What 21347 covers
This service is open surgical repair of a LeFort II-pattern fracture involving the central midface, including the nasal and maxillary structures. The surgeon exposes and reduces the fracture through multiple operative approaches. Oral and maxillofacial surgeons, facial plastic surgeons, and otolaryngologists may perform the repair, commonly in a hospital operating room after significant facial trauma.
Choose this code when the operative report supports the fracture pattern and use of multiple approaches; the number of approaches, not simply the number of fracture lines, distinguishes it from related repair codes. Document the injury, reduction, and approaches used. CMS assigns a 90-day global period, including the day-before preoperative visit and related postoperative care. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and others at 50%. Modifier 50 is inappropriate. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

21347 billing questions
How is 21347 distinguished from 21346?
21347 is selected when the open repair uses multiple surgical approaches. Code 21346 describes a related open repair with fixation; follow the specific operative service documented.
Does multiple approaches mean multiple fracture lines?
No. The distinction is the use of multiple operative approaches to expose and repair the nasomaxillary fracture, not merely the presence of multiple fracture lines.
Can modifier 50 be reported when both sides are involved?
No. CMS identifies bilateral adjustment as inappropriate for this code, even when the injury involves both sides.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
Can an assistant or co-surgeon be reported?
An assistant at surgery may be paid. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
