Which term refers to a method of billing that allows services provided by support staff under a physician’s supervision?

The term that refers to a method of billing allowing services provided by support staff under a physician’s supervision is known as "incident to billing." This billing method is designed to enable healthcare providers, such as nurse practitioners or physician assistants, to deliver services that are considered part of the physician's overall care to a patient, as long as these services are provided in the presence of the supervising physician.

Under incident to billing, support staff can perform certain services that can be billed as if the physician performed them, thus allowing the physician to receive full reimbursement for those services. This method helps in increasing the efficiency of healthcare delivery while still ensuring that patient care is managed by the supervising physician.

The other options do not accurately describe this specific billing method. While "supervised billing," "support service billing," and "delegated billing" may imply some form of collaboration or integration within a healthcare setting, they do not capture the precise regulatory framework and requirements that define incident to billing. Hence, incident to billing is the correct and recognized term in this context.
