## Quick answer TRICARE dependents include the spouses and children of active duty, retired, and Guard/Reserve service members. To receive coverage, dependents must be registered in the Defense Enrollment Eligibility Reporting System (DEERS) by their sponsor and meet specific age or relationship requirements.
Details
### Who Qualifies as a TRICARE Dependent? Eligibility begins with the "Sponsor" (the service member). Once the sponsor registers a family member in DEERS, the following individuals generally qualify as dependents: * **Spouses:** Lawful husbands and wives, including same-sex spouses. * **Children:** Biological, adopted, step-children, and certain court-ordered wards. * **Children up to age 21:** Coverage is automatic until age 21. * **Children ages 21–23:** Coverage continues if the child is a full-time student at an approved institution and the sponsor provides over 50% of their financial support. * **TRICARE Young Adult:** Adult children may remain eligible for a premium-based plan up to age 26 if they are unmarried and not eligible for employer-sponsored health insurance. * **Dependents with Disabilities:** Children over age 21 may remain eligible if they have a severe, permanent disability that occurred before their 21st (or 23rd) birthday.
### Plan Options for Dependents Dependents do not always have the same plan as their sponsor. Their options depend on the sponsor’s status and geographic location:
1. **TRICARE Prime:** Available in Prime Service Areas. Active duty family members (ADFMs) pay $0 out-of-pocket for covered services from network providers. 2. **TRICARE Select:** A PPO-style plan available worldwide. It offers more flexibility in choosing doctors but requires annual deductibles and cost-shares. 3. **TRICARE For Life:** For dependents who are entitled to Medicare Part A and Part B, regardless of age.
### 2026 Costs and Fees Costs for dependents are categorized by the sponsor’s "Group." * **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.
For 2026, Active Duty Family Members (ADFMs) generally have **$0 enrollment fees** for Prime or Select. Retiree dependents face annual enrollment fees (e.g., for Group A Retirees in 2026, the family enrollment fee for TRICARE Prime is approximately $740–$760 per year, though users should check TRICARE.mil for the exact final 2026 inflation-adjusted figures).
### Regional Management Dependent care is managed by regional contractors: * **East Region:** Humana Military. * **West Region:** TriWest Healthcare Alliance. * **Overseas:** International SOS.
## Who this affects * **Active Duty Family Members (ADFMs):** Spouses and children of personnel on active duty. * **Retiree Family Members:** Spouses and children of retired service members. * **National Guard & Reserve Families:** Dependents of members on active duty orders or those enrolled in TRICARE Reserve Select (TRS) or TRICARE Retired Reserve (TRR). * **Survivors:** Unremarried spouses and biological/adopted children of deceased service members. * **Former Spouses:** Under the "20/20/20" or "20/20/15" rules, some former spouses may retain eligibility.
