What doctors say about Medicare Advantage

Many doctors limit or refuse to accept Medicare Advantage plans because of how those plans pay them and control which treatments they can offer. Unlike Original Medicare, which lets doctors bill Medicare directly for most services, Medicare Advantage plans act as middlemen. They set their own payment rates (often lower than Medicare), require prior approval before many procedures, and can deny or delay care that the doctor thinks is medically necessary.

A doctor's frustration with Medicare Advantage usually comes down to three things: less money per patient, more paperwork to get approval, and less control over treatment decisions. When a cardiologist wants to order an imaging test or a surgeon wants to schedule a procedure, a Medicare Advantage plan may say no or demand extra documentation before saying yes. That delay can matter to the patient, and it creates friction between the doctor and the insurance company.

This is not a secret complaint. Major medical organizations, including the American Medical Association, have publicly stated that Medicare Advantage plans create barriers to care. Individual doctors often tell patients directly: "I don't take that plan because I can't give you the care you need without fighting the insurance company first."

Key Takeaways

  • Medicare Advantage plans pay doctors less per visit or procedure than Original Medicare does, which is why some doctors choose not to participate.
  • Medicare Advantage plans require prior approval for many treatments, imaging tests, and specialist visits, adding delays that doctors say interfere with patient care.
  • If your doctor does not accept your Medicare Advantage plan, you may have to switch doctors, pay out of pocket, or switch to Original Medicare during the next enrollment period.
  • Doctors who do accept Medicare Advantage often limit how many of those patients they see, so even in-network doctors may not be taking new patients.
  • The restrictions that frustrate doctors also affect you: longer waits for approvals, limits on which specialists you can see, and sometimes denial of treatments your doctor recommends.

How Medicare Advantage plans pay doctors differently

Original Medicare is a fee-for-service system: the doctor performs a service, bills Medicare, and Medicare pays a set amount. The doctor knows the payment rate in advance. Medicare Advantage plans, by contrast, negotiate their own rates with doctors and hospitals. Those rates are often 10 to 20 percent lower than what Original Medicare pays for the same service.

Some Medicare Advantage plans also use capitation, a payment model where the doctor receives a fixed monthly amount per patient, regardless of how many visits or tests that patient needs. If the patient requires expensive care, the doctor's income stays the same. This creates a financial incentive to limit services, which doctors say puts them in an impossible position: provide less care to protect their income, or provide the care they think is right and lose money.

Doctors in rural areas and small practices are hit hardest. A solo practitioner or a small group cannot absorb lower payment rates the way a large hospital system can. Many straightforward decide the administrative burden and lower pay are not worth it and stop accepting Medicare Advantage altogether.

Prior approval requirements and treatment delays

Before a Medicare Advantage plan will pay for many procedures, imaging tests, specialist visits, or medications, the doctor must get prior approval from the plan. This means the doctor's office calls the insurance company, describes the medical reason for the treatment, and waits for an answer. The process can take hours or days.

Doctors say this system delays necessary care. A patient with chest pain may need a cardiac catheterization, but the Medicare Advantage plan may deny the request or ask for additional testing first, even though the doctor has already determined it is medically necessary. The doctor must then appeal, provide more documentation, and wait again. Meanwhile, the patient's condition may worsen.

Original Medicare has far fewer prior approval requirements. A doctor can order most tests and procedures and bill Medicare afterward. The payment is made or denied based on whether the service was medically necessary, not based on a plan's predetermined list of approved treatments. Doctors say this difference alone is reason enough to avoid Medicare Advantage.

Network restrictions and specialist access

Medicare Advantage plans maintain networks of doctors and hospitals, similar to HMO or PPO plans. Your doctor must be in the network for you to receive covered care at an in-network cost. If your current doctor does not accept your plan, you must either switch doctors or pay out of network (which is usually much more expensive).

Many doctors refuse to join Medicare Advantage networks at all, which shrinks the network and limits your choices. Even doctors who do join often stop taking new Medicare Advantage patients once they reach a certain number. This means you may find your doctor is in-network but not accepting new patients with your plan.

Specialist access is another flashpoint. Some Medicare Advantage plans require you to see your primary care doctor first and get a referral before seeing a specialist. Original Medicare lets you see most specialists without a referral. Doctors say these gatekeeping rules delay diagnosis and frustrate both patients and specialists.

Denial of care and appeals

When a Medicare Advantage plan denies a treatment, the doctor and patient must appeal. The appeal process is slower than the original approval process, and there is no may provide the plan will reverse its decision. A doctor may believe a patient needs a surgery, but the plan says it is not medically necessary according to their criteria. The patient then faces a choice: accept the plan's decision, pay out of pocket, or pursue a lengthy appeal.

Doctors say this puts them in an ethical bind. They took an oath to act in the patient's best interest, but the insurance company is telling them no. Some doctors will fight the appeal; others will tell the patient they need to switch plans or pay privately. Either way, the patient suffers.

Original Medicare denies far fewer claims, and when it does, the appeals process is more straightforward. Doctors say this is one reason they prefer it: fewer fights with the insurance company means more time spent on patient care.

What this means for you as a patient

If your doctor does not accept your Medicare Advantage plan, you have several options. You can switch to a different doctor who does accept the plan, though this may mean leaving a doctor you trust. You can pay out of pocket for visits and procedures, though this can be expensive. Or you can switch to Original Medicare during the next open enrollment period, though you will lose any extra benefits your Medicare Advantage plan offered (like dental or vision coverage).

Even if your doctor does accept your Medicare Advantage plan, you may experience delays in getting approvals for tests or procedures. Your doctor's office will handle the prior approval request, but you should know it may take several days. If the plan denies a treatment, ask your doctor whether they will appeal and what the timeline looks like.

The restrictions that frustrate doctors also affect your out-of-pocket costs. Medicare Advantage plans often have lower premiums than Original Medicare, but they may have higher copays, coinsurance, and deductibles. If you need a lot of care, those costs can add up quickly.

Why some doctors still accept Medicare Advantage

Not all doctors refuse Medicare Advantage. Some accept it because they want to serve Medicare patients and believe they can work within the system. Others accept it because the plan's payment rate, while lower than Original Medicare, is still acceptable. Large medical groups and hospital systems often accept multiple Medicare Advantage plans because they have the administrative staff to handle prior approvals and appeals.

Doctors who accept Medicare Advantage often say they do so reluctantly. They accept it to keep patients, but they may limit how many Medicare Advantage patients they see. This is why you may find a doctor is in-network but not taking new patients with your plan.

Frequently Asked Questions

Can my doctor drop me from their practice if I have Medicare Advantage?

No, not straightforward because you have Medicare Advantage. However, a doctor can stop accepting Medicare Advantage plans altogether and give existing patients time to find a new doctor. If your doctor stops accepting your specific plan, they must give you written notice and a reasonable period to transition to another provider.

What should I do if my doctor does not accept my Medicare Advantage plan?

Contact your plan to find in-network doctors in your area. Ask whether your current doctor might accept your plan if you switch to a different Medicare Advantage plan during open enrollment. If you want to keep your current doctor, ask whether switching to Original Medicare is an option for you.

Will switching to Original Medicare cost me more?

Original Medicare has a monthly Part B premium, but no plan premium. You will pay copays and coinsurance for services. Medicare Advantage plans often have lower or no premiums but may have higher copays and deductibles. The total cost depends on how much care you use and which plan you choose.

Can a Medicare Advantage plan deny a treatment my doctor recommends?

Yes. Medicare Advantage plans can deny coverage if they determine the treatment is not medically necessary according to their criteria. Your doctor can appeal the denial, and you have the right to request an independent review if the plan upholds its decision.

Why do Medicare Advantage plans have these restrictions if they frustrate doctors?

Medicare Advantage plans use prior approval and other controls to manage costs. The plans argue these measures prevent unnecessary care and keep premiums low. Doctors argue the restrictions sometimes prevent necessary care and create delays that harm patients.
