In general, no. Medicare Part A (inpatient care) and Medicare Part B coverage is usually not covered as you travel outside the United States or U.S. Territories including: American Samoa, Guam, the Northern Mariana Islands, Puerto Rico ("Estado Libre Asociado de Puerto Rico"), and US Virgin Islands.
However, "Medicare may pay for inpatient hospital, doctor, ambulance services, or dialysis you get in a foreign country in these rare cases:
- You are in the United States when a medical emergency occurs, and the foreign hospital is closer than the nearest U.S. hospital that can treat your medical condition.
- You are traveling through Canada without unreasonable delay by the most direct route between Alaska and another state when a medical emergency occurs, and the Canadian hospital is closer than the nearest U.S. hospital that can treat the emergency.
- You live in the U.S. and the foreign hospital is closer to your home than the nearest U.S. hospital that can treat your medical condition, regardless of whether an emergency exists.
- In some cases, Medicare may cover medically necessary health care services you get on board a ship within the territorial waters adjoining the land areas of the U.S. Medicare won't pay for health care services you get when a ship is more than 6 hours away from a U.S. port."

If you do not have a Medigap policy that provides

consider buying a travel insurance policy that includes health coverage
-- speak with your travel agent or insurance agent about your options.
