Coverage Details
Choose a country to see detailed information about Medicare coverage options, restrictions, and important notes for seniors.
When it comes to international health care, U.S. Medicare is a federal health insurance program for people 65 or older, certain younger disabled individuals, and people with End-Stage Renal Disease. Many seniors wonder if they can use this coverage while traveling or receiving treatment abroad. The short answer: a few countries have formal agreements or emergency‑only provisions that let you tap Medicare benefits outside the United States.
Key Takeaways
- Only a handful of nations provide any Medicare coverage beyond emergency care.
- Coverage type varies: emergency‑only, limited elective procedures, or full inpatient care.
- Eligibility hinges on the U.S. Medicare program rules set by the Centers for Medicare & Medicaid Services.
- Proper documentation and advance authorization are essential to avoid denied claims.
- Planning ahead can save seniors thousands of dollars and reduce travel stress.
How Medicare Determines Foreign Coverage
Centers for Medicare & Medicaid Services (CMS) governs what services are reimbursable abroad. CMS follows three core principles:
- Emergency medical treatment is covered when an enrollee is in a foreign country and needs immediate care that cannot wait for a return to the U.S.
- Elective or scheduled procedures are generally not covered unless the patient lives abroad full‑time and meets specific residency criteria.
- Any care provided must be at a facility that meets the same Medicare-certified standards as U.S. hospitals.
These rules are the same for Original Medicare (Part A and Part B) and for Medicare Advantage plans, though private insurers may offer additional benefits in certain countries.
Countries that Accept Medicare - What They Offer
| Country | Coverage Type | Typical Restrictions | Notes for Seniors |
|---|---|---|---|
| Canada | Emergency only | Must be nearest U.S. hospital if feasible; no elective surgery | Use provincial health system for follow‑up care; keep original claim forms |
| Mexico | Emergency only (border hospitals) & limited elective under some Medicare Advantage plans | Hospitals must be Medicare‑certified; pre‑authorization required for electives | Popular for dental and orthopedic procedures in private clinics |
| Bahamas | Emergency only | Only tertiary care centers recognized by CMS | Ideal for short‑term vacation medical trips |
| France | Limited elective for U.S. citizens residing long‑term (via bilateral agreements) | Proof of residency > 90 days; must enroll in French social security | High‑quality cardiac and oncology centers accepted |
| Australia | Emergency only | Only public hospitals; private clinics excluded | Travel insurance recommended for gaps |
| New Zealand | Emergency only | Same as Australia; limited to acute trauma | Ideal for adventure travel injuries |
| Singapore | Elective under some Medicare Advantage plans (rare) | High out‑of‑pocket costs; requires private insurer partnership | World‑class cardiac surgery; verify plan details first |
| United Kingdom | Emergency only (via NHS agreements) | Must be on an Emergency Care Travel Scheme; no elective | Use NHS Emergency Departments; keep receipts for Medicare claim |
Notice that most countries only cover emergencies. If you need elective procedures, you’ll usually have to rely on private insurance or pay out‑of‑pocket and later submit a claim for potential partial reimbursement.
Step‑by‑Step: Using Medicare Abroad
- Confirm your enrollment status: Make sure you have Part A (hospital) and Part B (medical) coverage active.
- Check the country’s specific Medicare rules: Visit the CMS website or call the Medicare hotline (1‑800‑MEDICARE).
- Obtain a Medicare card copy and a letter of medical necessity if traveling for planned care.
- Identify a Medicare‑certified facility abroad: Use the CMS “International Provider Directory” or ask your home doctor for referrals.
- Secure pre‑authorization for any elective procedure (if your plan permits).
- Travel with original claim forms, receipts, and discharge summaries in English.
- File the claim with Medicare within 60 days of discharge using the standard CMS claim packet.
Skipping any of these steps can lead to claim denial, which means you’ll bear the full cost.
Common Pitfalls and How to Avoid Them
- Assuming coverage: Many seniors think Medicare works like private travel insurance. It does not - only emergencies are guaranteed.
- Missing documentation: Without a detailed discharge summary, Medicare can’t verify the service.
- Choosing non‑certified hospitals: Facilities that don’t meet U.S. standards are automatically excluded.
- Ignoring residency rules: Some countries require you to be a resident for a minimum period before any coverage applies.
- Overlooking out‑of‑pocket caps: Even when a claim is accepted, you may still be responsible for 20% of the approved amount.
Planning Tips for Seniors Going Abroad
Before you book that medical‑tourism trip, consider these practical actions:
- Buy a supplemental travel health plan that fills the gaps where Medicare stops.
- Consult a Medicare‑savvy travel agent or a clinic that specializes in international patients.
- Keep a digital copy of your Medicare card, insurance cards, and a list of your current medications.
- Learn the local emergency number (e.g., 999 in the UK, 112 in EU).
- Check if the destination country participates in the World Health Organization “International Health Regulations” - this often aligns with higher hospital standards.
Future Outlook: Changes Expected in 2026
CMS is piloting a “Global Medicare Access” program that could expand coverage to more OECD nations. Watch for announcements in early 2026, especially regarding:
- Formal bilateral agreements with Spain and Portugal.
- Expanded elective coverage for Medicare Advantage plans in the Caribbean.
- Online claim submission portals for faster reimbursement.
Staying informed will help seniors make the most of their benefits when traveling.
Does Medicare cover routine doctor visits abroad?
No. Routine or preventive visits are not covered unless you are a permanent resident of the foreign country and the provider is Medicare‑certified.
Can I use my Medigap plan overseas?
Most Medigap policies only supplement U.S. Medicare for services rendered in the United States. Some carriers offer limited foreign‑incidence riders, but they are rare and usually expensive.
What paperwork do I need after an emergency abroad?
Collect the original discharge summary, itemized bill, proof of payment, and a completed CMS claim form (CMS‑149). Submit them within 60 days to avoid denial.
Are there any countries where Medicare covers elective surgery?
Only a few, such as France (for long‑term residents) and selected Caribbean nations under specific Medicare Advantage contracts. Always verify with your plan before scheduling.
How does travel insurance interact with Medicare?
Travel insurance can cover out‑of‑pocket costs, non‑covered services, and evacuation. It does not replace Medicare but fills the gaps where Medicare stops.
