TriWest is the United States Department of Defense's contractor for management of the TRICARE health entitlement program available to active duty military members, their families, retirees and retirees' families. When health care cannot be provided at a military installation, TriWest connects families with an extensive network of more than 95,000 community physicians, hospitals and other health care providers. These individuals are eligible for the DoD's regionally managed health care program for the military, called TRICARE. TriWest is under contract with the DoD to manage and administer TRICARE throughout the 21-state TRICARE West Region. In addition to supporting military families through the TRICARE program, TriWest has developed relationships with organizations such as the USO, Fisher House, the Women in Military Service for America Memorial Foundation and other military relief and support associations to strengthen America's military community locally and nationally.
