Beneficiaries in Arizona, particularly those near major hubs like Luke AFB, benefit from a robust network of civilian and military providers.

## Major military installations Arizona is home to several critical military installations across multiple branches:

* **Luke Air Force Base (AFB):** Glendale (Maricopa County) - Air Force * **Davis-Monthan Air Force Base:** Tucson - Air Force * **Fort Huachuca:** Sierra Vista - Army * **Marine Corps Air Station (MCAS) Yuma:** Yuma - Marine Corps * **Yuma Proving Ground:** Yuma - Army * **Camp Navajo (National Guard):** Belmont - Army National Guard

## Plans available in Arizona Beneficiaries in Arizona have access to the following 2026 TRICARE plans, depending on their eligibility status:

| Plan Name | Best For | Note | | :--- | :--- | :--- | | **TRICARE Prime** | Active Duty & Families near bases | Managed care; requires enrollment at Luke AFB or Davis-Monthan if in a Prime Service Area. | | **TRICARE Select** | Those wanting flexibility | PPO-style plan; allows any network provider without a referral. | | **TRICARE Reserve Select** | National Guard/Reserve | Premium-based plan for qualified members of the Selected Reserve. | | **TRICARE Retired Reserve** | Retired National Guard/Reserve | For retired reserve members under age 60. | | **TRICARE For Life** | Medicare-eligible retirees | Wraparound coverage for those with Medicare Part A & B. | | **TRICARE Young Adult** | Adult children (18–26) | Available in Prime or Select versions for those who aged out of regular coverage. |

## Finding care in Arizona For those living near **Luke AFB**, primary care is often provided at the 56th Medical Group on base. However, if you are using TRICARE Select or are a Prime enrollee referred to the civilian network, you must use the **TriWest Healthcare Alliance** provider directory to find network doctors in Glendale, Phoenix, or Tucson.

* **Network Providers:** Choosing a network provider in Arizona ensures lower out-of-pocket costs and no need to file your own claims. * **Non-Network Providers:** You may pay higher "point-of-service" fees if you see a non-network provider without a referral. * **Telehealth:** Arizona beneficiaries can access 24/7 care through the Military Health System Nurse Advice Line or utilize telehealth services approved by TriWest. Express Scripts also handles all pharmacy benefits for Arizona residents.

Common questions for Arizona beneficiaries

**I am PCSing to Luke AFB; what do I do?** You should contact TriWest Healthcare Alliance as soon as you arrive to update your address and enrollment. If you are on TRICARE Prime, you will likely be empaneled at the 56th Medical Group at Luke AFB.

**Does TRICARE work with AHCCCS (Arizona Medicaid)?** Yes, but TRICARE is always the secondary payer to Medicaid. If you are eligible for the Arizona Health Care Cost Containment System (AHCCCS), federal law requires TRICARE to pay last.

**What is the "T-5" shift in Arizona?** The T-5 contract started on January 1, 2025. It moved Arizona and the rest of the West Region to TriWest Healthcare Alliance. If you have been in Arizona since 2024, your provider information and authorizations should have migrated, but you should verify your "Moving" status in DEERS to ensure no gaps in coverage.
