If You Retire in China Long Term, Should You Keep Medicare?

In the previous article, which asked whether someone should become a U.S. citizen before retiring in China, one issue was left for a separate discussion.

Suppose someone worked in the United States for decades, became eligible for Medicare after age 65, and then plans to spend retirement living in China long term.

Should Medicare still be kept?

At first, the answer may seem obvious.

If Medicare generally cannot be used in China, why keep paying Part B premiums every month while living there for ten years?

But consider the opposite question.

What if health deteriorates ten years later and the person wants to return to the United States for treatment?

What if Part B is needed again at that point?

Will reenrollment be immediate?

Will there be penalties?

And what if the person eventually decides to move back to the United States permanently?

That makes Medicare a particularly unusual part of cross-border retirement planning.

The money paid today may not be buying medical care in China today.

A large part of its value may instead be buying:

the option to reenter the U.S. healthcare system more smoothly ten years from now.

Start with the basic fact: Medicare generally does not work in China

This is the starting point for every calculation.

Medicare’s rules are clear: except in limited circumstances, Medicare generally does not pay for medical services received outside the United States.

For Medicare purposes, the United States includes the 50 states, the District of Columbia, Puerto Rico, the U.S. Virgin Islands, Guam, the Northern Mariana Islands, and American Samoa.

China is obviously not included.

So a 70-year-old retiree may have both Medicare Part A and Part B, but if that person lives long term in Shanghai, Beijing, Guangzhou, Chengdu, or another Chinese city, routine care received at local hospitals generally cannot simply be billed to Medicare.

That means:

Medicare cannot serve as the primary health insurance system for someone retiring long term in China.

A separate plan is still needed for medical care in China.

That may involve Chinese public health insurance, private insurance, paying out of pocket, or some combination of those options. The best arrangement depends on factors such as household registration, prior insurance participation, age, and local rules, and deserves a separate discussion.

But the U.S. side still matters.

That is because Medicare is not one single insurance plan.

For cross-border retirees, the most important distinction is often between Part A and Part B.

Part A and Part B should not automatically be treated as one decision

Most people who worked long enough in the United States qualify for premium-free Part A at age 65.

Part A mainly covers inpatient hospital care, certain skilled nursing facility services, hospice care, and some home health services.

If Part A does not require a monthly premium, there is usually little financial reason to think of it as something that needs to be actively canceled simply because someone moves to China.

In practical terms, the more difficult decision for most retirees is not Part A.

It is:

Part B.

Part B covers physician services, outpatient care, tests, medical equipment, and many other non-hospital services.

The key difference is that Part B requires a monthly premium.

In 2026, the standard Part B premium is:

$202.90 per month.

Higher-income retirees may pay more because of IRMAA.

That makes the cost very tangible.

If someone lives in China for ten years and has little practical use for Part B during that period:

$202.90 × 12 months = $2,434.80 per year

Using the 2026 premium as a simple static example:

10 years would equal:

$24,348.

Actual future premiums may rise, so the true ten-year cost could be higher.

Is it worth spending more than $24,000 on coverage that may be rarely used during those ten years?

That is one of the central questions for cross-border retirees.

Why are people still reluctant to drop Part B?

Because Part B has an important feature:

It can be easy to drop, but not necessarily easy or inexpensive to get back later.

If someone does not enroll in Part B when first eligible, or later drops Part B and does not have coverage that protects a delayed enrollment, reenrolling later may trigger a late enrollment penalty.

Under current rules, the Part B penalty generally adds:

10% of the standard Part B premium for each full 12-month period of delay.

And this is not usually a one-time charge.

The higher premium can continue for as long as the person has Part B.

For example, Medicare’s 2026 illustration shows that someone who enrolls two full years late and does not qualify for a Special Enrollment Period may face a 20% penalty.

With the 2026 standard Part B premium of $202.90:

20% is about $40.58.

That would bring the monthly premium to roughly:

$243.50.

And the surcharge can continue year after year.

That is why “I cannot use it in China anyway, so I will just cancel Part B” is not as simple as it first appears.

What happens if you live in China for ten years and then return?

Consider a more realistic example.

Suppose someone decides at age 70 to retire in China.

The person already has premium-free Part A and is paying the monthly Part B premium.

The plan is:

Live in China for ten years.

At age 80, health may have changed. A spouse may have died. Adult children in the United States may want the parent to move back.

There are two broad approaches.

The first:

Keep Part B for the entire ten years.

Using the 2026 standard premium as a static illustration, ten years would cost about $24,348.

For much of that time, Part B may provide little practical value in China.

But when the person returns to the United States at age 80, Part B is still active.

Physician visits, outpatient care, testing, and other covered services can continue under whatever Medicare rules apply at that time.

The second approach:

Drop Part B at age 70 and reenroll when returning to the United States at age 80.

This saves ten years of premiums.

But if no qualifying coverage or Special Enrollment Period applies, reenrollment may trigger a lasting late enrollment penalty.

There is also a timing problem.

A person generally cannot always say:

“I am flying back to the United States tomorrow, so I will restart Part B next week.”

If no other Enrollment Period applies, the person may need to use the General Enrollment Period, currently January 1 through March 31 each year. Under current rules, coverage generally begins the month after enrollment.

So the real question is not:

“Is $24,348 expensive?”

It is:

“How much am I willing to pay to make it easier to use Medicare again if I return to the United States at age 80?”

That is no longer just an insurance-premium question.

It is the price of preserving a future option.

But “ten years abroad” does not automatically mean a 100% penalty

This point needs care.

People often hear “10% for every year” and immediately conclude:

“If I live in China for ten years, I will be penalized 100%.”

That is too simplistic.

Part B late enrollment penalties depend on whether the person was expected to have Part B during the period in question, whether qualifying coverage existed, whether a Special Enrollment Period applies, and the person’s exact enrollment and residency circumstances.

A person who already had Part B and later voluntarily drops it may not be in exactly the same position as someone who was living abroad at age 65 and never enrolled in Part B in the first place.

Medicare guidance distinguishes among different overseas-residency situations.

For example, someone who already receives Social Security and has Part A but does not take Part B at age 65 may later have to wait for an enrollment period and could face a late enrollment penalty.

But there are other situations in which a U.S. citizen living abroad first becomes eligible to enroll in Part B after returning to establish U.S. residence and may avoid a late enrollment penalty if enrollment is handled on time.

So:

“Years abroad × 10%” is not a universal formula.

Before dropping Part B, the most important question is not to calculate the penalty yourself.

It is to confirm:

Given my current Medicare status, what exact reenrollment rule would apply if I cancel Part B now and return years later?

That is much better to know before canceling than ten years afterward.

Having health insurance in China may not protect you from a Part B penalty

Another common assumption is:

“I will have health insurance in China, so I am not really uninsured. That should protect me when I rejoin Part B later.”

Medicare does not simply ask:

“Did you have any health insurance at all?”

The most common Special Enrollment Period protection for delaying Part B comes from a group health plan based on current employment of the person or spouse.

That distinction matters greatly for retirees.

Ordinary Chinese public medical insurance or a privately purchased Chinese health policy does not automatically become the kind of current-employment group health coverage Medicare recognizes for this purpose merely because it is “health insurance.”

Most retirees in China are no longer working.

So it is risky to assume:

“I have insurance in China, so I can always add Part B later without consequences.”

Eligibility for a Special Enrollment Period has to be determined under Medicare’s specific rules.

Returning to the United States also raises Medicare Advantage and Part D questions

Even if someone keeps Part A and Part B while living in China, that does not mean every part of Medicare will simply remain unchanged.

Medicare Advantage and Part D involve another layer of rules.

Medicare Advantage plans and Medicare drug plans generally operate within defined service areas. Enrollment usually requires living in the plan’s service area.

So someone who truly moves to China long term should not assume that a Medicare Advantage plan purchased in a U.S. county or state will simply remain fully usable abroad in the same way as Part A and Part B status.

There is, however, an important rule for people who later return.

Someone who has been living outside the United States and then moves back to live in the United States may qualify for a Special Enrollment Period to join a Medicare Advantage plan or Medicare drug plan.

Under current rules, that opportunity generally lasts through the two full months following the month of return.

So when someone comes back after years in China, there may be several separate decisions:

Part A and Part B;

Original Medicare versus Medicare Advantage;

and Part D prescription drug coverage.

They should not all be treated as one single “Medicare switch.”

Part D should not be forgotten either

Long-term retirees in China also need to think about Medicare Part D.

Part D has its own late enrollment penalty.

Under current rules, if someone goes 63 days or more after becoming eligible without Medicare drug coverage or other creditable prescription drug coverage, a penalty may apply when Part D is later added.

That penalty can continue as part of the monthly Part D premium.

So someone planning to retire in China should also ask:

Do I currently have Part D?

Should I keep it while living in China?

If I drop it, would my prescription coverage in China count as creditable coverage under Medicare rules?

How would I rejoin Part D if I later return to the United States?

These questions depend on the specific coverage involved and should be checked individually.

Medigap creates another “it may not be easy to buy back later” problem

Someone using Original Medicare may also have Medigap.

Medigap works differently from Part B.

The most important Medigap enrollment window generally begins when someone first enrolls in Part B and lasts six months.

That window is especially valuable.

After it closes, buying Medigap later may involve fewer options, higher prices, or medical underwriting depending on state law and the insurer’s rules.

Some Medigap policies also provide limited foreign travel emergency coverage.

But that should not be mistaken for comprehensive long-term health insurance for someone living permanently in China.

So if someone is considering dropping not only Part B but also an existing Medigap policy, another question should be asked before making the decision:

If I return to the United States ten years from now, will I still be able to buy comparable Medigap coverage on acceptable terms?

That may matter more than the premium savings today.

So should Part B be kept or not?

At this point, the answer cannot simply be “yes” or “no.”

The most important factor is not Medicare itself.

It is:

How likely are you to return to the United States for long-term living or major medical treatment later?

Consider someone who is very certain that:

retirement will remain permanently in China;

medical arrangements in China are stable;

there is no plan to move back to the United States;

even major illness would be treated in China;

and the person fully understands the consequences of dropping Part B.

For that person, continuing to pay for Part B that is rarely usable in China may become increasingly difficult to justify.

But consider another retiree:

All the children live in the United States;

the person plans to spend only the healthier years in China;

there is a strong possibility of returning to live with children after age 80;

major cancer treatment, complex surgery, or other advanced care might still be sought in the United States;

or the person simply does not know where life will be ten years from now.

For this person, the monthly Part B premium should not be viewed only as:

“Insurance I am not using today.”

It also buys something else:

the ability to return to the United States and reenter the Medicare healthcare system with fewer obstacles.

Immigration status also changes the meaning of the Medicare decision

This brings the discussion back to the three paths examined in the previous article.

If someone keeps a green card and genuinely continues to maintain life in the United States after retirement, keeping Medicare may be relatively easy to understand because the United States remains part of everyday life.

If someone gives up the green card, keeps Chinese citizenship, and truly settles in China permanently, continuing Part B becomes a more difficult calculation.

At that point, not only has healthcare shifted to China, but the ability to return to the United States for permanent residence has itself become a separate immigration issue.

Being eligible for Medicare does not by itself create the right to live permanently in the United States.

If someone becomes a U.S. citizen before retirement, the picture is different.

No matter how many years are spent in China, the person can later return to live in the United States.

For that individual, keeping Part B may have more obvious option value because there is always a secure legal right to return and use the U.S. healthcare system.

But that still does not mean every U.S. citizen living abroad should keep Part B.

If someone is certain that future medical care will remain in China, the monthly premium is still a real expense.

Immigration status changes the value of the option.

It does not make the decision automatically.

The real calculation is not about today. It is about age 80

One of the biggest mistakes in cross-border retirement planning is using today’s health to make decisions for the person you will be ten years from now.

At age 70, someone may feel healthy.

Medical care in China may be convenient and affordable.

The $202.90 monthly Part B premium can look like money being wasted.

But when deciding whether Medicare is worth preserving, the more relevant person to imagine is not your 70-year-old self.

It is:

your 80-year-old self.

Will your spouse still be alive?

Where will your children be?

Will you still be able to live independently?

If cancer, heart disease, stroke, or the need for complex surgery develops, where would you want treatment?

If independent living is no longer possible, would you enter long-term care in China or move back to live near children in the United States?

If you suddenly decide to return, can healthcare coverage begin when you need it?

At that point, the Medicare decision begins to resemble the green-card and citizenship decisions discussed earlier in this series.

The real calculation is not only:

How can I spend the least money today?

It is:

How much am I willing to pay today to preserve the ability to change my retirement plan later?

For some people, paying more than $2,000 a year for Part B will not be worthwhile.

For others, it may be the price of keeping a door open ten years from now.

Both conclusions can be reasonable.

What is much less reasonable is canceling everything simply because “Medicare does not work in China,” without understanding the consequences for reenrollment, late penalties, Part D, and Medigap.

Healthcare should not be planned only after illness begins

The first five articles in this series focused mainly on identity and income.

Can the green card be maintained?

Can Social Security continue?

What happens to spousal and survivor benefits?

Why might Social Security be reduced by 25.5% after giving up a green card?

Should someone become a U.S. citizen first?

With Medicare, the problem becomes even more immediate.

Immigration decisions sometimes allow time for reconsideration.

Tax questions can often be recalculated with professional help.

Healthcare does not always give people that much time.

The moment someone truly needs Medicare may also be the moment when that person is least physically and mentally able to handle complicated enrollment rules.

So anyone preparing for long-term retirement in China should ideally understand several things before leaving the United States:

Whether Part A has already been established and whether it is premium-free;

how much Part B currently costs;

what reenrollment rule would apply personally if Part B were dropped;

whether a late enrollment penalty could apply;

what to do with Part D;

whether Medicare Advantage coverage will change after moving outside the plan’s service area;

what could happen to Medigap if it is canceled;

and, perhaps most importantly:

If I suddenly decide to return to the United States ten years from now, on what date do I want my medical coverage to be usable?

There is no single answer that works for everyone.

But there is one useful principle:

Do not decide health coverage only according to where you live today. Plan according to where you may need healthcare later in life.

That may be the most practical calculation in this entire cross-border retirement series.

Because green cards, citizenship, and Social Security ultimately answer questions about whether something is possible.

Healthcare asks something more urgent:

When you finally need it, will there still be time?

About This Series | Before Retiring in China, There Are Some Numbers to Work Out

For many first-generation immigrants from China who have lived in the United States for years, returning to China for long-term retirement can seem like a natural choice. But putting that plan into practice raises interconnected questions: whether a green card can be maintained, whether Social Security can continue to be paid abroad, how spousal and survivor benefits work, how tax status may change, whether becoming a U.S. citizen before retirement makes sense, and how Medicare should be handled after moving to China long term.

This series does not attempt to decide whether it is “better” to retire in China or the United States. Instead, it takes a practical approach to issues that are often confused with one another. Cross-border retirement requires planning not only where to live, but also how immigration status, retirement income, taxes, and healthcare will continue to work together over the long term.
