About 21452: Percutaneous mandibular fracture external fixation
Percutaneous mandibular fracture treatment using external fixation is reported when the surgeon stabilizes the fracture with an externally applied frame.
Code 21452 describes treatment of a mandibular fracture through a percutaneous approach, using pins connected to an external stabilizing frame. An oral and maxillofacial surgeon or another surgeon managing facial trauma typically performs this operative stabilization in a surgical setting. The defining feature is external fixation placed percutaneously, rather than fracture exposure with internal fixation or stabilization by interdental wiring.
Report the code when the operative documentation identifies the mandibular fracture and supports percutaneous placement and use of external fixation. The 90-day major-surgery global period includes the day-before preoperative visit and 90 days of related postoperative care. When other procedures are performed in the same session, the highest-valued procedure is paid in full and the others at 50%. Modifier 50 is inappropriate. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.
