Incident-to Billing Under Medicare: A Compliance Trap for Otherwise Compliant Practices

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.

Consider a practice in which a nurse practitioner sees established patients throughout the day while the supervising physician is routinely moving between locations. The practice may have excellent documentation, appropriate clinical protocols, and qualified personnel. Yet if the supervision requirements are not satisfied for the services being billed incident to the physician, the practice may have a Medicare billing problem. The risk is magnified because incident-to compliance is not merely a coding issue. Practices should consider whether their scheduling, staffing, supervision, enrollment, documentation, and billing systems all reflect the same underlying arrangement.

A prudent compliance review should therefore ask several basic questions: Who performed the service? Who initiated the patient’s treatment? Is the physician or other qualifying practitioner still actively involved in the course of treatment? Who provided the required supervision? Was the service furnished in an appropriate setting? And does the medical record support the circumstances under which the service was billed?

Practices should also avoid assuming that one supervision rule applies universally. CMS identifies different supervision requirements for certain services, including transitional care management, chronic care management, and behavioral health services furnished incident to a physician or other practitioner.

For physician owners and business leaders, the takeaway is simple: incident-to billing should be treated as an operational compliance process, not merely a billing convention. A practice that regularly uses NPPs should periodically audit whether its actual workflows match Medicare’s billing requirements. A relatively small investment in reviewing supervision, documentation, and billing practices can help identify problems before a contractor does—and can prevent a routine staffing model from becoming a costly Medicare compliance issue.
