Most primary care physicians do accept Medicare.
However, it’s always best to confirm your coverage before any appointment—especially if you’re seeing a specialist. You can do this by calling the doctor’s office with your Medicare details or contacting your Medicare provider directly.

In general, the answer is yes. Around 93% of non-pediatric primary care doctors accept Medicare, which is nearly the same as the 94% who accept private insurance. That said, acceptance may vary depending on your specific Medicare plan and whether you’re already an established patient.

Here’s what to know about Medicare coverage and how to ensure you’re covered.

How to Find a Medicare-Participating Doctor

The official Medicare website provides a search tool called Physician Compare, which helps you locate doctors and facilities enrolled in Medicare. You can also call 800-MEDICARE to speak with a representative.

If you’re enrolled in a Medicare Advantage plan, you can contact your plan provider directly or use their online member portal to find in-network doctors.

These tools usually let you search by:

• Medical specialty or condition

• Body system or organ

• ZIP code or location

• Doctor’s name

• Gender

• Hospital affiliation

Even after using these resources, it’s wise to call the doctor’s office to confirm that they accept Medicare and are taking new Medicare patients.

Why Some Doctors Don’t Accept Medicare

Some doctors opt out of Medicare for financial or administrative reasons. If your provider stops accepting Medicare, you can continue seeing them by paying out of pocket or switch to another doctor who does.

Doctors who haven’t agreed to accept assignment (the Medicare-approved payment amount for services) are called non-participating providers. They’re still enrolled in Medicare but decide individually whether to accept the Medicare-approved rate.

What Happens If Your Doctor Doesn’t Take Medicare

Doctors who fully participate in Medicare can’t charge more than the Medicare-approved amount. Non-participating doctors, however, may charge up to 15% more, known as the limiting charge. Some states cap this at 5%, in addition to the standard 20% coinsurance.

Depending on the office policy, you might need to pay these costs upfront or receive a bill later. Always ask about payment procedures before your visit so you know what to expect.

If you pay out of pocket, you have up to one year to file a claim with Medicare for potential reimbursement.

The Bottom Line

Most doctors accept Medicare, but it’s always wise to confirm before your appointment. If your provider stops participating, ask how it affects your coverage and what steps you can take to stay financially protected.
