Does Medicare Cover Medical Care Outside the United States?
Last Modified: 10/06/2026 | Reviewed by Keith Armbrecht (NPN 634015)
Quick Summary
Original Medicare usually doesn’t cover healthcare you receive outside the United States.
There are a few limited exceptions, including certain emergencies near the U.S. border and certain situations involving travel through Canada between Alaska and another state.
Because Medicare’s international coverage is limited, people who travel outside the country should understand what Medicare, Medigap and separate travel medical insurance will and won’t cover.
Key Facts
Medicare generally considers the following part of the United States:
- 50 states
- District of Columbia
- Puerto Rico
- S. Virgin Islands
- Guam
- Northern Mariana Islands
- American Samoa
Healthcare elsewhere is generally considered care outside the U.S.
When Can Original Medicare Pay Overseas?
There are limited circumstances.
Emergency Near a Foreign Hospital
If you’re in the U.S. when a medical emergency occurs and a foreign hospital is closer than the nearest U.S. hospital capable of treating you, Medicare may cover qualifying services.
Traveling Between Alaska and Another State
Medicare may cover certain emergency services at a Canadian hospital when you’re traveling:
without unreasonable delay
by the most direct route between Alaska and another U.S. state, and the Canadian hospital is closer than an appropriate U.S. hospital.
Foreign Hospital Closer to Your U.S. Home
If you live in the United States and a foreign hospital is closer to your home than the nearest U.S. hospital capable of treating your condition, Medicare may cover certain services even when it isn’t an emergency.
What About Cruise Ships?
Part B may cover medically necessary services aboard a cruise ship in certain circumstances when the ship is:
- In a U.S. port
- Or no more than six hours away from a U.S. port
and other Medicare requirements are satisfied.
Does Part D Cover Prescriptions Purchased Overseas?
Medicare drug plans generally don’t cover prescription drugs purchased outside the United States.
What About Medigap?
Several Medigap plans offer limited:
Foreign Travel Emergency Coverage
Plans G and N are among the standardized Medigap plans that include this benefit.
Do You Need Travel Medical Insurance?
Possibly.
Because Medicare and Medigap foreign coverage can be limited, frequent international travelers may want to consider separate travel medical insurance.
Video Explanation from Keith
Does Medicare Cover You Outside the United States?
Keith's Take
If you travel internationally, don’t assume your Medicare card works the same way overseas as it does in Florida or another U.S. state.
It usually doesn’t.
If you have Plan G or Plan N, you do have some foreign-travel emergency protection, but it’s limited.
For a major international trip, especially a long one, I would look at travel medical coverage separately.
