CPT Knowledgebase - Feb 6, 2025

Would it be appropriate to report codes 21209, 21215, 21245, 40840, and 42950 in addition to code 20969 if a graft is used to reconstruct both a head and neck defect as in the following scenario? The physician performed a fibula osteocutaneous graft to reconstruct both a head and neck defect (20969). The physician planned a templated graft from the leg for the defect and smoothed the residual mandible to accept the defect. The physician performed a fixation of the graft with a subperiosteal plate and implanted the endosteal implants as part of this procedure. Intermaxillary fixation was applied to secure the mouth in occlusion, and the skin paddle was rotated and closed to perform a partial pharyngoplasty. The physician completed a buccal vestibuloplasty by de-epithelializing a portion of the skin paddle and securing it deep into the vestibule. The bone from the smoothing process was taken to use as a bone graft for any gaps, and the neck was closed with deep and skin sutures.
