About 42845: Radical oropharyngeal resection with graft closure
Reports radical removal of tonsillar or related oropharyngeal tissue when the resulting defect requires closure with a free skin graft.
An otolaryngologist or head-and-neck surgeon may report this extensive operation for disease involving the tonsil, tonsillar pillars, or retromolar trigone. The surgeon removes the involved tissue and closes the resulting defect using a free skin graft. It is typically performed in an operating room, often for an extensive oropharyngeal tumor that cannot be managed with a limited lesion excision. The operative report should identify the resected structures and describe the graft closure.
Choose this code when the documented resection and closure meet this extensive procedure level; a smaller excision or a resection closed without a free skin graft belongs to a different code. Medicare includes the day-before preoperative visit and 90 days of related postoperative care in the 90-day global period. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate for this code. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
