## Quick answer TRICARE provides permanent medical coverage for adult children over age 21 (or 23 if a full-time student) if they have a severe physical or mental disability that occurred before their eligibility originally expired. To maintain coverage, the child must be incapable of self-support, and the sponsor must provide more than 50% of their financial maintenance.

Details

### Eligibility Criteria For an adult child to qualify for "Disabled Adult Child" (DAC) status under TRICARE—commonly referred to as an Incapacitated Dependent—the following conditions must be met: * **Onset of Disability:** The disabling condition must have occurred before the child's 21st birthday (or before the 23rd birthday if they were a full-time student at the time of onset). * **Incapability of Self-Support:** The child must be unable to support themselves through gainful employment due to the disability. * **Financial Dependency:** The sponsor must provide more than 50% of the child's financial support. * **Marital Status:** The child must remain unmarried. If a disabled adult child marries, TRICARE eligibility ends and cannot be reinstated, even if the marriage later ends.

### The Determination Process Eligibility is not automatic. The sponsor must apply for a "Medical Sufficiency Statement" or "Incapacity Determination" through their branch of service’s personnel office (not through TRICARE directly). 1. **Medical Evaluation:** A physician must provide a statement detailing the diagnosis, date of onset, and how the condition prevents self-support. 2. **Financial Assessment:** The Dependency Claims office of the sponsor's service branch will review income and expenses to verify the 50% support requirement. 3. **DEERS Update:** Once the service branch approves the incapacity, the child's status is updated in the Defense Enrollment Eligibility Reporting System (DEERS).

### Costs and Plan Options Once the adult child is certified as an incapacitated dependent in DEERS, they are eligible for the same TRICARE plans as other family members. In 2026, costs depend on the sponsor's status: * **Active Duty Families:** Generally no enrollment fees for TRICARE Prime. * **Retiree Families:** Subject to annual enrollment fees (e.g., TRICARE Select or Prime) based on the sponsor's "Group" (Group A or B based on initial enlistment date). * **Medicare Interaction:** If the disabled adult child becomes eligible for Medicare Part A and B (often after receiving Social Security Disability Insurance for 24 months), they must transition to **TRICARE For Life (TFL)** to remain covered by TRICARE. They must have Medicare Part B to keep TFL.

### Periodic Re-certification Incapacity status is rarely "permanent" in the eyes of the military. Depending on the condition, the service branch may require a medical and financial re-evaluation every 1 to 5 years to ensure the child still meets the criteria for self-support and dependency.

## Who this affects * **Active Duty Service Members:** With adult children who have lifelong disabilities (e.g., Down Syndrome, severe Autism, or cerebral palsy). * **Retirees:** Maintaining coverage for adult children after the sponsor leaves active duty. * **Survivors:** Eligible surviving children of deceased sponsors can maintain coverage if the incapacity was established. * **National Guard and Reserve:** Beneficiaries under TRICARE Reserve Select (TRS) or TRICARE Retired Reserve (TRR) who meet the same dependency criteria.
