The PT who is treating and/or delegating and supervising the treatment of a patient holds the primary responsibility for all of the ensuing physical therapy treatment that is rendered. Professional responsibilities of that PT include, but are not limited to, the performance and documentation of the initial physical therapy examination/evaluation of the patient, the development and documentation of a plan of care based on that evaluation, and performance and documentation of the reexamination/reevaluation of the patient.
If a treating/supervising PT chooses to accept the evaluation/reevaluation of a patient performed by another PT (regardless of same or different company), the treating/supervising PT is wholly responsible for the care of the patient and any treatment performed by them or under their supervision.
A PTA cannot perform physical therapy treatment without a written plan of care and a designated supervising PT who is on call and readily available to respond in person within a reasonable amount of time if the need arises. To do so would be a violation of the PT Practice Act/Rules and could subject the PTA to disciplinary action.
