TRICARE Montana: Plans, Providers, and TriWest Guide | TRICARE.com

TRICARE in Montana

Montana is part of the **TRICARE West Region**. Since January 1, 2025, the West Region contractor has been **TriWest Healthcare Alliance**, which replaced Health Net Federal Services (HNFS). While Montana is a geographically massive state with many rural areas, beneficiaries have access to a robust network of civilian providers and the 341st Medical Group at Malmstrom Air Force Base.

Major military installations

Montana is primarily home to the Air Force and the Montana National Guard. While there are fewer large-scale installations than in coastal states, the following are the primary hubs for military activity:

* **Malmstrom Air Force Base** – Great Falls (Air Force Global Strike Command) * **Fort Harrison** – Helena (Montana National Guard Headquarters) * **Maelstrom-Great Falls International Airport** – Great Falls (Montana Air National Guard / 120th Airlift Wing)

Plans available in Montana

Montana residents have access to several TRICARE plans depending on their status (Active Duty, Guard/Reserve, or Retiree). As of 2026, the primary options include:

| Plan | Best For... | | :--- | :--- | | **TRICARE Prime** | Active duty members and their families living near Malmstrom AFB. Includes **Prime Remote** for those in rural "frontier" areas far from a base. | | **TRICARE Select** | Those who want to manage their own specialty care without referrals; requires meeting a deductible and paying copays. | | **TRICARE Reserve Select (TRS)** | Qualified members of the Selected Reserve and their families. | | **TRICARE Retired Reserve (TRR)** | Retired Reserve members under age 60 and their families. | | **TRICARE For Life (TFL)** | Dual-eligible beneficiaries (TRICARE and Medicare) focused on wraparound coverage. | | **TRICARE Young Adult** | Adult children (up to age 26) who have aged out of regular TRICARE coverage. |

*Note: The US Family Health Plan (USFHP) is **not** available in Montana.*

Finding care in Montana

Because Montana is such a rural state, finding "network" providers can be challenging outside of Great Falls, Billings, Missoula, and Helena.

1. **Provider Directory:** Use the [TriWest Provider Directory](https://www.triwest.com) to find local civilian doctors, hospitals, and specialists who accept the 2026 TRICARE rates. 2. **Network vs. Non-Network:** In rural Montana, you may find "non-network" providers who are "TRICARE-authorized." If you use a non-network provider, you may have to pay higher out-of-pocket costs and file your own claims. 3. **Telehealth:** Given the distances required for travel in the Big Sky Country, TRICARE’s telehealth benefit is highly utilized in Montana. 2026 rates for telehealth follow the same cost-shares as in-person office visits. 4. **Pharmacy:** Most beneficiaries use the **Express Scripts** mail-order service for maintenance medications to avoid long drives to retail pharmacies.

Common questions for Montana beneficiaries

**How does TRICARE work if I live in a rural area like Libby or Glendive?** You will likely qualify for **TRICARE Prime Remote**. This plan allows you to receive primary care from local civilian providers without a military hospital nearby. You will still need a Primary Care Manager (PCM) to coordinate your care.

**I am moving to Montana from the East Region (Humana Military). What do I do?** Since Montana is in the West Region managed by **TriWest Healthcare Alliance**, you must update your address in DEERS and contact TriWest to transfer your enrollment. Your coverage does not "move" automatically between regions.

**Does Montana Medicaid (Healthy Montana Kids) work with TRICARE?** Yes. By law, TRICARE is the primary payer and Medicaid is the payer of last resort. If you are eligible for both, the provider must bill TRICARE first.
