Health Cover Abroad: What Happens to Your US Insurance

For Americans, healthcare is the emotional core of any move abroad — equal parts hope (“I’ve heard it’s affordable”) and terror (“what if I’m uncovered?”). Both instincts are right: coverage abroad is usually far cheaper than US healthcare, and the transition is where people get caught exposed.

First, the hard facts about your US coverage

• Employer plans and ACA marketplace plans generally provide little to no routine coverage outside the US — and you typically can’t keep ACA coverage without US residency anyway.
• Medicare pays essentially nothing abroad. Whether to keep paying Part B for re-entry protection is its own decision: Medicare and moving abroad.
• Travel insurance is not a substitute — it covers emergencies on trips, not life abroad. The difference matters enough that we wrote it up separately: travel vs expat health insurance.

What replaces it: the three layers of European cover

Layer 1: Private expat/visa insurance (your entry ticket)

Most long-stay visas require proof of private health insurance covering you locally. Comprehensive private cover for a healthy 60-something in Portugal or Spain commonly costs a fraction of an unsubsidised US premium — often a few thousand dollars a year rather than tens of thousands. Insurers range from the big international names to strong local carriers. Age limits and pre-existing-condition rules vary, so shop before you’re in a hurry.

Layer 2: The public system (arrives with residency)

Many countries open their public healthcare to legal residents — sometimes immediately, sometimes after a qualifying period or by paying into the system. Public systems handle the serious, expensive things well; the trade-off is waiting times for non-urgent care.

Layer 3: Private top-up (the popular combo)

Many expats settle into public-system membership plus a modest private policy for fast specialist access and private hospitals — often the best value in healthcare anywhere.

The transition trap

The dangerous window is between your last day of US coverage and your first day of solid coverage abroad. Close it deliberately: line up the expat policy to start on arrival (visa applications usually force this anyway), consider short bridge cover for the moving weeks, and never let the gap ride on “we’ll sort it when we land.” Timing this is a standard line on the Financial Relocation Roadmap.

Spain’s authorised-insurer rule

Spain’s non-lucrative visa is the strictest common case. The consulate wants health insurance from an insurer authorised in Spain, with no waiting period, no co-payments and no coverage cap — and travel insurance is rejected outright. Each condition matters on its own: an international plan with a modest excess fails the “no co-payments” test; one with an annual limit fails the “no cap” test, however generous the limit.

The practical route is a Spanish-market policy written for the visa, kept through the application and the first year. Bending a worldwide plan to fit the list usually costs more time than the policy costs money.

Portugal’s two-stage paperwork

Portugal asks for two different things at two different moments, and people over-buy for the first and under-prepare for the second. At the consulate, for a D7 or D8 application, travel insurance with medical and repatriation cover is what’s asked for. At the residence-permit stage with AIMA, you need health insurance or proof of coverage by the national health service.

So a full expat policy is not needed on day one, but it — or public registration — must exist by the time your residence appointment comes round. Buy the travel policy for the flight; have the real policy quoted and ready to start before you land.

Medicare and Medigap once you leave

Neither follows you. Medicare’s exceptions for care outside the United States are narrow and none of them describes living in Lisbon; Medigap’s foreign-travel benefit is a trip benefit for US residents, capped for life, not residence cover for expats. Whether to keep paying for Part B, what the late-enrolment penalty costs if you don’t, and which kinds of foreign coverage let you delay without one are worked through in Medicare and moving abroad.

Age caps and the underwriting clock

Private international plans are usually renewable for life once you’re in, but many will not start a policy for a new customer above a certain age, and the cap differs by insurer and country. If you are in your sixties and planning a move, the cheapest health-insurance decision you will ever make is applying while you are still under every insurer’s ceiling.

The same clock runs on pre-existing conditions: a condition that develops after the policy starts is covered; the identical one diagnosed the month before you applied is excluded or loaded. Buy before the scouting trip becomes a move.

Why the premiums are lower: the OECD numbers

The premium gap is arithmetic, not a marketing trick. On the OECD’s purchasing-power-adjusted figures for 2024, the United States spends $14,823 per person on health. Switzerland spends $9,927, Germany $9,584 and the Netherlands $8,696. Portugal comes in at $5,375, Spain at $5,349 and Italy at $5,337.

Southern Europe, in other words, spends about 64% less per person than the US, and the northern three roughly a third to 40% less. An insurer pricing a policy in Spain is pricing against Spanish hospital bills, which is why “a few thousand dollars a year” is not too good to be true.

Budgeting honestly

Healthcare abroad isn’t free — it’s priced like a utility instead of a crisis. Budget for premiums, modest out-of-pockets, dental/vision, and the occasional private specialist. For most American households the total still lands dramatically below US costs — run your own numbers with the free calculator and the full picture in retiring in Europe.
