Ohio Revised Code Title XLVII. Occupations Professions § 4730.22

(A) When performing authorized services, a physician assistant acts as the agent of the physician assistant's supervising physician. The supervising physician is legally responsible and assumes legal liability for the services provided by the physician assistant.

The physician is not responsible or liable for any services provided by the physician assistant after their supervision agreement expires or is terminated.

(B) When a health care facility permits physician assistants to practice within that facility or any other health care facility under its control, the health care facility shall make reasonable efforts to explain to each individual who may work with a particular physician assistant the scope of that physician assistant's practice within the facility. The appropriate credentialing body within the health care facility shall provide, on request of an individual practicing in the facility with a physician assistant, a copy of the facility's policies on the practice of physician assistants within the facility and a copy of each supervision agreement applicable to the physician assistant.

An individual who follows the orders of a physician assistant practicing in a health care facility is not subject to disciplinary action by any administrative agency that governs that individual's conduct and is not liable in damages in a civil action for injury, death, or loss to person or property resulting from the individual's acts or omissions in the performance of any procedure, treatment, or other health care service if the individual reasonably believed that the physician assistant was acting within the proper scope of practice or was relaying medical orders from a supervising physician, unless the act or omission constitutes willful or wanton misconduct.
