About 21435: Complicated LeFort III fracture fixation
Reports open operative repair of a complicated LeFort III craniofacial separation when internal and/or external fixation is used to stabilize the fracture.
This service treats a severe LeFort III pattern, in which the midface is separated from the cranial framework. The surgeon exposes and repositions the fracture and stabilizes it with internal fixation, external fixation, or both. Oral and maxillofacial surgeons, plastic surgeons, otolaryngologists, and other surgeons with craniofacial trauma expertise may perform the repair, commonly in a hospital operating room after major facial trauma.
Select this code when the documented injury and operative work support the complicated open-treatment level and internal and/or external fixation. The operative report should identify the craniofacial separation, the repair performed, and the fixation used; use the related code distinctions for wiring or splinting and for multiple approaches. CMS assigns a 90-day global period, including the day-before preoperative visit and related postoperative care during that period. When multiple procedures occur in the same session, the highest-valued is paid in full and the others at 50%. Modifier 50 is inappropriate for this service. Assistant-at-surgery payment may be made; co-surgeons and team surgery are not permitted.
