## Quick answer TRICARE refunds typically occur when you have overpaid a deductible, paid out-of-pocket for a covered service that was later authorized, or were billed a copayment that exceeded your Catastrophic Cap. Most refunds are issued automatically by the regional contractor (Humana Military or TriWest) or Express Scripts, but you must manually file a claim within one year of service for retroactive reimbursements.

## In detail Refunds in the TRICARE system generally fall into three categories: overpayments, retroactive eligibility, and pharmacy adjustments. Because TRICARE is a "second payer" to most other health insurance (OHI), many refunds are triggered when OHI pays a claim after you already paid a provider.

### 1. Medical Claims Overpayment If you pay a provider directly and then TRICARE pays that same provider, the provider is legally required to refund your overpayment. If you paid the regional contractor (Humana Military or TriWest) for enrollment fees or premiums in advance and later switched to a plan with no fees (like moving from Select to Prime while on Active Duty), you are entitled to a prorated refund of those premiums.

### 2. The Catastrophic Cap Refund Once you reach your annual Catastrophic Cap (the maximum amount you pay out-of-pocket for covered services in a calendar year), TRICARE pays 100% of the allowed amount for the rest of the year. * **2026 Caps:** For Group A Active Duty Families, the cap is $1,000. For Group B Retirees on TRICARE Select, the cap in 2026 can exceed $4,000 depending on specific status. * **How it works:** If you encounter a lag in processing and pay a $30 copay after you already hit your cap, the contractor's system should flag this and mail a check automatically.

### 3. Pharmacy Refunds Pharmacy refunds are handled through Express Scripts. This usually happens if: * You paid full price for a prescription because your eligibility wasn't updated in DEERS. * You paid for a brand-name drug when a generic was available, but a medical necessity waiver was later approved.

### 4. Direct Care (MTF) Refunds If you are asked to pay a fee at a Military Treatment Facility (MTF) and it is later determined you shouldn't have, the refund is processed through the specific facility's Uniform Business Office (UBO).

## Who this applies to * **Retirees and Families:** Most likely to see refunds regarding enrollment fees or exceeding the Catastrophic Cap. * **Active Duty Families (Select):** Often see refunds when Other Health Insurance (OHI) coordinates after a TRICARE claim is processed. * **TRICARE Reserve Select (TRS) / Retired Reserve (TRR) Members:** Frequently deal with premium refunds when transitioning back to active service. * **Young Adult (TYA) Members:** May receive refunds for months of coverage paid in advance if they gain employer-sponsored coverage.

Common scenarios

### The "Double Payment" Jane, a TRICARE Select beneficiary in the East Region, has a $160 visit in February 2026. She pays the provider $160 upfront. The provider later bills Humana Military, which pays the provider the "allowable amount" of $110. The provider now has $270 for a $110 service. Jane must request a $160 refund from the provider, as they are not allowed to keep more than the TRICARE-negotiated rate.

### The Catastrophic Cap Overrun Mark, a retiree, hits his $4,000 catastrophic cap in October 2026. In November, he visits a specialist and pays a $50 copay by mistake. Because the regional contractor (TriWest in the West) tracks the cap automatically, Mark receives a check for $50 in the mail three weeks later without filing a form.

### The DEERS Lag Sarah fills a $70 prescription while her DEERS status is temporarily "inactive" during a transition. She pays the full cash price. Two weeks later, after her DEERS record is fixed, she submits a claim to Express Scripts. She is refunded the $70 minus her standard 2026 copayment (e.g., $16 for a brand-name formulary drug).

## Related terms * **Catastrophic Cap:** The maximum out-of-pocket limit you pay each year for TRICARE-covered services. * **Allowable Charge:** The maximum amount TRICARE will pay for a specific medical service. * **DEERS:** The Defense Enrollment Eligibility Reporting System; if this is wrong, your "refund" can't be processed. * **Explanation of Benefits (EOB):** The document showing what TRICARE paid and what you owe; essential for proving overpayment. * **T-5 Contract:** The current TRICARE contract (effective 2025) which transitioned West Region management to TriWest.
