Answer: Because the corresponding code recommended by ASA (00640, anesthesia for closed procedures on cervical, lumbar or thoracic spine) is not in CPT, the most appropriate crosswalk code is 00620 (anesthesia for procedures on thoracic spine and cord; not otherwise specified) because the definition of 22520 limits the procedure to the thoracic spine. However, many carriers consider 00620 an open procedure and will not accept it for percutaneous procedure. Then, you would use 01999 (unlisted anesthesia procedure[s]). Because this decision is carrier-specific, make sure to check before you bill.
