Step-by-step explanation:
In the context of physical therapy documentation, Pt. qh most likely stands for patient quarter hour. This abbreviation is often used to indicate the frequency of therapy services provided to the patient. For instance, if physical therapy services are scheduled every quarter hour, it means the patient is receiving therapy in 15-minute increments. This is a common way to schedule and bill for physical therapy services, ensuring that the patient's care plan is followed with precision and that the service durations are accurately recorded for both clinical and administrative purposes.
