Yes, Medicare typically pays doctors less per service than private insurance does
Medicare's payment rates for the same medical service are usually 20 to 40 percent lower than what private insurance companies pay. A doctor's office visit, a blood test, or a surgical procedure will generate a smaller check from Medicare than from a private insurer for the same work. This difference is one reason some doctors limit the number of Medicare patients they see, and why understanding how payment works matters if you're on Medicare.
The gap exists because Medicare sets its own payment rates — it does not negotiate with doctors the way private insurers do. Instead, Medicare uses a formula based on the cost of providing care, the time involved, and the complexity of the service. Private insurers often pay more because they compete for patients and doctors, and because they may reimburse based on what they charged before insurance, not on a government-set schedule.
Key Takeaways
- Medicare pays doctors roughly 20 to 40 percent less per service than private insurance companies do for identical care.
- Medicare sets payment rates using a fixed formula; private insurers negotiate rates with doctors and hospitals individually.
- Some doctors accept fewer Medicare patients or stop accepting Medicare altogether because the lower payments do not cover their costs.
- The payment difference does not affect the quality of care you receive — doctors are required to provide the same standard of treatment to all patients regardless of insurance type.
- You may have longer wait times or fewer appointment slots available if your doctor limits Medicare patients due to payment concerns.
How Medicare Sets Its Payment Rates
Medicare uses a system called the Relative Value Unit (RVU) scale to decide what it pays for each service. The RVU assigns a point value to every procedure and visit based on three things: the doctor's work (time and skill), the practice expense (rent, staff, equipment), and malpractice insurance. Medicare then multiplies the RVU by a dollar conversion factor — a number that changes each year — to arrive at the payment amount.
This system is the same nationwide, which means a cardiologist in rural Montana and one in Manhattan receive the same Medicare payment for the same procedure. Private insurers, by contrast, negotiate rates with individual doctors and hospitals, often paying more in high-cost areas and less in low-cost ones. They also have the flexibility to pay more for services they want to encourage or less for services they want to discourage.
Congress sets the conversion factor each year, and it has not kept pace with inflation or the rising costs of running a medical practice. As a result, the gap between Medicare and private insurance payments has widened over time.
Why Some Doctors Limit or Refuse Medicare Patients
When a doctor's overhead — staff salaries, rent, equipment, supplies — stays the same but Medicare payments shrink in real terms, the doctor must see more Medicare patients to earn the same income, or accept lower income. Many doctors choose a third option: they limit the number of Medicare patients they accept, or they stop accepting Medicare altogether.
A doctor who stops accepting Medicare is called non-participating. Non-participating doctors can still see Medicare patients, but they can charge you more than Medicare allows, and you may have to pay out of pocket. A doctor who accepts Medicare is called participating, and they agree to accept Medicare's payment as payment in full for covered services.
The proportion of doctors accepting Medicare has declined in some specialties. Primary care doctors, cardiologists, and orthopedic surgeons in particular have reduced their Medicare patient load in recent years. This can make it harder to find a doctor who accepts Medicare in your area, or lead to longer waits for appointments.
How This Affects Your Care and Costs
The lower payment rates do not mean you receive lower-quality care. Medicare requires doctors to provide the same standard of treatment to Medicare patients as to privately insured patients. A doctor cannot give you a shorter visit, skip tests, or use cheaper medications because you are on Medicare. The payment difference is between the doctor and Medicare, not between you and the doctor.
What the payment difference does affect is availability. If your doctor limits Medicare patients, you may have fewer appointment slots, longer waits, or may need to switch doctors. You may also find that some doctors in your area do not accept Medicare at all, which means you would need to pay out of pocket or find a different provider.
Your out-of-pocket costs — copays, coinsurance, and deductibles — are set by Medicare, not by individual doctors, so the doctor's payment rate does not directly change what you pay at the visit. However, if fewer doctors accept Medicare in your area, you may end up traveling farther or waiting longer, which has its own costs.
Comparing Medicare Payments Across Different Types of Services
The payment gap between Medicare and private insurance varies by service. Some services have a narrower gap; others are much wider. For example, Medicare's payment for a routine office visit is often closer to private insurance rates than its payment for certain imaging or surgical procedures.
Specialists tend to see a larger gap than primary care doctors. A cardiologist or orthopedic surgeon may see a 30 to 40 percent difference between Medicare and private insurance for the same procedure, while a primary care doctor's gap might be closer to 15 to 25 percent. This is one reason specialists are more likely to limit Medicare patients.
Rural areas often have a harder time attracting doctors because Medicare payments are the same everywhere, but the cost of living and operating a practice varies. A doctor in a rural area with lower overhead might still find Medicare payments acceptable, but a doctor in a high-cost urban area may not.
What Happens When a Doctor Stops Accepting Medicare
If your current doctor stops accepting Medicare, you will receive a notice. You then have options: find a new doctor who accepts Medicare, continue seeing your current doctor and pay out of pocket, or ask your doctor to refer you to another provider in the same practice who does accept Medicare.
If you choose to keep seeing a non-participating doctor, you will pay the full bill upfront and then submit it to Medicare for reimbursement. Medicare will pay its share (usually 80 percent of the allowed amount after you meet your deductible), and you will be responsible for the rest. This can be more expensive than seeing a participating doctor, where the doctor accepts Medicare's payment as full payment.
To find doctors who accept Medicare in your area, you can search the Medicare Physician Compare tool on Medicare.gov, or call your local Medicare office. Your current doctor's office can also tell you whether they accept Medicare and whether they are accepting new Medicare patients.
How Medicare Payments Compare to Other Government Programs
Medicaid, the program for lower-income adults and families, typically pays even less than Medicare. Veterans Administration (VA) doctors are salaried employees, so payment rates work differently. TRICARE, the insurance program for military families, pays rates somewhere between Medicare and private insurance.
Because Medicaid pays the least, doctors are even more likely to limit Medicaid patients than Medicare patients. Some doctors accept Medicare but not Medicaid, or accept both but have a cap on how many Medicaid patients they see. This creates a two-tier system where patients on government programs have fewer choices.
Frequently Asked Questions
If Medicare pays my doctor less, does that mean I get worse care?
No. Medicare requires doctors to provide the same standard of care to all patients regardless of insurance type. The payment difference is between the doctor and Medicare, not between you and the doctor. Your care quality is not affected by how much your doctor is paid.
Can my doctor charge me extra if they accept Medicare?
No, if your doctor is a participating provider (accepts Medicare), they must accept Medicare's payment as payment in full for covered services. They cannot balance-bill you for the difference between their usual charge and Medicare's payment. Non-participating doctors can charge you more, but they must tell you in advance.
What should I do if my doctor stops accepting Medicare?
You will receive written notice. You can search for a new doctor using the Medicare Physician Compare tool on Medicare.gov, ask your doctor for a referral, or call your local Medicare office for help finding a provider. If you want to keep seeing your current doctor, you can pay out of pocket and submit the bill to Medicare for reimbursement.
Why does Medicare pay less if it covers more people?
Medicare's lower rates are set by Congress, not determined by the number of patients. Congress controls the conversion factor that Medicare uses to calculate payments, and it has not increased payments as fast as medical costs have risen. Private insurers have more flexibility to adjust rates based on demand and competition.
Are there areas where I might have trouble finding a doctor who accepts Medicare?
Yes, rural areas and some urban neighborhoods have fewer doctors accepting Medicare, especially specialists. If you live in an area with limited options, your local Area Agency on Aging or your State Health Insurance information Program (SHIP) can help you find providers or explore alternatives.
