Platelet rich plasma injection

With the addition of the new Category III code, coding for it seems even more confusing.

If a patient has a tenotomy of the obturator (hip adductor) under ultrasound guidance followed by a tendon injection of PRP with ultrasound, would it be correct to bill 27000, 76942, 0232T?

If the patient has only an injection of PRP into the knee joint, would the appropriate coding be only 0232T?

Thank you!
