International travel in retirement is one of life’s great pleasures—and one of its more significant financial risks for Medicare beneficiaries. The average American traveler doesn’t realize until they’re abroad that the Medicare card in their wallet is essentially useless outside US borders. Here’s exactly where coverage stops, what the exceptions are, and how to protect yourself.

The Three Narrow Exceptions
Original Medicare makes three specific exceptions where international care may be covered. All three are emergency scenarios—not routine or planned medical care abroad.
Exception 1: Emergency Care in Canada or Mexico When the US Hospital Is Farther
If you have a medical emergency in the US but the nearest hospital is in Canada or Mexico — closer than any US hospital — Medicare may cover the emergency care received at that foreign hospital. This primarily applies to people living near the Canadian or Mexican border. The key qualifier is that the foreign hospital must be closer than any US hospital that can treat you.
Exception 2: Emergency Care in Canada While Traveling Between Alaska and the Contiguous US
If you are traveling between Alaska and another US state, and the most direct land route passes through Canada, Medicare covers medically necessary emergency care in Canada along that route. This recognizes that Alaska is geographically separated from the rest of the US and travel through Canada is sometimes the only practical option.
Exception 3: Cruise Ship Emergency Within 6 Hours of a US Port
If you are on a cruise ship and the ship is within 6 hours (by sailing) of a US port, Medicare Part B may cover emergency services provided on the ship by a doctor enrolled in Medicare. Once the ship is more than 6 hours from port, coverage stops — which means for most of a typical cruise itinerary, you have no Medicare coverage.
These three exceptions are narrow and situational. For the vast majority of international travel—a cruise through the Mediterranean, a trip to Europe, a visit to family in another country, a tour of Asia—Original Medicare provides zero coverage.
Medigap Foreign Travel Emergency Coverage
How the Medigap foreign travel emergency benefit works:
- Benefit trigger: A medical emergency that begins during the first 60 days of a trip outside the US
- Deductible: $250 per trip (you pay the first $250 of emergency costs)
- Coverage level: 80% of medically necessary emergency care after the deductible
- Lifetime maximum: $50,000 (this is a lifetime cap, not per-trip)
- What qualifies: Emergency hospital care, emergency physician services, emergency surgery — care that cannot wait until you return to the US
- What does not qualify: Routine care, elective procedures, non-emergency care, care after the first 60 days of a trip
The $50,000 lifetime cap is an important limitation. A serious illness requiring extended hospitalization in a high-cost country (Switzerland, Japan, UK, Australia) can easily exceed $50,000. The Medigap foreign travel benefit is a helpful safety net for typical emergencies—a broken hip, appendicitis, or cardiac event—but it is not comprehensive international health insurance.
What Happens When the Medigap Cap Isn’t Enough
For travelers who want more robust international coverage, supplemental travel medical insurance is the answer. Travel medical insurance specifically designed for seniors is widely available and affordable:
| Coverage Type | What It Covers | Approximate Cost |
|---|---|---|
| Travel medical insurance (primary) | Emergency and non-emergency medical care abroad, no US primary insurance required | $50–$200 per trip depending on age, duration, destination |
| Travel medical insurance (secondary/excess) | Medical costs beyond what any other coverage pays | Less expensive; supplements Medigap foreign travel benefit |
| Medical evacuation coverage | Air transport back to the US for medical treatment | Often included in comprehensive travel plans; or $200–$400 standalone annual plan |
| Annual multi-trip travel medical plan | Covers multiple international trips per year | $200–$600/year for seniors 65+ |
What to Do Before Every International Trip
- Check your Medigap plan. Confirm whether your plan includes the foreign travel emergency benefit and review the $250 deductible and $50,000 lifetime cap. Know your remaining cap if you’ve used the benefit before.
- Purchase travel medical insurance for the trip. For trips beyond the Medigap emergency safety net, purchase a travel medical policy with primary coverage, medical evacuation, and ideally trip cancellation for trip investments over $3,000.
- Carry your information in writing. Bring a card listing your Medicare number, Medigap plan information, travel insurance policy number and 24-hour claim line, and emergency contact information. Foreign hospitals will often require payment upfront — having your travel insurer’s phone number allows them to provide a guarantee of payment.
- Know that Medicare Advantage has different rules. If you have a Medicare Advantage plan, check your Evidence of Coverage for international emergency provisions—some plans do offer limited overseas emergency coverage. Call your plan before your trip.
- Consider destination-specific risks. Some destinations have very high medical costs (Western Europe, Japan, Australia, Scandinavia). Others have limited quality of care that may require evacuation. Tailor your coverage level to your specific itinerary.
Frequently Asked Questions
Does Medicare cover medical care in Canada?
Only in the two narrow exceptions described above—emergency care near the US border when the US hospital is farther and emergency care while traveling through Canada between Alaska and the contiguous US. Routine medical care, planned procedures, or emergencies in Canada that don’t meet these exceptions are not covered.
Does Medicare cover medical care in Mexico?
Only if you live in the US near the Mexican border and the nearest hospital to an emergency is in Mexico. Planned dental or medical tourism in Mexico — which is popular for cost reasons — is not covered by Medicare regardless of the circumstances.
I live near the Canadian border and see a Canadian doctor regularly. Does Medicare cover those visits?
No. Routine care with a Canadian physician — even for a border resident — is not covered by Medicare. The border exception applies only to emergency care where no US hospital is closer.
What if I retire abroad? Does Medicare cover me?
No. If you retire to another country, Original Medicare does not cover your medical care there. You would retain your Medicare eligibility and could use it if you return to the US — but for ongoing care in your country of retirement, you would need that country’s local coverage, private expatriate health insurance, or a combination. Medicare Parts A and B premiums must still be paid to maintain coverage for when you do return to the US.
Does Medicare Part D cover prescriptions I fill in another country?
No. Medicare Part D prescription drug coverage applies only to drugs dispensed at US pharmacies. Prescriptions filled at pharmacies in Canada, Mexico, or any other country are not covered by Part D. Take an adequate supply of medications for your entire trip, or be prepared to pay out of pocket abroad.
