Moving out of your Medicare Advantage (MA) plan's service area in 2026 is a qualifying life event that Medicare treats differently from the ACA Marketplace. Medicare Advantage plans are county-based, so a plan that covers your doctors in Phoenix may not exist in Denver, and Medicare requires your plan to end your enrollment when you permanently leave its service area. The good news is that Medicare gives you a Special Enrollment Period (SEP) to pick replacement coverage without penalty. According to medicare.gov, the SEP begins the month before you move if you tell your plan in advance, and continues for 2 full months after you move. If you report the move late, the window starts the month you tell the plan and still runs 2 full months after the month of the move. During that window you can switch to a new MA plan with or without drug coverage, join a standalone Part D plan, or return to Original Medicare. Marketplace plans and Form 1095-A subsidies are not part of this decision, because people with Medicare generally cannot buy Marketplace coverage for the same benefits. The sections below give the exact 2026 dates, the seven steps to enroll, and the Medigap rights most people overlook.
Original Medicare Part B costs $202.90 per month in 2026, with a $283 Part B deductible and a $1,736 Part A inpatient deductible, and Original Medicare has no out-of-pocket maximum. Medicare Advantage plans cap in-network spending at a federal ceiling of $9,250 in 2026 and often bundle drug, dental, and vision benefits, but only inside a network. Which path fits depends on whether your current doctors are near your new home, which drugs you take, and how much financial risk you can carry. KFF's 2026 Medicare Advantage analysis at kff.org reports that a majority of Medicare beneficiaries choose Advantage plans, so most movers look for a new plan first. Medigap is the alternative: you keep any doctor who accepts Medicare, and the 2026 guaranteed-issue window means no medical underwriting if you apply on time. Employer retiree coverage and COBRA can also interact with Medicare after a move, so check with your former employer before you cancel anything. Act early: coverage from a new plan starts the first day of the month after the plan receives your request, so gaps are avoidable only if you enroll before your old plan ends.
7 Steps to Get Coverage
Common Mistakes That Cost People Thousands
Most costly errors after a service-area move come from waiting for the plan to act instead of choosing coverage yourself.
- Waiting for your old plan to disenroll you. Original Medicare then starts with no drug coverage, and a Part D gap of 63 days or more can add a lifelong late-enrollment penalty.
- Telling the plan about the move after you relocate. Advance notice starts the SEP the month before you move; late notice shortens your window.
- Choosing a plan before checking whether your new doctors and pharmacies are in network for the new ZIP code.
- Missing the Medigap window. After 63 days past your MA end date you may face medical underwriting and can be denied in most states.
- Cancelling employer retiree coverage or COBRA without confirming how it coordinates with Medicare in your new state.
How the 2026 Medicare SEP for a Service-Area Move Works
Medicare Advantage service areas are drawn by county, and each plan sets its own list. When you permanently move outside that list, federal rules require the plan to disenroll you, and Medicare opens a Special Enrollment Period so you are not stuck. The SEP begins the month before you move if you notify your plan in advance, and continues for 2 full months after you move, per medicare.gov and the CMS guide Understanding Medicare Advantage and Medicare Drug Plan Enrollment Periods at cms.gov. If you notify the plan late, the window starts the month you report the move. During the SEP you can join a new MA plan, join a standalone Part D plan, or drop to Original Medicare. Temporary absences work differently: plans generally disenroll members after 6 continuous months away, and some plans with visitor or traveler benefits allow up to 12 months. A move within your plan's service area does not trigger the SEP. Moves into or out of an institution, such as a nursing home, have their own SEP rules. In 2026, a July 1 move, for example, produces a SEP from June 1 through September 30, 2026, and any plan chosen in September starts October 1.
Medigap Guaranteed Issue After Leaving an MA Plan in 2026
Medigap guaranteed-issue rights are the most valuable and least known protection for people who move out of a Medicare Advantage service area. Federal Medicare rules give you a guaranteed right to buy certain Medigap policies if you move out of your MA plan's service area, so insurers cannot deny you or charge more because of health conditions. You may apply as early as 60 days before your MA coverage ends and no later than 63 days after it ends, and Medigap coverage cannot start until your MA coverage has ended. Keep every termination letter, notice, or email showing the MA end date, since insurers may request copies. The plans covered by this right are A, B, D, G, K, and L, while C and F are limited to people first eligible for Medicare before January 1, 2020. Medigap premiums vary widely: Plan G commonly runs about $100 to $300 per month in 2026 depending on age and state. Pair Medigap with a standalone Part D plan, because Medigap sold today does not include drug coverage. Outside the window, insurers in most states may require medical underwriting and can decline you for conditions such as heart disease or diabetes.
Medicaid and Medicare Savings Programs After Your 2026 Move
Medicaid and Medicare Savings Programs (MSPs) do not follow you across state lines, so a move to a new state means applying again with your new state's agency, and medicaid.gov lists each state's portal. State programs go by different names: California's Medi-Cal, Massachusetts's MassHealth, Arizona's AHCCCS, Tennessee's TennCare, and Wisconsin's BadgerCare. A Qualified Medicare Beneficiary (QMB) program can pay your Part B premium of $202.90 per month in 2026 plus deductibles and coinsurance, with the federal income guide at 100% of the Federal Poverty Level, about $15,960 for a single person in 2026 (states may apply small disregards). People who are dually eligible can also join a Dual-Eligible Special Needs Plan (D-SNP), and dual or Extra Help enrollees have extra options to change drug plans outside the usual windows. Medicaid enrollment is year-round, so there is no deadline, but applying quickly avoids gaps because your old state's benefits end when you establish residency elsewhere. Marketplace coverage through healthcare.gov is generally not available to people who already have Medicare Part A, so an MSP or Medicaid is the affordable route, not a Marketplace subsidy.
Frequently Asked Questions
What is the SEP window when I move out of my Medicare Advantage plan's service area?
The SEP starts the month before you move, if you tell your plan your new address in advance, and ends on the last day of the 2nd full month after you move, according to medicare.gov. For a June 15, 2026 move, that is May 1 through August 31, 2026, about 4 months. If you notify the plan only after moving, the window begins the month you report the move and still runs 2 full months after the month of the move. During the SEP you can join a new Medicare Advantage plan, join a standalone Part D plan, or return to Original Medicare. Your new coverage starts the first day of the month after your chosen plan receives your request, so enrolling early in the window prevents a gap.
How do I document my move for the Medicare SEP?
Medicare usually needs only your new address, since the plan verifies the ZIP code against its service area. Have a lease, utility bill, deed, or driver's license ready in case the plan asks for proof, and keep the date you told your plan about the move. For a Medigap application under guaranteed-issue rights, send the plan termination letter or any notice showing your MA end date. Update your address with Social Security at ssa.gov or 1-800-772-1213 so Medicare notices reach you. Save call confirmation numbers, since they show you acted within the 2026 SEP.
What if I miss the SEP window after moving out of my MA plan area?
Your old plan disenrolls you and you fall back to Original Medicare, which in 2026 means a $202.90 Part B premium, a $283 deductible, and no prescription coverage. You then wait until the Annual Election Period, October 15 to December 7, 2026, for coverage starting January 1, 2027. A Part D gap of 63 days or more can add a late-enrollment penalty of 1% of the national base premium per uncovered month for life. Medigap medical underwriting may also apply after the guaranteed-issue window closes, so acting inside the SEP protects both your drug coverage and your Medigap options.
Can I get retroactive coverage after moving out of my MA plan's service area?
Medicare SEP enrollments are not retroactive. A new Medicare Advantage or Part D plan starts the first day of the month after the plan receives your request, so you must enroll before your old plan's end date to avoid a gap. Your old plan generally ends coverage on the last day of the month it disenrolls you. Medigap also cannot start until your MA coverage has ended, but you can apply up to 60 days early so that Medigap starts the day after MA coverage stops. Medicaid can sometimes cover up to 3 prior months of bills in states that allow it.
What state-specific rules apply after moving out of my MA plan's service area?
The Medicare SEP is federal, but Medigap and Medicaid rules vary by state. New York and Connecticut give year-round Medigap guaranteed issue, and California offers a 60-day birthday rule after your birthday each year. Medicaid and Medicare Savings Programs do not transfer across state lines, so you reapply with your new state, such as Medi-Cal in California, MassHealth in Massachusetts, AHCCCS in Arizona, or TennCare in Tennessee. Check your new state's insurance department for Medigap rules and use the Medicare Plan Finder at medicare.gov for plan availability by ZIP code in 2026.
Can I keep my current Medicare Advantage plan if I only move temporarily?
Most plans keep you enrolled for up to 6 continuous months of temporary absence from the service area, and some plans with visitor or traveler benefits allow up to 12 months. Use of out-of-area care is limited to emergencies and urgent care unless the plan offers a visitor program, so routine care may not be covered. If the move becomes permanent, contact your plan right away because your SEP timing depends on the date you report the move. Call the member services number on your card to confirm how your plan classifies your absence in 2026.
Should I choose Original Medicare with Medigap or a new Medicare Advantage plan after moving?
Choose Original Medicare with Medigap if you want any-doctor access nationwide and predictable costs, and choose a new Medicare Advantage plan if you want lower premiums and bundled extras inside a local network. In 2026 a Medigap Plan G costs about $100 to $300 per month on top of the $202.90 Part B premium, while many MA plans have $0 premiums and an in-network maximum out-of-pocket of up to $9,250. Your Medigap guaranteed-issue right lasts from 60 days before to 63 days after your MA coverage ends, so decide within that time. Compare both at medicare.gov before you commit.
Do I qualify for Medicaid or a Medicare Savings Program after my move?
Qualification depends on your income, assets, and new state. A Qualified Medicare Beneficiary program can pay your $202.90 Part B premium in 2026 if your income is around 100% of the Federal Poverty Level, about $15,960 for one person in 2026, and other MSP tiers reach somewhat higher income levels. Medicaid never transfers between states, so apply with your new state agency listed at medicaid.gov, for example Medi-Cal in California or MassHealth in Massachusetts. Medicaid enrollment is year-round, and being dually eligible lets you join a Dual-Eligible Special Needs Plan. Our screener checks eligibility in about 2 minutes.
