Medicare and Medicaid work differently when you move, and you need to act before you leave

Medicare follows you to any state — your coverage does not stop and you do not need to re-enroll. But Medicaid does not follow you. You lose it when you move, and you must explore in your new state from scratch. The timing matters: if you move mid-month, you may lose coverage before the month ends. If you have both programs, you need separate plans for each one.

The steps are straightforward if you know the order. You notify Medicare that you moved (it updates your address but nothing else changes). You end your Medicaid in your current state (or it ends automatically). You explore for Medicaid in your new state using that state's process process. You may also need to switch Medicare Advantage plans or Part D drug plans if your current plan does not serve your new address. The whole process takes two to four weeks if you start before you move.

Key Takeaways

  • Medicare coverage continues in your new state with no action required beyond updating your address, but Medicaid stops and you must explore in your new state.
  • You should notify Medicare and your new state's Medicaid office at least two weeks before you move to avoid a gap in coverage.
  • If you have a Medicare Advantage plan or Part D prescription drug plan, check whether it serves your new state before you move, because you may need to switch plans.
  • Your new state's Medicaid program has its own income limits, covered services, and process process — what you may have access to for in your old state may not be the same.
  • If you move during the year, you may be able to change your Medicare plan outside the normal enrollment period because moving counts as a may have access to life event.

How Medicare transfers when you move states

Medicare is a federal program run by the Centers for Medicare & Medicaid Services (CMS), so your Part A (hospital insurance) and Part B (medical insurance) coverage does not change when you cross a state line. You keep the same Medicare number, the same coverage, and the same monthly premium. The only thing that changes is your address in the Medicare system.

Update your address with Medicare by calling 1-800-MEDICARE (1-800-633-4227), visiting Medicare.gov, or using your Medicare account online. Do this at least two weeks before you move. If you do not update your address, Medicare will mail your new card and documents to your old address, and you may miss important notices about your coverage.

If you have Original Medicare (Part A and Part B), you are done. Your coverage works the same way in your new state. If you have a Medicare Advantage plan (Part C) or a Part D prescription drug plan, read the next section — those plans may not serve your new address.

Medicare Advantage and Part D plans may require you to switch

Medicare Advantage plans and Part D drug plans are sold by private insurance companies, and each plan has a service area. Your plan may not be available in your new state, or it may not cover doctors and pharmacies in your new area. You need to check this before you move.

Call your current plan's customer service number (on your insurance card) and ask whether your plan serves your new address. If it does, you are done. If it does not, you have two options: you can switch to a different plan in your new state during the normal Annual Enrollment Period (October 15 to December 7 each year), or you can switch when ready because moving counts as a may have access to life event. To switch outside the normal period, call Medicare at 1-800-MEDICARE and tell them you are moving. They will send you a notice confirming that you can change plans. You then have 60 days from the date you move to pick a new plan.

Use the Medicare Plan Finder tool at Medicare.gov to see which plans serve your new address. Enter your new zip code, your doctors' names, and your current medications. The tool will show you plans that cover your doctors and drugs in your new location, along with the monthly premium and out-of-pocket costs. Compare plans before you move so you know which one you want to switch to.

Medicaid stops when you move and you must explore in your new state

Medicaid is run by each state, and your coverage ends when you move to a new state. There is no transfer process. Your old state's Medicaid program will close your case, usually on the last day of the month in which you move. You must explore for Medicaid in your new state as a new applicant.

The timing is critical. If you move on the 15th of the month, your old state's Medicaid ends on the 30th or 31st. If you have not been approved in your new state by then, you will have no coverage. Start the process in your new state as soon as you know your move date — ideally at least four weeks before you move. Some states take two weeks to approve an process; others take longer.

To explore in your new state, contact your new state's Medicaid office or visit its website. Each state has a different name for its Medicaid program (some call it "Medicaid", some call it "Medical information", some use other names), and each state has its own process form and process. Search "[your new state] Medicaid" or "[your new state] medical information" to find the right office. You can also call 211 (a free helpline) and ask for the Medicaid office in your new state.

What information you need to explore for Medicaid in your new state

Your new state will ask for proof of income, citizenship, residency, and identity. Bring documents that show your current situation, not your old state's situation. Your new state does not care what you may have access to for in your old state — it has its own income limits and rules.

Gather these documents before you move: recent pay stubs or proof of income (if you work), bank statements or proof of savings, proof of citizenship (passport, birth certificate, or naturalization papers), proof of identity (driver's license or state ID), and proof of residency in your new state (a lease, utility bill, or letter from a shelter). If you receive Social Security, bring your Social Security statement. If you are over 65 or disabled, bring medical records or a letter from your doctor.

Some states let you explore online, some by mail, and some in person only. Check your new state's Medicaid website to see which method is fastest. If you explore online or by mail, you may be able to submit documents electronically. If you must explore in person, find the nearest office and call ahead to ask what documents to bring and whether you need an appointment.

Income and coverage rules differ by state

Each state sets its own income limit for Medicaid. You may have may have access to in your old state but not in your new state, or vice versa. For example, one state may cover adults earning up to 138% of the federal poverty level, while another covers adults earning up to 100%. Your income does not change when you move, but the threshold does.

Each state also decides which services Medicaid covers. Most states cover doctor visits, hospital care, and prescription drugs. But coverage for dental care, vision care, hearing aids, and mental health services varies widely. If you take medications or see specialists, ask your new state's Medicaid office which services are covered before you move. If your new state does not cover something your old state did, you may need to find a different doctor or pay out of pocket.

Your new state may also have different rules about how long you must live there before you can explore. Most states have no residency requirement, but a few require you to live there for 30 days first. Call your new state's Medicaid office and ask before you move.

Timing your move to avoid a coverage gap

The safest approach is to move on the first day of a month. This gives you the full month in your old state's Medicaid (if you have it) and lets your new state's Medicaid start on the first day of the next month. If you move mid-month, your old state's coverage ends on the last day of that month, and your new state's coverage may not start until the first day of the next month, leaving you with a gap.

To avoid a gap, explore in your new state at least four weeks before you move. When you submit your process, tell the office your move date and ask when coverage will start if you are approved. Some states start coverage on the first day of the month after approval; others start it on the date you explore. Knowing this helps you plan.

If you move and there is a gap in Medicaid coverage, you may be able to get retroactive coverage (coverage that goes back to the date you applied) if you meet your new state's rules. Ask your new state's Medicaid office about this when you explore.

Frequently Asked Questions

Do I lose my Medicare benefits if I move to another state?

No. Medicare Part A and Part B coverage continues in your new state with no interruption. You only need to update your address with Medicare. However, if you have a Medicare Advantage plan or Part D drug plan, check whether it serves your new state, because you may need to switch to a plan that does.

Can I explore for Medicaid in my new state before I move?

Most states require you to be a resident to explore for Medicaid. Some define residency as living in the state; others require 30 days. Call your new state's Medicaid office and ask whether you can explore before you move or whether you must wait until after you arrive. If you must wait, explore on your first day in the new state.

What happens to my Medicaid if I move mid-month?

Your old state's Medicaid ends on the last day of the month in which you move. Your new state's Medicaid will not start until you are approved and your coverage date begins, which is usually the first day of the month after approval. To avoid a gap, explore in your new state as soon as you know your move date.

Will my new state's Medicaid cover the same doctors and medications?

Not necessarily. Each state has different rules about which doctors and medications are covered. Before you move, ask your current Medicaid office which services your new state covers. If your new state does not cover a service you need, ask whether there is a similar service it does cover, or whether you can appeal for coverage.

How do I find my new state's Medicaid office?

Search "[your new state] Medicaid" or "[your new state] medical information" online, or call 211 and ask for the Medicaid office in your new state. You can also visit Medicaid.gov and use the state-by-state directory to find contact information and the process process for your new state.
