Spending Months in Korea? What Medicare Does and Doesn't Cover Abroad

If you are planning a few months in Korea, this is the question to settle before you book the flight.

The short answer is generally no. Original Medicare - Parts A and B - does not pay for care you receive outside the United States. Once you land at Incheon, your Medicare card is not something a Korean hospital can bill.

There are a few narrow exceptions, such as an emergency inside the U.S. where the nearest hospital happens to be across the border. They almost never apply to a trip to Korea.

So the real question is not Medicare itself, but what the coverage you carry on top of it does abroad.

Medigap Plans C, D, F, G, M and N include foreign travel emergency coverage. After a yearly deductible, they pay 80% of the billed charges for medically necessary emergency care outside the U.S.

There are conditions. The emergency has to begin within the first 60 days of your trip, and there is a lifetime limit. Routine checkups and planned treatment do not count.

Plans A, B, K and L do not include this benefit. And if you became eligible for Medicare on or after January 1, 2020, you cannot newly buy Plan C or F. Start by checking the plan letter on your card or policy.

It depends on the plan. Some Medicare Advantage plans add emergency and urgent care outside the U.S. as an extra benefit, and some do not. Those that do set their own limits and claim rules.

So this is not a question anyone can answer from a plan's name. Look in the plan's Evidence of Coverage for 'outside the United States' or 'worldwide,' or call the member services number on the back of your card.

Even when the coverage exists, you will often pay the Korean hospital first and file for reimbursement when you return. Receipts and medical records matter.

A long stay raises a different problem. Medicare Advantage plans are built around members living in the plan's service area, so if you are away for more than six months in a row, the plan can disenroll you.

If that happens, you return to Original Medicare, and the drug coverage that was part of the plan ends with it. The notice goes to your U.S. address, which makes it easy to miss from Korea. Deciding who will open your mail while you are away is part of getting ready.

Some plans offer visitor or traveler programs that extend that period, but these are generally meant for stays elsewhere in the U.S. Ask the plan directly whether anything applies to time in Korea.

If you are thinking about moving back to Korea, this deserves careful thought. Paying a Part B premium you cannot use there can feel like a waste.

You can drop it. The trouble comes if you return to the U.S. and want it back. Living abroad does not qualify you for a Part B Special Enrollment Period, so you can only re-enroll during the General Enrollment Period, January 1 through March 31, and coverage starts the month after you sign up.

On top of that, a late enrollment penalty adds 10% to the premium for each full 12-month period you went without Part B, and it lasts for as long as you have Part B. After a few years in Korea, that adds up.

If you pay a premium for Part A rather than receiving it premium-free, dropping it raises a similar late-enrollment question, so check that separately. Which path fits depends on how likely you are to come back, your age and your health, so do not decide it in one sitting.

Part D plans do not cover prescriptions purchased outside the U.S. If you buy the same medication at a pharmacy in Korea, the plan will not pay you back.

For a long stay, the practical approach is to fill what you can before you leave. How much a plan will release early varies, so once your departure date is set, ask both the plan and your pharmacy.

Keep medications in their original bottles and carry a copy of your prescriptions or a medication list. For what you can bring into Korea, check the Korea Customs Service guidance.

To claim foreign emergency coverage under Medigap or Medicare Advantage, you will need paperwork. However stressful the moment, get the documents before you leave the hospital.

Korean hospitals can often issue an English diagnosis certificate and English itemized receipts on request. There may be a fee, but it is far easier than translating Korean documents after you return.

Contact the plan or insurer as soon as you reasonably can. Claim deadlines and required documents vary, and asking while you are still in Korea can save a second trip back to the hospital.

It comes down to three things: what your coverage does abroad, how long you will be away, and whether your coverage picks back up cleanly when you return.

Do this a month or two before you leave. If you will be in Korea in the fall, also check whether your trip overlaps the Annual Enrollment Period, October 15 through December 7. Reviewing next year's plan from Seoul is not easy.
