Your Medicare Advantage Service Area: What Happens When You Travel or Move

Medicare Advantage plans are built around a geographic footprint called a service area. That boundary shapes who can join, where you get routine care, and what happens when life takes you across the country for a few weeks, a few months, or for good. Here is a plain-English guide to how service areas work and what your options are when you travel or move.

What a "service area" actually means

A Medicare Advantage plan's service area is the geographic area you must live in for the plan to accept you as a member. For plans that limit which doctors and hospitals you use (such as HMOs), the service area is also generally where you get your routine, non-emergency care. Plans can — and in some cases must — disenroll members who move outside it.

That doesn't mean you're stuck at home. Medicare Advantage plans are required to cover emergency care and urgently needed services when you're temporarily outside the service area. Even HMO plans must cover urgent care away from home, and they must cover temporary out-of-area dialysis, whether or not the dialysis facility is in the plan's network. So a weekend trip, a family visit across the country, or a medical surprise on vacation won't leave you without coverage for emergencies or urgent needs.

What's not automatically covered when you're away is routine care — a scheduled physical, a non-urgent specialist visit, elective procedures — unless your plan specifically offers a travel benefit.

Short trips vs. long absences

The rules get more specific when you're gone for a while.

If you haven't moved, but you've been away from the service area for more than 6 consecutive months, your plan must disenroll you — unless the plan offers a visitor/traveler benefit.

A visitor/traveler benefit, when offered, may allow you to stay enrolled during an absence within the United States of more than 6 but less than 12 consecutive months. (A plan may limit this benefit to certain areas.) While you're using it, the plan must furnish all of your Part A and Part B services, along with any supplemental benefits, at the same cost sharing you'd pay back home. On the first day of the 13th month after you left, you're automatically disenrolled.

Not every plan offers a visitor/traveler option, and the specifics differ by plan. If you split your year between two regions or take long trips, it's worth asking your plan — before you go — whether this benefit is available and how it works.

One subtle rule to know: you can be considered "temporarily absent" from the service area if plan mail sent to your address is returned by the Postal Service as undeliverable with no forwarding address. Keeping your mailing address current with your plan matters.

How the plan tells you

If your plan determines you live outside the service area, it must send you a written disenrollment notice within 10 calendar days of confirming that. For a temporary absence that triggers disenrollment, the notice goes out in the first 10 calendar days of the sixth month away. For members using a visitor/traveler benefit, the notice arrives in the first 10 calendar days of the last month of the allowed absence.

The takeaway: watch your mail, and open anything from your plan promptly.

When you move

Moving creates specific rights.

If you move to an address outside your plan's service area, you get a Special Enrollment Period. It begins the month you move — or the month before, if you tell the plan in advance — and continues for 2 full months after the move. During that window, you can pick a new Medicare Advantage plan that serves your new area, or switch to Original Medicare (with or without a stand-alone Part D plan). If you don't choose a new Medicare Advantage plan, you'll be enrolled in Original Medicare when your old plan drops you.

You also get a Special Enrollment Period if you move to a new address that's still inside your current plan's service area but where new plan options are available to you.

People with Medicaid or Extra Help

If you have Medicaid or qualify for Extra Help with Part D costs, you have additional flexibility. Since 2025, there is a monthly Special Enrollment Period that lets you move to Original Medicare paired with a stand-alone Part D plan, or switch from one stand-alone Part D plan to another. If you're a full-benefit dual-eligible (you have both Medicare and full Medicaid), you can join an integrated Dual Eligible Special Needs Plan (D-SNP) in any month.

Weighing your choices

If you travel often or expect to relocate, think about how your coverage fits your life.

Medicare Advantage plans bundle Part A, Part B, and usually Part D, often with extras, but they operate within a service area and typically steer you to a network for routine care. Original Medicare, paired with a stand-alone Part D plan — and often a Medigap policy to help with cost sharing — travels with you anywhere in the U.S. that accepts Medicare, but you pay separate premiums and Medigap rules on when you can buy a policy vary. Neither approach is "better"; they involve different trade-offs around networks, costs, portability, and paperwork.

Dates and dollars worth knowing

A few program-level facts for context:

• The Annual Enrollment Period for 2027 coverage runs October 15 – December 7, 2026; choices take effect January 1, 2027.
• In 2027, the Part D out-of-pocket cap will be $2,400 (it's $2,100 in 2026), and no Part D plan may charge more than a $700 deductible.
• The 2027 Part B standard premium and deductible, along with the IRMAA income brackets, have not yet been announced; CMS typically announces them in the fall.
