About 21120: Chin augmentation genioplasty
Reports surgical chin augmentation using implanted or grafted material when the surgeon increases chin projection without performing a sliding genioplasty.
This procedure increases chin projection or contour by adding material to the chin, such as an implant or graft. It is typically performed by an oral and maxillofacial surgeon, plastic surgeon, or facial plastic surgeon to address a retrusive or under-projected chin. The operative work is augmentation of the chin itself, rather than repositioning a segment of the chin bone through a sliding osteotomy.
Select the code when the operative report supports chin augmentation and identifies the material and technique. Distinguish it from sliding genioplasty codes, which involve osteotomy and repositioning, and from mandibular augmentation directed at a broader jaw area. 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 one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Assistant-at-surgery payment is restricted by statute; co-surgeons are paid only with supporting documentation, and team surgery is not permitted.

21120 billing questions
How is this different from a sliding genioplasty?
This code describes chin augmentation with added material. Sliding genioplasty codes describe cutting and repositioning the chin bone, with the code choice depending on the osteotomy and augmentation performed.
Can this code be reported with a sliding genioplasty?
A sliding genioplasty that also includes augmentation is represented by the specific combined code, 21123. Do not separately report 21120 for the same augmentation work included in that procedure.
What should the operative report document?
Document the chin-specific purpose, the material used, its placement, and the technique. The report should make clear that the work augmented the chin rather than repositioning a bony segment.
Are related postoperative visits included?
Yes. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
How does Medicare handle another procedure performed in the same session?
The highest-valued procedure is paid in full, and other procedures in that session are subject to the standard multiple-procedure reduction.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment is restricted by statute. Co-surgeons are paid only with supporting documentation; team surgery is not permitted.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
