## Quick answer TRICARE defines "Family Coverage" as any plan that covers at least two family members (typically a spouse and children). Once you have two or more enrolled family members under one sponsor, you pay a single flat "family" rate for premiums and reach your catastrophic cap much faster than if individuals were billed separately.

Details

In the TRICARE system, you do not pay per child. There are only two enrollment categories for premiums and enrollment fees: **Individual** and **Family**.

### The "Family" Enrollment Rule If you are an Active Duty family, your coverage remains $0 for premiums. However, for those in premium-based plans (like TRICARE Reserve Select or TRICARE Retired Reserve) or retirees paying enrollment fees (TRICARE Select Group A/B), the "Family" rate applies whether you have a spouse and one child or a spouse and ten children.

### 2026 TRICARE Reserve Select (TRS) Rates For National Guard and Reserve members, the monthly premiums for 2026 are: * **Member Only:** Varies by plan year — check TRICARE.mil for current rates. * **Member and Family:** Varies by plan year — check TRICARE.mil for current rates.

### The Catastrophic Cap Family coverage is most beneficial regarding the **catastrophic cap**, which is the maximum amount you pay out-of-pocket for covered services each year. * **Individual Cap:** Applies only to the individual’s expenses. * **Family Cap:** Once the combined out-of-pocket costs for all family members reach this limit, TRICARE pays 100% of the allowable charge for the remainder of the calendar year. * For 2026, the cap for Active Duty Families is $1,000 (Group A/B). For Retirees in TRICARE Select, it is significantly higher (varies by group status).

### Adding Family Members (QLEs) You cannot add family members at any time. You must have a **Qualifying Life Event (QLE)**, such as: 1. **Marriage:** Add a new spouse within 90 days. 2. **Birth or Adoption:** Register the child in DEERS immediately. You have 90 days (120 days if overseas) to enroll them in a specific plan. 3. **Divorce:** A former spouse may lose eligibility unless they meet specific "20/20/20" rule criteria.

### Contractor Boundaries Coverage for your family is managed by the regional contractor where the family resides: * **East Region:** Humana Military. * **West Region:** TriWest Healthcare Alliance (effective Jan 1, 2025). * **Pharmacy:** Express Scripts.

## Who this affects * **Active Duty Families:** No premiums; uses "Family" catastrophic caps. * **Retirees:** Pay fixed "Family" enrollment fees for Select or Prime. * **Guard/Reserve:** Pay "Member + Family" premiums for TRS or TRR. * **Survivors:** Eligible for family coverage at specific rates depending on the sponsor's status at the time of death.
