Medicare works in all 50 states, but which doctors and hospitals accept it varies by location and plan type
Your Medicare coverage is national — you can use it in any state. However, the specific doctors, hospitals, and clinics that accept Medicare differ from place to place. If you have Original Medicare (Part A and Part B), you can see any provider in the country who accepts Medicare patients. If you have a Medicare Advantage plan (Part C), your network of in-network providers may be limited to a specific region, and using out-of-network care usually costs you more.
The key difference is whether you have a plan with geographic boundaries. Original Medicare has no state lines — a hospital in Florida accepts the same Medicare card as one in Washington. But a Medicare Advantage plan sold by an insurance company often restricts you to doctors and hospitals in a defined service area, which might be a county or a multi-county region.
Key Takeaways
- Original Medicare (Part A and Part B) is accepted by any participating provider nationwide, with no state restrictions.
- Medicare Advantage plans have network boundaries that usually follow county or regional lines, not state lines, and using out-of-network providers costs more.
- If you move to another state, you can keep Original Medicare without any change, but you may need to switch Medicare Advantage plans if your new state is outside your plan's service area.
- Emergency care is covered nationwide under both Original Medicare and Medicare Advantage, even if the hospital is out of network.
- You can check whether a specific doctor or hospital accepts your Medicare plan by calling them directly or using the Medicare provider search tool on Medicare.gov.
How Original Medicare works across state lines
Original Medicare is administered by the federal government and works the same way in every state. When you show your Medicare card to a doctor or hospital that accepts Medicare, they bill Medicare directly. There are no state-specific rules, no separate enrollment by state, and no network boundaries. You can see a cardiologist in New York one month and a different cardiologist in Arizona the next month, and both will accept your coverage the same way.
The only variation is which individual providers choose to accept Medicare patients. Some doctors and hospitals do not participate in Medicare, or they participate but limit the number of Medicare patients they see. This is a provider choice, not a state rule. If you need to find a participating provider in a new state, you can search Medicare.gov's provider directory or call the office directly and ask whether they accept Medicare.
Medicare Advantage plans and state boundaries
Medicare Advantage plans are sold by private insurance companies and usually have service areas — the region where the plan operates. These areas are often smaller than a whole state. A Medicare Advantage plan might cover a single county, a few counties, or a multi-county region. If you move outside that service area, you typically cannot keep the same plan.
If you have a Medicare Advantage plan and you move to another state (or to a different part of your current state) that is outside your plan's service area, you have the right to switch to a different Medicare Advantage plan or to Original Medicare. This change is allowed without waiting for the annual enrollment period. Contact your plan directly or call Medicare at 1-800-MEDICARE to discuss your options when you move.
What happens if you travel out of state temporarily
If you are traveling and need medical care, both Original Medicare and Medicare Advantage cover emergency and urgent care anywhere in the United States. An emergency room visit in another state will be covered. For urgent care that is not an emergency, Original Medicare covers you at any participating provider. Medicare Advantage plans may charge you more for out-of-network urgent care, depending on your plan's rules.
If you are traveling and need ongoing care for a chronic condition, call your doctor's office before you leave to ask about coverage in the state you are visiting. Original Medicare patients can see any Medicare-participating provider. Medicare Advantage patients should ask whether the provider they want to see is in their network, or whether their plan covers out-of-network care during travel.
Moving to a new state permanently
If you move to a different state, you do not need to re-enroll in Original Medicare — your coverage continues automatically. You keep the same Medicare card and the same coverage rules. You may want to find new doctors and hospitals in your new state, but that is a matter of personal choice, not a Medicare requirement.
If you have a Medicare Advantage plan, check whether your plan operates in your new state. Some large national plans do, but many regional plans do not. If your plan does not serve your new address, you can switch to a different plan or to Original Medicare. You have 60 days from the date you move to make this change. Contact your current plan or Medicare to confirm whether you need to switch.
Prescription drug coverage across state lines
Medicare Part D (prescription drug coverage) is also national, but the specific drugs covered and the pharmacies in your network vary by plan and by state. If you move to a new state, your Part D plan may still operate there, but the formulary (the list of covered drugs) and your pharmacy network may be different. Call your plan to confirm your coverage in your new state, or check the plan's website.
If your Part D plan does not operate in your new state, you have 60 days to switch to a different Part D plan that does. You can also switch to Original Medicare with a different Part D plan. Medicare.gov has a plan finder tool that shows you which Part D plans are available in your new state.
Checking coverage before you see a provider in another state
Before you schedule an appointment with a doctor or hospital in another state, confirm that they accept your Medicare plan. For Original Medicare, call the provider and ask if they accept Medicare. For Medicare Advantage, ask whether the provider is in your plan's network. You can also search Medicare.gov's provider directory, which lists participating providers by state and specialty.
If you are moving to a new state and want to keep seeing the same doctors, ask your current providers whether they have offices or affiliated providers in your new state. Some large medical systems operate across multiple states and can transfer your records and continue your care.
Frequently Asked Questions
Can I use my Medicare card in every state?
Yes, if you have Original Medicare. Your card works at any provider who accepts Medicare, in any state. If you have Medicare Advantage, your coverage is limited to your plan's service area, which may not cover all states or all parts of a state.
What do I do if I move and my Medicare Advantage plan does not serve my new state?
You can switch to a different Medicare Advantage plan that operates in your new state, or switch to Original Medicare. You have 60 days from your move to make this change without waiting for the annual enrollment period. Contact your current plan or call 1-800-MEDICARE for help.
Does emergency care count as out-of-network if I am traveling?
No. Emergency care is covered nationwide under both Original Medicare and Medicare Advantage, even if the hospital is out of network. You pay the same cost-sharing as you would in-network. Call your plan after the emergency to report the visit.
If I have Original Medicare, do I need to do anything when I move to a new state?
No. Your Original Medicare coverage continues automatically in your new state. You do not need to re-enroll or notify Medicare. You may want to find new doctors and hospitals, but that is optional.
Can I see a doctor in one state and a specialist in another state with the same Medicare coverage?
Yes, if you have Original Medicare. Any Medicare-participating provider in any state will accept your coverage. If you have Medicare Advantage, both providers must be in your plan's network, or you will pay out-of-network costs.
