Medicare Coverage Abroad: What Expats Need to Know

# Medicare Coverage Abroad: What Expats Need to Know

In 2026, a retiree living in Lisbon will pay **$202.90 every month** for Medicare Part B — and Medicare will not pay a cent toward the doctor's visit she has down the street. That figure is the new standard Part B premium for 2026, up $17.90 from $185.00 in 2025, according to the Centers for Medicare & Medicaid Services (CMS). For the roughly hundreds of thousands of Medicare-age Americans who live outside the United States, that monthly bill buys coverage they usually cannot use where they live.

The rules here are unusually rigid, and the mistakes are expensive and often permanent. Below is what the program actually pays for abroad, what it costs to keep, and the decisions that can save — or cost — you thousands.

The Core Rule: Medicare Stops at the U.S. Border

Original Medicare — Part A (hospital insurance) and Part B (medical insurance) — generally **does not cover health care services or supplies you get outside the United States**, per Medicare.gov. There is no claims process for a routine appointment in Mexico City, a prescription in Bangkok, or a planned surgery in a Madrid clinic. You pay out of pocket, and you cannot bill Medicare for reimbursement.

The definition of "United States" matters here, because it is broader than the 50 states. For Medicare's purposes, the U.S. includes the **50 states, the District of Columbia, Puerto Rico, the U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands** (Medicare.gov). Care in any of those locations is treated as domestic. Care anywhere else on the planet is "outside the United States" — and outside coverage.

The Narrow Exceptions

Medicare describes a short list of situations in which Original Medicare *may* pay for medically necessary inpatient hospital, doctor, and ambulance services in a foreign hospital. According to Medicare.gov, these are:

1. **You're in the U.S. when an emergency happens**, and a foreign hospital is closer than the nearest U.S. hospital that can treat your illness or injury.
2. **You're traveling through Canada by the most direct route** between Alaska and another U.S. state, without unreasonable delay, when an emergency occurs — and a Canadian hospital is closer than the nearest U.S. hospital that can treat it.
3. **You live in the U.S. and a foreign hospital is closer to your home** than the nearest U.S. hospital that can treat your condition — whether or not it's an emergency.

Notice what these exceptions have in common: each assumes you are based in the United States and that a foreign hospital simply happens to be the closest option. None of them describes an American who has *moved abroad*. If you live in Portugal full-time, none of these three doors is open to you for your day-to-day care.

There is one more carve-out worth knowing if your travel involves the water. Medicare may cover medically necessary services you receive aboard a ship **within the territorial waters adjoining the land areas of the United States**. But Medicare will not pay for care on a ship that is **more than six hours away from a U.S. port**, per Medicare.gov. A mid-Atlantic crossing is uncovered; a coastal cruise may not be.

What You Still Pay: The 2026 Numbers

Here is the part that frustrates expats most. Even though Original Medicare won't follow you abroad, the premiums don't stop unless you act.

• **Part A** is premium-free for most people — those with at least 40 quarters (10 years) of Medicare-covered employment. If you qualify for premium-free Part A, there's usually little reason to drop it, since it costs you nothing to keep.
• **Part B** carries the standard **$202.90 monthly premium in 2026** (CMS), and a separate **annual deductible of $283** for 2026, up from $257 in 2025. Higher-income beneficiaries pay more than the standard amount through income-related adjustments.

That Part B premium is the crux of the expat dilemma: you can keep paying roughly **$2,435 a year** for coverage you rarely use where you live, or you can drop Part B and risk a penalty that can follow you for the rest of your life. Which brings us to the most important decision on this page.

The Part B Trap: Dropping It Can Cost You for Life

Many expats reason, sensibly, that paying $202.90 a month for unusable coverage is a waste — so they drop Part B. That can be the right call. It can also be a costly one, because of how the **late enrollment penalty** works.

If you don't sign up for Part B when you're first eligible and later enroll without qualifying for a Special Enrollment Period, you'll pay a penalty of **10% of the standard premium for each full 12-month period you could have had Part B but didn't** — and you pay it for **as long as you have Part B**, according to Medicare.gov. Wait five years and the surcharge is 50%, added to your premium every month, permanently.

The trap for expats is that **foreign health coverage and most foreign employment do not count** as the kind of current-employer group coverage that earns you a penalty-free Special Enrollment Period when you return. In other words, having excellent insurance through a job in Germany generally won't shield you from the U.S. penalty the way a job in Ohio would. CMS has added "exceptional conditions" Special Enrollment Periods in recent years that can help in specific circumstances, but you should not assume you qualify.

When you move back to the United States, there is a window to re-enroll, but the rules are technical and the consequences are lasting. **Before you drop Part B, confirm your exact situation with the Social Security Administration** — which handles Medicare enrollment — rather than relying on assumptions. The math on dropping Part B should weigh the premiums you'd save against the penalty you might owe if you return, multiplied by your life expectancy after re-enrolling.

Part D and the Pharmacy Problem

Medicare prescription drug coverage doesn't travel either. **Medicare drug plans (Part D) don't cover prescription drugs you buy outside the United States**, per Medicare.gov. For most expats, this is less of a crisis than it sounds, because medications are often dramatically cheaper abroad when paid out of pocket — but it does mean a Part D premium is usually money spent on a benefit you can't use overseas. Part D also carries its own late enrollment penalty, calculated separately from Part B, so the same "keep it or drop it" analysis applies.

Medigap's Foreign Travel Emergency Benefit

The one piece of the Medicare system that *does* reach across borders is Medigap — Medicare Supplement Insurance — but only for emergencies, and only for travelers rather than permanent residents.

According to Medicare.gov, Medigap **Plans C, D, F, G, M, and N** include a foreign travel emergency benefit. These plans pay **80% of the billed charges for certain medically necessary emergency care outside the U.S.**, with these conditions:

• A **$250 annual deductible** before the benefit kicks in.
• A **$50,000 lifetime limit** on foreign travel emergency coverage.
• The emergency care must **begin during the first 60 days of your trip**, and only when Medicare doesn't otherwise cover it.

Read those limits carefully. This is travel-emergency protection, not a residency plan. The 60-day window means it's built for vacations and short trips, not for someone who has relocated permanently. And a $50,000 lifetime cap can be exhausted by a single serious hospitalization. Medigap is a useful backstop for an expat who still travels in and out of the U.S., but it is not a substitute for local or international health insurance where you live.

Medicare Advantage Abroad

Medicare Advantage (Part C) plans are sold by private insurers and bundle Parts A and B, often with extra benefits. Some plans offer worldwide emergency or urgent care coverage as a supplemental benefit — so check your specific plan's documents if you have one.

But two structural problems make Medicare Advantage a poor fit for long-term expats. First, these plans are built around U.S. provider networks you can't use abroad. Second, and more important: a Medicare Advantage plan can **disenroll you if you're outside its service area for more than six months**. Move overseas indefinitely on a Medicare Advantage plan and you risk losing it — and then needing to navigate enrollment rules to get back into Original Medicare.

Practical Takeaways and Action Items

If you're approaching 65 abroad, or already living overseas on Medicare, work through this checklist:

• **Keep premium-free Part A.** If you qualify (40+ quarters of work), there's almost no downside to keeping it — it costs nothing and covers U.S. hospital stays when you visit.
• **Run the Part B math before dropping it.** Compare the $202.90/month premium ($2,435/year in 2026) against the potential 10%-per-year lifetime penalty if you return and re-enroll. Get your specific answer from the Social Security Administration, not a forum.
• **Buy real coverage where you live.** Local national health systems, private local insurance, or an international/expat health plan are what will actually pay your bills abroad. Medicare is not that plan.
• **Use Medigap only as a travel backstop.** If you keep a Plan C, D, F, G, M, or N, know its foreign benefit caps out at $50,000 lifetime, pays 80% after a $250 deductible, and covers only emergencies in your first 60 days abroad.
• **Don't count on Medicare Advantage overseas.** Confirm whether your plan offers worldwide emergency coverage, and remember the six-month-out-of-service-area disenrollment rule.
• **Document your timeline.** If you plan to return to the U.S. eventually, keep records of your coverage and employment abroad in case you later need to establish eligibility for a Special Enrollment Period.

Conclusion: Your Next Steps

The single most important thing to understand about Medicare abroad is that it is, with narrow exceptions, a U.S.-only program — and the costliest mistakes come from misjudging the enrollment rules, not the coverage rules. Keep cheap or free Part A, make a deliberate and informed decision about Part B, and secure separate insurance for the country where you actually live.

To act on this:

1. **Read the source pages directly.** Start with Medicare's "Travel Outside the U.S." coverage page and the "Medicare Coverage Outside the United States" fact sheet on Medicare.gov.
2. **Call the Social Security Administration** to confirm how dropping or keeping Part B affects *your* future re-enrollment and penalty exposure — these rules turn on individual facts.
3. **Price local and international health plans** in your destination country before you assume Medicare has you covered.
4. **Revisit the decision annually**, since premiums (like the 2026 increase to $202.90) and enrollment rules change each year.

Get the enrollment decisions right once, and you avoid a surcharge that could follow you for decades. Get them wrong, and a few years of "saving" on premiums can cost far more when you come home.
