Does Medicare cover you abroad? Here's the honest answer.
The short answer: Original Medicare generally pays nothing for health care outside the United States. There are three narrow exceptions, a partial backstop if you have certain Medigap plans, and a "check your plan" answer for Medicare Advantage. That's the whole landscape in three sentences. The rest of this article explains each piece, because the details decide whether a trip abroad puts your savings at risk.
I've been in the travel business for more than 35 years and have sold travel insurance for over 20 of them, mostly to travelers in their 60s and 70s. This is the single most consequential thing my clients don't know until someone tells them.
What "the United States" means to Medicare
Medicare's map includes the 50 states, D.C., and the U.S. territories: Puerto Rico, the U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands. A trip to San Juan is a domestic trip as far as Medicare is concerned. A trip to Vancouver, Cancun, Rome, or a cruise ship six hours past Miami is not.
The three exceptions
Original Medicare can pay for care outside the U.S. in exactly three situations, and all of them are rare:
- You're in the U.S. when an emergency happens, and a foreign hospital is closer than the nearest U.S. hospital that can treat you.
- You're traveling between Alaska and another state through Canada without unreasonable delay, and a Canadian hospital is the closest one that can treat an emergency.
- You live in the U.S. and a foreign hospital is closer to your home than the nearest U.S. hospital that can treat your condition, emergency or not.
Notice what's not on that list: every vacation you will ever take. The exceptions exist for border geography, not for travel.
Medigap: a real benefit with a hard ceiling
If you carry a Medigap (Medicare Supplement) plan, you may have more help than Original Medicare alone. Plans C, D, F, G, M, and N include a foreign travel emergency benefit. Here is exactly what it pays:
- 80% of billed charges for emergency care, after a $250 annual deductible
- Only for emergencies that begin during the first 60 days of your trip
- Up to a lifetime maximum of $50,000
Each of those three lines deserves a hard look. The 80% means you owe one dollar in five of a foreign hospital bill. The 60-day rule means a longer stay abroad runs out of protection mid-trip. And the $50,000 lifetime cap is the big one: it is not per trip, not per year, but for your whole life, and a single medical evacuation can exceed it on its own.
Medigap's travel benefit is a genuinely useful backstop for a small emergency. It was never designed to be your medical coverage abroad.
Medicare Advantage: the answer is in your plan documents
Medicare Advantage plans must cover everything Original Medicare covers, which, abroad, is almost nothing. Some plans add emergency or urgent care coverage overseas as an extra benefit, with their own limits and rules. Some don't. One more wrinkle worth knowing: stay outside the U.S. for more than six months and your Advantage plan can disenroll you.
If you have Advantage and a trip booked, call your plan and ask three questions: Do you cover emergencies outside the U.S.? What's the dollar limit? How do I file a claim from abroad? Write the answers down and take them with you.
The part nobody warns you about: paying up front
Even where some reimbursement exists, foreign hospitals don't bill Medicare, and many won't bill anyone. They expect payment at the time of service, sometimes before treatment, sometimes before discharge. So the practical question isn't only "what will I get back later." It's "can I hand a hospital in another country a five-figure payment today."
Good travel insurance plans address this directly: their assistance lines can arrange and guarantee payment to foreign hospitals, which is a benefit that never shows up in a coverage table but matters enormously at 2 a.m. in a country where you don't speak the language.
What actually fills the gap
A travel insurance plan with real medical benefits does three things Medicare can't do abroad:
Emergency medical coverage that travels. The plans we sell from Travelex, Faye, and USI carry emergency medical limits in the hundreds of thousands of dollars, valid wherever your trip goes.
Medical evacuation. Transport to an adequate hospital, and home if needed. This is the most expensive risk in all of travel and the reason I check evacuation limits before anything else on a quote.
A 24-hour assistance line. Someone to find the right hospital, manage payment guarantees, and coordinate with your family while you're being treated.
And because these are full travel insurance plans, they also cover the trip itself: cancellation, interruption, baggage, and delays. Different subject, same policy.
Common questions
Does Medicare cover me in Canada or Mexico?
Generally no. The narrow exceptions above are about border geography and emergencies, not vacations. Plan as if the answer is no.
Does Medicare cover me on a cruise?
Only while the ship is in a U.S. port or within six hours of one. We wrote a full guide on Medicare and cruises, because the six-hour rule surprises almost everyone.
I have a Medigap plan. Is that enough for a two-week trip to Europe?
You have a backstop: 80% after $250, $50,000 lifetime cap, first 60 days only. Whether that's "enough" depends on how you feel about the 20% and the cap. Most of my clients treat Medigap as the backup and a travel plan as the coverage.
Does travel insurance replace Medicare while I'm abroad?
No. It works alongside whatever you have, covering the emergency care, evacuation, and trip costs that Medicare doesn't touch outside the U.S.
The bottom line
Inside the United States, Medicare is the foundation of your health coverage. Step outside, and the foundation stays home. The gap is real, it's well documented, and it's exactly the gap a travel insurance plan with strong medical and evacuation benefits exists to fill.
Every policy is different, and the policy document, not this article, decides what's covered. To see the plan that fits your trip, our four-question quiz takes about two minutes.
