Medicare Does Not Follow You Abroad

*Medicare will not cover you overseas, but dropping it triggers a permanent penalty. Here is the actual math on keeping or dropping Part B when you move abroad.*

*Panama City, Day 10. We are moving apartments this week, on purpose, which is a story for another issue. Today’s issue is about a decision that lands on every American who retires abroad, usually after it is too late to think clearly about it.*

A reader planning a move to Portugal asked a question last week that sounds simple: “Do I keep paying Medicare when I leave?” The honest answer is that Medicare gives every retiree expat a two-sided bill and lets you pick which side to pay. In 2026, keeping Medicare Part B costs $202.90 a month, about $2,435 a year, for insurance that will almost never pay a claim while you live overseas. Dropping it starts a penalty meter that adds 10 percent to your premium for every full 12 months you go without it, and that surcharge is permanent when you return. There is no option labeled “pause while abroad.” The system was not built with you in mind, and understanding why it works this way is the difference between a planned cost and an expensive surprise.

The misconception: “I moved, so I am done paying”

Most people assume health coverage works like a utility. You move out, you cancel the account, and if you move back you open a new one. Medicare is not built that way, and the assumption quietly costs returning expats thousands.

Start with what Medicare actually covers overseas: essentially nothing. Outside the United States, Medicare pays only in a handful of narrow situations, such as a medical emergency in the US or on a cruise ship within six hours of a US port, or transiting Canada between Alaska and another state, or when a foreign hospital is closer to your US home than the nearest American one. None of those describe a retiree living in Cuenca, the Algarve, or Panama City. For practical purposes, a Medicare card is a piece of US-only plastic the moment your plane leaves the ground.

So dropping Part B looks obviously rational. The problem is that Medicare is not a subscription. It is a risk pool with a fence built around it, and the fence is the late enrollment penalty.

The reality: how the penalty architecture works

Three rules interact here, and each one raises the stakes on the others.

First, the premium. Part B in 2026 costs $202.90 a month at the standard rate. Higher earners pay income-adjusted surcharges on top. Part A, by contrast, is premium-free for almost everyone who worked at least 10 years in the US, which is why the standing advice is to keep Part A regardless of where you live. The keep-or-drop question is a Part B question.

Second, the penalty. For each full 12-month period you could have had Part B and did not, your future premium rises by 10 percent of the standard amount. The penalty is not a one-time fee. It attaches to your premium for as long as you have Part B, which for most people means for life. Go abroad for five years, drop Part B, and re-enroll on return, and you pay 150 percent of whatever the standard premium is in that future year. At today’s rate that is over $100 a month in pure surcharge, roughly $1,200 a year, every year, for the rest of your life.

Third, the enrollment calendar. Employees with group coverage get a special enrollment period when their employer plan ends. Living abroad earns you no such window. Unless you qualify through a working spouse’s employer coverage or certain volunteer service, a returning expat waits for the general enrollment period, January 1 to March 31, with coverage starting the month after signup. Return in April uninsured and you can stand exposed for the better part of a year before Part B switches on.

Why is the system built this way? Because Part B is insurance, and insurance only works if healthy people cannot wait until they are sick to buy in. The penalty is an actuarial fence against adverse selection. It was never designed to punish expats. It simply does not care that your reason for leaving the pool was a good one.

The strategic insight: this is a one-variable math problem

Once you see the two costs clearly, the decision compresses into a single question: how long will you be gone?

Keeping Part B costs about $2,435 per year of absence at 2026 rates. Dropping it costs roughly 10 percent of the future standard premium, per year of absence, every year after you return, plus the gap-exposure risk of the general enrollment calendar. The break-even depends on how many years you expect to draw on Medicare after coming back. A 66-year-old who leaves for three years and returns for twenty will likely pay more in lifetime penalty than three years of premiums would have cost. A retiree who is confident the move is permanent, who intends to live and die abroad on local insurance that costs a fraction of US coverage, is paying $2,435 a year for nothing and can rationally let Part B go.

The honest complication is that “permanent” is doing heavy lifting in that sentence. Health is the most common reason expats repatriate, and the person most likely to need US care on return is exactly the person the penalty prices hardest. People who understand this system make the decision with a written assumption about return probability, not a feeling. Some split the difference: they keep Part B as a paid option on returning home, and treat the premium as the cost of keeping that door open, while carrying local or international private coverage for actual care abroad. In many countries that private coverage for a healthy person in their sixties costs less than Part B itself.

What this means in practice for Americans

If you are 6 to 18 months from a move, three actions follow from the mechanics. Decide on Part B with a number, not a mood: write down your honest probability of returning and your expected years back in the US, and run both columns. Keep Part A unless you have a specific reason not to; it is free and it preserves hospital coverage for US visits that turn into emergencies. And price local and international health insurance in your destination before you leave, because that quote is the third number the decision needs. Retirees on the standard $2,071 Social Security check should notice the proportion here: Part B alone is nearly 10 percent of that income, which is exactly why this decision deserves an hour of arithmetic rather than a default.

One more calendar note: if you plan to keep contributing to a Health Savings Account in your final US working years past 65, the interaction between Medicare enrollment and HSA rules has its own trap, which is the subject of today’s paid issue.

Key takeaways

Medicare essentially does not cover care outside the United States. Part B in 2026 costs $202.90 a month, and keeping it abroad means paying for coverage you cannot use. Dropping it triggers a 10 percent lifetime penalty per full 12-month gap, and returning expats get no special enrollment period, only the January-to-March general window. Part A is free for most people and worth keeping regardless. The keep-or-drop decision is a math problem with one dominant variable, your expected years back in the US, and it should be made on paper before departure, not discovered at re-entry.
