## Quick answer Most TRICARE beneficiaries never have to file a claim; if you see a TRICARE-authorized provider, they will file the paperwork for you. You only need to manually file a claim (using DD Form 2642) if you see a non-participating provider, receive care overseas, or utilize a pharmacy that does not coordinate with Express Scripts.

In detail

TRICARE claims are the formal requests for payment sent to the regional contractors—**Humana Military** (East), **TriWest Healthcare Alliance** (West), or **International SOS** (Overseas).

### Who Files the Claim? * **In-Network/Participating Providers:** These doctors are contractually obligated to file claims on your behalf. You only pay your specific copayment or cost-share at the time of service. * **Non-Participating Providers:** You may have to pay the full bill upfront and then file a claim with TRICARE to be reimbursed. * **Pharmacy:** Most claims are handled electronically by **Express Scripts**. However, if you use a non-network pharmacy, you must file a manual claim for reimbursement.

### Filing Timelines (2026 Deadlines) The deadline for filing a claim depends on where the service was rendered: * **United States and U.S. Territories:** Claims must be filed within **one year** of the date of service or the date of an inpatient discharge. * **Overseas:** Claims must be filed within **three years** of the date of service.

### Required Documentation If you are filing manually, you must include: 1. **DD Form 2642:** The Patient’s Request for Medical Payment. 2. **Itemized Bill:** Must include the provider's name, address, tax ID, date of service, procedure codes (CPT/HCPCS), and diagnosis codes (ICD-10). 3. **Proof of Payment:** Required for reimbursement claims. 4. **Other Health Insurance (OHI) Explanation of Benefits (EOB):** If you have other insurance, TRICARE is almost always the secondary payer and requires the EOB from your primary insurer before they will process the claim.

### Where to File | Region | Contractor | Submission Method | | :--- | :--- | :--- | | **East** | Humana Military | Online Portal or Mail (P.O. Box 7031, Camden, SC) | | **West** | TriWest | Online Portal or Mail (P.O. Box 202106, Florence, SC) | | **Overseas** | International SOS | TRICARE Overseas Secure Claims Personal Portal | | **Pharmacy** | Express Scripts | Online via Express Scripts site or Mail |

## Who this applies to * **TRICARE Prime:** Rarely need to file claims unless they receive emergency care from a non-authorized provider and the provider refuses to bill. * **TRICARE Select:** May need to file claims if using "non-participating" providers who do not accept "assignment" (direct payment from TRICARE). * **TRICARE For Life (TFL):** Medicare usually files the claim automatically with TRICARE. TFL users only file manually if Medicare does not cover the service but TRICARE does. * **Overseas Beneficiaries:** Frequently file manual claims, as many international doctors require cash payment upfront.

Common scenarios

### Scenario 1: The Out-of-Network Specialist (2026) John is on TRICARE Select. He visits a non-participating specialist for a consultation costing $300. Because the doctor does not work with TRICARE, John pays $300 out of pocket. He submits DD Form 2642 to TriWest (West Region). TRICARE's "allowable charge" for this visit is $200. After his 2026 deductible is met, TRICARE pays 80% of the allowable charge ($160) back to John.

### Scenario 2: Emergency Overseas Sarah is traveling in Germany and has an emergency appendectomy costing €5,000. She pays the hospital via credit card. She must submit her itemized, translated receipt and DD Form 2642 to International SOS. They will convert the currency and reimburse her based on the TRICARE allowable rate for that region.

### Scenario 3: Secondary Payer (OHI) Mary has employer-sponsored insurance and TRICARE through her retired spouse. She goes to a doctor who bills her primary insurance $500. The primary insurance pays $350. Mary must wait for the Explanation of Benefits (EOB) from her employer's plan, then mail that EOB plus the claim form to Humana Military for TRICARE to cover the remaining $150 balance.

## Related terms * **Explanation of Benefits (EOB):** A statement sent by the contractor explaining what was covered, what was paid, and what the patient owes. * **Allowable Charge:** The maximum amount TRICARE will pay for a specific medical service. * **DD Form 2642:** The official form used by beneficiaries to submit a claim for medical services. * **Other Health Insurance (OHI):** Any non-TRICARE health insurance you have; TRICARE pays second after OHI. * **Point-of-Service (POS) Option:** A feature of Prime that allows users to see non-network providers, often resulting in higher out-of-pocket costs and the need to file claims.
