Your Medicare works in all 50 states, but how you use it changes depending on where you are

Yes, your Medicare coverage follows you to any state in the United States. Medicare Part A (hospital insurance) and Part B (medical insurance) are federal programs, so they work the same way everywhere. However, the doctors, hospitals, and clinics that accept Medicare vary by location, and your prescription drug coverage may change if you move permanently. If you are traveling, your coverage stays active. If you are moving, you may need to make changes to your plan.

The key difference is between temporary travel and a permanent move. When you travel to another state for vacation or a short visit, your existing Medicare coverage continues without any action on your part. When you move to a new state to live, you enter a special enrollment period that lets you change your Medicare Advantage plan or prescription drug plan without waiting for the annual open enrollment period.

Key Takeaways

  • Medicare Part A and Part B work in every state, and you do not need to notify Medicare before traveling.
  • If you have a Medicare Advantage plan, you should check whether your current plan has doctors and hospitals in the state you are moving to, because networks are often regional.
  • When you move to a new state permanently, you have two months to change your Medicare Advantage or prescription drug plan without penalty.
  • If you are moving and your current plan does not serve your new state, you must switch plans during your move-related enrollment period or lose coverage.
  • Original Medicare (Part A and Part B) works everywhere, but supplemental insurance policies may not be available in your new state on the same terms.

How Medicare coverage works when you travel

Your Medicare card is valid in every state, and you do not need to do anything before you leave. When you see a doctor, go to an urgent care clinic, or visit a hospital while traveling, show your Medicare card just as you would at home. The provider will bill Medicare directly, and your coverage works the same way — you pay your deductible and coinsurance the same as you would in your home state.

The only thing to plan for is finding providers who accept Medicare in the state you are visiting. Not every doctor or hospital accepts Medicare, though most do. Before you travel, you can search for Medicare-accepting providers in the area you are visiting by using the Find Care Providers tool on Medicare.gov, or by calling the provider directly and asking whether they accept Medicare.

If you take prescription medications, bring enough with you for your entire trip, or ask your pharmacy whether they can transfer your prescription to a pharmacy in the state you are visiting. Your Part D prescription drug coverage works in all states, but the pharmacy network may be different, and some medications may have different cost-sharing amounts depending on the pharmacy's location.

What changes when you move to another state permanently

A permanent move triggers a special enrollment period that lasts for two months from the date you move. During this time, you can change your Medicare Advantage plan, switch to Original Medicare, or change your Part D prescription drug plan without waiting for the annual open enrollment period (which runs October 15 to December 7 each year). You do not pay a penalty for switching during this window.

The reason this matters is that Medicare Advantage plans are built around regional networks of doctors and hospitals. Your current plan may not have any doctors or hospitals in your new state, or it may have very few. If you move and your plan does not serve your new location, you must switch to a plan that does, or you will have no coverage outside of emergencies.

To start the process, contact Medicare at 1-800-MEDICARE or log into your Medicare.gov account and tell them you have moved. They will confirm your new address and explain which plans are available in your new state. You have until the end of your second month in the new state to make a change.

Medicare Advantage plans and moving to a new state

Medicare Advantage plans (also called Part C) are offered by private insurance companies and usually include prescription drug coverage. These plans have networks — lists of doctors, hospitals, and pharmacies that have agreed to work with that plan. Some networks cover multiple states, but many are limited to a single state or a few counties within a state.

Before you move, check whether your current Medicare Advantage plan operates in your new state. You can do this by logging into your plan's website, calling the plan's customer service number (on the back of your card), or using the Plan Finder tool on Medicare.gov. If your plan does not serve your new state, you will need to switch during your move-related enrollment period.

If you are moving and want to keep the same type of plan (for example, staying with the same insurance company), ask whether that company offers a plan in your new state. If they do, switching between their plans is usually simpler than switching to a different company entirely. If your current plan does not serve your new state and the company does not offer an alternative there, you will need to choose a different plan from a different company.

Original Medicare and supplemental insurance when you move

If you have Original Medicare (Part A and Part B) without a Medicare Advantage plan, your coverage works exactly the same in your new state as it did in your old one. You do not need to change anything, and you do not need to notify Medicare of your move, though updating your address with Social Security is a good idea so Medicare has your correct mailing address.

If you have a Medigap policy (supplemental insurance that works with Original Medicare), the situation is more complicated. Medigap policies are regulated by state, and the plans available and their prices vary by state. When you move, your current Medigap policy may not be available in your new state, or it may be available but at a different price. Some states allow you to keep your current policy even after moving, but others do not.

Contact your Medigap insurance company as soon as you know you are moving and ask what happens to your policy. In many cases, you will have a limited time to switch to a different Medigap plan in your new state without having to answer health questions again. This is called a may provide issue period, and the rules vary by state and by the reason for your move.

Part D prescription drug coverage across state lines

Your Part D prescription drug plan works in all 50 states, but the pharmacy network and the cost of your medications may differ depending on where you are. When you travel, you can use any pharmacy that is in your plan's network, even if it is in a different state. If you cannot find your plan's pharmacy in the area you are visiting, you can use an out-of-network pharmacy, but you will pay more out of pocket and may not be able to get the cost reimbursed.

When you move permanently, your Part D plan may change its network or pricing in your new state. Some medications that were on your plan's formulary (the list of covered drugs) in your old state may not be covered in your new state, or they may have different cost-sharing amounts. After you move, log into your plan's website or call customer service to confirm that your medications are still covered and at what cost.

If your current Part D plan does not cover your medications well in your new state, you can switch to a different plan during your move-related enrollment period. Use the Plan Finder tool on Medicare.gov to compare plans in your new state and see which ones cover your medications at the lowest cost.

Steps to take before and after moving to a new state

Start planning at least one month before your move. First, contact your current Medicare Advantage plan or call 1-800-MEDICARE to find out whether your plan serves your new state. If it does not, use the Plan Finder tool on Medicare.gov to see what plans are available in your new location. Compare the plans based on which doctors and hospitals you want to use and which medications you take.

Once you have moved, contact Medicare within two months to report your new address and to make any changes to your coverage. You can do this by calling 1-800-MEDICARE, by visiting Medicare.gov, or by visiting your local Social Security office. If you are switching plans, make sure your new plan is active before your old plan ends, so you do not have a gap in coverage.

Update your address with your doctor's offices, your pharmacy, and any other healthcare providers you see regularly. This ensures that they have your correct mailing address for bills and appointment reminders. If you have a supplemental insurance policy or a separate prescription drug plan, contact those companies as well to update your address and confirm your coverage continues in your new state.

Frequently Asked Questions

Do I need to tell Medicare I am traveling to another state?

No. Your Medicare coverage is active in all states automatically. You do not need to notify Medicare before you travel. Just bring your Medicare card with you and use it at any provider who accepts Medicare.

What if I move to a new state and my Medicare Advantage plan does not serve that state?

You must switch to a plan that does serve your new state. You have two months from your move date to make this change without penalty. Contact Medicare or use the Plan Finder tool on Medicare.gov to see which plans are available in your new location. If you do not switch and your plan stops covering you, you will have no coverage except for emergency services.

Can I keep my Medigap policy if I move to a different state?

It depends on your state and your insurance company. Some states allow you to keep your policy, while others require you to switch. Contact your Medigap insurance company when ready after you move and ask what options you have. You may have a may provide issue period that lets you switch to a different plan without health questions.

Will my prescription medications cost the same in my new state?

Possibly not. Pharmacy networks and drug prices vary by state and by plan. After you move, check with your Part D plan to confirm your medications are still covered and at what cost. If your costs go up significantly, you can switch to a different Part D plan during your move-related enrollment period.

What should I do if I cannot find a Medicare provider in the state I am visiting?

Call ahead to confirm the provider accepts Medicare before you go. If you cannot find a Medicare provider and need care, you can see an out-of-network provider, but you may pay more out of pocket. Keep your receipts and contact Medicare afterward to ask about reimbursement options.
