Medicare does not cover healthcare received outside the United States — with three very narrow exceptions. If you're planning to retire abroad in 2026, you need to make a clear Medicare decision before you leave: which parts to keep, which to drop, and what international insurance replaces what Medicare can't cover. Getting this wrong can cost you thousands in re-enrollment penalties or leave you uninsured during a medical emergency.
This guide covers exactly what happens to your Medicare coverage when you move abroad, how to avoid the most expensive mistakes, and what international health insurance options are available for retirees in 2026.
Does Medicare cover you when living abroad?
No — with three narrow exceptions. Medicare Part A and Part B generally do not cover healthcare received outside the 50 states, Washington D.C., Puerto Rico, the US Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands. The three exceptions are: (1) Emergency care while in Canada when traveling by the most direct route between Alaska and the continental US. (2) Care on a ship within US territorial waters (6 nautical miles of a US port). (3) Emergency care at a foreign hospital that is closer to you than the nearest US hospital (applies only in certain border situations). None of these exceptions apply to retirees living permanently abroad.
What to do with each Medicare part when retiring abroad
Medicare Part A — Keep it (it's free for most people)
Most Americans who paid Medicare taxes for at least 40 quarters (10 years of work) pay $0 for Medicare Part A. There is no logical reason to drop it — it costs nothing and provides coverage whenever you're back in the US (visiting family, receiving complex specialist care, etc.). Keep Part A regardless of where you retire.
Medicare Part B — Keep it (penalty risk if you drop it)
Part B is the tricky one. The 2026 standard premium is $185.00/month (higher if your income exceeds $106,000 single/$212,000 married, per the IRMAA tables). If you drop Part B while abroad and later return to the US and re-enroll, you'll pay a 10% premium penalty for each 12-month period you were without coverage — permanently, for the rest of your life. On a $185/month premium, dropping Part B for 5 years costs an extra $92.50/month forever when you re-enroll. Most financial planners recommend keeping Part B active even while abroad, treating it as insurance against returning to the US.
Medicare Part C (Medicare Advantage) — Drop it
Medicare Advantage plans are offered by private insurers as an alternative to Original Medicare. Almost all Medicare Advantage plans do not cover care outside the US (some offer limited emergency-only international coverage). If you're retiring abroad, disenroll from your Medicare Advantage plan and return to Original Medicare (Part A + Part B) — this can be done during the Annual Enrollment Period (October 15 – December 7) or through a Special Enrollment Period triggered by moving. You'll then purchase international health insurance separately for your overseas care.
Medicare Part D (Drug coverage) — Consider dropping
Medicare Part D covers prescription drugs in the US. If you're abroad long-term, you'll purchase drugs locally (typically far cheaper — a 30-day supply of common medications like statins or blood pressure drugs runs $5–15 in most retirement destinations vs. $30–150 US retail). The Part D late enrollment penalty is 1% of the 'national base beneficiary premium' for each month without coverage — less severe than Part B but still worth considering. If you plan to return to the US within 5 years, it may be worth keeping a low-premium Part D plan. If you're retiring abroad indefinitely, dropping it is often financially rational.
What international health insurance replaces Medicare abroad
International health insurance for retirees varies widely. The key types are: Comprehensive International Plans (cover hospitalization, outpatient, specialist, drugs, medical evacuation — $80–400/month depending on country and age), Local Country Plans (Ecuador's IESS, Colombia's EPS — cheaper, limited to one country, $80–200/month), and Travel Insurance (wrong product for long-term living — caps at 180 days, limited chronic disease coverage, don't use as primary coverage).
| Insurance type | Monthly cost (65yo) | Covers | Best for |
|---|---|---|---|
| Comprehensive international | $150–450/mo | Global or regional, all care types | Most retirees; mobile lifestyle |
| Local country plan | $80–200/mo | One country, comprehensive | Committed long-term in one country |
| US-compatible plan | $300–600/mo | US + international | Frequent US visitors |
| Travel insurance | $50–150/mo | Short trips, emergencies only | NOT for permanent residency |
Medicare planning timeline for retirees moving abroad
- 12 months before move: Research international health insurance options for your target country. Get quotes from Cigna Global, Allianz Care, Pacific Cross (SE Asia), and AXA International.
- 6 months before: If you have Medicare Advantage (Part C), plan to disenroll during the next Annual Enrollment Period and return to Original Medicare.
- 3 months before: Drop Part C effective January 1 (or your SEP trigger date). Finalize international health insurance plan.
- At the move: Keep Part A and Part B active. Drop Part D only if financially rational (use the Part D Late Enrollment Penalty calculator). Activate international health insurance.
- Ongoing: Review international insurance annually. Keep Medicare active. Plan for any complex care that might require returning to the US.
The cost comparison: Medicare + international insurance vs. US-only coverage
A 65-year-old retiree in the US who keeps Medicare Part A + Part B ($185/month) and purchases a Medigap Plan G ($150–250/month, national average) plus Part D ($30–70/month) spends $365–505/month on healthcare coverage, plus copays and deductibles. The same retiree abroad, keeping Medicare Part A + Part B ($185/month) and adding a comprehensive international plan ($80–250/month depending on destination), spends $265–435/month — with actual care that is 40–70% cheaper when used. The math strongly favors the overseas option.
Countries with the best healthcare for US retirees (Medicare context)
The countries where US retirees typically get the best combination of Medicare context (keeping Part A/B active, using international plan for day-to-day care) and overall healthcare quality are: Portugal (EU public system + private supplement), Thailand (JCI hospitals at fraction of US prices), Colombia (top Latin American hospitals + affordable private insurance), and Panama (US-trained doctors, English widely spoken, JCI facilities). Countries where the Medicare-plus-international model is most financially advantageous: Vietnam, Ecuador, Albania, Georgia — where even international insurance is $80–150/month for a 65-year-old.
