Mil: Official TRICARE Health Resources Guide
## Quick answer In the context of military healthcare, "**Mil**" typically refers to **TRICARE.mil**, the official Department of Defense website for the TRICARE health program. It serves as the primary gateway for service members and their families to manage benefits, find providers, and view the most current policies for civilian-provided medical care.

In detail
When navigating "mil" resources for healthcare, beneficiaries are usually interacting with the **Defense Health Agency (DHA)**. As of June 2026, the TRICARE system is divided into two primary domestic regions, each managed by a specific contractor under the T-5 contract.
### Official Regional Portals The "mil" ecosystem connects you to specific contractors based on your location: * **TRICARE East:** Managed by **Humana Military**. * **TRICARE West:** Managed by **TriWest Healthcare Alliance** (which assumed control on Jan 1, 2025). * **Overseas:** Managed by **International SOS**.
### Key 2026 Plan Categories The military health system categorizes beneficiaries into "Groups" which determine their out-of-pocket costs at civilian "mil" providers: * **Group A:** Sponsor’s initial enlistment or appointment was before Jan. 1, 2018. * **Group B:** Sponsor’s initial enlistment or appointment was on or after Jan. 1, 2018.
### 2026 Cost Examples (Select Plans) Depending on your "mil" status (Active Duty vs. Retiree), your costs for 2026 vary:
| Service Type | TRICARE Select (Retiree/Group A) | TRICARE Prime (Retiree/Group A) | | :--- | :--- | :--- | | **Annual Enrollment Fee** | ~$380 family (2026 rate) | ~$750 family (2026 rate) | | **Primary Care Visit** | ~$38 (In-network) | $0 (With referral) | | **Specialty Care Visit** | ~$53 (In-network) | $0 (With referral) | | **Emergency Room** | ~$165 (In-network) | ~$85 |
### The Pharmacy Layer All "mil" health plans utilize **Express Scripts** as the Pharmacy Benefit Manager. Whether you use military pharmacies (MTFs), home delivery, or retail, your records are integrated into the central DEERS (Defense Enrollment Eligibility Reporting System) database.
Who this applies to
* **Active Duty Service Members (ADSMs):** Must use TRICARE Prime; all care is managed through military clinics or referred "mil" network providers. * **Active Duty Family Members (ADFMs):** Can choose between Prime (lower cost, less flexibility) or Select (higher cost, more flexibility). * **Retirees and their Families:** Subject to annual enrollment fees and cost-shares at civilian providers. * **National Guard/Reserve:** Eligible for TRICARE Reserve Select (TRS) while in a qualified non-activated status.
Common scenarios
1. **The New Enlistee (Group B):** A soldier joins in 2026. Their spouse uses TRICARE Select. Because they are Group B, they face a 2026 enrollment fee and a higher deductible (varies by year) compared to Group A members before they reach the catastrophic cap. 2. **The West Region Transition:** A family in California needs a specialist in June 2026. Because **TriWest Healthcare Alliance** took over the West region in 2025, the family must ensure their "mil" referral is processed through the TriWest portal, not the previous contractor (HNFS). 3. **Retired Specialist Visit:** A retired Navy commander (Group A) in Virginia (East Region) visits a civilian dermatologist. Under TRICARE Select in 2026, they pay a fixed copayment (e.g., ~$53) rather than a percentage, provided the doctor is an "In-Network" provider found via the Humana Military directory.
