Many people who are new to Medicare, and even those who have been enrolled for years often as “Can a doctor refuse a Medicare supplement plan if you visit them?” The answer is, possibly.

But as long as you know the basic rules ahead of time, you’ll be left with no surprises when it comes to using your Medicare supplement plan through your doctors.


Doctors must accept Original Medicare

There are doctors that simply refuse to participate in Medicare due to the stringent rules, paperwork, and low reimbursement rates from Medicare.

Medicare usually pays around 80% of what doctors can charge private healthcare insurers for their services. So, it’s unsurprising that some avoid accepting Medicare “assignment” rates.

Doctors state Medicare reimbursements haven’t kept pace with annual inflation increases in recent years, forcing many of them to refuse to accept Medicare rates as payment for services rendered. While this is a fact, the regulations surrounding the healthcare industry keep tightening, and there are stiff penalties for noncompliance.


Using your Medicare Supplement Plan

As long as the provider you are seeing accepts Original Medicare (regardless of if they accept the assigned rates or not), then they will accept your Medigap plan. If they do not accept Medicare, then there is nothing to supplement.

And because Medigap plans work alongside Medicare Parts A and B, and do not replace those parts, then doctors must accept Medicare for you to use your supplemental insurance. There are no exceptions to this.

If a doctor accepts Medicare and Medigap plans, they cannot pick and choose which Medicare supplement companies they wish to accept. Whether it’s an Allstate Medigap plan or a supplement plan from Mutual of Omaha, they must take either one.

Medicare Parts A and Part B

There is No Network

Because Medicare is a federal program and is used nationwide, and Medicare supplements follow Medicare, there is no network when it comes to using your Medigap plan.

You may visit any doctor, specialist, or hospital that accepts Medicare and provide them with your Medicare Supplement insurance.

So unless the provider’s office does not accept Medicare patients, or in rare cases, they only accept a certain Medicare Advantage plan, then they cannot refuse to accept your Medicare Supplement plan.

What are Medicare Supplement Plans?

The Federal government standardizes the Part A & B benefits offered in Medigap plans. This regulation ensures consistency in the benefits offered across all providers.


All Medigap plans offer the following benefits.

  • Part A coinsurance and hospital costs for up to 365 days after using up Medicare benefits.
  • Part A hospice care coinsurance or copayment.
  • Part B coinsurance or copayment.
  • Blood transfusion costs for the first three pints of blood.


Plans F, G, and N offer additional Medicare Parts A & B benefits.

  • Part A deductible.
  • Part B excess charges (Plan N doesn’t cover these charges).
  • Skilled nursing facility care coinsurance.
  • 80% of emergency healthcare costs when traveling outside the US for 60 days. ($250 deductible and $50,000 maximum apply).
  • Unlimited coverage for all out-of-pocket costs.


Medigap plans don’t cover the costs of vision, hearing, and dental services. However, some insurers offer discounted rates on these services from providers in their network. Or they may include a separate policy covering these services for a small monthly fee.

Medigap policies also don’t cover the costs of private-duty nursing, stays at long-term nursing homes, or preventative services like foot care, physiotherapy, and chiropractic. Medigap also doesn’t cover the cost of prescriptions – you’ll need Part D for that.

What is Medicare Assignment?

Most doctors accept “Medicare Assignment” rates for their services without an excess charge. However, doctors have the right to charge 15% above the Medicare-nominated rate for consultations and treatments. As a result, you’re responsible for the additional costs to pay out-of-pocket.

Although Medicare Part B excess charges are extremely rare, you can be safe by enrolling in one of the most popular plans such as Medigap Plans F & G. Both of these offer coverage for these Part B excess charges, leaving you with nothing to pay. The rest of the Medigap policies don’t cover Part B excess charges, but these charges are rare and typically very inexpensive.

If you’re on plans other than Plans F & G, such as the very popular Medigap Plan N, you can simply avoid excess charges by using a physician who accepts Medicare Assignment rates. It’s estimated that over 95% of doctors in the United States do not charge Part B excess charges.

How to Find Doctors Who Accept Medicare

Many doctors charge Medicare Assignment rates, and you can locate participating providers close to your using the Medicare Physician Compare Directory.

This comprehensive list of healthcare providers and doctors gives you plenty of options around your local area. After locating a provider, call their office to ensure they still accept Medicare Assignment before booking your appointment.

Plan N Doesn't Cover Part B Excess Charges

Plan N doesn’t cover the Part B excess charges involved with seeing a doctor charging more than Medicare assignment rates. You’re liable for the additional charges if you see physicians working outside this rate.

These are quite rare, and on average less than 1% of all claims typically include Part B excess charges. If you use a doctor that accepts Medicare assignment, you will not be billed any excess charges.

If a Doctor does not Accept Medicare Assignment

Your doctor may decide that they don’t agree with Medicare’s reimbursement rates but still accept Medicare patients. In this case, they’ll charge their services at a rate 15% above the Medicare-approved amount. These physicians are “non-participating providers.” The extra fees they charge are called “excess charges.”

As mentioned, Plans F & G pay for these additional excess charges. However, the other plans require you to pay the excess out-of-pocket. You’ll also have to pay the doctor’s fee upfront and then get Medicare to reimburse you. Your doctor submits your claim to Medicare on your behalf, or you’ll have to do it yourself using claim Form CMS-1490S.

For instance, your doctor’s bill comes to $300 for your consultation. Medicare pays a rate of $250, leaving you with an excess charge of $50 unless you have Plans F or G (Plan N also requires you to make a $20 copayment).

Ask the Doctor for a Referral

Medicare and Medigap policies don’t institute excess charges or copayments for visits to urgent care facilities across the United States. As a result, many seniors now use the urgent care center for their healthcare evaluations and assessments.

There are over 9,000 urgent care centers across America, and there’s probably one near your home. Many urgent care centers operate as “walk-in” clinics. That means you don’t make an appointment, you arrive, and the team treats you on a “triage” basis, attending to the most critical patients first.

So, you might have to wait a while for your consultation and treatment, but you won’t have any Part B excess charges to pay for these services.

For those who have Medigap Plan N, which typically requires a $50 copay if you visit the emergency room and you’re not admitted, Urgent care centers do not charge this copay.

Medigap Plan N doesn’t provide coverage for your prescription medications. However, it does cover pain relief medications in hospices and respite care in skilled nursing facilities, with a $5 copayment. You must take the additional Part D plan if you want drug coverage.
