We do a percutaneous tenotomy of autologous platelet rich plasma to various joints. Could you please let me know if I am billing correctly or if I should have different codes??? For the shoulder; we would use 36514 for the plasma, A4649 for our surgical tray, 23405 for the percutaneous tenotomy and if we use ultrasound guidance for needle placement we would use 76942. Does this look correct to you? I am too new to feel confident on this one. We would also use it for elbow, knee and heel, cervical facet, thoracic facet and lumbar facet injection types. Looking for any help I can get on this one. Thanks.
