If you move to another state, your Original Medicare travels with you and the move doesn't interrupt your coverage. What happens next depends on your plan: a Medicare Advantage or Part D plan tied to where you live can change, because moving outside its service area opens a Special Enrollment Period to switch plans or return to Original Medicare.

Coverage Does it continue after a move? What can change What to do
Original Medicare (Parts A and B) Yes, anywhere in the U.S. Nothing; costs are national Nothing required
Medicare Advantage Only if your new address is inside the plan's service area A move out of the area ends the plan Pick a new plan or return to Original Medicare in the Special Enrollment Period
Part D drug plan Only if your new address is inside the plan's service area A move out of the area ends the plan Join a new drug plan in the same window
Medigap Yes; it is guaranteed renewable Your premium can change by address; a Medicare SELECT policy has its own service area Ask your insurer for your rate at the new address

What Happens to Original Medicare If You Move

Start with the reassuring part. Original Medicare, meaning Part A (hospital) and Part B (medical), is a federal program, and its coverage travels with you anywhere in the United States. A move to another state doesn't interrupt it. You keep the same Original Medicare, and there's no gap while the moving truck is on the road.

Your costs don't jump at the state line either. The standard Part B premium is $202.90 a month in 2026 and the Part B deductible is $283, national figures that a new state doesn't reset. Any extra income-related amount depends on income brackets, not state.

The plan side is where a move actually forces a decision.

What Happens to Medicare Advantage and Part D When You Move

Here's where a move can trip you up. Medicare Advantage (Part C) plans and standalone Part D drug plans are sold by private insurers, and each one covers a set service area. Move to an address outside that service area and you can't stay on the same plan.

That's not a penalty, and it's not something you have to fix on your own timeline. A permanent move outside your plan's service area triggers a Special Enrollment Period, a window that lets you pick a new plan in your new area or return to Original Medicare. So the move creates the problem and hands you the fix in the same breath. The window isn't only for people forced off their plan, either: a permanent move that stays inside your plan's service area still opens it if your new address brings new plan options.

A couple of things to know going in. A plan with the same name can have a different drug list, a different pharmacy network and a different premium in your new area, so treat this as a fresh shopping trip rather than a transfer. Medicare's Plan Finder lets you compare the plans offered at your new address side by side. And if you'd rather simplify, the same window lets you drop Medicare Advantage and go back to Original Medicare, then add a Part D plan and, if you want one, a Medigap policy. Moving out of your plan's service area also gives you a guaranteed issue right to buy certain Medigap policies sold in your state if you switch to Original Medicare, as long as you apply no more than 63 days after your Medicare Advantage coverage ends.

How Long Do You Have to Switch Plans After You Move?

The timing is the part people most often get wrong, so let's be precise. According to Medicare's Special Enrollment Period guidance, your chance to switch begins when you move and continues for 2 full months after you move. If you tell your plan before you move, that window opens earlier: it begins the month before the month you move and continues for 2 full months after.

Say you're moving on June 15. If you tell your plan in May, your window opens May 1 and runs through August 31. If you wait until you've moved, it opens June 15 and still ends August 31. So a heads-up call to your plan buys you extra time to line up new coverage.

1
Step 1

Tell your current Medicare Advantage or Part D plan you're moving, ideally before the move, using the number on your member ID card. That opens the window a month early

2
Step 2

Let Social Security know your new address so your records follow you

3
Step 3

Compare the Medicare Advantage and Part D plans available at your new address on Medicare Plan Finder, checking the drug list and provider network, not just the premium

4
Step 4

Enroll in a new plan or switch to Original Medicare within the Special Enrollment Period so your drug coverage doesn't lapse

5
Step 5

Stuck? Call 1-800-MEDICARE (1-800-633-4227), open 24 hours a day, 7 days a week except some federal holidays. Your state's SHIP (State Health Insurance Assistance Program) gives free, unbiased counseling, and you can find yours at shiphelp.org or at 1-877-839-2675.,

If you've moved out of your Medicare Advantage plan's service area and let the window close without joining a new plan, you'll be enrolled in Original Medicare when the old plan drops you. And if that leaves you 63 days or more without creditable drug coverage, a Part D late-enrollment penalty can be added to your premium for as long as you have Part D. Acting inside the window is what keeps things clean.

Do You Need to Change Your Medigap Policy?

If you have Original Medicare plus a Medigap (Medicare Supplement) policy, moving is usually simpler than with Medicare Advantage. Any Medigap policy issued since 1992 is guaranteed renewable, so the insurance company can't cancel your Medigap policy as long as you stay enrolled and pay the premium. The exception to watch is a Medicare SELECT policy, which has its own service area: if you move out of it, you have a guaranteed issue right to buy a Medigap policy sold in your current state or in the state you're moving to.

The wrinkle is money, not coverage. Call your insurer and ask what your rate will be at the new address, because where you live is one of the factors that sets a Medigap premium. How much it moves depends on how the policy is priced. Community-rated policies charge generally the same premium regardless of age, issue-age policies base it on your age when you bought, and attained-age policies rise as you get older.

Switching to a different policy is harder. Outside your 6-month Medigap Open Enrollment Period, you can usually switch only in specific situations where you have a guaranteed issue right, and if you switch anyway you may pay more and have to answer medical questions. Some states add switching rights, such as California's 60-day window after your birthday each year. So you can usually keep the policy you have, and your state's insurance department or SHIP can tell you what your new state allows.

Frequently Asked Questions

Do I have to re-enroll in Medicare when I move to another state?

Not for Original Medicare. Part A and Part B are federal and their coverage travels with you anywhere in the United States, so a move to another state doesn't interrupt it. What can need changing is a Medicare Advantage or Part D plan, because those are tied to a local service area.

Will my Medicare cost more in another state?

Your Original Medicare costs don't change: the standard Part B premium ($202.90 in 2026) and the Part B deductible ($283 in 2026) are national figures, and the extra amount higher-income enrollees pay is set by income, not state. What can differ by state are the premiums for private Medicare Advantage, Part D, and Medigap plans, which insurers set locally.

What if I miss the Special Enrollment Period?

Medicare's yearly Open Enrollment runs October 15 through December 7, and during it you can join, drop or switch a Medicare Advantage or drug plan, with changes starting January 1. That's your fallback, but you may spend months in Original Medicare, or without drug coverage, until then. If you're enrolled in a Medicare Advantage plan, you also get one change between January 1 and March 31. Don't count on those windows when the Special Enrollment Period is open.

What about Medicaid or Extra Help if I move?

Medicaid is run by each state, so a move to a new state means applying or transferring through the new state's Medicaid agency; see the Medicaid guide under Learn More. A SHIP counselor can also help with Medicaid and Extra Help applications.

How long do I have to switch plans after I move?

Your Special Enrollment Period begins when you move and lasts 2 full months after. If you tell your plan before you move, it begins the month before the move and still runs 2 full months after, giving you a bit more time.

What if I don't change my Medicare Advantage plan after moving?

If your new home is outside the plan's service area, you can't keep that plan. Use the Special Enrollment Period to pick a plan in your new area or return to Original Medicare. If you don't join a new Medicare Advantage plan during the window, you'll be enrolled in Original Medicare when your old plan drops you. If you want drug coverage after that, join a Medicare drug plan in the same window, because going 63 days or more without creditable drug coverage can add a Part D late-enrollment penalty for as long as you have Part D.

Does my Medigap policy still work in a new state?

In most cases you keep it. Any Medigap policy issued since 1992 is guaranteed renewable, so the insurance company can't cancel it as long as you stay enrolled and pay the premium. The exception is a Medicare SELECT policy: moving out of its service area gives you a guaranteed issue right to buy a Medigap policy sold in your current state or the state you're moving to. Medigap premiums also vary by where you live, so ask your insurer what your rate will be at the new address.
