Medicare coverage stops at the U.S. border in almost all cases

Medicare does not cover medical care outside the United States, Puerto Rico, the U.S. Virgin Islands, Guam, American Samoa, or the Northern Mariana Islands. If you receive care in any other country, Medicare will not pay for it, and you will be responsible for the full cost. This applies to both Original Medicare (Part A and Part B) and Medicare Advantage plans.

The only exception is a narrow one: if you are in Canada or Mexico and need emergency care for a sudden, serious medical condition, Medicare may cover it — but only if the nearest hospital that can treat you is in that country. Even then, you must return to the U.S. for follow-up care, or Medicare stops paying.

This rule catches many people off guard, especially those who travel frequently or spend winters abroad. Understanding what is and is not covered before you leave can save you thousands of dollars in unexpected medical bills.

Key Takeaways

  • Medicare does not pay for routine or planned medical care in any country outside the United States and its territories.
  • Emergency care in Canada or Mexico may be covered only if it is truly urgent and the nearest suitable hospital is across the border.
  • Travel health insurance is the main way to cover medical costs abroad, and you must purchase it before you leave the U.S.
  • Medicare Advantage plans sometimes offer limited coverage abroad, but you must check your specific plan's rules before traveling.
  • Retirees who move abroad permanently lose Medicare coverage and must arrange their own health insurance in that country.

The emergency care exception in Canada and Mexico

Medicare will pay for emergency inpatient hospital care in Canada or Mexico if two conditions are met: the condition must be sudden and serious, and the nearest hospital capable of treating it must be in Canada or Mexico rather than in the U.S. For example, if you suffer a heart attack while driving through the Canadian border and the closest cardiac center is in Canada, Medicare may cover the emergency admission and stabilization.

However, this exception is narrow and comes with a major catch. Once you are stable enough to travel back to the U.S., Medicare stops paying. If you need ongoing treatment, you must return home or pay out of pocket. Medicare will not cover extended stays or follow-up care abroad, even if you were initially treated under the emergency exception.

You must also be able to prove the emergency was genuine. straightforward choosing a hospital in Mexico because it was cheaper will not may have access to. Medicare reviews these claims carefully, and you may face a bill if the agency decides the condition was not truly emergent.

What Medicare Advantage plans may cover abroad

Some Medicare Advantage plans offer limited coverage for emergency care outside the U.S., and a few offer broader coverage for routine care in certain countries. However, this varies widely by plan and by insurer. A plan available in one state may not offer the same coverage in another, and coverage rules change year to year.

If you have a Medicare Advantage plan and plan to travel or move abroad, contact your plan directly before you leave. Ask specifically: Does your plan cover emergency care outside the U.S.? If so, in which countries? Do you need to notify the plan before traveling? What is the process for filing a claim abroad? Get the answers in writing, because phone representatives sometimes give incorrect information.

Even if your plan does offer some coverage abroad, it is usually limited to emergencies and may require you to use in-network providers. Routine care, dental, vision, and prescription drugs are almost never covered outside the U.S., even under Advantage plans with international riders.

Travel health insurance as a backup

Travel health insurance is a separate policy you purchase for a specific trip or period abroad. It covers medical care you receive outside your home country and is designed to fill the gaps that Medicare leaves. Costs range widely depending on your age, the length of your trip, and the countries you visit, but a two-week trip for someone in their 70s typically costs $100 to $300.

You must purchase travel health insurance before you leave the U.S. — you cannot buy it once you are already abroad. Most policies have a waiting period of 7 to 14 days before they take effect, so plan ahead. Some policies exclude pre-existing conditions or cap coverage at a certain amount, so read the fine print carefully.

Travel insurance does not replace Medicare. Instead, it works alongside it. When you are in the U.S., you use Medicare. When you are abroad, you use the travel policy. Some travel policies will reimburse you for costs Medicare would have covered if you had been home, but you need to check your specific policy to know.

Long-term care abroad and permanent moves

If you move abroad permanently, your Medicare coverage ends. You are no longer a U.S. resident, and Medicare is a U.S. program. You will need to arrange health insurance in your new country, which may be through that country's national health system, a private insurer, or both.

The process for obtaining health insurance abroad depends entirely on the country. Some countries offer free or low-cost care to residents regardless of age or citizenship status. Others require you to be a citizen or permanent resident. Some allow you to purchase private insurance as a foreigner. Before you move, research the health system in your destination country and understand what you will be may have access to to and what it will cost.

If you think you might move abroad later, do not drop your Medicare coverage when ready. You can suspend it temporarily and restart it if you return to the U.S., but the rules are complex. Contact Social Security before you move to understand your options.

Prescription drugs and medical equipment abroad

Medicare Part D (prescription drug coverage) does not work outside the U.S. If you need medications while abroad, you must pay out of pocket or use a local prescription plan in that country. Some medications available by prescription in the U.S. are available over the counter abroad, or under different names, which can make them cheaper — but you cannot rely on this.

Medical equipment such as wheelchairs, walkers, oxygen, or CPAP machines is also not covered by Medicare abroad. If you use durable medical equipment regularly, you will need to arrange for it in your destination country before you arrive. Some equipment can be shipped internationally, but shipping costs are high and customs rules vary by country.

Planning a trip: what to do before you leave

If you are traveling abroad for a short period, take these steps before you depart. First, contact your Medicare plan or Original Medicare to confirm what is and is not covered in your destination. Second, purchase travel health insurance that covers the dates and countries you will visit. Third, get copies of your prescriptions (not just the bottles) in case you need to refill them abroad or explain your medications to a foreign doctor.

Bring your Medicare card and any insurance documents with you, even though Medicare will not pay. Foreign hospitals sometimes ask for proof of insurance to determine how to bill you. Keep receipts for any medical care you receive, because you may be able to file a claim with your travel insurance or use the expenses for tax purposes when you return.

If you take regular medications, research whether they are available in your destination country and under what name. Some countries have different brand names for the same drug. If your medication is not available, ask your doctor before you leave whether there is an alternative you can use while abroad.

Frequently Asked Questions

Can I use my Medicare card at a hospital in Europe?

No. Medicare will not pay for any care you receive in Europe. The hospital may ask to see your Medicare card to understand your insurance status, but it will not process a claim through Medicare. You will be billed as an uninsured patient unless you have travel health insurance that covers Europe.

What if I need dialysis while traveling abroad?

Medicare does not cover dialysis outside the U.S. You must arrange dialysis in advance through the dialysis center in your destination country. Contact your current dialysis provider before you travel to get a referral and your medical records. Travel health insurance may cover some costs, but you should confirm this before you leave.

Does Medicare cover care in Puerto Rico or U.S. territories?

Yes. Medicare covers care in Puerto Rico, the U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands the same way it covers care in the 50 states. You can use your Medicare card at hospitals and doctors' offices in these territories without any special arrangements.

Can I buy travel insurance if I have a pre-existing condition?

Yes, but many travel policies exclude pre-existing conditions or charge higher premiums for them. Some policies will cover a pre-existing condition if you purchase the insurance within 14 days of your first trip deposit. Read the policy details carefully and ask the insurer directly whether your specific condition is covered.

What happens if I am abroad when my Medicare enrollment period ends?

You can still enroll in Medicare or change plans while abroad, but you must do it by the important date. Contact Social Security or Medicare by phone or mail before the important date passes. Being out of the country does not extend your enrollment period, so mark the dates on your calendar before you leave.
