Reminder: New TRICARE Regional Contracts in the U.S. in 2025
TriWest Healthcare Alliance will replace the current West Region contractor, Health Net Federal Services, LLC, in 2025. While there will still be two TRICARE regions, six states currently in the East Region (Arkansas, Illinois, Louisiana, Oklahoma, Texas, Wisconsin) will move to the West Region. There are also some zip codes in four of these states that will be exceptions to the region changes.
