Medicare for Expats: What US Retirees Need to Know
Medicare was built for the US — and almost none of it follows you abroad. For expats and Medicare, the relationship is straightforward: you keep paying premiums, but the coverage doesn't cross borders. For retirees making a permanent move, that means no coverage for routine care outside the country and a real decision about whether to keep paying Part B. This guide explains what each part covers, where the narrow exceptions are, and where to go next based on your situation.

Do you lose Medicare when you move abroad?
No. Your enrollment stays — moving doesn't cancel Part A or Part B, and Social Security keeps deducting the Part B premium from wherever you live. What changes is the coverage. Parts A, B, and D pay essentially nothing outside the US (the three narrow exceptions are above), and a Medicare Advantage plan can auto-disenroll you after roughly 6 months out of the country.
So you don't lose Medicare. You lose the coverage it provides, while you keep paying for it. The real decision is whether to drop Part B — and that's a one-way door, because re-enrolling later triggers a permanent late-enrollment penalty.
How this plays out depends on whether you're leaving for good or splitting time. See Medicare for permanent movers for the leaving-for-good math, or the Part B abroad guide for the keep-or-drop break-even.
The Four Parts of Medicare
Hospital Insurance
Covers inpatient hospital stays, skilled nursing, hospice, and some home health care.
Free for most people (if you paid into Social Security for 10+ years). Keep it — always.
Medical Insurance
Covers doctor visits, outpatient care, lab work, and preventive services. Costs $202.90/month in 2026 at standard income — higher earners pay more.
Covers nothing outside the US. Whether to keep paying for it is your biggest Medicare decision.
Read our Part B abroad guide →Medicare Advantage
A private insurance plan that replaces Parts A and B, usually bundling drug coverage and extras like dental and vision.
Largely incompatible with living overseas — and there's a rule that can auto-disenroll you.
Read our Medicare Advantage abroad guide →Prescription Drug Coverage
Covers prescription medications in the US. As of 2026, includes an annual out-of-pocket cap.
Covers nothing outside the US. Dropping it triggers a separate permanent penalty — same logic as Part B.

Your Medicare decisions are different depending on how long you're planning to be gone.
Going abroad for a year or two, not sure yet
Keeping Part B is almost always the right call. Dropping it locks in a permanent penalty if you return — and the break-even takes a decade.

If you're on Medicare Advantage, there's a 6-month rule most snowbirds don't find until it's caused a problem.

At 8–10 months abroad, Medicare Advantage disenrollment isn't a risk — it's certain. Here's the coverage stack that actually works.
See the guideLeaving for good — or mostly sure you are
The only scenario where dropping Part B is worth considering. The math depends on your age, how often you'll visit, and how certain you are.
See the guideThe Part B Decision
Should you keep paying $202.90/month for coverage that doesn't work overseas — or drop it and risk a permanent penalty if you return? The answer depends on how permanently you're leaving.

Four scenarios, the penalty math, and the break-even calculations that tell you whether dropping Part B makes financial sense for your situation.
On a Medicare Advantage Plan?
More than half of all Medicare enrollees are on a Part C Advantage plan. There's a rule buried in the fine print that most people don't find out about until it's already caused a problem.
The 6-month abroad rule — and what to do about it
Advantage plans can auto-disenroll you if you're outside the US for more than 6 months. What that means, how to switch before it happens, and how to protect your Medigap options.
Should You Add Medigap Before You Go?
Original Medicare has real gaps — and there's a one-time window to fill them without medical underwriting. Miss it at 65 and most states allow insurers to turn you down or charge more based on your health history.
For a plain walkthrough of how bundling Original Medicare + Part D + Medigap compares to Medicare Advantage, see Medicare Interactive's guide to living abroad. The mechanics are right; the expat-specific decisions are still yours.

What covers you when Medicare doesn't?
For most well-prepared retirees living internationally, it's an international health plan. A hospital stay can run $5,000–20,000 out of pocket. Medical evacuation: $50,000–100,000 or more. A full plan for a 65-year-old runs $150–300/month — not a premium, just the math on not self-insuring a six-figure exposure.
