TRICARE Young Adult (TYA) Guide: 2026 Costs & Rules

TRICARE Young Adult (TYA) is a premium-based plan that allows adult children of military sponsors to maintain health coverage after their regular dependent benefits expire at age 21 (or 23 if a full-time student). It provides coverage up to age 26 for those who are not married and not eligible for their own employer-sponsored health insurance.

In detail

TRICARE Young Adult was created to align with the Patient Protection and Affordable Care Act (ACA), ensuring that military children have access to coverage until age 26. However, unlike civilian plans where parents can often add children to their employer plan at little to no extra cost, TYA requires a monthly premium.

### Plan Options Qualified beneficiaries can choose between two versions of TYA, depending on where they live and their sponsor's status:

* **TYA Prime:** Functions like TRICARE Prime. You have a Primary Care Manager (PCM) and need referrals for specialty care. This is generally available in Prime Service Areas (PSAs) in the East and West regions. * **TYA Select:** Functions like TRICARE Select. You have more flexibility to choose your own doctors and do not need referrals, but you will face higher out-of-pocket costs and deductibles.

### 2026 Monthly Premiums Because TYA is a premium-based program, the costs are adjusted annually based on the actual cost of providing care. For the 2026 plan year, the rates are:

*Rates are per individual. If a family has two children enrolled in TYA, they must pay two separate premiums.*

### Eligibility Requirements To qualify for TYA, the young adult must meet all of the following criteria: 1. Be an unmarried biological, adopted, or stepchild of an eligible TRICARE sponsor. 2. Be at least age 21 (or age 23 if a full-time student) but not yet age 26. 3. Not be eligible for their own employer-sponsored health insurance plan. 4. Not be eligible for any other TRICARE program in their own right (e.g., through their own military service).

### Regional Management * **East Region:** Managed by **Humana Military**. * **West Region:** Managed by **TriWest Healthcare Alliance** (as of the T-5 contract transition). * **Pharmacy:** All TYA participants receive pharmacy coverage through **Express Scripts**.

## Who this applies to * **Adult Children (Ages 21–26):** Specifically those who have aged out of standard TRICARE but have not yet reached their 26th birthday. * **Active Duty Families:** Children of active duty members who need a bridge until they find career-based insurance. * **Retiree Families:** Children of retired service members who are still within the age limit. * **Full-time Students:** Students who reach age 23 and lose their regular TRICARE coverage while still in school.

Common scenarios

### Scenario 1: The Recent College Graduate Sarah is 22, unmarried, and just graduated from college. Her father is a retired Navy Captain. Because she graduated, her regular TRICARE coverage ended. She has a part-time job that does not offer health insurance. She enrolls in **TYA Select** for the 2026 rate of **$337/month** so she can continue seeing her preferred local doctor.

### Scenario 2: The Unemployed 24-Year-Old Marcus is 24 and living in a Prime Service Area near a military base. His mother is Active Duty Army. Marcus is currently looking for work and does not have insurance. He chooses **TYA Prime** to keep his out-of-pocket costs low for office visits, paying the 2026 premium of **$655/month**.

### Scenario 3: Losing Eligibility Elena is 25 and enrolled in TYA Select. She gets married in June. On the day she marries, she is no longer eligible for TYA. She must notify her regional contractor (Humana Military or TriWest) to terminate her coverage, as she no longer meets the "unmarried" requirement.
