Does Medicare Cover International Travel?

Picture this: you are three days into a trip to Portugal, you slip on a wet cobblestone in Lisbon, and the doctor at the emergency room says your wrist needs surgery. The clerk at the front desk asks for payment. You hand over your Medicare card, and the clerk looks at it the way you might look at a library card from another country.

That moment surprises a lot of American retirees, because Medicare feels like a promise that follows you everywhere. It does not quite work that way. Below, we go through what Original Medicare, Medigap and Medicare Advantage actually do when you leave the country, the narrow exceptions written into federal rules, and how to close the gaps before you go. All rules are as checked on November 1, 2026.

Where Does Medicare Think "the U.S." Ends?

Medicare uses a precise definition. For coverage purposes, the United States means the 50 states, the District of Columbia, Puerto Rico, the U.S. Virgin Islands, Guam, American Samoa and the Northern Mariana Islands. That is written into federal regulation (42 CFR 411.9), and Medicare.gov repeats it.

So a winter in San Juan or a week on St. Thomas is treated the same as a trip to Florida. Your Medicare works there just as it does at home, with the usual deductibles and coinsurance.

Everywhere else counts as "outside the U.S.", and that includes places that feel close, such as Canada, Mexico, the Bahamas and the rest of the Caribbean.

What Original Medicare Pays Abroad

The short official answer, in Medicare's own words, is that in most cases you pay all of the costs. The U.S. State Department says the same thing more bluntly on its travel insurance page: Medicare and Medicaid do not pay for medical care outside the United States.

There are three narrow exceptions where Original Medicare may pay for care in a foreign hospital:

1. You are in the U.S. when an emergency happens, and a foreign hospital is closer than the nearest U.S. hospital that can treat you. Think of a heart attack in a small town in northern Maine or Washington, where the nearest suitable hospital is across the Canadian border.
2. You are driving between Alaska and another state through Canada, by the most direct route and without unreasonable delay, when an emergency happens, and a Canadian hospital is closer than the nearest U.S. hospital that can treat you. Medicare decides case by case what counts as "without unreasonable delay."
3. 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.

Even in these cases, coverage is limited. Part A pays for inpatient care after you have been formally admitted. Part B pays for doctor and ambulance services immediately before and during that covered stay. Medicare will not pay for a return ambulance trip home or for follow-up doctor visits after the foreign hospital stay ends. Foreign hospitals are not required to bill Medicare, so you may have to pay up front and file a claim yourself with form CMS-1490S.

Notice what is missing from the list: a vacation emergency in Paris, Cancún or Tokyo. None of the exceptions cover an ordinary trip abroad.

The Cruise Ship Rule

Cruises are a gray zone, and the rule is very specific. Medicare Part B may pay for medically necessary care on a ship if the doctor is legally allowed to provide care on board and the ship is in a U.S. port, or no more than six hours from one, when you get the care. That applies whether or not it is an emergency.

Once the ship is more than six hours from a U.S. port, Medicare does not pay. On a seven-night Caribbean cruise from Miami, that is most of the trip. On an Alaska cruise that starts in Vancouver, Canada, the six-hour clock is tied to U.S. ports along the way, so check the itinerary carefully. If you are planning one, our guide on the best time to cruise Alaska covers the routes.

Shipboard medical centers usually charge cruise passengers directly, and serious cases may require evacuation to a hospital on land, which is where the real costs begin.

Medigap Plans and the $50,000 Foreign Travel Benefit

If you have Original Medicare plus a Medicare Supplement Insurance (Medigap) policy, you may have more protection than you think. According to Medicare.gov, Medigap Plans C, D, F, G, M and N include a foreign travel emergency benefit.

Here is how the benefit works, according to Medicare's official guide:

That benefit is real and useful, but read the fine print. It covers emergencies only, not planned care or routine checkups. You pay 20% of the bill after the deductible, with no out-of-pocket cap. The $50,000 is a lifetime limit, not a per-trip limit. And if your trip lasts longer than 60 days, an emergency that begins on day 61 is not covered at all.

Plans C and F cannot be bought by people who became eligible for Medicare on or after January 1, 2020, so most new retirees choosing Medigap today are looking at Plan G or Plan N, both of which include the benefit.

Medicare Advantage Plans Vary Widely

Medicare Advantage (Part C) plans are sold by private insurers, and they set their own rules for care abroad. Some include emergency and urgent care worldwide, sometimes with a dollar cap. Others cover nothing outside the U.S. You cannot assume either way.

Before you travel, call the number on your card and ask three questions: Does my plan cover emergency care outside the U.S.? Is there a dollar limit? Do I pay first and get reimbursed? Ask the insurer to put the answer in writing, or find it in your plan's Evidence of Coverage document.

Prescriptions, Vaccines and the Things People Forget

Medicare drug plans (Part D) do not cover prescription drugs you buy outside the U.S. If you lose your pills in Rome, you will pay the pharmacy yourself. Pack enough medication for the whole trip plus a few extra days, keep it in your carry-on, and bring copies of your prescriptions with generic drug names.

There is one piece of good news on the travel health side. According to Medicare.gov, Part D covers vaccines recommended by the CDC's Advisory Committee on Immunization Practices, including some travel vaccines such as yellow fever, chikungunya and Japanese encephalitis, with no deductible or copay for those vaccines. Get them at home before you go. If you are heading to West Africa, for example, our guide to Ghana vaccine requirements explains what is required at the border.

The biggest gap of all is medical evacuation. The State Department estimates that an air ambulance back to the United States can cost from $20,000 to $200,000, depending on where you are and your condition. Neither Original Medicare nor Medigap pays for that flight home.

How to Close the Gap Before You Go

For most Medicare travelers, the practical answer is a short-term travel medical insurance policy, ideally one that includes medical evacuation and repatriation. A few points to look for:

• Medical coverage, not just trip cancellation. Many travel insurance policies focus on canceled flights and lost bags. Make sure the policy has a clear limit for emergency medical expenses abroad.
• Evacuation and repatriation. This covers transport to a hospital that can treat you, and the flight home. The State Department strongly recommends it for areas with higher risk or limited medical care.
• Age limits and pre-existing conditions. Some policies raise prices sharply after age 70 or 75, or exclude conditions you already have unless you buy within a set number of days of your first trip payment.
• Primary or secondary coverage. A primary policy pays first; a secondary one may wait for your other insurance to deny the claim.
• Direct billing. Some policies pay foreign hospitals directly, which saves you from fronting a large bill.

Your state's State Health Insurance Assistance Program (SHIP) gives free, unbiased counseling on Medicare and Medigap, and it is a good place to check what your current coverage includes. You can find your local office at shiphelp.org. For more on the bigger picture, see our travel insurance and health and vaccinations pages.

A Simple Checklist for Medicare Travelers

Before you board, you should be able to answer these with a yes:

• I know whether my Medigap or Medicare Advantage plan covers emergencies abroad, and up to what limit.
• I know my trip length, and whether it runs past the 60-day Medigap window.
• I have travel medical insurance with evacuation, or I have decided consciously to go without.
• My medications are packed in my carry-on, with written prescriptions.
• I have my insurer's international assistance phone number saved in my phone and on paper.

Medicare is excellent at home. Abroad, treat it as a starting point, not a safety net.
