Any move — whether across the street to a new county, into an assisted living facility, or to another state — can trigger a Special Enrollment Period and require you to change your Medicare coverage. These rules are not well known, and missing your window can leave you without the right coverage.
Don't wait until after you move. Your Special Enrollment Period window opens the month before your move date. Acting early gives you the most options and prevents gaps in coverage.
Medicare Advantage plans are tied to a geographic service area — typically defined by county. When you move outside that area, your plan may no longer be able to cover you, and you are entitled to a Special Enrollment Period (SEP) to make a change.
Not all moves are the same. Here is what you need to know for each situation.
Even a move to a nearby town in a different county can affect your Medicare Advantage plan. Your plan's service area is defined by county — crossing a county line may mean your current plan no longer covers you.
May trigger SEP if you move outside your plan's service areaA move to an assisted living facility or independent living community — even one located nearby — is considered a permanent change of residence. This can qualify you for a Special Enrollment Period to review and change your coverage.
Qualifies as a permanent change of residence — SEP eligibleAdmission to a nursing home or skilled nursing facility triggers specific Medicare rights. You may be able to switch to Original Medicare or a different Medicare Advantage plan, and you have Guaranteed Issue rights for Medigap in some circumstances.
Triggers Guaranteed Issue rights in many statesMoving to a new state almost always means your current Medicare Advantage plan cannot follow you. You will need to enroll in a new plan in your new state. The good news: you have a Special Enrollment Period to make that change without penalty.
Almost always requires a new plan — SEP guaranteedThe SEP rules around moving are specific — and the details matter.
Your Special Enrollment Period begins the month before your move and lasts for two full months after the month you move. For example, if you move in June, your SEP runs from May through August.
You can switch from one Medicare Advantage plan to another, switch from Medicare Advantage back to Original Medicare (Parts A & B), or enroll in a new Medicare Advantage plan in your new service area. You may also be able to add or change a Part D drug plan.
If you move within the same county and your plan's service area does not change, you may not qualify for a move-based SEP. However, you should still notify your plan of your new address. If your doctors or preferred facilities change, review your plan's network carefully.
Guaranteed Issue (GI) rights mean an insurance company must sell you a Medigap (Medicare Supplement) policy without medical underwriting — they cannot deny you coverage or charge you more because of a health condition. Moving to a new state and losing your Medicare Advantage plan can trigger GI rights for Medigap. These rights are time-limited, so act quickly.
If you move out of your current plan's service area, your Part D drug coverage may also be affected. You will have a SEP to enroll in a new standalone Part D plan or a Medicare Advantage plan that includes drug coverage (MAPD). Failing to enroll in creditable drug coverage during your SEP can result in a late enrollment penalty.
Yes. Medicare beneficiaries who move into or out of a nursing home or other institution have a continuous Special Enrollment Period — meaning they can change their Medicare Advantage or Part D plan at any time, once per calendar quarter (January–March, April–June, July–September, October–December).
