International Health Insurance for American Expats: Costs, Coverage, and the Medicare Gap

# International Health Insurance for American Expats: Costs, Coverage, and the Medicare Gap

A 68-year-old retiree in Lisbon slips on wet cobblestones and fractures her hip. The surgery and five-day hospital stay cost roughly €14,000 in Portugal's private system. She paid Medicare payroll taxes for 41 years. Medicare pays none of it — not the ambulance, not the surgeon, not a single night in the hospital — because she was standing on the wrong side of a border when it happened. That is not a loophole. It is how Medicare is designed to work, and it is the single fact that should shape every American's health coverage plan before they relocate abroad.

This article breaks down what Medicare actually covers overseas, why the Part B enrollment decision is one of the most consequential and least understood choices retiring expats make, and what private international health insurance costs in 2026.

Why Medicare Stops at the Border

Medicare defines "the United States" narrowly: the 50 states, Washington D.C., Puerto Rico, the U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands. Everywhere else — France, Mexico, Thailand, even a long layover in Toronto — falls outside Medicare's coverage area, according to [Medicare.gov's fact sheet on coverage outside the United States](https://www.medicare.gov/publications/11037-medicare-coverage-outside-the-united-states.pdf).

There are four narrow exceptions where Original Medicare will pay a foreign provider: a medical emergency inside the U.S. where a foreign hospital is genuinely closer than the nearest American one; emergency treatment in Canada while traveling without unreasonable delay between Alaska and another state; non-emergency care at a foreign hospital that is closer to your U.S. residence than any domestic option; and care received on a cruise ship while it is within six hours of a U.S. port. Outside those situations, Part A and Part B pay nothing.

Medicare Part D compounds the problem for retirees managing chronic conditions: prescriptions filled at a pharmacy abroad are not covered under any circumstances, though Part D does cover ACIP-recommended vaccines — including travel vaccines like yellow fever and Japanese encephalitis — if you get them in the U.S. before you leave, per [Medicare.gov](https://www.medicare.gov/publications/11037-medicare-coverage-outside-the-united-states.pdf).

The Part B Decision That Costs Retirees Thousands

The costliest mistake expats make isn't buying the wrong travel policy — it's mishandling Medicare Part B enrollment. Here's the mechanism.

Medicare's Special Enrollment Period (SEP), which lets you delay Part B without penalty, only applies if you or your spouse have **current employment-based group health coverage** — an active employer's plan, not retiree coverage, not a foreign national health system, and not private insurance you bought yourself, according to [Medicare Interactive](https://www.medicareinteractive.org/understanding-medicare/health-coverage-options/medicare-and-living-abroad/medicare-coverage-for-those-who-live-permanently-outside-the-united-states) and [AARP](https://www.aarp.org/medicare/does-medicare-cover-me-outside-the-us/). An American retiree enrolled in France's carte vitale system or a private Cigna Global policy does not qualify for the SEP. If you skip Part B at 65 without qualifying coverage, you're accumulating a penalty even while living somewhere Medicare couldn't help you anyway.

The penalty is permanent: Medicare adds 10% to your Part B premium for every full 12-month period you were eligible but didn't enroll, for as long as you have Part B, per [Medicare.gov](https://www.medicare.gov/basics/costs/medicare-costs/avoid-penalties). The standard Part B premium in 2026 is $202.90 a month. Someone who spends four years abroad past their Initial Enrollment Period without qualifying coverage would face a 40% permanent surcharge — an extra $81.16 every month, indefinitely, on top of the standard premium, the moment they re-enroll back in the U.S.

Higher earners face an additional layer: Medicare's Income-Related Monthly Adjustment Amount (IRMAA) uses your tax return from two years prior. Retirees whose 2024 modified adjusted gross income exceeded $109,000 (single) or $218,000 (joint) pay elevated Part B premiums in 2026, with total monthly premiums at the highest income tier reaching $689.90, according to figures drawn from [CMS.gov's 2026 Medicare Parts A & B premium fact sheet](https://www.cms.gov/newsroom/fact-sheets/2026-medicare-parts-b-premiums-deductibles).

Part A is a separate calculation. About 99% of beneficiaries get it premium-free because they have 40 quarters (roughly 10 years) of Medicare-covered work history, per [NCOA](https://www.ncoa.org/article/medicare-parts-a-and-b-costs/). If you qualify for premium-free Part A, there's no cost to enrolling and keeping it as a safety net for care during visits home, even though it pays nothing overseas. If you don't have 40 quarters, Part A costs $311 a month in 2026 with 30–39 quarters of work, or $565 a month with fewer than 30 — money that, again, buys you nothing while you're living abroad.

The upshot: expats aging into Medicare face a genuine tradeoff — pay roughly $2,435 a year for Part B coverage that's useless in their country of residence, purely to avoid a permanent penalty, or decline it and gamble that they won't need to re-enroll later at a much higher lifetime cost. There's a narrow safety valve: returning permanently to the U.S. triggers a two-month Special Enrollment Period starting the month you move back, per [Medicare Interactive](https://www.medicareinteractive.org/understanding-medicare/health-coverage-options/medicare-and-living-abroad/medicare-coverage-for-those-who-live-permanently-outside-the-united-states).

Medigap and Medicare Advantage Don't Close the Gap

Medigap Plans C, D, F, G, M, and N include a foreign travel emergency benefit, but it's built for travelers, not residents. It covers 80% of emergency care costs after a $250 annual deductible, capped at a $50,000 lifetime limit, and only applies if the emergency begins within the first 60 days of a trip abroad, according to [Boomer Benefits](https://boomerbenefits.com/foreign-travel-for-people-on-medicare/). Someone who has relocated permanently isn't on a "trip" in any meaningful sense, and Medigap policies are state-regulated products generally tied to maintaining U.S. residency — carriers can question claims, and guaranteed-issue rights, from an expat who's clearly living abroad full-time.

Medicare Advantage plans are worse for this purpose: most restrict coverage to in-network U.S. providers entirely, with little to no emergency benefit outside the country. None of these products are a substitute for local health coverage in your country of residence.

What International Health Insurance Actually Costs

This is where most expats end up: buying a private international health insurance policy, often called International Private Medical Insurance (IPMI). Costs vary enormously by age, destination, and whether the plan includes U.S. coverage (which raises the price sharply, since U.S. medical costs are the highest priced input in any global network).

Individual premiums for comprehensive plans typically run from $500 to $15,000 a year, with the average landing around $2,517 to $3,020 annually before or after discounts, per [William Russell's 2026 cost data](https://www.william-russell.com/international-health-insurance/how-much-does-expat-health-insurance-cost/). Age drives the steepest swing: one widely cited example shows a 25-year-old paying roughly €96 a month for inpatient coverage with a €450 deductible, while a 65-year-old on the identical plan pays around €370 a month — a 285% increase for the same benefits, according to [April International](https://www.april-international.com/en/long-term-international-health-insurance/guide/how-much-does-international-health-insurance-cost). Budget nomad-style plans, like SafetyWing's, start around $63 per four-week period for people aged 18–39, but these typically exclude routine care, pre-existing conditions, and often the U.S. itself unless you pay an add-on.

The major carriers expats compare — Cigna Global, Allianz Care, GeoBlue (now part of Blue Cross Blue Shield Global Solutions), IMG Global, and Bupa Global — differ mainly in network size, deductible options, and whether maternity, mental health, and dental are bundled or optional, per [Expat Financial's 2026 rankings](https://expatfinancial.com/top-3-global-health-insurance-companies-for-expats/). Because premiums climb steeply with age, locking in a policy earlier, and shopping renewal terms every year rather than assuming auto-renewal is competitive, meaningfully affects lifetime cost.

The ACA Marketplace Isn't a Backup Plan

Some expats assume they can fall back on healthcare.gov if private international coverage feels too expensive. It generally doesn't work that way. Marketplace plans are built around U.S.-based provider networks, and premium tax credit eligibility depends on U.S. tax residency and household income between 100% and 400% of the federal poverty level, according to the [IRS](https://www.irs.gov/affordable-care-act/individuals-and-families/eligibility-for-the-premium-tax-credit) and [KFF](https://www.kff.org/faqs/faqs-health-insurance-marketplace-and-the-aca/help-paying-marketplace-premiums-the-basics/who-is-eligible-for-marketplace-premium-tax-credits/). Even where someone technically qualifies, a plan priced around a U.S. hospital network is not usable for a stomach bug in Chiang Mai. The federal individual mandate penalty has been $0 since 2019, but a handful of states — Massachusetts, New Jersey, California, Rhode Island, and D.C. — still fine residents who lack coverage, which only matters if you're still considered a resident of one of those states for tax purposes.

Practical Takeaways

• **Before you move**, buy an international health policy and confirm whether it includes medical evacuation — Medicare, Medigap, and ACA plans generally exclude medevac entirely, and a single air ambulance can cost $50,000 or more.
• **If you're turning 65 abroad**, contact the Social Security Administration (1-800-772-1213) or your embassy's Federal Benefits Unit before your Initial Enrollment Period closes, and decide deliberately whether to take Part B, rather than defaulting into a penalty by inaction.
• **Keep premium-free Part A** if you qualify — it costs nothing and gives you a safety net for care during trips back to the U.S.
• **Get quotes from at least three insurers annually** — Cigna Global, Allianz Care, GeoBlue, IMG, and Bupa Global all price differently by age band and region, and premiums escalate fast after 60.
• **Read the U.S.-coverage clause carefully.** Many international plans exclude the United States by default or charge a steep add-on for it, which matters if you plan to visit family regularly.
• **Document your Part B decision.** If you decline coverage while abroad, keep records of why, since proving you lacked qualifying employer coverage (or didn't need to) becomes relevant if you ever dispute a penalty.

Next Steps

Medicare was built for people living inside U.S. borders, and it does that job well. It was never designed to follow retirees to Lisbon, Chiang Mai, or Mexico City, and pretending otherwise is what leads to five- and six-figure medical bills or permanent premium penalties. Before you relocate, get a firm quote from at least two international insurers, call the Social Security Administration to understand your specific Part B timeline, and decide — in writing, for your own records — whether you're keeping, delaying, or declining each piece of Medicare. The cost of an hour on the phone now is far lower than the cost of a wrong assumption discovered in an emergency room overseas.
