International Health Insurance

International health insurance is health coverage built for people who are outside their home country's health system, whether for a two-week trip or a permanent move. It exists because domestic US health plans generally stop at the border: most employer and marketplace plans cover only emergency care abroad, if that, and pay nothing for routine care overseas, while Medicare ordinarily covers no care outside the United States at all. A person who will spend meaningful time abroad, and who cannot rely on a national health system where they are going, typically needs a policy designed for the purpose.

The category splits by how long the person will be away. Travel-medical insurance covers a defined trip and is meant for tourists, students on short programs, and business travelers; it pays for emergencies and often includes medical evacuation. Expatriate health insurance is an ongoing plan for someone living abroad, closer to a normal health plan in that it covers routine and preventive care as well as emergencies, and can often be held for years.

Medicare's near-total exclusion of foreign care is the single most important fact here, because so many people assume the opposite. Medicare generally does not pay for health care received outside the United States and its territories. The exceptions are narrow and situational: an emergency in the United States where the nearest hospital that can treat the condition is across the border in Canada or Mexico; an emergency while traveling the most direct route through Canada between Alaska and another US state; a case where a foreign hospital is closer to a US home than the nearest US hospital that can treat the condition; and care aboard a ship within US territorial waters. Outside those situations, a retiree who moves abroad and keeps only Medicare has, in practical terms, no coverage where they live. Some Medicare Advantage plans and some employer retiree plans add limited foreign coverage, but original Medicare on its own does not travel.

Some Medigap policies fill a sliver of the gap, but only a sliver. Standardized Medigap plans that include the foreign-travel emergency benefit cover 80 percent of the cost of qualifying emergency care that begins during the first 60 days of a trip abroad, after a deductible and subject to a lifetime maximum. That is genuinely useful for a short emergency early in a trip, but the 60-day limit, the emergency-only scope, and the lifetime cap mean it is not a substitute for a real international plan for anyone spending extended time overseas.

Choosing between travel-medical and expatriate coverage is mostly about duration and what care is needed. Travel-medical policies are inexpensive and easy to buy per trip, but they cover emergencies rather than ongoing or pre-existing conditions and end when the trip does. Expatriate plans cost more and are underwritten more like ordinary health insurance, but they cover the routine, chronic, and preventive care a resident actually uses, and they do not lapse at the end of a trip. Medical evacuation coverage, which pays to transport a patient to adequate care or home, is a common and worthwhile feature of both, because an evacuation can cost more than the treatment itself.

The tax and mandate angle is narrower than it once was, but worth stating. The Affordable Care Act's individual "shared responsibility" requirement to carry minimum essential coverage is still on the books, but the federal penalty for not carrying it has been zero since 2019, so lacking US coverage while abroad no longer carries a federal tax cost. In addition, US citizens and residents who qualify as living abroad, broadly those who meet the foreign earned income exclusion's residence or presence tests, are treated as having minimum essential coverage for the months they qualify, so the requirement does not force an expatriate to buy a US plan they cannot use. A handful of states run their own coverage mandates, which is a separate question from federal law.

The practical process is to match the product to the stay: for a short trip, buy a travel-medical policy for the dates away; for a move abroad, buy an expatriate plan that covers routine and chronic care in the destination; and in either case confirm whether medical evacuation is included. A retiree should not assume Medicare provides any coverage at the destination.

A hypothetical example. Gerald, age 68, retires from the United States to Thailand and keeps his Medicare, assuming it will cover him. It does not: original Medicare pays nothing for his care in Thailand, and none of the narrow foreign exceptions apply to someone simply living there. His old Medigap policy would cover only 80 percent of an emergency in the first 60 days of a trip, after a deductible and up to a lifetime cap, which does nothing for the routine care he needs as a resident. So Gerald buys an expatriate health insurance plan that covers his primary care, prescriptions, and hospital care in Thailand, with medical evacuation added in case he needs treatment the local system cannot provide. He keeps his Medicare paid up only so that he can use it again if he returns to the United States, where it works normally.

International health coverage is close to a necessity for extended time abroad, so the framing is the trade-offs between the products, not whether to have one.

Why it matters and what it does

• It fills a gap most people do not know exists, since US plans and especially Medicare cover little or nothing abroad.
• Travel-medical policies are cheap and easy to buy for a defined trip and usually include medical evacuation.
• Expatriate plans cover the routine, chronic, and preventive care a resident abroad actually uses, not just emergencies.

The limits and trade-offs

• Travel-medical coverage handles emergencies, not ongoing or pre-existing conditions, and ends with the trip.
• Expatriate plans cost more and are medically underwritten, so coverage and price depend on health history.
• Medigap's foreign-travel benefit is emergency-only, capped, and limited to the first 60 days of a trip, so it cannot stand in for real coverage.
• Keeping Medicare while abroad pays for care you cannot use there, though it preserves coverage for any return to the United States.
