Can medicare be used overseas?
If you’re traveling outside the U.S., it’s important to understand whether Medicare will cover your medical expenses abroad. In most cases, Medicare offers very limited coverage overseas, and you’ll likely need additional travel health insurance to be fully protected.
Quick Definition
Medicare generally does not cover medical care outside the U.S., but there are rare exceptions for emergency treatment in certain situations — and some Medigap plans provide limited foreign travel coverage.
What Medicare Usually Does Not Cover Abroad
Routine medical care when you’re outside the U.S. is almost always not covered by Original Medicare.
Prescription drug coverage under Medicare Part D does not extend to medications bought in a foreign country.
Foreign hospitals typically do not bill Medicare directly — you may need to pay upfront and submit your own itemized bills for possible reimbursement.
Limited Exceptions When Medicare Might Cover You Outside the U.S.
There are a few very specific situations when Medicare may pay for medical services received in a foreign hospital:
Emergency Near the Border
If you have a medical emergency while in the U.S. and the closest hospital that can treat you is actually in a foreign country, Medicare may cover that hospitalization.
This also applies if you live in the U.S. and the nearest hospital is across the border in Canada or another country.
Travel Through Canada
If you’re traveling by “the most direct route” through Canada (for example, between Alaska and another U.S. state) and you have an emergency, Medicare may pay for care in a Canadian hospital — but only if there’s no U.S. hospital closer.
Cruise Ship Within U.S. Waters
Medicare may cover doctor or ambulance services while you’re on a cruise ship, but only if the ship is within U.S. territorial waters.
Once the ship is more than six hours away from a U.S. port, coverage typically ends.
Role of Medigap (Supplemental) Insurance
Certain Medigap plans (supplemental Medicare policies) do provide emergency medical coverage abroad.
These Medigap plans may pay a large portion of your Medicare-approved costs for emergency care while traveling.
However, there is often a lifetime limit on how much foreign travel coverage you can use under Medigap.
Medicare Advantage (Part C) and International Travel
Most Medicare Advantage plans do not cover routine care outside the U.S.
Some Advantage plans may cover emergency care abroad, but the amount and limits vary greatly — you must check your plan’s summary of benefits.
What You Should Do Before Traveling Abroad on Medicare
Review Your Medicare Plan
Confirm with Medicare or your plan about what services (if any) are covered outside the U.S.Check Your Medigap Policy
If you have a Medigap plan, find out if it includes “foreign travel emergency” coverage and what its limits are.Consider Travel Health Insurance
Since Medicare coverage abroad is very limited, a travel medical insurance policy may give you better protection for emergencies.Plan for Prescription Needs
Don’t count on Medicare Part D when abroad — your plan won’t cover prescriptions purchased in most foreign countries.Keep Records
If you’re covered, make sure to get itemized hospital or doctor bills for any care overseas so you can file them for reimbursement if possible.
FAQ
Q1: Will Medicare pay for a hospital stay abroad?
Only in rare emergency situations — for example, if the foreign hospital is closer than a U.S. hospital.
Q2: Are there Medicare plans that cover me when I’m traveling?
Yes, some Medigap plans cover emergency care abroad, but there are limits and deductibles.
Q3: Does Medicare cover prescriptions I buy outside the U.S.?
No. Part D does not pay for outpatient medications purchased overseas.
Q4: Can I rely on Medicare when I retire abroad?
No — Medicare usually does not cover routine or long-term care abroad, so you’ll need additional coverage or local insurance.
Q5: What if I’m on a cruise ship?
Medicare may cover doctor or ambulance services only when the ship is in U.S. territorial waters (close to U.S. ports).
Final Summary
Medicare is not built for international travel — it generally will not pay for medical care outside of the U.S. Except in very rare cases, you’ll need to rely on supplemental insurance (Medigap) or a separate travel health insurance plan to protect against medical emergencies when traveling abroad.
