[Medford, Oregon – January, 2023] PLEXIS Healthcare Systems, a leading healthcare payer technology company, is proud to announce it will support the contract awarded to TriWest Healthcare Alliance to administer the U.S. Department of Defense’s (DoD) next generation TRICARE program, known as “T-5,” for its 26-state West Region territory. TRICARE is the uniformed services health care program for active-duty service members, active-duty family members, National Guard and Reserve members and their family members, retirees and retiree family members, survivors, and certain former spouses. T-5 is designed to improve the delivery, quality, and cost of health care services for service members, retirees, and their families.

As part of the close partnership with TriWest, PLEXIS will provide its next generation core administrative processing solution Quantum Choice, augmented by its flexible data integration layer, facilitating efficient real time system-to-system integration and automation. Quantum Choice effectively sets the foundation for significant componentization, interoperability, and scalability to meet the challenges of integrated healthcare delivery and significant membership growth within the TRICARE T-5 West Region program.

“We are privileged to work alongside the TriWest team as they serve our nation’s heroes and their family members under the TRICARE program,” said Jose Lopez, Senior VP of Business Development for PLEXIS Healthcare Systems. “It is an honor to support the critical work of TriWest as they continue to focus on enhancing the experience of care and great health care outcomes for our nation’s active-duty service members, National Guard and reservists, retirees and their family members.”
