Review your coverage for life abroad.

Medicare generally pays nothing for care received outside the United States, with a handful of narrow geographic exceptions. Americans living overseas are usually covered instead by the host country’s public health system, entered through legal residence or contributions, by a private international policy, or by both running side by side.

Where Medicare stops at the border

Medicare.gov states that Medicare usually does not cover health care while you are travelling outside the United States. The exceptions are geographic rather than clinical: an emergency arising while you are in the United States, where the foreign hospital is closer than the nearest US one able to treat the condition; travel through Canada without unreasonable delay by the most direct route between Alaska and another US state; and residence in the United States where a foreign hospital is closer to your home than the nearest US one that can treat you, emergency or not. Part B may separately cover a ship’s doctor when the ship is in a US port or within six hours of one. Each is anchored to being in, or beside, the United States — none describes a person whose home is Lisbon or Valencia.

Medigap is the partial exception. The Medicare fact sheet records that standardised plans C, D, E, F, G, H, I, J, M and N pay 80 per cent of billed charges for certain medically necessary emergency care beginning in the first 60 days of a trip, after a $250 deductible for the year, up to a $50,000 lifetime maximum. That 60-day clock is the signature of a travel benefit, not of residence.

The State Department puts it from the other side: Medicare does not cover medical costs outside the United States, and the US government does not pay medical bills abroad. It notes that many locations require payment or a deposit before services, and that air-ambulance evacuation home can cost $20,000 to $200,000.

The Part B penalty, and how it accrues while you are away

Part A arrives automatically for people entitled to Social Security retirement or disability benefits, wherever they live. Part B does not — CMS puts it plainly: you only get Part B if you sign up for it. The initial enrolment period runs seven months, from three months before the month of turning 65 to three months after. For 2026, CMS set the standard Part B premium at $202.90 a month and the Part B annual deductible at $283.

Someone overseas who concludes that premium buys little they can use is reading the coverage rules correctly; what it misses is the price of the decision later. Medicare.gov sets out the mechanism: an extra 10 per cent for each full 12-month period you could have had Part B but did not take it, carried for as long as you hold Part B.

• It counts full 12-month periods, so the figure steps up in whole years, not month by month.
• It attaches to the premium permanently — the doubling rule based on years missed belongs to Part A, not Part B.
• It is measured against the standard premium, which rose from $185.00 in 2025 to $202.90 in 2026, so the same percentage costs more each year.
• Living abroad is not, by itself, a reason the penalty is waived.

Special enrolment periods exist, but each is tied to a defined circumstance: coverage under a group health plan based on current employment, with enrolment available during that coverage or in the eight months after it ends; and the exceptional-conditions periods CMS introduced from 1 January 2023 for declared disasters, health-plan misrepresentation, release from incarceration and termination of Medicaid. Residence abroad is on none of those lists.

Return turns on a distinction easily missed. Medicare.gov gives people who move back to the United States two full months after the month of return — but that window is for joining a Medicare Advantage or Medicare drug plan, which presupposes Part B already in place. First-time Part B enrolment happens in the general enrolment period, 1 January to 31 March, with coverage beginning the first day of the following month. Part D carries a separate penalty of 1 per cent for each month without creditable drug coverage, against a national base beneficiary premium of $38.99 in 2026.

How a host country’s system opens up

European public systems are entered through residence or contributions, not nationality: the European Commission’s Your Europe guidance ties responsibility for cover to economic status and place of residence. The S1 carries an existing entitlement across a border, issued by the institution in the country responsible for a person’s social security, for posted workers, cross-border workers and pensioners. A US Social Security pension generates no S1, because no EU or EEA institution pays it. The European Health Insurance Card covers necessary treatment during a temporary stay, not a move.

Portugal shows the residence route. ACSS, which administers the Portuguese health service, runs the Registo Nacional de Utentes, issuing a permanent número de utente. For an adult foreign citizen, the updated registration needed to enrol in primary care asks for a civil identification document, a tax identification number, a residence authorisation — temporary or permanent — and a full national address; a rental contract or utility bill may stand in where that document is unavailable.

Spain shows the contributory gap and the paid-in route closing it. The Ministerio de Sanidad operates a convenio especial for residents who are neither insured persons nor beneficiaries under Spanish law, EU regulations or a treaty. It requires effective residence in Spain for a continuous period of at least one year before the application, plus registration on a municipal padrón, and costs 60 euros a month under 65 and 157 euros from 65. Outpatient pharmacy, orthopaedic devices, dietetic products and non-urgent transport carry a full patient charge.

Side by side, the work private cover does becomes visible. Spain’s one-year requirement leaves a first-year gap, and inside the convenio outpatient prescriptions fall on the patient. Private policies commonly bridge that interval, pay for what the public route excludes, or buy private-hospital access alongside it — which of those applies depends on country and wording.

Residence applications, and the gap travel cover leaves

Proof of medical cover is a routine part of an application to enter or remain, and it is set nationally, not at European level. The two examples show why no single figure can be quoted as a continental standard: Portugal frames the question around a residence authorisation that unlocks registration, Spain around a year of effective residence before a paid public route opens at all. Sums insured, acceptable insurers and required duration differ country by country.

The gap travel insurance leaves a resident follows from what it is built around: a trip — a departure, a period away, emergency care, and repatriation home. The Medigap foreign benefit makes that assumption explicit by paying only for emergency care beginning in the first 60 days of a trip. A person who has moved has no departure date and no home country in the sense the wording contemplates.

• Routine and preventive care — most of a year’s health spending.
• Ongoing management of a long-term condition, as distinct from an acute episode.
• Maternity and planned procedures, which are scheduled rather than sudden.
• Conditions pre-dating the policy, which trip-based wordings frequently exclude.
• Care sought after a stated day limit has run, whether 60 days or another.

US life and disability policies once the insured lives abroad

Life and disability contracts written in the United States raise a question, not a blanket statement. Some respond normally when the insured moves overseas; others carry residency, travel or occupational provisions that change the outcome, and the only way to know is to read the contract. The terms carrying the weight are identifiable: any residency or foreign-travel clause, and whether it acts as a rating factor, an exclusion, or is silent; how the policy defines the occupation against which disability is measured; whether proof of loss and continued-care requirements can be satisfied by a physician licensed in the host country; and how a claim is paid, in what currency.

Lapse deserves separate attention, because it usually has nothing to do with risk. A policy can end because a premium or grace-period notice went to a US address that no longer receives mail, or because the account funding automatic payment closed during the move. The consequence is the same as a deliberate cancellation, and reinstatement terms are set by the wording, not the circumstances.

Statutory benefits behave more predictably. The Social Security Administration explains that payments generally continue to beneficiaries outside the United States, while Treasury sanctions prevent payments to people in Cuba and North Korea, and payments cannot be sent to people in Azerbaijan, Belarus, Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan or Uzbekistan except under restricted conditions. On the tax side, IRS Publication 502 treats Part B and Part D premiums as medical expenses, deductible on Schedule A only to the extent total medical and dental expenses exceed 7.5 per cent of adjusted gross income.
