TRICARE Inflation & Cost Adjustments: 2026 Guide | TRICARE.com

TRICARE costs are not fixed; they are subject to annual adjustments based on economic inflation and the Cost of Living Adjustment (COLA). While your healthcare benefits remain stable, the out-of-pocket costs—such as enrollment fees, deductibles, and catastrophic caps—usually increase each January to keep pace with the rising cost of medical care.

In detail

TRICARE cost adjustments are largely driven by the annual **Cost of Living Adjustment (COLA)** determined by the Social Security Administration and the **National Health Expenditure (NHE)** projections.

### Group A vs. Group B How inflation affects you depends heavily on when you (or your sponsor) joined the military: * **Group A:** Sponsor enlisted or was appointed before January 1, 2018. * **Group B:** Sponsor enlisted or was appointed on or after January 1, 2018.

Group B beneficiaries typically see larger annual adjustments tied to the Consumer Price Index (CPI), whereas Group A retiree costs are often more stable but still subject to statutory increases.

### Key Inflation Factors for 2026 As of 2026, several areas of the TRICARE program are sensitive to inflationary pressure:

1. **Enrollment Fees (Retirees):** For TRICARE Select and TRICARE Prime, retiree enrollment fees are adjusted annually. For example, in 2026, TRICARE Select Group A retirees pay a flat annual fee, while Group B fees are calculated based on the COLA. 2. **Catastrophic Caps:** This is the maximum you pay out-of-pocket for covered services each year. These caps generally increase annually. For 2026, the cap for a Group A retiree family is significantly higher than for an active-duty family, reflecting decades of inflationary adjustments. 3. **Pharmacy Copayments:** Pharmacy costs are set by Congress and typically increase every two years to offset the rising cost of prescriptions. Under the current "T-5" contract structure managed by **Express Scripts**, mail-order and retail pharmacy copays are the primary ways inflation reaches your wallet. 4. **The T-5 Transition Impact:** With **TriWest Healthcare Alliance** taking over the West Region in 2025 and **Humana Military** managing the East, administrative costs are stabilized by long-term contracts, but the "allowable charge" for providers rises with inflation.

### 2026 Cost Trends (Examples) | Cost Category | Impact of Inflation | 2026 Status | | :--- | :--- | :--- | | **Active Duty Premiums** | None | Always $0 | | **Retiree Prime Enrollment** | Moderate | Increased via COLA % | | **Prescription Drugs** | High | Fixed hikes by Congress | | **Out-of-Network CARE** | High | Subject to "allowable charge" gaps |

Who this applies to

* **Retirees and their Families:** Most affected. Annual enrollment fees and catastrophic caps increase based on the previous year's inflation data. * **Active Duty Family Members (ADFMs):** Minimally affected for Prime users; Select users may see slight increases in deductibles if they are in Group B. * **TRICARE Reserve Select (TRS) / Retired Reserve (TRR) / Young Adult (TYA):** These members pay "full-cost" premiums. Because these premiums are recalculated annually based on the actual cost of providing care, they are highly sensitive to medical inflation. * **Providers:** Doctors in the TriWest (West) and Humana (East) networks receive payments based on the CHAMPUS Maximum Allowable Charge (CMAC), which is adjusted for inflation annually.

Common scenarios

**Scenario 1: The Group B Retiree** John retired in 2022 (Group B). Because of 2025 inflation, his TRICARE Select enrollment fees rose for 2026. Instead of the ~4% increase he saw last year, his family's annual enrollment fee and catastrophic cap adjusted upward by the 2026 COLA percentage, adding roughly $30–$50 to his annual fixed costs.

**Scenario 2: The TRS Member** Sarah is a member of the Selected Reserve using TRICARE Reserve Select. Because the Defense Health Agency (DHA) saw an 8% increase in the cost of claims due to medical inflation, her monthly premium for 2026 increased to reflect the actual cost of the program, as TRS premiums are not subsidized by the government in the same way Prime is.

**Scenario 3: Pharmacy Costs** An ADFM filling a brand-name maintenance medication at a retail pharmacy might notice the copay increased from $38 to $43 (hypothetical 2026 rates) following a Congressional budget adjustment designed to keep pace with pharmaceutical price inflation.
