Medicare Part B covers cardiology visits without a referral requirement

No. If you have Medicare Part B, you can see a cardiologist directly without asking your primary care doctor for a referral first. Medicare Part B is hospital insurance that covers doctor visits, and it does not require referrals for any specialist, including cardiologists. You can call a cardiologist's office, schedule an appointment, and go — as long as the cardiologist accepts Medicare.

This is different from many private insurance plans, which do require a referral before you see a specialist. Because Medicare does not, you have the freedom to seek heart care on your own schedule without waiting for your primary doctor to send paperwork.

However, there are two important limits. First, the cardiologist must accept Medicare assignment, meaning they agree to the Medicare fee schedule. Second, you will owe your Part B deductible and coinsurance (usually 20 percent of the approved amount) unless you have a Medigap or Medicare Advantage plan that covers those costs.

Key Takeaways

  • Medicare Part B does not require a referral to see a cardiologist — you can schedule directly with any cardiologist who accepts Medicare.
  • The cardiologist must accept Medicare assignment for your visit to be covered at the standard Medicare rate.
  • You will owe your Part B deductible (if you have not met it) and 20 percent coinsurance unless a Medigap or Medicare Advantage plan covers those costs.
  • If you have a Medicare Advantage plan, check your plan documents first, because some Advantage plans do require a referral or have network restrictions.
  • Calling the cardiologist's office before your first visit to confirm they accept Medicare can save you from unexpected bills.

How to find and schedule with a Medicare-accepting cardiologist

Start by using the Medicare Physician Compare tool on Medicare.gov. Type in your zip code and search for cardiologists. The tool shows you which doctors accept Medicare, their location, and whether they are currently taking new patients. This step prevents you from calling offices that do not accept Medicare or are not accepting new patients.

When you call the cardiologist's office, ask three things: whether they accept Medicare assignment, what your out-of-pocket cost will be, and how long the wait is for a new patient appointment. Some offices can tell you your coinsurance amount right away if you give them your Medicare number. Write down the office's cancellation policy too — if you need to reschedule, you want to know the notice required.

Bring your Medicare card and a photo ID to your first appointment. The office will ask for your insurance information and may ask about your medical history. If you have seen a cardiologist before, ask your previous office to send your records to the new cardiologist so they have your full history.

The difference between Medicare Part B and Medicare Advantage plans

If you have Original Medicare (Part A and Part B), no referral is required. If you have a Medicare Advantage plan (Part C), the rules depend on your specific plan. Some Advantage plans do require a referral to see a cardiologist, and some have a network of doctors you must use. Check your plan's Summary of Benefits or call the plan's customer service number on the back of your card before scheduling.

Medicare Advantage plans often have lower out-of-pocket costs than Original Medicare, but they come with these restrictions. If your Advantage plan requires a referral, you will need to contact your primary care doctor first. The referral process usually takes a few days to a week, and your doctor's office will send it electronically to the cardiologist.

If you are unsure which type of Medicare you have, look at your card. Original Medicare cards say "HEALTH INSURANCE" at the top. Advantage plan cards have the insurance company's name and logo on them.

What to expect for your out-of-pocket costs

With Original Medicare Part B, you owe your annual deductible (the amount you must pay before Medicare starts paying) and then 20 percent of the approved amount for the visit. The deductible amount changes each year — it was $226 in 2024, but confirm the current year's amount on Medicare.gov. Once you meet your deductible, you owe 20 percent coinsurance for each visit.

If you have a Medigap plan (supplemental insurance), it usually covers your deductible and coinsurance, so you may owe nothing at the cardiologist's office. If you have a Medicare Advantage plan, your costs depend on your plan — you might owe a copay (a fixed amount like $40) instead of coinsurance, or you might owe nothing if the cardiologist is in-network.

Ask the cardiologist's office to estimate your cost before your appointment. They can look up what Medicare will approve and calculate what you will owe based on whether you have met your deductible. This estimate is not a bill — it is an educated guess — but it helps you plan.

When your primary care doctor should be involved

Even though you do not need a referral, telling your primary care doctor that you are seeing a cardiologist is a good idea. Your primary doctor can share your medical history with the cardiologist, and the cardiologist can send results back to your primary doctor. This coordination helps both doctors understand your full health picture.

If your primary care doctor recommended that you see a cardiologist, they may have already documented this in your medical record. When you call the cardiologist's office, mention this — it can sometimes speed up scheduling and helps the cardiologist understand why you are coming in.

After your cardiology visit, ask the cardiologist's office to send a summary of the visit and any test results to your primary care doctor. You can also request a copy for yourself. Having these records in one place makes it easier to track your heart health over time.

What happens if the cardiologist does not accept Medicare assignment

Some cardiologists are non-participating providers, meaning they do not accept Medicare assignment. These doctors can still see you, but they may charge more than the Medicare-approved amount. You will owe the difference between what they charge and what Medicare pays, which can be substantial.

Before scheduling with a non-participating provider, ask in writing what they charge for a new patient visit and what Medicare will pay. Then calculate what you will owe out of pocket. In many cases, it is worth the extra effort to find a participating cardiologist who accepts assignment.

If you do see a non-participating cardiologist, Medicare will still pay its share, but you are responsible for any amount above the Medicare-approved fee. Keep all receipts and bills — you may be able to count these costs toward your out-of-pocket maximum if you have a Medigap or Advantage plan.

Frequently Asked Questions

Can I see a cardiologist without seeing my primary care doctor first?

Yes. Medicare Part B does not require a referral, so you can contact a cardiologist directly and schedule an appointment without your primary doctor's permission. However, if you have a Medicare Advantage plan, check your plan documents first — some Advantage plans do require a referral.

What if I need an urgent cardiology appointment?

Call the cardiologist's office and explain that you need an urgent visit. Many offices keep same-day or next-day slots for urgent cases. If you are having chest pain or other emergency symptoms, go to the emergency room instead — do not wait for a scheduled appointment.

Do I need to pay the cardiologist before Medicare pays?

No. The cardiologist's office bills Medicare directly, and Medicare pays its share. You owe your deductible and coinsurance, which the office will bill you for after Medicare processes the claim. This usually takes a few weeks.

What if the cardiologist wants to do tests like an EKG or stress test?

Medicare covers these tests when a cardiologist orders them. You will owe your deductible and coinsurance for the tests just as you do for the visit. Ask the office to estimate the cost of any tests before they are done so you know what to expect.

Can I change cardiologists if I do not like the first one?

Yes. You can see any Medicare-accepting cardiologist you choose. There is no lock-in period. If you want to switch, straightforward call a different cardiologist's office and schedule an appointment. Request that your records be sent to the new cardiologist.
