Medicare for American Retirees in France: The Complete Guide

Picture a couple in their late sixties, two years into a new life outside Bordeaux. Between them, they pay just over $400 a month for Medicare Part B. Neither has seen an American doctor since they arrived. They are enrolled in the French healthcare system, perfectly happy with it, yet their US premiums vanish from their bank account every month.

The obvious move seems to be stopping the payments. You can always sign back up later if you return, right?

Reversing that decision comes with a penalty added to your premium for the rest of your life.

Because we coordinate moves to France for a living, our instinct is to help clients keep their options open. But this decision involves real trade-offs, so before offering a recommendation, let's look at how the system actually works.

Medicare has four parts. Only one requires a real decision.

Part A

About 99% of beneficiaries pay no premium for it, according to CMS, the agency that runs Medicare, though there are still deductibles if you end up using it. It won't cover a hospital stay in Lyon, but it will pay if you're admitted while visiting Chicago. Some people want to cancel everything on the way out, for a clean break. Don't. Dropping Part A while you're drawing Social Security means withdrawing your Social Security application altogether and repaying every dollar it has paid you, plus what Medicare has spent on your care.

One exception applies to the small group without premium-free Part A. Buying it requires US residence, so a citizen living in France at 65 can't buy it yet: the seven-month enrollment window opens only when you re-establish US residence, the month you move plus three months on either side, and you can file up to three months ahead. Enroll in that window and you owe no late penalty on Part A or Part B. Premium-free Part A can also come through a spouse's, former spouse's, or late spouse's record, or railroad and certain government service, so your own 40 quarters aren't the whole test, and the rules are more involved for non-citizens. Confirm your position with Social Security.

Parts C and D

These are separate private plans, not coverage you hold by default. Part C replaces your A and B benefits through an insurer, and Part D is a drug policy you buy on your own, which is exactly why neither survives the move. It's on you to notify your insurer that you're leaving, and when coverage ends depends on the plan's own procedures. If you're dropping a Part C plan, you'll usually qualify for a special window to move back to Original Medicare. Don't expect to keep paying quietly and stay covered from France.

Part B

This is the one you actually have to decide about, and your question depends on where you're starting from.

• If you're 65 or older and already enrolled: Part B is in place, so the question is whether to keep paying for it once you're in the French system.
• If you'll turn 65 after you move: the question is whether to sign up at all, and enrollment abroad has a catch. If you're drawing Social Security, Part A starts on its own, and Part B would too if you were still in the US, with you having to actively decline it. Abroad, Part B is not automatic, and you have to elect it through Social Security's international process, with help from the US Embassy or a Federal Benefits Unit if you need it. Social Security should write to you before you turn 65, but if no letter comes, the clock runs anyway. And skipping Part B now counts exactly like dropping it later, with the same penalty waiting if you ever come back.

Either way, be clear on what the money buys before you choose.

Part B pays for none of your care in France: not your doctor, your specialist, your prescriptions, your scans, or any part of a hospital stay. Medicare has a few exceptions for care outside the US, but they cover things like an emergency while driving through Canada or treatment aboard a ship in American waters. None of them describe living in France.

What it does buy is the United States. Routine and emergency outpatient care on trips home stays covered, at any provider that takes Medicare. For someone flying back twice a year, or with grandchildren and aging parents there, that has real value, though probably not several thousand dollars a year of it. Which is why the decision is hard.

The rule that catches retirees

If you drop Part B and later re-enroll, you pay a late enrollment penalty of an extra 10% of the standard premium for each full 12-month period you could have had Part B and didn't. Not a one-time fee. It's added to your premium for as long as you have Part B, which for most people means the rest of your life. Medicare's own example: wait two years, pay 20% more, forever.

The natural next thought is that there must be an exception for living abroad. Several exceptions exist. For most retirees moving to France, none of them apply.

There is a penalty-free Special Enrollment Period, and it hangs almost entirely on current employment. It covers you if you or your spouse are working and covered by an employer's group health plan. Social Security can also treat coverage under a foreign national health system as qualifying, which is where people's hopes rise, since France obviously has one. But that route is an application of the same employment rule rather than a separate escape: Social Security's internal rulebook, at POMS HI 00805.295, wants evidence of the job alongside evidence of the coverage. There's a separate route for people serving in a qualifying international volunteer program, and a set added in 2023 for exceptional conditions like government error or a natural disaster.

None of that describes an ordinary retiree. You'll have the French coverage without the employment underneath it, and the 2023 exceptions turn on events outside your control, which a planned move to France is not.

If you or your spouse still work, or take work abroad later, look harder at these, because the picture changes. For everyone else, the penalty clock runs the entire time you're gone. If you want back in, you wait for the General Enrollment Period, January 1 to March 31, and coverage starts the first of the month after you sign up. (That last part changed in 2023. Plenty of articles still tell you to wait until July. Ignore them.)

Why your years in France hurt Part B but not Part D

Part D. You can't keep it abroad, but Medicare doesn't hold that against you. Because you weren't eligible to enroll while living in France, those months don't count toward a late penalty, and you get a two-month window to rejoin a plan when you move back. The catch is that plans can't see where you lived, so one may assess a penalty on the blank stretch anyway. You'd challenge that with a reconsideration request on a 60-day deadline, with the burden of proof on you years later. So keep your carte de séjour (your French residence permit), your tax notices, and anything CPAM, the local health insurance office, sends you.

Part B. This one you can keep, and Medicare charges you for every month you don't, for the rest of your life.

So Medicare isn't punishing you for leaving. It's charging you for having had a choice.

What keeping Part B actually costs

Part B is priced per person, not per household. For 2026, the standard premium is $202.90 a month each, up from $185.00, with a $283 annual deductible on top. At the standard rate, that's $2,434.80 a year on your own, or $4,869.60 for a couple, all for coverage you'll use on visits home and nowhere else.

That's the floor, and this is where the number can get uncomfortable. Part B premiums are income-adjusted through IRMAA, the income-related surcharge, based on your modified adjusted gross income two years earlier. A higher-income household can pay several times the standard rate. For 2026, married filing jointly:

IRMAA runs on a two-year lookback: your 2026 premium is set by your 2024 return. Think about what that means for someone leaving the US. You sell the house, realize gains to simplify the portfolio, and run Roth conversions before French residency starts. It sounds like good planning, until you realize it is also inflating the income that will price Medicare two years later, when you're in France, being billed $527.50 a month per person for care you can't reach.

Luckily, there is a remedy. If you've had a life-changing event, Form SSA-44 lets you ask Social Security to price your premium off a more recent year. The qualifying events are specific: marriage, divorce, death of a spouse, work stoppage or reduction, loss of pension income, an employer settlement, or the loss of income-producing property, meaning a loss that wasn't your doing. Selling a house isn't one. Neither is a Roth conversion, and there's no catch-all category.

A work stoppage from an earlier year can support using a more recent income year, even when the return driving your surcharge included a Roth conversion. Stop working at 62, convert at 63 and 64, turn 65 facing a premium priced off one of those years, and the retirement is still a qualifying event you can cite.

What Social Security wants is a reduction the work stoppage actually contributed to. If retiring is why your income is lower now, that's a strong claim. If it fell only because a one-off conversion stopped repeating, it's weaker, and an old retirement won't shield every later spike. Approval is fact-specific; the estimate you give has to be your expected income rather than a number chosen to clear the bracket, and Social Security checks it against your actual return later.

Set against all that, French coverage is why people are doing this in the first place. Public coverage plus a mutuelle, the private top-up most French retirees carry, runs roughly €100 to €200 a month per person, as we cover in the healthcare guide.

On paper, paying for Medicare while using French healthcare is irrational. In practice, you're paying for the option to change your mind later, and that option can be worth it.

The bigger risk is Medigap

If that late-enrollment penalty were the only thing at stake, the decision would come down to arithmetic.

Here's an example, using 2026 premiums and holding them flat for simplicity. Take a couple who drop Part B at 68, move to France, and return at 78.

• Over those ten years, they pay no premiums, saving roughly $48,700 between them.
• Coming back a full decade late means a 100% penalty: their Part B premium doubles, for life, which is about $4,869.60 a year extra for the two of them.
• At that rate, it takes about ten years of the higher premium to hand back what they saved, so break-even lands around their remaining life expectancy.

One detail works in their favor. The penalty is charged on the standard premium, not the higher IRMAA-adjusted one, so a high-income couple saves even more by dropping while paying back the same, which tilts the math further toward dropping.

Your own numbers will differ with the ages, the years, and whether it's one of you or two. But the penalty always has this in common: it's a fixed, predictable cost you can calculate in advance and, for most people, absorb. That's what makes it the smaller risk. The one that should worry you is harder to see and harder to undo, and it comes down to a supplemental policy called Medigap.

What Medigap protects, and why you get one shot at it

Original Medicare covers about 80% of your Part B costs and leaves you the other 20%, with no annual limit on what that reaches. Medigap is the private policy that covers the gap, and it's what makes Original Medicare survivable.

You effectively get one chance to buy one. The window is six months, opening the first month you're at least 65 and enrolled in Part B, and Medicare is explicit that it doesn't reopen. Inside it, insurers must sell to you and can't price you on your health. Outside it, they can turn you down, and no federal rule protects someone returning from abroad. So at 78 you apply like anyone else: accepted, charged more for your history, or refused, depending on your health that year, the insurer, and the state you land in. A few states require year-round sales. Most don't.

One quirk cuts the other way. If you never enrolled at 65, your window hasn't opened yet, so it opens whenever you first sign up, at whatever age you've reached. Anyone who left the US before 65 keeps that guarantee in their pocket.

Keeping Part B doesn't hold the window open

This is what trips people up. Paying for Part B through your years abroad spares you the penalty and restores coverage the day you land, but it does nothing for the underwriting question. What protects you is keeping the Medigap policy itself. Those are guaranteed renewable, so an insurer can't drop you for aging or getting sick, only for missed payments, and a policy you hold now is still yours when you return. The catch: Medigap sits on top of Part B, so keeping it means paying for the supplement too, another $100 to $300 a month per person on top of your Part B premium, and for a couple that's two of each. Full reversibility costs close to double what people assume when they start thinking about this.

If an insurer turns you down at 78

Picture the return without a policy in hand. People who come back at 78 come back for a reason, usually a diagnosis or a spouse who died. You apply for Medigap and wait to hear whether anyone will take you.

If nobody will, you still have Part C. Those plans can't screen you on health, so one is available whatever shape you're in, and each caps what you pay in a year for covered Part A and Part B services, which Original Medicare never does: no more than $9,250 in-network for 2026, and some plans set theirs lower. You won't face an unlimited bill. What you give up is freedom of movement, because Part C runs on networks and prior authorization, so the plan gets a say in which specialist and which treatment.

The penalty costs you money. Losing your Medigap protection costs you the freedom to pick your own doctors and hospitals, right at the age when that freedom matters most.

So, keep it or drop it?

One factor is easy to skip past, so start here. The person making this call isn't really you today; it's the older, possibly frailer version of you fifteen or twenty years out, who may want to come home for reasons you can't picture now. If you're part of a couple, there's a sharper version of it: one of you will most likely outlive the other, and a surviving spouse often moves back to be near family. Drop Part B at 68 and you've quietly made that call for whoever is left, twelve years early. Either way, it's a decision worth making on purpose, and for most people it comes down to how settled the move actually is.

Keep paying if you're still early, still tied, or still unsure. Under three years in, permanence isn't something you know yet, whatever you feel about it. The things that pull people back are rarely the things they planned for: a parent who needs help, a stretch in the States that keeps extending, a diagnosis. And if you're already flying home a few months a year, Part B earns its keep every time you land.

Consider dropping once the picture has settled. Five years or more in France, residency or citizenship in hand, no meaningful US ties pulling you back. A healthcare setup you actually trust: registered with CPAM, a mutuelle that covers what you need, doctors who know you. And you've faced the hard what-ifs instead of skipping them: how you'd handle long-term care in Europe, what you'd do if a Medigap insurer turned you down at 78, and, if there are two of you, the surviving-spouse question. If that's you, drop it with a clear conscience.

Nobody can make this call for you, and a bigger balance sheet doesn't settle it either, since it makes the cost easier to carry but also makes dropping more survivable.

The good moves are built out of reversible steps, and these premiums are what reversibility costs. Some years that's a bad deal and you'll resent writing the check. The year you need it, it's the best money you ever spent. You only find out which afterward.
