About 21147: Multi-piece LeFort I reconstruction with graft
Reconstructs the maxilla through a LeFort I osteotomy in three or more segments with bone grafting for complex midface deformity correction.
This service reconstructs the midface by mobilizing the maxilla with a LeFort I osteotomy, dividing it into three or more pieces, and using bone grafting as part of the reconstruction. Oral and maxillofacial surgeons, plastic surgeons, or craniofacial surgeons may perform it in an operating room for complex maxillary deformity, such as a developmental midface discrepancy requiring segmental repositioning.
Select this code when the operative report supports both three or more maxillary segments and bone grafting; the number of segments and graft use distinguish it from neighboring LeFort I codes. The record should describe the osteotomy, segment configuration, reconstruction, and grafting. This major surgery has a 90-day global period that includes the day-before preoperative visit and 90 days of 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. Assistant-at-surgery payment may be available; co-surgeons and team surgery are not permitted.

21147 billing questions
How does this differ from 21143?
Both describe a LeFort I reconstruction in three or more pieces. This code is for the reconstruction with bone grafting; 21143 is the corresponding option without grafting.
How many segments support this code?
The maxilla must be divided into three or more pieces. The operative report should document the segment configuration rather than relying only on a general description of a LeFort I procedure.
Can the bone graft be reported separately?
Bone grafting is part of the service represented by this code. Do not separately report the same grafting work; assess any distinct graft-harvesting work under applicable coding instructions.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
Can modifier 50 or an assistant surgeon be reported?
Modifier 50 is inappropriate for this code. Assistant-at-surgery payment may be made, while co-surgeons and team surgery are not permitted.
How are multiple procedures in the same session paid?
The highest-valued procedure is paid in full, and other procedures in the same session are subject to the standard 50% multiple procedure reduction.
Where these rates come from
