Medicare for U.S. Expats Living Abroad: Coverage, Costs, and Enrollment
Medicare pays for almost nothing when you live abroad. It does not reimburse a doctor in Lisbon or a pharmacy in Mexico City, and the Part B premium buys you access to care back in the United States and little else. That holds whether you are already enrolled and wondering if the premium is worth keeping, or approaching 65 overseas and deciding whether to sign up at all. Medicare.gov lists the 2026 standard Part B premium at $202.90 per month, $2,434.80 per year, with a $283 annual deductible before Original Medicare pays anything.
Four things decide what you should do:
- Whether you qualify for premium-free Part A: If you do, it is free to hold and carries no late penalty.
- Whether you expect to move back to the United States: The largest factor, because the real cost of dropping Part B is the price of getting back in.
- Whether anyone in your household still works: Coverage from a current job changes your enrollment rights entirely.
- What your U.S. tax return said two years ago: Higher income adds a surcharge.
Below: what each part covers overseas, what it costs, when you can enroll from abroad, and what happens if you come home.
Does Medicare Cover Healthcare Overseas?
Medicare generally pays nothing for care you receive outside the United States, including prescriptions from a local pharmacy. The program is built around U.S. providers billing a U.S. system. Three narrow exceptions exist, and none help a senior living abroad full-time who sees a local doctor.
The Coverage Does Not Follow You
Neither Part A nor Part B reimburses routine care where you live, and Part D never covers drugs bought abroad. This is what most people get wrong before they move, and it is why a national health system, a private international plan, or both is the usual answer overseas. Our guide to health insurance while living abroad compares those options, and international versus expat plans explains the difference.
The left column is why you paid in. The right is why the premium feels like money for nothing once you have moved.
Three Exceptions Exist and They Are Narrow
Medicare.gov names three: care on a cruise ship within six hours of a U.S. port, a foreign hospital closer than the nearest U.S. one able to treat you during an emergency while you are in the United States, and care on a direct route through Canada between Alaska and another state. None describes ordinary life overseas.
Who Is Eligible When You Turn 65 Abroad?
Living in another country does not affect whether you qualify for Medicare, but it does affect whether anyone signs you up. Eligibility depends on your work record and your citizenship or residency status, exactly as it would at home. Enrollment is what changes, because the automatic process does not reach you.
Nobody Enrolls You Automatically Overseas
If you are already receiving Social Security at 65, enrollment normally happens without you having to ask. That does not apply abroad, and the Social Security Administration’s procedures go further, telling staff to make a particular effort to stop beneficiaries overseas from enrolling in Part B by mistake. If you are abroad and do nothing, you will generally not be enrolled. Check your award letter to see which it is.
Your First Window Opens Before You Turn 65
Your Initial Enrollment Period runs seven months: the three before the month you turn 65, that month, and the three after. Sign up in the first three, and Part B starts the month you turn 65. Sign up in your birthday month or the three that follow, and it starts the following month. This is the one window where nothing is held against you. Let it close without job-based coverage behind you, and the late penalty starts building.
Premium-Free Part A Is the Easy Decision
If you or your spouse has enough covered work history, Part A costs nothing. You can add it any time after age 65; coverage can be backdated up to 6 months; and there is no late enrollment penalty for premium-free Part A. For most seniors abroad, taking Part A and leaving Part B as the open question is the sensible start. Without that work record, it costs $311 or $565 a month, which changes the calculation.
What Do the Parts Cost in 2026?
Part B costs $202.90 a month in 2026, with a $283 annual deductible. Part A is free for most people who qualify based on their work record. One side of the decision costs nothing; the other runs about $2,435 a year for coverage you will rarely use overseas.
The Standard Premium Rose in 2026
| Part B cost | 2025 | 2026 |
|---|---|---|
| Standard monthly premium | $185.00 | $202.90 |
| Annual cost at the standard rate | $2,220.00 | $2,434.80 |
| Annual deductible | $257 | $283 |
CMS confirms the following year’s premium each November, so no figure for the next year exists yet. Anything circulating before that is a projection.
Higher Incomes Pay an Added Surcharge
Above certain income levels, you pay more. The Social Security Administration sets this income-related adjustment from the return you filed two years earlier.
| Income on your return from two years ago, single | Married filing jointly | Added to the monthly premium |
|---|---|---|
| Above $109,000 to $137,000 | Above $218,000 to $274,000 | $81.20 |
| Above $137,000 to $171,000 | Above $274,000 to $342,000 | $202.90 |
| Above $171,000 to $205,000 | Above $342,000 to $410,000 | $324.60 |
| Above $205,000 to below $500,000 | Above $410,000 to below $750,000 | $446.30 |
| $500,000 or more | $750,000 or more | $487.00 |
A large IRA distribution or a property sale can lift you a tier two years later, so it’s worth timing as part of your retirement planning abroad.
Should You Enroll While Living Abroad?
The answer depends mostly on whether you expect to live in the United States again. The worry underneath this is usually not the monthly cost, but being old, unwell, and uninsured somewhere down the line. That is the right thing to weigh, and it is why the cost of getting back in matters more than the premium you save.
Keeping It Buys Access You Will Rarely Use
At $202.90 a month, you are paying for doctor visits in a country you do not live in. Some seniors keep it because they travel back regularly, or because a treatment they expect to need is only available at home. Paying out of pure caution is how people spend $24,000 over a decade on coverage they never use.
Dropping It Saves About $2,435 a Year
The savings are immediate, and if you are receiving Social Security, you will see them reflected in your monthly payment. What you give up is the right to re-enter at the standard price, and that cost should drive the decision more than the premium does.
One exception: if you or your spouse has a group health plan based on current employment, you can wait to add Part B when it ends, with no penalty.
What Is the Penalty for Skipping Part B?
You pay an extra 10 percent of the standard premium for each full 12-month period you could have had Part B and did not. For most people, the increase is permanent, so work it out before you decide.
Every Missed Year Adds Another 10 Percent
Medicare’s own illustration is two full years out: a 20 percent penalty, which, at the 2026 rate, would raise the premium from $202.90 to $243.50 per month. Five years abroad means a 50 percent penalty, adding $101.45 a month. The percentage climbs with each year out, so the number to know is how many full years you expect to be away.
The Break-Even Point Is Around Ten Years
Five years without Part B saves about $12,174 at the 2026 rate. Re-enrolling then carries a 50 percent penalty at $101.45 per month, so the savings run out roughly 10 years after you re-enroll, not 10 years after you drop it. Two things stretch that further. Only full 12-month periods count, so five years and eleven months still earn 50 percent. And the penalty is calculated on the standard premium, so anyone paying an income surcharge sets a much larger saving against the same penalty and stays ahead far longer.
Drug Coverage Has Its Own Separate Penalty
Part D runs a second penalty on the same principle. Go 63 days or more without creditable drug coverage, and you pay an extra 1 percent of the national base beneficiary premium per month of the gap, $38.99 for 2026. That surcharge lasts as long as you hold drug coverage, even if you switch plans.
What Happens If You Return to the U.S.?
If you dropped Part B, you cannot switch it back on when you land. Without a Special Enrollment Period, the only route back in is the General Enrollment Period (January 1 to March 31), and coverage begins the month after you sign up.
Only Job-Based Coverage Opens an Eight-Month Window
The eight-month Special Enrollment Period is real and narrower than it sounds. CMS grants it for one situation: group health coverage based on current employment, yours or a spouse’s. A foreign national health system, a private international plan, COBRA, and former-employer retiree coverage do not create it. Coverage through a foreign employer’s own group plan is worth confirming with CMS before you rely on it. International volunteer service carries its own six-month period. Since January 2023, there have been case-by-case periods for exceptional conditions, but there is no general allowance for having lived overseas.
October 15 Does Nothing for Part B
The window that opens every October 15 and closes December 7 only lets you join, drop, or switch an Advantage plan or a drug plan. It cannot add Part B, and neither can the two-month window you get for those plans after moving back.
The gap is the part people miss. Land back in April, and your next chance is the following January, with coverage starting that February. Returning in March instead can be the difference between a few weeks without Part B and most of a year, so put this calendar beside the tax consequences of returning.
How Do You Sign Up From Another Country?
Enrollment from abroad is handled by a Federal Benefits Unit at a U.S. embassy or consulate, not by a local Social Security office. To add Part B on its own, you file Form CMS-40B.
Part A Comes First, and There Is No Country Field
The form cannot be used at all unless you already hold Part A, and its address block includes City, State, and ZIP, with no field for a country.
The international volunteer question in Section 2 is the one most expats skip, and it is there because volunteer service abroad has its own enrollment period. The coverage start date choice at the bottom is closed unless someone is still working, so the calendar decides your start date, not you.
The Premium Comes Out of Your Benefit Payment
If you are collecting Social Security abroad, the premium is deducted from your monthly payment, including when it goes to a foreign bank account. If you are not drawing benefits yet, Medicare bills you every three months.
Are the Rules Different in Mexico or Canada?
No country has its own arrangement with Medicare. The program pays nothing in Mexico, nothing in Canada, nothing in Portugal, and nothing in Thailand, and the three exceptions above turn on where the care happens, not where you live. What differs by country is what the local system will give you and how long you must live there first.
What Changes Is the Local System, Not Medicare
Some countries allow a foreign resident to purchase public healthcare coverage after a waiting period. Others require permanent residency first, or exclude new arrivals over a certain age. A few offer no realistic public option, leaving private cover as the only route. Our guides to retiring in Mexico and retiring in Canada set out what each offers, and the lower-tax retirement destinations differ widely. One thing that does not help here: totalization agreements coordinate Social Security contributions and benefits, never Medicare.
Do Advantage Plans and Medigap Work Abroad?
Neither replaces local cover. An Advantage plan covers you only inside its service area, and moving overseas puts you outside it, though some plans add a limited worldwide emergency and urgent care benefit worth checking before you rely on it. Medigap needs you to hold both Part A and Part B before an insurer will sell you a policy. Leaving the service area opens a two-month window to pick a different Advantage plan, counted from the month you move, or the month before if you tell the plan first. Do nothing and you revert to Original Medicare, the normal outcome for someone moving abroad, with no penalty.
A Lapse in Part B Closes the Medigap Door
Your six-month Medigap guaranteed-issue window starts on the first month you are both 65 or older and enrolled in Part B, and within it, an insurer generally must sell to you regardless of your health history. Re-enrolling at 72 opens a fresh six months, but any condition you developed in between is on the record by then. Outside that window, no federal rule requires an insurer to sell you a policy, and one that does can price it on your health.
Does Your Tax Return Change What You Pay?
Yes, and for anyone still working abroad after 65, it works in a way that the Social Security Administration’s own materials do not spell out. The surcharge is based on the return you filed two years earlier, so figures from a return you have forgotten determine next year’s premium.
Excluded Foreign Income Still Counts
The statute defines the income subject to the surcharge as adjusted gross income determined without regard to sections 135, 911, 931, and 933, plus tax-exempt interest. Section 911 covers both the foreign earned income exclusion and the foreign housing exclusion. Income you excluded on your return is added back for this purpose. The Social Security Administration’s premium page, its program manual, and Form SSA-44 all describe the figure as adjusted gross income plus tax-exempt interest and never mention foreign income, which leaves those descriptions incomplete for an expat.
Neither Way of Cutting Your U.S. Tax Cuts This
This matters only if you are still working abroad past 65. Americans with foreign wages usually lower their U.S. tax in one of two ways: the foreign earned income exclusion, which keeps those wages off the return, or the foreign tax credit, which offsets U.S. tax against foreign tax you already paid. Either route can bring your U.S. tax bill to zero and leave the Medicare surcharge exactly where it was, because the credit keeps wages in your income, and the exclusion adds them back. Form SSA-44 is the one thing that does move the surcharge, and only once your income has genuinely dropped, which is why stopping work is on its list of accepted life-changing events.
Frequently Asked Questions
Yes, at any time, and seniors abroad often do, because it pays almost nothing where they live. The cost is a 10% penalty for each full 12-month period you are out, which is added to your premium permanently if you re-enroll.
Part A is free for most people who qualify on their own or a spouse’s work record. Part B is optional and costs $202.90 a month in 2026. If you are enrolled and receiving Social Security, it is deducted from your monthly payment until you cancel it.
Only if you are enrolled at the time. Part A covers hospital care from the moment you arrive if you kept it. Part B covers doctor and outpatient care only while enrolled, and you cannot add it mid-year without a Special Enrollment Period.
Premium-free Part A can still be added later with no penalty. Part B is where the cost sits: every full year you could have held it and did not adds 10 percent to the premium if you eventually sign up. Once your Initial Enrollment Period has closed, and without job-based coverage, you can generally only sign up between January 1 and March 31.
The Decision Depends on Whether You Return
For a senior settled abroad for good, Part B costs real money and returns very little, and dropping it is a reasonable call. For anyone who might come home, the penalty and the closed Medigap window make it far cheaper to keep than to rebuild. Premium-free Part A falls outside that argument and is worth taking either way, so most people abroad can maintain some Medicare coverage without paying for it.
Underneath it sits a tax question, because the same income that funds your retirement sets your premium two years later and shapes what you owe on a U.S. return filed from abroad. Given that a foreign pension, a Social Security benefit, and a Form 1040-SR can all be in the same year, Greenback’s accountants have deep expertise in how those pieces fit together.
Retirement income, handled from start to finish
Medicare figures here reflect 2026 amounts confirmed by CMS and the Social Security Administration as of publication. Premiums, deductibles, and thresholds are set annually, and no premium has been announced for the following year. The ten-year comparison holds the premium flat at the 2026 rate for illustration.
