Medicare coverage stops at the U.S. border for most situations
Original Medicare (Parts A and B) does not cover medical care you receive outside the United States, with very limited exceptions. If you travel abroad and need a doctor, hospital, or prescription filled, you will pay the full cost out of pocket — Medicare will not reimburse you. This applies to every country except Canada and Mexico, and even there the coverage is narrow.
Medicare Advantage plans (Part C) follow the same rule: they must cover the same services as Original Medicare, which means no overseas care except in those two countries under specific circumstances. Supplemental insurance (Medigap) also does not cover treatment abroad, though some Medigap plans will cover emergency care in Canada and Mexico if you are traveling there directly from the United States.
The only time Medicare pays for care outside the U.S. is if you need emergency treatment while traveling through Canada or Mexico to reach another U.S. state, or if you are a U.S. citizen living in Canada or Mexico and receive care there. Even then, the coverage is limited to emergency situations, not routine visits.
Key Takeaways
- Original Medicare and Medicare Advantage do not cover any medical care outside the United States except emergency treatment in Canada or Mexico under specific conditions.
- Medigap supplemental plans may cover emergency care in Canada and Mexico if you are traveling there directly from the U.S., but you must check your specific plan documents.
- Travel medical insurance is a separate product you purchase before leaving and can cover emergency and routine care abroad, though it has its own limits and exclusions.
- If you take a prescription medication regularly, you should carry enough for your entire trip plus extra, since Medicare will not cover refills obtained outside the U.S.
- Some countries require proof of health insurance to enter; travel insurance can satisfy that requirement where Medicare cannot.
What happens if you need emergency care while traveling abroad
If you have a medical emergency outside the U.S. and receive treatment, you will receive a bill from the foreign hospital or doctor. You can submit that bill to Medicare, but Medicare will not pay it. You are responsible for the full amount, which can be substantial — hospital costs in other developed countries are often higher than in the U.S., and you have no negotiated rate.
Some credit card companies offer limited travel medical coverage as a cardholder benefit, so check your card's terms before you leave. Travel medical insurance, purchased separately before your trip, is the only way to have overseas emergency care covered. These policies typically cover emergency hospital stays, emergency dental care, and emergency medical evacuation, but they exclude pre-existing conditions and routine care.
If you are traveling to Canada or Mexico and have a Medigap plan, review your plan documents or call the insurance company before you leave. Some Medigap plans cover emergency care in those two countries, but only if you are traveling there directly from the U.S., not if you are already abroad and happen to pass through. The coverage is usually limited to emergency situations, not scheduled appointments.
Prescription medications and refills overseas
If you take regular medications, bring enough for your entire trip plus a week's extra supply in your original labeled bottles. Do not rely on being able to refill prescriptions abroad — even if a pharmacy will fill them, Medicare will not reimburse you, and the cost can be high.
Before you leave, ask your doctor for a written prescription (not just a refill authorization) that uses the generic drug name rather than a brand name. Different countries use different brand names for the same medication, and a prescription with only the brand name may not be recognized. Keep the prescription in your carry-on bag in case your checked luggage is delayed.
Some medications that are legal and available in the U.S. are restricted or banned in other countries. Check the laws of your destination before you pack, especially if you take controlled substances like opioids or benzodiazepines. Carrying a banned medication into a country can result in arrest, even if it is legal at home.
Travel medical insurance as an alternative to Medicare
Travel medical insurance is a short-term policy you buy before your trip that covers medical expenses while you are abroad. It is not the same as travel insurance that covers trip cancellation or lost luggage — you need the medical portion specifically. These policies typically cost $5 to $15 per day for someone over 65, depending on the length of your trip and where you are going.
Travel medical insurance usually covers emergency hospital care, emergency dental care (up to a limit), emergency medical evacuation, and sometimes routine care like doctor visits. It does not cover pre-existing conditions unless you purchase it within a certain number of days of your first trip deposit — usually 14 to 21 days. Read the fine print carefully, because "pre-existing" is defined differently by each insurer.
You can purchase travel medical insurance from travel insurance companies, some travel agencies, and some credit card companies. Compare quotes from at least two providers before you buy. Make sure the policy covers the countries you are visiting — some policies exclude certain regions or countries.
Countries with special Medicare coverage rules
Canada and Mexico are the only countries where Medicare has any coverage at all. In Canada, Medicare covers emergency hospital care and emergency dental care if you are a U.S. citizen traveling there directly from the U.S. In Mexico, the same applies. However, the coverage is limited to true emergencies — not scheduled appointments, not routine check-ups, and not non-emergency dental work.
If you are a U.S. citizen living permanently in Canada or Mexico, you may be able to keep your Medicare coverage and use it for care in that country, but the rules are complex and depend on your specific situation. Contact Medicare directly at 1-800-MEDICARE to ask about your circumstances.
Some U.S. territories like Puerto Rico, the U.S. Virgin Islands, and Guam are treated differently than foreign countries. Medicare Part A (hospital insurance) generally covers care in these territories, but Part B (medical insurance) may not. If you are moving to or spending extended time in a U.S. territory, contact Medicare before you go to understand what will and will not be covered.
Planning ahead: what to do before you leave
Before any international trip, take these steps: First, get a written copy of your current medications and dosages from your doctor, in case you need to see a foreign doctor and cannot communicate your medical history. Second, make a list of any allergies or medical conditions and carry it with you. Third, research hospitals and clinics in your destination — some travel insurance companies provide lists of affiliated providers.
Fourth, notify your Medicare Advantage plan or Medigap insurer that you are traveling, especially if you are going for more than a few weeks. Some plans have specific procedures for overseas travel. Fifth, purchase travel medical insurance if you are going anywhere outside Canada or Mexico. Sixth, make copies of your insurance cards and keep them separate from the originals.
Seventh, check whether your destination country requires proof of health insurance to enter. Some countries do, and travel medical insurance can satisfy that requirement. Eighth, if you are taking controlled medications, research the laws in your destination country and consider carrying a letter from your doctor explaining why you need them.

Frequently Asked Questions
Can I use my Medicare card at a hospital in Europe?
No. Your Medicare card is not recognized outside the U.S., and presenting it will not result in coverage. You will be asked to pay in full at the time of service. Keep your Medicare card with you for identification purposes, but understand that it provides no coverage abroad.
Does travel medical insurance cover pre-existing conditions?
Only if you purchase the policy within a set window — usually 14 to 21 days of your first trip deposit. After that window closes, pre-existing conditions are excluded. Each insurer defines "pre-existing" differently, so read the policy details carefully before you buy.
What if I get sick and have to cancel my trip?
Travel medical insurance does not cover trip cancellation. You need a separate travel cancellation policy for that. Some travel insurance companies sell both together as a package, but they are separate coverages with separate costs.
Can I get Medicare to reimburse me for care I received abroad?
Medicare will not reimburse you for care received outside the U.S., except in the narrow circumstances described above (emergency care in Canada or Mexico under specific conditions). If you paid out of pocket, you cannot submit a claim to Medicare and expect reimbursement.
Do I need travel insurance if I am only going to Canada?
Medicare covers emergency care in Canada, so travel insurance is not strictly necessary. However, Medicare's coverage is limited to true emergencies, and you will still pay out of pocket and submit a claim later. Travel insurance covers you when ready without the hassle of filing a claim, and some policies cover routine care that Medicare does not.
