Should You Drop Medicare Part B When Moving Abroad?

Part B covers doctor visits and outpatient care in the US. It costs $202.90/month in 2026 — and covers almost nothing outside the country. Whether to keep paying for it is one of the most consequential decisions you'll make before you go, because getting it wrong in either direction has permanent financial consequences.

On a different question?

Wondering how long you can stay abroad without losing Medicare? If you split time between the US and abroad, see Medicare for snowbirds. If you're a full-time roamer, see Medicare for perpetual travelers. For the broader "do you lose Medicare when you move abroad" question, the Medicare hub answers it directly.

Want to see the exact numbers for your situation?

The Part B keep-or-drop calculator shows your exact savings, permanent penalty, post-return monthly premium, and break-even age based on how long you plan to be abroad and whether you expect to return.

Keep It or Drop It — It Depends on Your Situation

There's no universal right answer. The decision hinges on one question: how likely are you to return to the US and need medical care there? Find your situation below.

Drop Part B

Fully relocating — no plans to return

You're done with the US. Selling up and moving permanently.

Paying $202.90/month for coverage that won't work abroad is money you don't need to spend. If you stay away for 5 years and return, you'd have paid $12,174 for nothing — plus the permanent penalty on top.

Document your time abroad carefully — you'll need proof to avoid the penalty if you ever return.

Keep Part B

Splitting time — 6+ months abroad, some US visits

You'll be back regularly — family, doctors, seasonal.

At $202.90/month, Part B costs about $2,435/year. A single specialist visit in the US without it could cost $300–500 out of pocket. The math favors keeping it, and the penalty risk makes dropping it a bad bet.

The penalty risk alone makes dropping it not worth it.

Keep Part B

Trial run — 1 to 2 years, likely returning

You're testing the lifestyle before committing.

Dropping Part B for 2 years saves $4,870 — but locks in a permanent 20% premium increase if you return. That break-even takes years to recover and isn't worth it on a trial.

Don't risk a permanent penalty for a trial period.

Check first

Already on Medicare Advantage, moving now

You've been on a Part C plan for years and are relocating abroad.

The Part B decision is secondary to a more urgent issue: Advantage plans can auto-disenroll you after 6 months abroad, and switching back to Original Medicare on the plan's timeline (rather than yours) complicates your options.

Read the Medicare Advantage guide first — then come back to the Part B question.

The Part B Penalty — It's Permanent

Drop Part B and later return to the US? You'll pay more for Medicare every single month — forever. The penalty is 10% of your premium for every 12-month period you went without it. Think of it as a permanent surcharge: one decision you made years ago, quietly adding to your bill for the rest of your life. Figures below use the 2026 standard premium of $202.90/month — higher earners pay more.

Late enrollment penalty

Dropped for 1 year +$20/month forever ($243/year)

Dropped for 3 years +$61/month forever ($730/year)

Dropped for 5 years +$101/month forever ($1,218/year)

Dropped for 10 years +$203/month forever ($2,435/year)

The break-even: how long before the penalty costs more than you saved?

The penalty is permanent — but so are the savings while you're abroad. Here's how they compare if you drop Part B, live abroad, and eventually return. All figures use the 2026 standard premium of $202.90/month.

The break-even works out to roughly 10 years after you return — regardless of how long you were abroad. That's not a coincidence: the penalty scales proportionally with the savings, so the ratio stays constant. What changes is the dollar amounts, not the math.

Abroad for 3 years, then return

Premiums saved while abroad $7,304

Permanent penalty on return +$61/month ($730/year)

If you return at 68 and live to 78, the penalty costs you roughly what you saved. Live longer and it costs you more.

Abroad for 5 years, then return

Premiums saved while abroad $12,174

Permanent penalty on return +$101/month ($1,218/year)

If you return at 70 and live to 80, the penalty costs you roughly what you saved. Live longer and it costs you more.

Abroad for 10 years, then return

Premiums saved while abroad $24,348

Permanent penalty on return +$203/month ($2,435/year)

If you return at 75 and live to 85, the penalty roughly zeroes out your savings. The longer you stay abroad, the later in life you return — and the less the break-even matters.

What the math actually tells you

The break-even is consistently around 10 years after you return — regardless of how long you were abroad. That's because the penalty scales proportionally with the savings. If you return early in retirement and live a long life, the penalty will cost you more than you saved. If you return late — or never — the savings win.

This is why the decision is really about one question: how confident are you that you're not coming back?

One more thing: the penalty applies to the standard base premium only ($202.90), not to any income-adjusted surcharge (IRMAA) you may owe on top. Higher earners paying $300+/month total will find their break-even extends further, because the penalty is smaller relative to the total bill.

There is one exception

If you were living abroad when you turned 65 and weren't yet receiving Social Security, you qualify for a penalty-free enrollment window when you return to the US and establish residency — but it's only 3 months, and you'll need documentation proving you lived outside the US during that time. Don't count on this; plan as if the penalty applies.

If You Decide to Drop Part B: How It Works

Dropping Part B isn't automatic — you have to actively disenroll. Here's what the process looks like and what to have ready.

Step 1

Contact Social Security to request disenrollment

Call 1-800-772-1213 or visit your local Social Security office. You can't drop Part B online. Disenrollment typically takes effect the month after you request it, or the first of a future month you specify.

Step 2

Keep documentation of your time abroad

If you return to the US and re-enroll, Social Security may ask for proof that you were living outside the country during the gap — passport stamps, lease agreements, foreign tax records, or utility bills in your name abroad all help establish this.

Step 3

Note your re-enrollment window if you return

You can re-enroll in Part B during the General Enrollment Period (January 1 – March 31 each year), with coverage starting July 1. The penalty attaches at re-enrollment and continues for life. If you qualify for the special abroad exception, the window is just 3 months from when you re-establish US residency.

Frequently Asked Questions

Does Medicare Part B cover anything outside the US?

Almost nothing. Part B covers doctor visits, outpatient care, and preventive services — but only at US-based providers. There are three narrow exceptions where Medicare covers care abroad: if you're on a ship within 6 hours of a US port, if a foreign hospital is closer to you than a US hospital during a medical emergency in the US (common near some border areas), or if you're traveling through Canada on the most direct route between Alaska and another US state. For the vast majority of expat situations, Part B provides zero coverage outside the country.

How is the Part B late enrollment penalty calculated?

The penalty is 10% of the standard Part B base premium for every 12-month period you went without Part B coverage after first becoming eligible. It's applied permanently — every month, for life. For example, if you went without Part B for 3 years (3 full 12-month periods), your premium increases by 30% permanently. Using the 2026 base premium of $202.90/month, that's an extra $61/month added to your bill forever. One important nuance: the penalty applies to the base premium only, not to any IRMAA income-related surcharge you may owe on top.

I was living abroad when I turned 65 and didn't enroll in Part B. Can I avoid the penalty when I return?

Possibly — but don't count on it. There is an exception for people who were living outside the US when they first became eligible for Medicare and weren't receiving Social Security. If you can document continuous residence abroad during that period, you may qualify for a penalty-free enrollment window when you return and re-establish US residency. The window is only 3 months, and you'll need documentation like passport stamps, lease agreements, foreign tax records, or utility bills. Plan as if the penalty applies and treat this as a potential upside if it turns out you qualify.

Can I drop Part B and pick it back up later if my plans change?

Yes, but re-enrolling comes at a cost. You can re-enroll during the General Enrollment Period (January 1–March 31 each year), with coverage starting July 1 of that year. The permanent penalty attaches at re-enrollment and continues for life, calculated on every 12-month period you went without coverage. If you qualify for the abroad exception, you have a separate 3-month window when you return and re-establish US residency — but you'll need documentation to prove you were living outside the US during the gap.

I pay a higher Part B premium because of my income (IRMAA). Does the penalty apply to my full premium?

No. The late enrollment penalty applies only to the standard base premium ($202.90/month in 2026), not to the IRMAA income-related surcharge you pay on top. So if you pay $350/month total (base plus IRMAA), the penalty is calculated on $202.90 only. That's actually somewhat good news for higher earners: your penalty is smaller relative to your total bill, and your break-even calculation on whether to drop Part B extends further in your favor.

On a Medicare Advantage plan? That changes the order of operations.

The Part B decision is step two if you're on Advantage. Step one is switching to Original Medicare before the 6-month abroad rule triggers auto-disenrollment on your plan's timeline instead of yours.
