Domestic Travel: Across State Lines
Original Medicare (Parts A and B) works the same in all 50 states, Washington D.C., Puerto Rico, Guam, the U.S. Virgin Islands, American Samoa, and the Northern Mariana Islands. You can see any provider that accepts Medicare, regardless of which state you're in. This is one of Original Medicare's key strengths for travelers.
Medicare Advantage plans are a different story. Most MA plans use local provider networks. If you need non-emergency care while traveling in another state, you may need to pay out-of-network rates or the plan may not cover the visit at all. Some MA plans — particularly PPOs — offer broader out-of-network coverage, but always check before you travel.
International Travel: Very Limited Coverage
As a general rule, Medicare does not cover healthcare outside the United States. This is one of the most important gaps to understand before booking international travel.
There are limited exceptions where Medicare may pay for care outside the U.S.:
- You have a medical emergency in the U.S. and a foreign hospital is closer than the nearest U.S. hospital.
- You are traveling through Canada by the most direct route between Alaska and another state, and you need emergency care.
- You live near the U.S.–Canada or U.S.–Mexico border, and the closest hospital is across the border (regardless of emergency).
Filling the Gap: Medigap and Travel Insurance
Two options can help cover you abroad:
- Medigap Plans C, D, F, G, M, and N include a “foreign travel emergency” benefit. It typically covers 80% of emergency care costs during the first 60 days of a trip, after a $250 deductible, with a lifetime limit of $50,000. Plans that do not include this benefit: Plans A, B, K, and L.
- Standalone travel medical insurance is designed for international coverage and may offer broader benefits — including medical evacuation — than the limited Medigap foreign travel benefit. Policies vary widely in cost and coverage, so compare carefully.
Prescription Drugs Abroad
Medicare Part D does not cover prescriptions filled at pharmacies outside the United States. If you take medications regularly, bring enough supply to last your entire trip plus a buffer. Carry your prescriptions in their original containers and keep a copy of your prescription list with generic drug names (brand names may differ internationally).
A Travel Checklist for Medicare Beneficiaries
- Carry your Medicare card and any supplemental insurance cards.
- If on Medicare Advantage, confirm the plan's out-of-area and emergency policies before departure.
- For international trips, purchase travel medical insurance that covers your destinations.
- Pack enough prescription medication for the entire trip, plus extra days.
- Keep an updated list of your medications, conditions, and emergency contacts.

Original Medicare generally covers you anywhere in the U.S. and its territories as long as the provider accepts Medicare. Medicare Advantage plans may limit coverage outside their network except for emergencies.
What about international travel?
Original Medicare usually does not cover care outside the United States, aside from a few limited exceptions. Some Medigap plans include limited foreign travel emergency benefits.
How can travelers close the international gap?
Options may include a Medigap plan with foreign travel emergency coverage or a separate travel medical insurance policy for trips abroad. Checking the specific limits before you go is wise.
