Some doctors accept Medicare, but they don’t take Medicare assignment with Medicare. In those cases, they can bill the patient more than the Medicare-approved amount, called an excess charge.

It is not likely that you would see excess charges. Less than 5% of healthcare providers are not-participating providers for Medicare. An excess charge is capped at 15% above the Medicare-approved amount for a procedure or service.

How Common Are Excess Medicare Charges?

Excess charges are calculated based on the Medicare-approved amount. For example, suppose you have a medical procedure with a dermatologist to remove a sunspot. Let’s assume the approved amount is $250.

The healthcare provider can charge 15% percent more than the approved amount. 15% of $250 is $37.50. The doctor could charge $287.50. If you have already reached your Medicare Part B deductible, Medicare will pay $200, and you would be responsible for $87.50.

Avoiding being overbilled is one of the most straightforward processes involved with Medicare.
