So, you’ve hit retirement, packed up your bags, and you’re thinking about spending your golden years somewhere a little sunnier, a little cheaper, or maybe just a little more exciting than back home. Whether it’s sipping wine in Portugal, relaxing on Costa Rica's beaches, or exploring Italy's hills, more and more Americans are considering retiring abroad. But before you grab that passport and one-way ticket, there’s one big question to answer: What happens to your Medicare when living abroad?
Let's walk you through what you can expect—and how you can prepare—if you plan to live outside the United States after age 65.
What Medicare Covers (and Doesn’t Cover) Outside the U.S.
Let’s get right to the point: Original Medicare (Parts A and B) generally does not cover healthcare services outside the United States.
There are a few very rare exceptions. For instance, if you’re traveling between Alaska and another U.S. state and have a medical emergency requiring you to go through Canada, Medicare might help. Or if you’re on a cruise and the ship is within six hours of a U.S. port and has a U.S. doctor onboard, there may be some limited coverage. But for the most part, if you’re living or traveling abroad, don’t count on Medicare to foot the bill for doctor visits, prescriptions, or hospital stays.
This is one of the biggest shocks for many retirees. After paying into Medicare for decades, it can be hard to accept that it won’t follow you overseas. But it’s true—and that means planning is essential.
Should You Keep Your Medicare Anyway?
Even though Medicare doesn’t cover you abroad, you may still want to keep your Part A coverage. The reason is simple: Most people don’t pay a premium for Part A since they’ve paid Medicare taxes through their work history. So keeping it doesn’t cost you anything extra in most cases. It also means if you ever return to the U.S.—whether for a short visit or permanently—you’ll have your hospital coverage ready to go.
Part B, however, is a little trickier. That’s the part of Medicare that covers doctor visits, outpatient care, and some preventive services—and it comes with a monthly premium. In 2025, that premium is $185 per month for most people, though it can be higher if your income is above a certain threshold.
If you’re moving abroad permanently and are sure you won’t need coverage in the U.S. for a long time, you might be tempted to drop Part B to avoid the monthly cost. But there’s a catch: If you decide to return to the U.S. and re-enroll in Part B later, you could face a late enrollment penalty, and you may have to wait until the next General Enrollment Period (which runs from January 1 to March 31 each year). That means you could be without coverage for months—and when you do get it back, you’ll likely pay more for life.
Many expats choose to keep Part B “just in case.” Yes, it costs money, but it also gives you peace of mind if something unexpected brings you back home.
What About Medicare Advantage and Part D?
If you’re enrolled in a Medicare Advantage plan (Part C) or a Part D prescription drug plan, you’ll probably need to drop that coverage if you move out of the country. Private insurance companies offer Medicare Advantage plans and are usually tied to specific service areas within the U.S. Once you’re out of that area for more than a few months, the plan can disenroll you.
The same goes for Part D. Prescription drug plans are also regional; you must live in their service area to stay enrolled.
If you plan to move abroad temporarily, talk with your plan provider about your intentions and how long you’ll be gone. Some plans allow for short absences but will boot you off if you’re gone too long.
What If You Come Back to the U.S.?
Life can be unpredictable. Maybe you planned to retire in Belize, but after a few years, you realize you miss the grandkids too much and decide to return. If you dropped your Medicare, you’ll have to go through the re-enrollment process—and that’s where things can get complicated.
As I mentioned earlier, there are penalties for late enrollment. For Part B, the penalty is 10% for every 12-month period you were eligible but didn’t sign up. That penalty gets added to your premium—for life.
For Part D, the late penalty is calculated based on how long you went without coverage, and it also sticks with you permanently.
The best way to avoid these headaches is to stay enrolled in Medicare if you can afford it, or at least speak with a Medicare expert before making any final decisions.
Final Thoughts: Plan Ahead and Stay Informed
Retiring abroad can be a dream come true, but don’t let that dream become a healthcare nightmare. Medicare won’t follow you overseas, so it’s up to you to plan wisely. Keep your Part A, think carefully before dropping Part B, and always have a solid plan for how you’ll get medical care in your new country.
Most importantly, don’t make these decisions alone. Talk with someone who understands Medicare inside and out—someone who can look at your situation, travel plans, budget, and health—and help you make the best call.
Healthcare is too important to leave to guesswork, especially in retirement. So before you leave the U.S., take the time to make sure your health—and your future—is covered.
