A physician assistant shall not assist a physician in a manner not described in the agreement or without the nature and degree of supervision described in the agreement. There shall be no more than six physician assistants for whom a physician has responsibility or supervises pursuant to a written agreement at any time. In health care facilities licensed under the act of July 19, 1979 (P.L. 130, No. 48), known as the Health Care Facilities Act, a physician assistant shall be under the supervision of a physician or physician group pursuant to a written agreement, provided that a physician supervises no more than six physician assistants at any time. A physician may apply for a waiver to employ or supervise more physician assistants at any time under this section for good cause, as determined by the board.
