What 21337 covers
An otolaryngologist, facial plastic surgeon, or other physician treating facial trauma reports this service for closed management of a nasal septal fracture. Treatment may include manipulating the fractured septum into position, but manipulation is not required. Care may occur in an office or facility, depending on the injury and treatment setting.
Select the code based on the septal fracture and closed approach, rather than whether manipulation was performed. The record should identify the fracture and describe the treatment provided. This major-surgery service has a 90-day global period, including the day-before preoperative visit and related postoperative care during that 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. Do not append modifier 50. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.
