## Quick answer In most cases, if you see a network provider, you don't have to file a claim; the provider does it for you. You only need to file a claim manually if you see a non-network provider, receive care overseas, or if a pharmacy claim isn't processed at the point of sale. Claims must typically be filed within one year of the date of service in the U.S. or three years for overseas care.

In detail

Managing TRICARE claims effectively requires understanding who is responsible for the paperwork. TRICARE divided its administrative tasks by region: **Humana Military** manages the East Region, **TriWest Healthcare Alliance** manages the West Region (as of 2025), and **Express Scripts** handles pharmacy claims.

### Who files the claim? * **Network Providers:** They are contractually required to file claims for you. You only pay your cost-share or copayment at the time of service. * **Non-Network Providers:** You may have to pay the full bill upfront and file **DD Form 2642** (Patient’s Request for Medical Payment) yourself to be reimbursed. * **Overseas:** You almost always pay upfront and file a claim with **International SOS**, unless you are an active duty service member receiving authorized care.

### Submission Deadlines (2026 Policy) Missing a deadline is the most common reason for claim denial. * **United States and U.S. Territories:** Claims must be received within **one year** of the date of service or the date of hospital discharge. * **Overseas:** Claims must be received within **three years** of the date of service.

### Required Documentation When filing manually, you must include: 1. **DD Form 2642**: The standard claim form. 2. **Itemized Bill**: Must include the provider’s name, address, Tax ID or NPI, date of service, CPT codes (procedure codes), and ICD-10 codes (diagnosis codes). 3. **Proof of Payment**: If you paid the provider in full. 4. **Other Health Insurance (OHI) EOB**: If you have a private plan (like through a civilian employer), TRICARE is the secondary payer. You must file with your OHI first and include their Explanation of Benefits (EOB) with your TRICARE claim.

Claim Processing Comparison (2026)

## Who this applies to * **TRICARE Select Beneficiaries:** Frequently see non-network providers and are more likely to need to file manual claims. * **TRICARE Prime Beneficiaries:** Rarely file claims unless they seek emergency care at a non-network facility or use the Point-of-Service (POS) option. * **Active Duty Service Members (ADSMs):** Usually have claims handled automatically through MTFs or authorized referrals; however, emergency civilian care may require follow-up. * **TRICARE For Life (TFL) Users:** Medicare is the primary payer. Medicare usually "crosses over" the claim to TRICARE automatically, but manual filing is required if care is received overseas (where Medicare does not pay).

Common scenarios

**The Out-of-Network Specialist** Jane is on TRICARE Select in the West Region. She visits a non-network specialist who charges $300 for a consultation. The provider does not file TRICARE claims. Jane pays $300 upfront. She submits DD Form 2642 to **TriWest**. Once her 2026 deductible is met, TRICARE reimburses her the allowable charge minus her 20% cost-share.

**The Overseas ER Visit** Mark, a retiree living in Italy, goes to a local hospital for an emergency. He pays $1,200 out of pocket. He submits his claim to **International SOS** with a translated itemized bill. Because it is overseas care, he has three years to file, though he does so immediately to recover his funds.

**The Pharmacy Mishap** Sarah tries to fill a prescription at a retail pharmacy, but the system shows she has Other Health Insurance (OHI) that has since expired. She pays the full $95 retail price. To get reimbursed, she must file a claim with **Express Scripts** providing the receipt and proof that the other insurance is closed.

## Related terms * **Explanation of Benefits (EOB):** A statement sent by the contractor explaining what was covered, what was denied, and what the patient owes. * **Allowable Charge:** The maximum amount TRICARE will pay for a specific medical service. * **DD Form 2642:** The official "Patient's Request for Medical Payment" form used for manual medical claims. * **Point-of-Service (POS) Option:** A feature of TRICARE Prime that allows patients to see non-network providers without a referral, typically resulting in higher out-of-pocket costs and manual claims. * **Other Health Insurance (OHI):** Any non-TRICARE health insurance you have (except Medicaid). TRICARE pays last after OHI.
