. Leveraging CAE's secure, Web-based platform, CareAdvance Medicare is the first solution of its kind to successfully automate the full spectrum of care management for both commercial and Medicare members.

"Health plans offering Medicare Advantage products must provide sophisticated care management programs, or they risk significant financial losses, poor quality of care, and now, regulatory scrutiny," observed Michael Cantor, MD, JD, Geriatrician and Assistant Professor of Medicine at Harvard Medical School.

CareAdvance Medicare allows payers supporting MA plans to benefit from additional care information targeted at the elderly, often managing several co-morbid conditions and a variety of age-related illnesses, such as dementia, pressure sores, frailty and more. CareAdvance Medicare also helps MA plans:

• Reduce costs by automating administrative care management workflow
• Shape members' care decisions with timely, personalized interventions
• Improve quality of care management by fostering guideline compliance
• Meet government requirements for quality initiatives and chronic-care improvements
• Satisfy members and enhance retention

"As our Medicare population in the U.S. continues to grow, so does the complexity of their care, with more patients needing regular care for chronic illnesses," said Gene Drabinski, TriZetto's president of cost and quality of care. "Increased care combined with anticipated budgetary cuts in Medicare in 2008, will necessitate increased efficiency in order to keep costs down for Medicare Advantage members. Moving forward, solutions like CareAdvance Medicare will be crucial for payers' success."

For a better understanding of CareAdvance Medicare, please attend TriZetto's launch Webinar, How to Achieve Return on Investment with Care Management of Your Senior Population, on Tuesday, January 29th, from 2:00 to 3:00pm EST. The event will be presented by Michael Cantor, MD, JD, Geriatrician and Assistant Professor of Medicine at Harvard Medical School and TriZetto's own Larry Bridge, senior vice president of Payer Markets.
