Effective January 1, 2025, TriWest Healthcare Alliance is the TRICARE West regional contractor, replacing Health Net Federal Services as the administrator.
Stanford Health Care is in-network for hospital services.
TriWest Healthcare Alliance is also the third-party administrator for the Department of Veterans Affairs (VA) Community Care Network (CCN) programs. Veterans traditionally receive care through the VA’s network of medical facilities but there are times when the VA turns to community providers to provide services for their veterans.
Stanford Health Care Tri-Valley Hospital is in-network with TriWest Healthcare Alliance for both TRICARE and VA CCN. All services must be authorized by the VA.
