d. Therapeutic exercises

Therapeutic exercises which must be performed by or under the supervision of the qualified physical therapist due either to the type of exercise employed or to the condition of the patient constitute covered physical therapy. Range of motion exercises require the skills of a qualified physical therapist only when they are part of the active treatment of a specific disease which has resulted in a loss or restriction of mobility and such exercises, either because of their nature or the condition of the patient, may only be performed safely and effectively by or under the supervision of a qualified physical therapist.
