Finding care in Arizona

### Davis-Monthan AFB Healthcare Active duty airmen stationed at Davis-Monthan AFB are typically enrolled in TRICARE Prime and receive primary care at the **355th Medical Group**. Family members may also be seen on-base on a space-available basis, or they may be referred to civilian providers in the Tucson network.

### Using the Provider Directory To find civilian doctors, specialists, or urgent care centers in Tucson, Phoenix, or Sierra Vista, you must use the **TriWest Healthcare Alliance** provider directory. * **Network Providers:** These doctors have an agreement with TriWest to provide care at established 2026 rates and will file claims for you. * **Non-Network Providers:** These providers do not have a contract with TriWest. You will likely pay higher cost-shares and may have to file your own claims.

### Telehealth in Arizona Telehealth services are widely available through TriWest and Express Scripts for mental health and minor medical issues. Arizona residents can often access "Doctor on Demand" or similar platforms with a referral if using Prime, or without one if using TRICARE Select.

Common questions for Arizona beneficiaries

**I am PCSing to Davis-Monthan AFB. When should I switch my enrollment?** You should update your address in DEERS as soon as you arrive. Because Arizona is in the West Region, if you are coming from an East Region state (like Florida or North Carolina), you must specifically transfer your enrollment to TriWest Healthcare Alliance.

**Can I use the Southern Arizona VA Healthcare System as a TRICARE beneficiary?** While the VA and TRICARE are separate, some TRICARE beneficiaries (particularly retirees) may use VA facilities for certain services. However, for standard TRICARE Prime or Select care, you generally use the 355th Medical Group at Davis-Monthan or a TriWest network provider.

**How does TRICARE interact with Arizona Medicaid (AHCCCS)?** By law, TRICARE is the secondary payer to most other health insurance plans, but it is the **primary** payer to Medicaid (known as AHCCCS in Arizona). If you have both, your providers must bill TRICARE first.
