Not all doctors accept Medicare, and Medicare does not force them to

Your doctor can choose not to accept Medicare patients. Medicare does not require doctors to take Medicare insurance, and doctors can refuse new Medicare patients, drop existing ones, or stop accepting Medicare altogether. What matters to you is whether your specific doctor accepts it — and you need to know this before you schedule an appointment or switch doctors.

Some doctors do accept Medicare but limit how many Medicare patients they see. Others accept it for established patients but not new ones. A few accept Medicare only for certain types of care. The rules are different depending on whether your doctor is participating (signed an agreement with Medicare) or non-participating (did not sign). Both types can legally refuse Medicare patients, but the financial rules work differently for each.

Key Takeaways

  • Doctors are not required to accept Medicare, and many limit or refuse Medicare patients entirely.
  • Participating doctors have signed an agreement with Medicare and charge set rates; non-participating doctors have not and can charge more.
  • You should confirm your doctor accepts Medicare before scheduling, because "accepts insurance" does not always mean Medicare.
  • If your doctor stops accepting Medicare, you will receive written notice and have time to find a new doctor before coverage ends.
  • Some doctors accept Medicare for some services but not others, so ask specifically about the care you need.

The difference between participating and non-participating doctors

A participating doctor has signed a contract with Medicare agreeing to accept Medicare payment as full payment for covered services. They charge the Medicare-approved amount, and you pay your share (copay, coinsurance, or deductible). They bill Medicare directly. Participating doctors can still refuse to take new Medicare patients, but if they do accept you, the costs are predictable.

A non-participating doctor has not signed a Medicare contract. They can charge more than the Medicare-approved amount — up to 15% more under the Medicare limiting charge rule. You pay the difference out of pocket. Non-participating doctors can also refuse Medicare patients entirely. Some non-participating doctors will not bill Medicare at all and ask you to pay upfront and seek reimbursement yourself.

You can search for participating doctors on Medicare.gov using the "Care Provider Search" tool. It shows you which doctors in your area accept Medicare and whether they are accepting new patients. Non-participating doctors may not appear in this search, so if your current doctor is not listed, ask them directly whether they accept Medicare and at what rate.

Why some doctors limit or refuse Medicare patients

Doctors cite several reasons for not accepting Medicare. Medicare payment rates are often lower than private insurance rates, and the paperwork and billing rules are complex. Some doctors say the reimbursement does not cover the cost of care. Others have reached their patient capacity and choose to fill openings with privately insured patients. A few refuse Medicare on principle, disagreeing with government involvement in healthcare.

Specialists are more likely than primary care doctors to refuse Medicare. Cardiologists, orthopedic surgeons, and dermatologists in some areas have long waiting lists and can afford to be selective. Primary care doctors in rural areas or underserved neighborhoods are more likely to accept Medicare because they serve populations with fewer other options.

The availability of Medicare doctors varies sharply by location. In some cities, most doctors accept Medicare. In others, especially rural areas, finding a Medicare-accepting doctor can take weeks. If you are moving or changing doctors, call ahead to confirm acceptance before you need care.

What to do if your doctor does not accept Medicare

If your doctor does not accept Medicare, you have three options: pay out of pocket, find a different doctor, or ask your doctor to refer you to someone who does accept Medicare.

Paying out of pocket means you pay the full bill to your doctor and then submit a claim to Medicare yourself. Medicare will reimburse you for its share of the approved amount, but you will not know in advance what that share is. You may end up paying more than you would with a participating doctor. This works only if you can afford to pay upfront.

Finding a new doctor takes time but gives you predictable costs. Use Medicare.gov's Care Provider Search or call your Medicare plan to ask for in-network doctors near you. Ask specifically: "Do you accept Medicare?" and "Are you accepting new Medicare patients?" Do not assume a doctor accepts Medicare just because they accept insurance.

If you have a strong relationship with a non-participating doctor, ask whether they will make an exception for you or whether they know a participating doctor they trust. Some doctors will negotiate or refer you to a colleague who accepts Medicare.

What happens if your doctor stops accepting Medicare

If your doctor has been accepting Medicare but decides to stop, Medicare requires them to give you written notice at least 30 days in advance. The notice must tell you the date they will stop accepting Medicare and give you time to find a new doctor.

During the notice period, your current doctor must still accept Medicare for your care. After the notice period ends, they can refuse new Medicare patients and may ask existing Medicare patients to transition to a new provider. Some doctors will see you through the end of a course of treatment (like finishing cancer therapy) even after the notice period, but you cannot count on this — ask.

If you lose your doctor this way, contact your Medicare plan or use Medicare.gov to find a new one. If you are in the middle of treatment, ask your current doctor for a referral and your medical records so the new doctor can continue your care without delay.

How to confirm your doctor accepts Medicare before you schedule

The safest approach is to confirm in writing or by phone before your first appointment. Call your doctor's office and ask: "Do you accept Medicare?" If they say yes, ask: "Are you accepting new Medicare patients?" and "Do you accept Medicare for [the specific service you need]?"

Write down the name of the person who answered and the date you called. If there is a dispute later about whether your doctor accepts Medicare, this record protects you.

You can also check Medicare.gov's Care Provider Search tool, which lists participating doctors and shows whether they are accepting new patients. If your doctor appears there, they accept Medicare. If they do not appear, that does not mean they refuse Medicare — they may be non-participating — so call to confirm.

If you are switching from another doctor, ask the new doctor's office to confirm they have received your medical records before your appointment. This prevents delays if there is any confusion about whether they will see you.

What to ask your doctor about Medicare acceptance

Before you schedule or switch doctors, ask these questions:

  • Do you accept Medicare?
  • Are you a participating or non-participating Medicare provider?
  • Are you accepting new Medicare patients?
  • Do you accept Medicare for [the specific service I need — like surgery, mental health care, or physical therapy]?
  • If you are non-participating, what is your fee, and what will I owe out of pocket?
  • Do you bill Medicare directly, or do I pay you and bill Medicare myself?

Write down the answers. If you later receive a bill that does not match what you were told, you have a record to reference.

Frequently Asked Questions

Can a doctor refuse to see me if I have Medicare?

Yes. A doctor can refuse to accept you as a new patient if you have Medicare, and they can refuse Medicare patients entirely. They cannot refuse to treat you in an emergency, but for routine or scheduled care, they can turn you away. The only exception is if you are already an established patient — then they must give you 30 days' notice before stopping Medicare coverage.

What if I cannot find a Medicare doctor in my area?

Call your Medicare plan's customer service line and ask for help finding an in-network doctor. If your area has very few Medicare doctors, ask whether your plan covers out-of-network care or whether they can help you find a doctor in a nearby town. Some rural areas have telehealth options through Medicare that may help bridge the gap.

Do I have to pay more if my doctor is non-participating?

Possibly. A non-participating doctor can charge up to 15% more than the Medicare-approved amount. You pay the difference out of pocket. A participating doctor charges only the Medicare-approved amount, and you pay your copay or coinsurance. If cost matters to you, choose a participating doctor.

Can my doctor drop me as a patient because I have Medicare?

Not without notice. If you are an established patient, your doctor must give you written notice at least 30 days before they stop accepting Medicare. During those 30 days, they must still see you and accept Medicare payment. After 30 days, they can refuse to see you, but they must give you time to find a new doctor and transfer your records.

What should I do if my doctor's office says they accept Medicare but then bills me for the full amount?

Contact your Medicare plan and file a complaint. Keep the bill and the record of when you called to confirm they accept Medicare. Medicare investigates billing disputes, and if the doctor was supposed to accept Medicare, they may have to refund you. You can also contact your state's insurance commissioner's office for help.
