Medicare part b excess charges

Although it’s not extremely common, occasionally healthcare providers may charge patients with Medicare Part B excess charges after their visits. Over 96% of providers such as doctors, primary care physicians (PCPs), nurse practitioners, etc., choose to accept Medicare and receive the Medicare-approved amount as full payment. However, if a patient does receive a Part B charge, it’s crucial to know how to handle it and potentially avoid them in the future.

What Are Medicare Part B Excess Charges?

The federal Medicare program has allotted price amounts for all services and procedures that they agree to pay. This means, when a patient receives a medical service, their provider must agree to accept Medicare assignment” or agree to the Medicare-approved amount as payment for the service or equipment. From there, the provider sends out an invoice of the cost directly to Medicare where Medicare typically handles 80% of the payment, leaving a patient to pay the remaining 20%. However, if a provider does not accept assignment” they may charge a Part B excess charge of up to 15% more than the Medicare-approved amount.

What is a Medicare Assignment?

When a patient receives a service, their provider has the option to accept assignment.” When a provider accepts a Medicare assignment, it essentially means that the provider agrees to the Medicare-approved service amount and they won’t bill the patient above that rate. The Medicare-approved amount is how much Medicare agrees to reimburse the provider for the given medical service or equipment. At times, the Medicare-approved amount is lower than what a health care provider charges.

When providers choose not to accept assignment, they could charge up to 15% higher than the Medicare-approved amount, leading to excess charges.

What is Medicare Part B?

Medicare Part B refers to the part of Original Medicare or Medicare Advantage (MA) plans that covers medical insurance. Part B insurance requires Medicare beneficiaries to pay a monthly premium of approximately $148.50. All in all, it works to cover various outpatient services such as doctor visits, preventive care, ambulance services, ER visits, durable medical equipment (DME) and more.
