What Are Medicare Part B Excess Charges and How Can You Avoid Them?

Medicare beneficiaries may be hit with Medicare Part B excess charges when they receive health care services or access durable medical equipment (DME) from providers who don’t accept Medicare assignment. While most physicians and medical facilities accept Medicare assignment - the Medicare-approved amount - as full payment for their services, those who don’t are allowed to charge up to 15% more. This additional charge above the Medicare-approved amount is called a Medicare Part B excess charge. In order to avoid these fees, kupuna on Medicare should confirm that the health care provider or DME supplier accepts Medicare assignment before receiving services or renting/purchasing products. The other option is to enroll in a Medigap plan that covers the excess charges.

What are Medicare Part B excess charges vs regular Part B charges?

Medicare Part B is medical insurance that covers outpatient medical care such as doctor’s visits and DME. It comes with a monthly premium and deductible. In 2022 the standard monthly premium is $170.10 and the deductible is $233. After enrollees meet their deductible, they typically pay 20 percent coinsurance of the Medicare-approved amount for outpatient services and durable medical equipment.

Some healthcare providers accept Medicare insurance but choose not to accept Medicare assignment, in some cases because the Medicare-approved reimbursement amount is lower than what they charge for the treatment. Part B excess charges are only assessed when patients visit a health provider or DME supplier that doesn’t accept Medicare assignment.

The good news is that Part B excess charges are not very common because about 95% of healthcare providers, physicians, and medical suppliers accept Medicare assignment. The remaining 5% who don’t accept it are limited to a 15% surcharge. There are eight states that have laws prohibiting Medicare Part B excess charges but Hawaii is not one of them:

· Connecticut

· Minnesota

· Ohio

· Pennsylvania

· Rhode Island

· Vermont

· Massachusetts

· New York

Here is an example of how Medicare Part B excess charges work:

A Medicare recipient receives medical treatment from a health care provider that does not accept Medicare assignment for a service that has a Medicare approved amount of $200. The doctor can then charge up to an additional 15% over that amount, increasing the total to $230.

Assuming that the patient has met their Part B deductible for the year, they will be responsible for a 20% coinsurance of the Medicare-approved amount plus the full excess charge. In this case that would be $40 coinsurance + $30 excess charge for a total out-of-pocket expense of $70. If that same service had been received by a healthcare provider who did accept Medicare assignment, the patient responsibility would drop to $40.

Medigap plans that cover Part B excess charges

Apart from checking in advance to make sure that the doctor or DME supplier accepts Medicare assignment, the best way to avoid Part B excess charges is to enroll in a Medigap / Medicare Supplement Insurance plan that covers these charges.

For seniors who are looking for coverage of Part B excess charges, there are two options: Medigap plan F (for beneficiaries eligible before January 1, 2020) and Medigap Plan G.

Medicare Advantage plans (Medicare Part C) do not cover Part B excess charges but they do include an annual out-of-pocket spending limit that could help prevent members from paying Part B excess charges past a certain amount.
