True or False: The supervising physician does not need to be on-site when billing incident-to services.

Billing for incident-to services requires that the supervising physician be present in the office suite when the services are performed. This requirement is in place to ensure proper oversight and to confirm that the non-physician practitioner (NPP) is acting under the physician's direct supervision. The presence of the supervising physician not only supports the billing process but also ensures that the patient receives appropriate care and oversight. If the physician is not on-site, the incident-to billing guidelines cannot be met, and the services may need to be billed differently. For these reasons, the statement that the supervising physician does not need to be on-site is false.

Other options presented, such as special circumstances for emergency services or the experience of the NPP, do not alter the fundamental requirement for physical presence when billing incident-to services.
