Medicare and Medicaid follow you across state lines, but the process and timing differ between them

Medicare is federal, so your coverage moves with you automatically — you do not need to reapply or notify anyone before you move. Your Medicare card, benefits, and premiums stay the same whether you live in Maine or California. What changes is which doctors and hospitals accept Medicare in your new state, and which prescription drug plans and supplemental insurance options are available to you.

Medicaid is state-run, so you will need to apply in your new state. Your old state's Medicaid ends, and you start fresh with your new state's program. The timing matters: if you move mid-month, you may have a gap in coverage, or you may be covered by both states for a short period. The rules about income limits, what services are covered, and what you pay out of pocket can be very different between states.

The practical steps are straightforward, but they happen on different timelines. Medicare requires almost no action from you. Medicaid requires you to contact your new state's program and provide documents proving where you live now.

Key Takeaways

  • Medicare coverage is automatic in your new state; you do not need to reapply, but you should update your address with Social Security to receive mail correctly.
  • Medicaid requires you to apply in your new state within 30 to 60 days of moving, or you may lose coverage; contact your new state's Medicaid office before or immediately after your move.
  • Your new state's Medicaid may cover different services, have different income limits, and charge different copays than your old state, so review the details once you are approved.
  • If you take prescription drugs, you will need to select a new Medicare Part D plan in your new state, because formularies and pharmacy networks change by location.
  • Dual-may be able to access people (covered by both Medicare and Medicaid) should coordinate the move carefully to avoid coverage gaps between states.

How Medicare transfers when you move

Medicare does not require you to do anything to keep your coverage when you move to another state. Your Medicare Part A (hospital insurance) and Part B (medical insurance) follow you automatically because they are administered by the federal government through Social Security. Your may be able to access does not change, your premiums do not change, and you keep the same Medicare number.

What you should do is update your address with Social Security so Medicare can mail you documents, notices about changes to your coverage, and your annual notices of changes for Part D and supplemental plans. You can update your address online at ssa.gov, by phone at 1-800-772-1213, or by visiting a local Social Security office. This takes a few minutes and prevents mail from going to your old address.

The real work comes after the move: finding doctors and hospitals in your new state that accept Medicare, and choosing a new prescription drug plan. Medicare's provider search tool at Medicare.gov lets you search by your new address. You will also need to select a new Part D plan during the open enrollment period (October 15 to December 7 each year) or within 60 days of moving, because drug formularies and pharmacy networks are different in each state.

Medicaid requires you to apply in your new state

Medicaid is run by each state, so your coverage in your old state ends when you move. You must apply for Medicaid in your new state to continue coverage. The application process, income limits, covered services, and copays are all different from state to state, so you cannot assume your new state's Medicaid will work the same way.

Contact your new state's Medicaid office before you move or within the first few days after you arrive. You can find the office through your state's health department website or by calling 211, which is a free referral line that connects you to local health and human services programs. Have your Social Security number, proof of income (recent pay stubs or tax returns), proof of residency (a lease, utility bill, or mail from a government agency), and your birth certificate ready.

Most states require you to apply within 30 to 60 days of moving to avoid a gap in coverage. Some states allow you to apply online, by mail, or in person. Processing usually takes two to four weeks. During this time, you may have a brief period where you are covered by both your old state and your new state — this is normal and does not create a problem. Once your new state approves you, your old state's Medicaid ends automatically.

Understand what changes in your new state's Medicaid

Even if you were approved for Medicaid in your old state, your new state may have different rules. Income limits vary: a person who may have access to in one state might not may have access to in another, or might may have access to for a different category of Medicaid (such as Medicaid for the elderly versus Medicaid for working adults). If your income is close to your state's limit, ask the Medicaid office to run the numbers before you move.

Covered services also differ. Some states cover dental care, vision care, hearing aids, and mental health services more generously than others. If you take medications or see specialists regularly, ask your new state's Medicaid office which drugs and providers are covered before you move. You may need to switch doctors or pharmacies, or your medications may require prior approval from the state.

Copays and deductibles can be higher or lower in your new state. Some states charge no copay for primary care visits; others charge a few dollars. Prescription copays range from free to several dollars per medication depending on the state. Ask for a summary of your new state's cost-sharing rules so you can budget for it.

Coordinate the move if you have both Medicare and Medicaid

If you are covered by both Medicare and Medicaid (called "dual may be able to access"), you need to coordinate both moves to avoid gaps. Medicare is automatic, but Medicaid is not. The risk is that your old state's Medicaid ends before your new state's Medicaid begins, leaving you with only Medicare for a few weeks.

The solution is to apply for Medicaid in your new state as soon as you know your move date — ideally before you move. Provide your new address and move-in date on the application. Many states will process your application and have it ready to activate on your move date, so there is no gap. If you move before your new state approves you, call the Medicaid office and ask them to expedite the application.

Once you are approved in your new state, confirm that your old state's Medicaid has ended. You can check this by calling your old state's Medicaid office or logging into your old state's online portal. You should receive a letter from your old state confirming the end date. Keep this letter for your records.

Update your prescriptions and find new providers

If you take prescription medications, you will need to transfer your prescriptions to a pharmacy in your new state. Ask your current pharmacy to send your prescription records to a pharmacy near your new home, or ask your doctor to send new prescriptions to the new pharmacy. This usually takes a few days.

If you are on Medicare Part D, you must choose a new plan for your new state during the open enrollment period or within 60 days of moving. Use the plan finder at Medicare.gov to see which plans cover your medications at pharmacies in your new area. Prices and coverage vary significantly by state, so comparing plans is worth the time.

For Medicaid prescriptions, your new state may have a different list of covered drugs (called a formulary). Ask your new state's Medicaid office or your new doctor whether your current medications are covered. If a medication is not covered, your doctor may need to request an exception, or you may need to switch to a covered alternative. This process can take one to two weeks, so start it as soon as you know your move date.

Notify your doctors and hospitals before you move

Contact your current doctors and ask them to send your medical records to your new doctors. Provide the names, addresses, and phone numbers of the providers you plan to see in your new state. Most offices can send records electronically or by mail within a few days. Having your records in your new state speeds up your first appointments and ensures your new doctors know your medical history.

If you are in the middle of treatment — such as physical therapy, cancer treatment, or mental health counseling — ask your current provider for a referral to a provider in your new state. They may know someone they can recommend, or they can help you find someone who accepts your new insurance. Starting this process before you move gives you time to schedule your first appointment in your new location.

Frequently Asked Questions

What happens to my Medicare if I move before I update my address?

Your Medicare coverage does not stop, but mail from Medicare and Social Security may go to your old address. Update your address as soon as you move to make sure you receive notices about changes to your coverage, your annual notices of changes for Part D, and other important documents. You can update online at ssa.gov or by calling Social Security.

Can I have Medicaid from two states at the same time?

Yes, briefly. When you move and apply for Medicaid in your new state, there may be a short overlap where you are covered by both your old state and your new state. This is normal and does not cause problems. Once your new state approves you, your old state's Medicaid ends automatically within a few days or weeks.

What if my new state's Medicaid has a lower income limit than my old state?

You may lose Medicaid coverage if your income exceeds your new state's limit. Before you move, contact your new state's Medicaid office and ask whether you will still may have access to. If you will not may have access to, explore whether you can get coverage through your employer, a spouse's plan, or a Medicare supplemental plan instead.

Do I need to reapply for Medicare Part D when I move?

You do not need to reapply for Medicare itself, but you should choose a new Part D plan because drug prices and pharmacy networks are different in each state. You can switch plans during the open enrollment period (October 15 to December 7) or within 60 days of moving. Use the plan finder at Medicare.gov to compare plans in your new area.

What if I move in the middle of the month?

Contact your new state's Medicaid office and provide your move-in date. Many states can process your application so it becomes effective on your move date, avoiding any gap. If you move before your new state approves you, call and ask them to expedite the application. For Medicare, there is no gap — coverage is automatic — but update your address with Social Security right away.
