3 health insurance myths that catch Americans off guard the moment they move abroad
Move abroad and your insurance card doesn’t stop working the way you’d expect — it just stops being useful in the exact moment you need it. Most people spend months researching visas and flights and give health coverage a vague “I’ll figure it out.” That’s exactly where these three myths sneak in, and all three get expensive fast.
1. Medicare will still cover me if I get sick overseas
This is the one that trips up retirees the hardest, especially anyone planning a slow-travel life abroad. Original Medicare Parts A and B pay almost nothing outside the United States. There’s a genuinely narrow exception for emergency care in Canada if you’re traveling between Alaska and another state and the nearest hospital happens to be Canadian — yes, really, that specific.
Medicare Advantage plans are tied to a US service area, so care abroad is typically off the table there too, though a handful of 2026 plans have started bolting on optional “travel” add-ons. Already have a Medigap policy? Some of those cover 80% of foreign emergency care after a deductible, up to a lifetime cap. That’s a real safety net, but it’s something you pay extra for on top — not a feature Original Medicare hands you for free.
2. I can just keep my ACA marketplace plan while I’m gone
Marketplace plans are built around one assumption: you live in a state. To buy or keep a Healthcare.gov plan, you actually have to reside in one of the 50 states or DC. Move abroad, and that eligibility ends, full stop.
Even in the rare case someone manages to stay technically enrolled, the plan’s network is US-based. It pays doctors and hospitals inside the country, not the clinic down the street in Lisbon or Chiang Mai. You’d be paying a premium every month for a safety net that literally can’t reach where you’re standing.
Psst — thinking about actually doing this? I put everything I know about leaving the U.S. for good into one no-fluff guide: visas, jobs, country picks, the works — grab it here.
3. Dropping Part B while I’m away is basically free until I need it again
Not quite. Cancel Medicare Part B and move back to the US later, and you can get hit with a late enrollment penalty: 10% added to your premium for every 12-month stretch you went without it. That penalty is permanent, not a one-time fee you shake off after a year.
There’s a real exception worth knowing, though. If you were living abroad when you first became eligible for Medicare and hadn’t started collecting Social Security yet, you can enroll penalty-free within three months of moving back. The same protection applies if you had coverage abroad through an employer plan — you get an eight-month window to sign up once that coverage ends.
So what actually covers you instead
Most working-age expats skip US-based coverage entirely and buy international insurance instead, which honestly makes this whole problem disappear. Budget nomad plans like SafetyWing’s Nomad Insurance Essential tier run around $45 to $50 a month, while fuller expat health plans — SafetyWing Remote Health, for one — start closer to $250 a month depending on age and coverage level.
Not cheap. But a lot more honest than assuming a US plan quietly follows you across an ocean and picks up the tab wherever you land.
Which one of these would’ve caught you off guard? If it’s the ACA one, you’re in good company — that’s the myth that trips up the most people.
