TRICARE Dependent Coverage Guide: Spouses & Children 2026
*TRICARE.Com is an independent reference site and is not the official TRICARE program. For official policy, please visit TRICARE.mil.*
## Quick answer TRICARE dependent coverage provides health insurance for the spouses and children of military service members, including active duty, retirees, and Guard/Reserve. Children are generally covered up to age 21 (or 23 if enrolled in college), though they may extend coverage through age 26 via the TRICARE Young Adult program.
Details
### Who qualifies as a dependent? Under TRICARE, eligible dependents typically include: * **Spouses:** Lawfully married partners (including same-sex spouses). * **Children:** Biological, adopted, stepchildren, and certain court-ordered wards. * **Survivors:** Spouses and children of deceased service members. * **Dependent Parents:** In specific cases, parents or parents-in-law may be eligible for care in Military Treatment Facilities (MTFs) only, on a space-available basis.
### Age limits and the "21/23" Rule Standard dependent coverage ends when a child turns **21**. However, it can be extended until age **23** if the child is a full-time student at an approved institution of higher learning and the sponsor provides at least 50% of their financial support.
If a child is older than 21/23 and has a permanent disability that occurred while they were eligible for coverage, they may qualify for "Incapcitated Dependent" status, which provides lifelong coverage.
### TRICARE Young Adult (TYA) If a child ages out of standard coverage but remains unmarried and is not eligible for their own employer-sponsored health plan, they can purchase TRICARE Young Adult until age 26. * **2026 TYA Prime Monthly Premium:** varies by plan year — check TRICARE.mil for current rates. * **2026 TYA Select Monthly Premium:** varies by plan year — check TRICARE.mil for current rates.
### Plan Options for Dependents Dependents typically choose between two main paths based on their location and preference for flexibility: 1. **TRICARE Prime:** A managed care option similar to an HMO. Active duty family members pay $0 in premiums and $0 for most care as long as they use a Primary Care Manager (PCM). 2. **TRICARE Select:** A PPO-style plan. It offers more freedom to choose doctors but involves annual deductibles and cost-shares (copays).
### Costs for 2026 * **Active Duty Family Members (ADFMs):** No enrollment fees for Prime or Select. * **Retiree Family Members:** Both Prime and Select require annual enrollment fees. For Group A retirees in 2026, the family enrollment fee is approximately $770–$800 for Prime and $380–$410 for Select (check TRICARE.mil for final 2026 adjustments). * **Pharmacy:** Managed by Express Scripts. Most dependents pay $0 for generic drugs at military pharmacies, while retail and home delivery carry tiered copays ($18–$83 depending on the drug type in 2026).
## Who this affects * **Active Duty Spouses and Children:** Most comprehensive coverage with lowest out-of-pocket costs. * **Retirees and their Families:** Includes those in the East (Humana Military) and West (TriWest). * **National Guard and Reserve:** Dependents of members on TRICARE Reserve Select. * **Survivors:** Widows/widowers and children of deceased service members.
