The particular surgery in question is done by two sets of surgeons. Panel 1 is the one I am coding for. They performed a mod rad neck dissection 38724, pectoralis major flap 15732 and lower border mandibulectomy for vascular access. This part was done so the other surgeons could do a carotid artery resection. Nothing was done to the bone for the removal of lesions, cysts or other osteo issues, just to remove some bone that was in the way. Can this be billed or would it be included with other procedures? The other coder in the office wants to use 21044 removal of malignant neoplasm of mandible. I Would love your insight. Thanks
