What 21209 covers
A surgeon reduces a prominent facial bone by removing or reshaping bone to change its contour. Plastic surgeons and oral and maxillofacial surgeons may perform this as facial skeletal contouring when the operative goal is to decrease bony prominence, rather than reconstruct a jaw or add volume with graft or implant material. The operative report should identify the bone treated and describe the reduction performed.
Report the service for the documented reduction, not for facial bone augmentation or bone grafting. Documentation should establish the treated site, the bony work performed, and the reason for contour reduction. Medicare assigns a 90-day global period: the day-before preoperative visit and 90 days of related postoperative care are included. 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 multiple-procedure reduction. Modifier 50 is inappropriate for this code. An assistant at surgery may be paid; co-surgeons and team surgery are not permitted.

How to choose
- 21208Bone augmentation
- 21209 reduces facial bone prominence; 21208 addresses facial bone augmentation. Select based on whether the operation removes or reshapes bone to reduce prominence or adds volume.
- 21270Cheek augmentation
- 21270 is for cheekbone augmentation. Use 21209 when the documented procedure reduces facial bone prominence rather than augmenting the cheekbone.
- 21206Maxillary osteotomy
- 21206 describes reconstruction of the upper jaw. It is distinct from reduction performed to contour a facial bone without reconstructing the maxilla.
21209 billing questions
How is reduction distinguished from facial bone augmentation?
Use 21209 when the operative goal is to reduce bony prominence. Code 21208 describes augmentation of facial bones, an opposite contouring goal.
Should modifier 50 be reported for reduction on both sides?
No. CMS identifies bilateral adjustment as inappropriate for this code; modifier 50 should not be used.
What documentation supports reporting 21209?
The operative report should identify the facial bone treated and describe the bone removal or reshaping that reduced its prominence.
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 another surgeon be reported?
An assistant at surgery may be paid. Co-surgeons and team surgery are not permitted for this code under the CMS rules provided.
