What Are Medicare Part B Excess Charges?

Healthcare providers generally accept Medicare assignment. Meaning, they agree with Medicare’s payment terms and rates and bill Medicare accordingly.

How Medicare Part B Excess Charges Work

Let’s say you visit a nonparticipating podiatrist to get a wart removed from your foot. If the Medicare allowable charge for the procedure is $300, the podiatrist could bill you up to an additional $45. Making the total cost for the procedure, $345. If you’ve already met the Part B deductible, your out of pocket costs would be $45 in addition to the 20% coinsurance. 20% of $300 is $60. Therefore, your total out of pocket cost for the procedure would be $105.

How to Avoid Part B Excess Charges

The most obvious way to avoid Part B excess charges is by only visiting doctors who accept Medicare Assignment. The easiest thing you can do is simply ask them if they accept assignment upon scheduling an appointment.

  1. I was going to go to a doctor (specialist) that accepted Medicare but they asked for more than the medicare deductible allows. What do I do?

    1. Hi Rosemarie! Your provider should not be asking you to pay the deductible, they should be billing everything through Medicare and allow Medicare to bill you for the deductible on their end. Always tell them to bill Medicare, otherwise, they may not have a record that you met the deductible for the calendar year.
