Moving to another state after you turn 65 doesn't change Part A or Part B, which work nationwide. A Medicare Advantage or Part D plan may not serve your new address, so the move gives you a Special Enrollment Period to switch that lasts 2 full months after you move. A Medigap policy can generally move with you as long as you keep Original Medicare. The steps you take, and their order, depend on how you get your Medicare today.

Does Medicare work in every state?

Original Medicare does. Part A and Part B are federal programs, and any doctor or hospital in the country that accepts Medicare will take your card. If you have Original Medicare, moving from North Carolina to Tennessee or from New York to South Carolina doesn't change your Part A or Part B coverage at all.

What you do need to update is your address with Social Security, which handles Medicare enrollment. You can do that through your my Social Security account or by calling Social Security. That keeps your Medicare notices, your Medicare card and your premium bills going to the right place.

If you split the year between two homes, such as summers in the mountains and winters in Florida, Original Medicare is often the simpler fit because you aren't tied to one area's network. Most Medicare Advantage plans cover emergency and urgent care anywhere in the country but limit routine care to their network. If you plan to spend months away, ask how the plan treats extended travel before you enroll, and choose the address you consider your permanent residence for plan purposes.

What happens to my Medicare Advantage plan if I move?

Medicare Advantage plans are tied to a service area, usually a set of counties. If you move outside it, you can't stay in the plan. Medicare.gov's Special Enrollment Period rules say you can switch to a new Medicare Advantage plan or a Medicare drug plan, or go back to Original Medicare.

The timing matters:

  • 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, the window begins the month before the month you move.
  • If you don't choose a new plan in time, you'll be enrolled in Original Medicare when the old plan drops you, which can leave you without drug coverage.

The same window applies if you move within your plan's area but have new plan options at the new address.

What happens to my Part D drug plan if I move?

Stand-alone Part D plans also have service areas, often a region of one or more states. If your plan doesn't serve your new state, use the same Special Enrollment Period to join a new drug plan. Don't let drug coverage lapse; going without creditable drug coverage can lead to a Part D late enrollment penalty later. Our page on comparing Part D plans explains what to check first.

Can I keep my Medicare Supplement if I move out of state?

Generally yes. Medicare.gov says you can keep your current Medigap policy no matter where you live, as long as you still have Original Medicare. Your premium may change because insurers often price by location, so ask the company how the new address affects your rate.

Switching to a different Medigap policy after a move is another matter. Outside your 6-month Medigap Open Enrollment Period, you usually don't have a federal right to switch, and an insurer can ask health questions. The main exceptions are a Medicare SELECT policy, which uses a network and gives you a guaranteed right to switch when you move out of its area, and leaving a Medicare Advantage plan because you moved out of its service area. In that second case, federal rules give you a guaranteed issue right to buy certain Medigap plans, and you must apply no more than 63 days after your coverage ends. State rules can add more rights, so check the rules in the state you're moving to. Our Medicare Supplement guide explains the plan letters.

What should I do before and after the move?

Use this checklist so nothing lapses:

  1. Write down your current coverage: Original Medicare or Medicare Advantage, your drug plan and any Medigap policy.
  2. Before you move, check whether your Medicare Advantage or drug plan serves the new county.
  3. Tell your plan your move date. Telling them early opens your switch window a month sooner.
  4. Update your address with Social Security.
  5. Compare plans available at the new address, including whether your doctors and pharmacies are in network.
  6. Enroll in the new plan within 2 full months of the move, and confirm the start date in writing.
  7. If you have Medigap, ask the insurer how your premium will change.
  8. If you have Medicaid or a Medicare Savings Program, reapply in the new state. That help doesn't transfer automatically.

Moving to North Carolina, South Carolina or Tennessee?

Many people relocate to the Charlotte area, to York and Lancaster counties in South Carolina, or to the Nashville area around retirement. Plan choices differ by county, so a plan a friend uses in Mecklenburg County may not be offered in Lancaster County or in Williamson County. If you're moving between Charlotte and Fort Mill or Rock Hill, you are crossing a state line even though the drive is short, and Medicare Advantage and drug plan options change with it. If you have Medicaid help, apply through NC Medicaid, Healthy Connections Medicaid in South Carolina or TennCare in Tennessee after you move.
