About 21206: Segmental maxillary osteotomy
Reports a segmental osteotomy of the maxilla to reposition upper-jaw segments, commonly to correct dentofacial deformity and improve occlusion.
This service involves surgically dividing the maxilla into segments and repositioning them to correct upper-jaw alignment, dental-arch relationships, or occlusion. Oral and maxillofacial surgeons and other surgeons with appropriate facial-surgery expertise perform it, typically in an operating room. It is distinct from simply reshaping facial bone or adding bone or an implant to the maxilla.
Report 21206 when the operative work is a segmental maxillary osteotomy; the operative note should support the indication, the portions of the maxilla treated, and the osteotomy and repositioning performed. CMS assigns a 90-day global period, including 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 payment is not permitted. Modifier 50 is inappropriate for this code.

21206 billing questions
How is 21206 different from 21208?
21206 represents a segmental osteotomy that repositions portions of the maxilla. 21208 is for facial-bone augmentation, such as adding bone or implant material, rather than dividing and repositioning the upper jaw.
When should 21209 be considered instead?
Use 21209 for reduction or contouring of facial bone. Choose 21206 when the documented service is a segmental maxillary osteotomy with repositioning, not simply bone reduction.
Does 21206 include a separate bone graft?
The code describes the segmental maxillary osteotomy, not bone grafting as a separate service. Code 21210 describes grafting to nasal, maxillary, or malar areas; separate reporting depends on the work documented and applicable coding edits.
Can modifier 50 be reported?
No. CMS identifies modifier 50 as inappropriate for this code's descriptor or anatomy.
What postoperative care is included in the global period?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
