The TriZetto Group Inc. (NASDAQ: TZIX) announced today that Indiana University Health, a physician-owned organization with 45,000 Medicaid members, has selected QNXT? as it's core administration system.

Indiana University Health, which does business as the IU Medical Group-Primary Care, selected QNXT for its exceptional flexibility. ?To succeed in today's marketplace, organizations need to be able to respond quickly to new business opportunities as they are emerging,? said Celia Surface-Bruder, chief financial officer. ?The flexibility, configurability and user-friendly interface will allow us to meet that challenge.? In addition to its Medicaid membership, the organization contracts with various Catholic-owned entities to administer their Family Planning benefits to more than 200,000 members.

?This new contract reflects the continuing momentum among payers for the QNXT administration platform, especially those payers preferring .NET technology,? said Rob Scavo, president of Core Administration Solutions at TriZetto. ?Since completing the acquisition of QCSI in January, TriZetto has generated more than $40 million in QNXT-related software, maintenance and consulting contract bookings, including a 100% license renewal rate.?
