Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 21122 covers

This operation reshapes or repositions the chin by making at least two cuts in the mandibular symphysis and moving the resulting bone segments. Oral and maxillofacial, plastic, or craniofacial surgeons may perform it to address chin shape or position, commonly in an operating room in a hospital or ambulatory surgery center. The defining feature is the multiple-cut sliding technique, rather than a single osteotomy or augmentation with an implant or graft.

Choose 21122 when the operative report supports two or more osteotomies for the sliding genioplasty. Document the cuts, movement and reshaping of the chin segments, and any grafting performed; a single osteotomy is reported with 21121, while interpositional bone graft augmentation is distinguished by 21123. The code has a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard reduction. Report this midline service without modifier 50. An assistant at surgery may be paid; co-surgeons and team surgery are not permitted.
