## Definition The claims filing deadline is the strict timeframe—typically one year from the date of service or discharge—within which a claim must be submitted to TRICARE to be eligible for payment.

## What it means in practice For most TRICARE beneficiaries in the United States and U.S. territories, the claims filing deadline is **one year from the date you received medical care** or one year from the date of discharge for an inpatient hospital stay. If you miss this window, TRICARE is legally prohibited from paying the claim, and you may be held responsible for the entire bill.

In most cases, you won't have to worry about this deadline because network providers are contractually required to file claims on your behalf. However, if you see a non-network provider, receive care overseas, or have Other Health Insurance (OHI) where you must file manually after the primary payer processes the claim, the clock starts ticking the moment the service occurs. For 2026, the TRICARE regional contractors—**Humana Military** in the East and **TriWest Healthcare Alliance** in the West—strictly enforce these windows.

If you are filing a claim for care received overseas, the deadline is more generous: you generally have **three years** from the date of service to submit your claim to **International SOS**. Regardless of the location, if a claim is denied because it was filed late, you cannot appeal the denial unless you can prove "extraordinary circumstances" prevented the timely filing (such as a mental or physical disability that made filing impossible).

It is also important to note the interaction with Other Health Insurance. If your primary insurance takes several months to process a claim, you must still ensure the secondary TRICARE claim reaches the contractor within the one-year limit. Waiting for a primary insurer is not typically considered a valid excuse for missing the TRICARE filing deadline.
