Medicare coverage stops at the U.S. border

Medicare does not cover medical care you receive outside the United States, Puerto Rico, the U.S. Virgin Islands, Guam, American Samoa, or the Northern Mariana Islands. If you become ill or injured while traveling internationally, you will pay the full cost of any doctor visits, hospital stays, or prescriptions out of your own pocket. Medicare will not reimburse you later, even if you see a U.S. doctor after you return home to treat a condition that started abroad.

This applies to all parts of Medicare — Part A (hospital insurance), Part B (medical insurance), and Part D (prescription drug coverage). The only exception is if you are in a country that borders the U.S. (Canada or Mexico) and you need emergency care at a hospital closer to you than the nearest U.S. hospital. Even then, Medicare covers only the emergency itself, not routine or follow-up visits.

Many seniors discover this gap when they travel and face unexpected medical bills. Understanding what is and is not covered before you leave helps you plan and protect yourself financially.

Key Takeaways

  • Medicare does not pay for any medical care received outside the United States and its territories, even if you are a U.S. citizen.
  • Travel medical insurance is a separate purchase that covers emergency and routine care abroad, and costs roughly $100 to $300 for a two-week trip depending on your age and health.
  • If you take prescription medications, you should carry copies of your prescriptions and ask your doctor whether your medications are available or have different names in the countries you plan to visit.
  • Medicare Part D coverage ends when you leave the U.S., so you cannot refill prescriptions abroad using your Medicare drug plan.
  • Some credit cards and travel insurance plans sold by travel agencies include medical coverage, but you must read the fine print to confirm the coverage limits and what counts as an emergency.

Why Medicare does not cover international care

Medicare is a U.S. federal program funded by U.S. payroll taxes and general revenue. It is designed to cover care within the U.S. health system, where Medicare has agreements with hospitals and doctors about payment rates and quality standards. Outside the U.S., Medicare has no such agreements and cannot enforce its payment rules.

Countries have their own health systems, insurance requirements, and payment structures. Medicare cannot negotiate rates or verify that care meets U.S. standards. Rather than attempt to manage claims from dozens of countries with different systems, Medicare straightforward does not cover care abroad. This is true whether you travel for vacation, to visit family, or for medical tourism.

Travel medical insurance as an alternative

Travel medical insurance is a separate policy you buy before you leave the U.S. It covers emergency and sometimes routine medical care while you are outside your home country. For seniors, a typical two-week policy costs between $100 and $300, depending on your age, the length of your trip, and the countries you visit. Policies for longer trips or for travelers over 75 cost more.

Travel medical insurance usually covers emergency room visits, hospital stays, emergency dental care (up to a limit), and evacuation back to the U.S. if you need specialized care. Some policies also cover routine doctor visits and prescription refills. Read the policy details carefully, because coverage limits vary widely — some policies cap emergency room visits at $500, while others cover up to $100,000 in hospital costs.

You can buy travel medical insurance from travel insurance companies (such as World Nomads, IMG Global, or Allianz), through travel agencies, or sometimes through your credit card company. Buy the policy before you leave the U.S., because you cannot purchase it once you are already abroad. Some policies have a waiting period before they take effect, so read the terms.

Prescription medications and international travel

If you take regular medications, plan ahead. Medicare Part D does not cover prescriptions filled outside the U.S. You cannot use your Medicare drug plan to refill medications while you are abroad. Instead, ask your doctor for a written prescription (not just a refill authorization) before you leave, and bring enough medication for your entire trip plus a few extra days.

Carry your prescriptions in their original labeled bottles with your name on them. U.S. Customs allows you to bring a 90-day supply of medication for personal use. If you are traveling for longer than 90 days, contact your doctor's office before you leave to discuss options.

Many medications sold in the U.S. are available in other countries, but under different brand names or in different strengths. Before you travel, ask your doctor or pharmacist to write down the generic name of each medication you take, the dose, and how often you take it. This information helps a foreign doctor or pharmacist understand what you need if you run out or lose your supply. Some countries require a local prescription even if you have a U.S. prescription, so this step saves time.

What to do if you need emergency care abroad

If you become seriously ill or injured while traveling, go to the nearest hospital or call emergency services (the number varies by country — research it before you leave). Tell the hospital staff that you are a U.S. citizen and that Medicare will not cover the cost. Ask for an itemized bill and receipts for all services, medications, and supplies.

After you return to the U.S., you can submit the bill to your travel medical insurance company if you purchased a policy. Keep all documentation — receipts, hospital discharge papers, and proof of payment. Do not expect Medicare to reimburse you, but your travel insurance or a credit card company might, depending on your coverage.

If the bill is very large and you cannot pay it, contact the hospital's billing department to ask about payment plans. Some hospitals offer discounts for uninsured patients or have financial information programs, though these vary by country and institution.

Planning your trip with Medicare in mind

Before you book international travel, take these steps. First, talk to your doctor about your trip and any health concerns. Ask whether your current medications are safe to take while traveling and whether you need any vaccinations or preventive care before you leave. Some countries require proof of certain vaccinations for entry.

Second, research travel medical insurance and buy a policy that covers the countries you plan to visit and the length of your stay. Third, get written prescriptions for all your medications and carry them with you. Fourth, make a list of your medications, doses, and any allergies, and keep a copy in your wallet and another with a family member at home.

Fifth, research the health care system in the countries you are visiting. Some countries have excellent hospitals in major cities but limited care in rural areas. Know where the nearest hospital is to your hotel or destination. Sixth, register with the U.S. State Department's Smart Traveler Enrollment Program (STEP) before you leave. This allows the embassy to contact you in case of an emergency at home or a crisis in the country where you are traveling.

Medicare coverage in U.S. territories

Medicare does cover care in Puerto Rico, the U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands. These are U.S. territories, and Medicare has agreements with hospitals and doctors there. However, not all Medicare providers operate in every territory, and some services may be limited. Before you travel to a U.S. territory, call your Medicare Advantage plan or contact Medicare directly to confirm that your coverage is active in that location.

If you are a snowbird who spends part of the year in Puerto Rico, you can keep your Medicare coverage there. However, you must still live in the U.S. for at least part of the year to remain enrolled in Medicare. Talk to Medicare about your situation if you spend extended time outside the U.S.

Frequently Asked Questions

Will Medicare pay if I go to Canada or Mexico for medical care?

Medicare covers emergency care only if you are in Canada or Mexico and the nearest hospital that can treat your emergency is in that country. Routine care, dental work, and elective procedures are not covered. If you plan to visit Canada or Mexico, purchase travel medical insurance to cover any care you might need.

What if I have a Medicare Advantage plan instead of Original Medicare?

Medicare Advantage plans also do not cover care outside the U.S., with the same exception for emergencies in Canada or Mexico. Some Advantage plans offer travel benefits or emergency coverage abroad, so check your plan documents or call your plan to ask. Even if your plan offers some coverage, it is usually limited, so travel medical insurance is still a good idea.

Can I use my Medicare card to get discounts on medical care while traveling?

No. Your Medicare card is not accepted outside the U.S. and does not may have access to you to any discounts or coverage abroad. Bring your card for your records, but do not expect it to be useful for paying for care.

Do I need to tell Medicare I am traveling?

You do not need to notify Medicare before you travel. Your coverage remains active while you are abroad, but it will not pay for any care you receive outside the U.S. If you are away for an extended period and have questions about your coverage, you can call Medicare at 1-800-MEDICARE to confirm your status.

What should I do if I get sick and cannot afford travel medical insurance?

If you are already abroad and did not purchase travel insurance, contact your travel company, hotel, or embassy for help finding affordable care. Many countries have public hospitals that treat uninsured patients, though wait times may be long. Ask the hospital about payment plans or financial information. When you return to the U.S., contact your doctor to follow up on any condition that started during your trip.
