Overseas Pharmacy Claims
How TFL beneficiaries fill prescriptions outside the US — usually pay up front and file for reimbursement.
Also known as: overseas Rx, TRICARE Overseas Pharmacy
Quick answer
Outside the United States, the TRICARE retail network does not operate. TFL beneficiaries pay overseas pharmacies up front and submit a paper claim (DD Form 2642) to Express Scripts for reimbursement at TRICARE-allowable rates. TRICARE Home Delivery can still ship to APO/FPO/DPO addresses; commercial overseas addresses generally cannot receive Home Delivery shipments.
Why it matters
Pharmacy access overseas is dramatically different from the US — no network, no electronic adjudication. Planning ahead (using Home Delivery to APO/FPO, stockpiling routine refills before travel) prevents surprises.
Why this matters at age 65
Retirees who travel internationally or live abroad must understand that overseas pharmacy reimbursement is partial and slow. Plan 90-day buffer supplies before extended overseas travel.
When you'll encounter it
International travel, retirement abroad, or stationed-overseas adult dependents on TFL.
Impact on Medicare
Medicare generally does NOT cover overseas care or prescriptions. TRICARE Pharmacy continues as the only meaningful drug coverage overseas.
Impact on TRICARE For Life
TFL/TRICARE Pharmacy is the primary drug benefit overseas. Pay up front, file DD 2642 within one year, expect partial reimbursement at TRICARE rates.
Impact on Medicare Advantage
Most MA plans provide little to no overseas coverage. TRICARE Pharmacy is essential for any overseas retiree.
Military-specific context
Mail or upload DD Form 2642 with itemized receipts to Express Scripts. Translation of foreign-language receipts may be required. Allow 6–8 weeks for processing.
Common misconceptions
- "TRICARE Home Delivery ships anywhere." — Only to US, APO/FPO/DPO addresses. Commercial foreign addresses cannot receive Home Delivery.
Common mistakes to avoid
- Discarding overseas pharmacy receipts.
- Waiting until the last week of the 1-year filing window to submit DD 2642.
- Assuming Medicare will reimburse overseas pharmacy bills — it won't.
Real-world scenario: A retiree wintering in Portugal needs a 90-day blood-pressure refill.
He pays out of pocket at a Lisbon pharmacy (~€60), keeps the itemized receipt, files DD 2642 within the year, and is reimbursed at the TRICARE-allowable rate (~$40 equivalent).
What should I do?
- 1Order a 90-day Home Delivery refill before leaving the US.
- 2If filling overseas, get an itemized receipt with the drug name, strength, quantity, and date.
- 3File DD Form 2642 with Express Scripts within one year — sooner is better.
- 4If based at APO/FPO/DPO, keep using Home Delivery — it's the same as stateside.

- Medical NecessityA documented clinical justification that a non-formulary or restricted drug is required — allowing TRICARE to cover it at a lower tier.
- Pharmacy Prior AuthorizationA pre-approval requirement Express Scripts imposes on certain drugs before TRICARE Pharmacy will pay.
- WPS (TFL Claims Contractor)Wisconsin Physicians Service — the Defense Health Agency contractor that processes TRICARE For Life secondary claims.
- Brand-Name DrugsFDA-approved drugs sold under a manufacturer's proprietary name — middle copay tier on the TRICARE formulary.
- Coordination of Benefits (COB)The federal and contractual rules that determine which insurer pays first when you have more than one health plan.
- Creditable Drug CoveragePrescription drug coverage that CMS certifies is at least as good as standard Medicare Part D — including TRICARE Pharmacy and VA Pharmacy.
- Express ScriptsThe pharmacy benefit manager that administers the TRICARE Pharmacy Program, including TFL home-delivery and retail-network prescriptions.
- Who pays first, Medicare or TRICARE For Life?Medicare pays first for any service it covers. TFL pays second. The claim usually crosses over automatically — you should never pay out of pocket up front.
- Should I enroll in Medicare Part D?No, for almost every TFL beneficiary. TRICARE Pharmacy (Express Scripts) is creditable coverage and cheaper than most Part D plans. Adding Part D usually costs more without adding benefit.
- Is there an enrollment fee for TRICARE For Life?No. TFL has no enrollment fee and no monthly premium. The only premium you pay is for Medicare Part B.
- Should I enroll in a Medicare Advantage plan that includes Part D (MAPD)?Only if the MA plan otherwise makes sense for you. The Part D piece duplicates TRICARE Pharmacy — but you keep TRICARE Pharmacy as a fallback. Don't enroll just for the drug coverage.
- Does TFL cover long-term care or a nursing home?No. Medicare and TFL only cover short-term skilled care after a qualifying hospital stay. Custodial long-term care (assisted living, nursing home for daily living help) isn't covered by either.
