About 21343: Open repair of depressed frontal sinus fracture
Open repair of a depressed frontal sinus fracture, reported when the surgeon surgically exposes and restores the position or contour of the injured sinus region.
This code describes open surgical treatment of a depressed fracture involving the frontal sinus, the air space behind the forehead. The surgeon exposes the fracture and restores the depressed bone’s position or contour. Otolaryngologists, facial plastic surgeons, oral and maxillofacial surgeons, and neurosurgeons may perform this repair, typically in an operating room after facial trauma. The operative report should identify the frontal sinus fracture and describe the open approach and repair performed.
Select this code for the depressed frontal sinus fracture repair rather than a code for a different facial bone or a more complex frontal sinus fracture. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care. 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. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted. The anatomy is not reported with modifier 50.
