What 21120 covers

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.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

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 indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
