Medicare and US Health Cover When You Move Abroad (2026)
Key takeaways
- “Medicare usually doesn’t cover health care while you’re traveling outside the U.S.” — and it does not cover routine care where you live abroad (Medicare.gov).
- The only exceptions are narrow: certain cruise-ship care within 6 hours of a US port, and emergencies where a foreign hospital is closer than a US one (including the Alaska–Canada route) (Medicare.gov).
- You can keep Medicare while abroad; it simply won’t usually pay for care outside the US.
- Premium-free Part A has no premium and no late penalty, so most people keep it; Part B has a monthly premium and a permanent late-enrolment penalty.
- Dropping Part B to save the premium can trigger a 10%-per-year lifelong penalty if you re-enrol later (Medicare.gov).
- Plan to rely on your host country’s national health system or a private/international health insurance policy.
The core rule: Medicare stops at the US border
Medicare is designed for care delivered inside the United States and its territories. Official guidance states plainly that “Medicare usually doesn’t cover health care while you’re traveling outside the U.S.” and that, in most cases, “you pay all of the costs” (Medicare.gov). For someone moving abroad, the practical upshot is stark: Medicare will not be your health cover in your new country. It does not pay for a GP visit, a hospital stay, prescriptions or ongoing treatment received overseas.
The narrow exceptions where Medicare may pay abroad
There are only a few situations where original Medicare (Parts A and B) may cover foreign care, and they are aimed at people who live in the US, not expatriates:
- Cruise ships: Part B may pay for medically necessary services provided by a licensed doctor while the ship is in a US port or within 6 hours of one (Medicare.gov).
- Emergency, foreign hospital closer than a US one: if you have a medical emergency in the US and the nearest hospital that can treat you is across the border, or you live in the US and a foreign hospital is closer to home than the nearest capable US hospital.
- Alaska–Canada travel: an emergency while travelling the most direct route between Alaska and another US state through Canada, where a Canadian hospital is closest.
None of these help a US citizen who has settled permanently abroad. Note too that some Medigap (Medicare Supplement) policies include limited foreign-travel emergency benefits — useful for trips, but not a substitute for resident health cover (Medicare.gov).
Can you keep Medicare while living abroad? Yes
Moving overseas does not cancel your Medicare. You can remain enrolled in Part A and Part B and continue paying any premiums from abroad. The question is whether it is worth paying for cover you generally cannot use. This is where Part A and Part B need to be considered separately, because their costs and penalties are very different.
Part A vs Part B: what to keep, what to weigh
Part A (hospital insurance) is premium-free for most people who paid Medicare taxes for enough years, and there is no late-enrolment penalty for premium-free Part A. Because it costs nothing and you never lose it, the overwhelming majority of expats simply keep Part A — it is there if you return to or visit the US.
Part B (medical insurance) carries a monthly premium (the standard premium is set each year by Medicare) and, critically, a permanent late-enrolment penalty if you do not sign up when first eligible and later want it. This is the decision that catches expats out.
The late-enrolment penalty trap
If you delay Part B and do not have qualifying coverage, your monthly premium can rise by 10% for each full 12-month period you could have had Part B but didn’t — and that surcharge generally lasts for as long as you have Part B (Medicare.gov). Foreign national health cover does not count as the kind of employer coverage that lets you delay Part B penalty-free. So an expat who drops or skips Part B to avoid paying for unusable cover can face a much higher, lifelong premium if they move back to the US and re-enrol. If you live outside the US and are not entitled to premium-free Part A, you cannot enrol from abroad; instead you get a special enrolment period beginning when you re-establish US residency. Always confirm your exact position with the Social Security Administration before dropping Part B (SSA).
The trade-off, in plain terms: keeping Part B means paying a monthly premium for cover you likely won’t use while abroad; dropping it saves that premium now but risks a permanent penalty and a coverage gap if you return. Many people who intend to move back, or who split time between countries, keep Part B for insurance against that risk; those certain they will never return sometimes drop it. There is no one-size answer — run your own numbers.
What will actually cover you abroad
Since Medicare won’t, you need real cover in your new country. Two main routes exist. First, many countries let residents join their national or public health system once you have legal residency (sometimes after a qualifying period or contributions). Second, private or international health insurance — often called expat health insurance — can cover you worldwide, including or excluding the US as you choose. Before you move, Medicare’s own guidance urges you to explore your options in your destination country; you may qualify for national insurance as a resident, or buy private cover (Medicare — Coverage Outside the US, publication 11037). Line this up so cover starts the day you arrive; do not rely on Medicare as a bridge.
What about Medicare Advantage (Part C) and Part D?
If you have a Medicare Advantage plan (Part C), be aware these plans generally use US provider networks and are meant for people who live in the plan’s US service area; moving permanently out of that area — and certainly out of the country — usually means you must disenrol, which triggers a special enrolment period to return to Original Medicare (Medicare.gov). Part D prescription-drug plans do not cover drugs bought outside the US, and, like Part B, Part D carries its own late-enrolment penalty if you go without creditable drug coverage and sign up later (Medicare.gov). Factor both into your decision: an Advantage or Part D plan you cannot use abroad is rarely worth keeping, but the Part D penalty math is separate from Part B and worth checking with SSA.
A quick pre-move checklist
(1) Decide, with the SSA, whether to keep or drop Part B, factoring in the penalty and your likelihood of returning. (2) Keep premium-free Part A — there’s no downside. (3) Arrange host-country public cover or international private insurance to begin on arrival. (4) If you travel back to the US, check whether Medigap foreign-travel benefits or a travel policy fill short-term gaps. (5) Keep paying any Part B premium on time from abroad if you decide to retain it, to avoid losing coverage.

Frequently asked questions
Does Medicare cover me if I live abroad?
Generally no. Medicare “usually doesn’t cover health care while you’re traveling outside the U.S.”, and it does not cover routine care where you live overseas (Medicare.gov — Travel outside the US).
Are there any exceptions where Medicare pays abroad?
Only narrow ones: certain cruise-ship care within 6 hours of a US port, and emergencies where a foreign hospital is closer than a US one, including the Alaska–Canada route (Medicare.gov).
Should I keep Medicare Part A while living abroad?
Usually yes. Premium-free Part A costs nothing and carries no late penalty, so most people keep it (Medicare.gov — Costs).
What happens if I drop Part B and re-enrol later?
You may face a permanent late-enrolment penalty of 10% for each full 12-month period you could have had Part B but didn’t, added to your premium for as long as you have Part B (Medicare.gov).
Does foreign national health insurance let me delay Part B without penalty?
No. Foreign coverage does not count as the qualifying employer coverage that avoids the Part B penalty; confirm your situation with SSA before deciding (SSA — Medicare).
What should cover my health care abroad instead?
Your host country’s public system once you are a legal resident, or private/international health insurance. Medicare advises arranging cover in your destination before you move (Medicare — publication 11037).
