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

Part A

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.

Part B

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.

Part C

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.

Part D

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.

Which one is you?

Your Medicare decisions are different depending on how long you're planning to be gone.

The 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.

Keep it or drop it — and what the penalty actually costs

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.

Frequently Asked Questions

Does Medicare work outside the US?
Almost nothing follows you. Medicare was built for US-based care and — with three narrow exceptions — only pays US providers. The exceptions: emergencies on a ship within 6 hours of a US port, a foreign hospital that's closer than the nearest US hospital during a medical emergency in the US (common near some border areas), and travel through Canada on the most direct route between Alaska and another US state. For the vast majority of retirees living or spending extended time overseas, Medicare provides zero coverage outside the country.
What parts of Medicare follow you abroad?
None follow you in any meaningful way. Part A (hospital) and Part B (doctor visits, outpatient) share the same three narrow geographic exceptions and cover nothing routine abroad. Part C (Medicare Advantage) plans are largely incompatible with living outside the US — most can auto-disenroll you after 6 months abroad. Part D (prescriptions) covers nothing outside the US. Medigap plans G and N include a foreign travel emergency benefit, but it applies only to emergencies in the first 60 days of a trip, caps out at 80% after a $250 deductible, and doesn't cover medical evacuation.
Do I still pay for Medicare when I live abroad?
Yes — and this is what makes the Part B decision consequential. If you're receiving Social Security, Part B premiums ($202.90/month at the standard rate in 2026) are deducted automatically regardless of where you live. You can choose to disenroll — but doing so triggers a permanent late enrollment penalty if you ever return to the US and re-enroll. The only way to stop paying for coverage that doesn't work where you live is to formally drop it, and that decision has lasting financial consequences.

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.
