Yes — switching Medicare Advantage plans when you move is allowed outside the normal enrollment windows, because a permanent address change triggers a Special Enrollment Period (SEP). That window lets you pick a new Medicare Advantage plan in your new area, join a standalone Part D drug plan, or drop back to Original Medicare. How long the window stays open depends on one thing most people get wrong: whether you tell your current plan before or after you move.1Medicare. Special Enrollment Periods
Which Moves Qualify
Medicare Advantage plans are tied to specific service areas, so not every move opens the same door. These address changes qualify:
- A move outside your current plan’s service area. This is the most common trigger.
- A move within your plan’s service area, if your new ZIP code or county has Medicare Advantage plans that weren’t available at your old address.
- A return to the United States after living abroad.
- A move into or out of a qualifying institution such as a skilled nursing facility, psychiatric hospital, rehabilitation hospital, or long-term care hospital. Assisted living is not on the institutional list, though a permanent address change from one still counts as a regular move.1Medicare. Special Enrollment Periods
Tell Your Plan Before You Move
The timing rule is simple and worth getting right. Notify your Medicare Advantage plan before your move date and your SEP starts the month before you move and runs for two full months after. Wait until after you’ve relocated and your SEP doesn’t begin until the month you notify them, still running only two months from there.2Medicare.gov. Understanding Medicare Advantage and Medicare Drug Plan Enrollment Periods
Telling the plan early can also mean your new coverage is effective the same day you arrive. Update your address with the Social Security Administration at the same time, since SSA handles Medicare records.3Social Security Administration. Medicare
Finding and Enrolling in a New Plan
Enter your new ZIP code at medicare.gov/plan-compare to see every Medicare Advantage and Part D plan available in that area, with premiums, deductibles, copays, out-of-pocket maximums, drug formularies, and star ratings laid out for side-by-side comparison.4U.S. Centers for Medicare & Medicaid Services. Explore Your Medicare Coverage Options
You can enroll through Medicare’s website, by calling 1-800-MEDICARE, or by contacting the plan directly. A licensed insurance agent can also handle enrollment at no cost. Have your Medicare Beneficiary Identifier and new address ready. Enrolling in a new Medicare Advantage plan automatically disenrolls you from the old one, so there’s no need to cancel separately.5Centers for Medicare & Medicaid Services. Understanding Medicare Advantage Plans
What to Check Before You Pick
Plan availability varies dramatically by region. A county in Florida might have 40 Medicare Advantage options; a rural county in Montana might have two. A few things to confirm:
- Provider network. HMO plans generally restrict you to in-network providers outside of emergencies; PPOs let you go out of network for a higher cost.6Medicare.gov. Understanding Your Medicare Advantage Plans Provider Network
- Drug formulary. Make sure your medications are covered, and note the tier. A low-premium plan with high drug tiers can cost more overall.
- Total costs. Compare monthly premiums, deductibles, specialist copays, and the maximum out-of-pocket limit.
- Extra benefits. Some plans include dental, vision, hearing aids, fitness programs, or over-the-counter allowances.
- Star ratings. A plan rated five stars has its own year-round SEP, which is useful to know if you want to switch again later.
When New Coverage Starts
Under the moving SEP, your new plan’s coverage begins on the first day of the month after the plan receives your enrollment request.1Medicare. Special Enrollment Periods Enroll on March 12 and coverage begins April 1. Your old plan stays active until the new one takes over, so no gap opens up as long as you act inside your SEP window.
Switching to Original Medicare Instead
Some people who move decide Original Medicare with a Medigap supplement makes more sense than another Medicare Advantage plan, especially in areas with sparse networks. Moving out of your Medicare Advantage plan’s service area and switching to Original Medicare gives you guaranteed issue rights for Medigap: an insurer cannot deny you coverage, charge more for health conditions, or impose a pre-existing condition waiting period.7Medicare. Can I Change My Medigap Policy
You have 63 days after your Medicare Advantage coverage ends to apply for Medigap under this protection. Miss that window and insurers in most states can underwrite based on health history, which can mean higher premiums or denial.7Medicare. Can I Change My Medigap Policy
Original Medicare doesn’t include prescription drug coverage, so if you go this route, enroll in a standalone Part D plan during the same moving SEP.
Temporary Moves and Snowbirds
Different rules apply if you’re going to be away from home for an extended stretch rather than permanently relocating. Federal regulations require your Medicare Advantage plan to disenroll you once you’ve been outside the service area for more than six consecutive months, with the disenrollment effective the first day of the following month.8eCFR. 42 CFR 422.74 – Disenrollment by the MA Organization
One exception: plans that offer a visitor or traveler benefit let you stay enrolled for up to 12 consecutive months outside the service area. Check your plan’s Evidence of Coverage to see if yours includes it.8eCFR. 42 CFR 422.74 – Disenrollment by the MA Organization Standalone Part D plans give you more room; disenrollment isn’t required until 12 consecutive months have passed, effective the first day of the 13th month.9CMS. Medicare Advantage and Part D Enrollment and Disenrollment Guidance
What Happens if You Do Nothing
Move out of your plan’s service area without switching and your Medicare Advantage plan will continue to cover emergency and urgent care, but it won’t pay for routine visits, specialist appointments, or other non-emergency services in your new location.5Centers for Medicare & Medicaid Services. Understanding Medicare Advantage Plans Eventually the plan will disenroll you once the move or absence is confirmed, and you’ll be placed back into Original Medicare automatically.1Medicare. Special Enrollment Periods
The Part D Penalty Clock
Inaction gets expensive on the drug side. Go 63 or more consecutive days without creditable prescription drug coverage and you’ll owe a late enrollment penalty when you sign up for Part D. The penalty is 1% of the national base beneficiary premium ($38.99 per month in 2026) multiplied by the number of full months you went without coverage.10Centers for Medicare & Medicaid Services. 2026 Medicare Part D Bid Information and Part D Premium Stabilization Demonstration Parameters That amount gets added to your Part D premium for as long as you have Medicare drug coverage.11Centers for Medicare & Medicaid Services. Creditable Coverage and Late Enrollment Penalty A 10-month gap would add roughly $3.90 per month, permanently. Acting inside your SEP window avoids it entirely.
