For many physician practices, “incident-to” billing can look like a straightforward way to structure care delivered by non-physician practitioners (NPPs). But the Medicare rules are more nuanced than simply having a physician somewhere in the practice. When the requirements are not satisfied, a practice can face claim denials, repayment demands, and potentially broader compliance concerns.
Under Medicare Part B, services furnished by certain NPPs may be billed as “incident to” a physician or other qualifying practitioner when specific requirements are met. In general, the services must be an integral part of the patient’s normal course of treatment, the physician or other practitioner must have personally performed the initial service and remain actively involved in the course of treatment, and the service must satisfy supervision and additional requirements.
One of the most important requirements is supervision. For traditional incident-to services, CMS requires direct supervision by a physician or other listed practitioner, meaning the supervising practitioner must meet the applicable supervision standard when the service is furnished. CMS also states that only the practitioner who provides the required supervision may bill the incident-to service. That requirement can create operational problems for otherwise well-run practices.
