4102 Pinion DriveYou're in the TRICARE West Region, run by TriWest Healthcare Alliance. Their directory is the only list that reflects who is actually in network today — network status changes on contract cycles, so a list published anywhere else (including here) would go stale between visits.
Contractors and directory links verified against tricare.mil's provider directory list and its regional contractor page on August 1, 2026.
Being listed here does not mean a facility can take you as a patient. Military hospitals and clinics serve active duty service members first, and most set their own rules about which other beneficiaries they can enroll based on space available. If you are enrolled in TRICARE Prime, your primary care manager (PCM) assignment decides where you are seen. Call the number on the facility above before you go, and see how the plans differ if you are not sure which one you have.
