A move across state lines shakes up a lot of things. Your Medicare coverage is one of them. What happens depends on what kind of Medicare coverage you have. Some of it follows you automatically. Some of it does not. Here is what to expect and what to do before, during, and after the move.
Original Medicare: It Moves With You
Original Medicare, meaning Part A and Part B, is federal. It works the same in every state. Your coverage does not change when you move. Your doctors change, but the program does not.
You do need to update your address with Social Security. That keeps your records straight and makes sure your Medicare Summary Notices and other mail reach you. You can update your address online through your Social Security account, by phone, or in person.
Medicare Advantage: Service Areas Are the Issue
Medicare Advantage plans have service areas. A service area is the geographic region where the plan operates. When you move out of your plan's service area, you generally cannot keep the plan.
This is the biggest moving-related Medicare issue. People assume their plan follows them. It does not.
Here is what typically happens:
If you move within the same service area, nothing changes. Same plan, same network.
Part D: Same Service Area Problem
Standalone Part D drug plans also have service areas. Moving out of the area triggers the same kind of special enrollment period. You can switch to a Part D plan that serves your new address.
If you move but stay in the same service area, your Part D plan continues. Still worth a yearly check during Annual Enrollment, but the move itself changes nothing.
Medigap: The Portable One
Medigap is the most move-friendly coverage you can have. Medigap policies are portable. You keep your policy when you move to another state. The company cannot cancel it because you moved.
Your premium may change. Medigap premiums are often based on your zip code, your age, and local pricing. Moving from a low-cost area to a high-cost area can raise your premium. Moving the other direction can lower it. Ask your company what your new premium will be.
The Special Enrollment Period for Moves
Moving out of your plan's service area gives you a special enrollment period. This is your window to make changes outside the normal enrollment periods. You can:
Enroll in a new Medicare Advantage plan in your new area.
Return to Original Medicare and add a Part D plan.
Switch from one Part D plan to another.
Your Moving Checklist
Two months before the move: look up plans in your new zip code on medicare.gov. Compare Medicare Advantage options and Part D plans. Check networks and formularies.
One month before: notify your current Medicare Advantage or Part D plan of your upcoming move and your new address. Ask about your coverage end date.
Before moving day: enroll in your new plan if you are switching. Confirm the start date. Make sure there is no gap.
Snowbirds and Part-Time Moves
If you split time between two states but keep one as your primary residence, you generally do not trigger a move-based special enrollment period. Your plan is tied to your permanent address.
But your coverage away from home needs attention. Original Medicare works everywhere. Medicare Advantage HMO plans generally cover only emergency and urgent care outside the service area. PPO plans cover out-of-network care at higher cost sharing. If you spend months away, make sure your plan type fits that lifestyle.
