Moving on Medicare: keep your coverage on track.
A new address can quietly change your Medicare coverage — especially if you’re on a Medicare Advantage or Part D plan, which are tied to where you live. The good news: a move usually opens a special window to update your coverage. Here’s what changes, what stays the same, and exactly what to do so nothing slips through the cracks.
What a move does to your coverage
It comes down to one idea: some parts of Medicare travel with you anywhere, and some are tied to your ZIP code. Knowing which is which tells you whether you need to act.
Follows you anywhere
Original Medicare (Parts A & B) works nationwide. Move across town or across the country — your coverage doesn’t change.
Just update your addressPortable, with a catch
A Medigap supplement keeps working nationwide too — but your premium can change with your new location, and switching plans later may involve health questions.
Review your premiumTied to your area
Medicare Advantage and Part D plans have local service areas. Move out of yours and you’ll need to pick a new plan — which is exactly what the moving window is for.
Use your special windowWhat happens to each type of coverage
A quick reference for exactly what to expect — and what to do — for each part of your coverage when you move.
| Coverage | Travels with you? | What to do when you move |
|---|---|---|
| Original Medicare Parts A & B | Yes | Nothing changes with your coverage. Just update your address with Social Security. |
| Medigap Supplement | Yes | Your plan keeps working nationwide, but your premium may change. Switching to a new plan later may require health underwriting unless you have guaranteed-issue rights. |
| Medicare Advantage Part C | Area-based | If you move out of the plan’s service area, you must choose a new plan during your moving window — or you’ll be returned to Original Medicare. |
| Part D Drug plan | ZIP-based | Drug plans are tied to your ZIP code. Use your moving window to join a plan available in your new area. |
Your moving window — and why timing matters
When you move out of your Medicare Advantage or Part D plan’s service area, you get a Special Enrollment Period — a limited window to switch plans, join a new one, or return to Original Medicare. But when you tell your plan changes how long that window lasts.
Tell your plan before you move
Give your plan advance notice and your window is at its widest — giving you the most time to compare and enroll without any gap.
Window: the month before your move, plus 2 full months afterTell your plan after you move
If you notify them only after relocating, the window is shorter — it doesn’t start until you tell them, so you lose that head start.
Window: the month you tell them, plus 2 full months afterDuring this window you can switch to a new Medicare Advantage or Part D plan in your new area, or move back to Original Medicare. If you move out of your plan’s service area and don’t choose a new plan in time, you’ll be dropped from your old plan and automatically enrolled in Original Medicare — which may leave you without drug coverage or the extras you had. The safest move is to line up your new plan before you relocate. See all enrollment periods →
Special situations
A few moves follow slightly different rules. If one of these is you, it’s worth a quick check so nothing catches you off guard.
Moving abroad
Medicare generally doesn’t cover care outside the U.S. If you move overseas, think carefully before dropping Part B — picking it back up later can bring a lasting penalty.
Returning to the U.S.
Move back after living in another country and a special window opens — the month you return, plus 2 full months — to join a Medicare Advantage or Part D plan.
Into or out of a care facility
Moving into or out of a skilled nursing facility or long-term care hospital gives you an ongoing window — for as long as you live there, plus 2 months after you leave.
Your Medicare moving checklist
Five steps to keep your coverage seamless. Do them in order and you won’t miss a beat.
Update your address with Social Security
As soon as you know your move date, update it at SSA.gov or by phone — this keeps your Medicare records and mail current.
Tell your Advantage or Part D plan — before you move if you can
Advance notice gives you the widest possible window to make changes. This is the step most people skip.
Check what’s available in your new area
Advantage and Part D plans are local. Confirm which plans — and which doctors and pharmacies — are available at your new ZIP.
Review your Medigap premium if you have one
Your supplement still works, but your rate may shift with the move. It’s a good moment to make sure you’re still getting the best price.
Enroll during your moving window
Lock in your new coverage before the window closes so there’s no gap — ideally timed to your move date.
