## Quick answer Most TRICARE coverage for children ends at age 21, or age 23 if the child is a full-time student at an accredited college. After these limits, young adults can often purchase TRICARE Young Adult (TYA) coverage to stay insured until age 26.

Details

TRICARE follows specific federal laws regarding "aging out" of coverage. Unlike civilian plans under the Affordable Care Act, TRICARE coverage is not automatically free for adult children until age 26; it requires a transition to a premium-based plan after age 21 (or 23).

### Standard Age Limits (Age 21 vs. 23) * **Up to Age 21:** Children of eligible sponsors are covered under standard TRICARE plans (Prime or Select) as long as they are unmarried. * **Ages 21 to 23:** If the child is enrolled full-time at an approved institution of higher learning and the sponsor provides over 50% of their financial support, coverage extends to the 23rd birthday or graduation, whichever comes first.

### TRICARE Young Adult (TYA) Once a child hits the age limits above, they "age out" of regular TRICARE. However, they may qualify for TRICARE Young Adult if they are: * Unmarried. * At least 21 (or 23 if a student) but not yet 26. * Not eligible for their own employer-sponsored health plan. * Not eligible for other TRICARE coverage.

**2026 TYA Monthly Premiums (Estimated):** * **TYA Prime:** Varies by plan year — check TRICARE.mil for current rates. * **TYA Select:** Varies by plan year — check TRICARE.mil for current rates. *(Note: TYA premiums are adjusted annually by the Defense Health Agency (DHA) to reflect the actual cost of care.)*

### Incapacitated Children (No Age Limit) If a child has a permanent mental or physical disability that existed before their 21st birthday (or 23rd if a student), they may be eligible for TRICARE coverage past the normal age limits. To qualify, the child must be incapable of self-support and be dependent on the sponsor for at least 50% of their financial needs. This requires a formal "Incapacity Dependency" determination through the sponsor's uniformed service.

### Retiree and Survivor Limits * **Retirees:** The same age 21/23/26 rules apply to children of military retirees. * **Survivors:** Children of deceased service members follow the same age logic. If the spouse remarries, they lose their own coverage, but the children's eligibility generally remains unchanged until they age out.

## Who this affects * Active duty service members with children over age 18. * Military retirees with college-aged dependents. * National Guard and Reserve members (TRS/TRR). * Adult children of sponsors who are graduating college or turning 21. * Families of children with permanent disabilities.
