What 21125 covers

Mandibular augmentation with a prosthetic implant enlarges or restores jaw contour by placing alloplastic material along a deficient segment of the mandible. It is distinct from bone-graft augmentation and from an osteotomy that repositions native jaw segments. Oral and maxillofacial surgeons and plastic surgeons typically perform the procedure in an operating room for reconstructive or contour-correction needs, using an implant selected for the documented mandibular deficiency.

Report 21125 when the operative service augments the mandible with prosthetic material. The note should identify the treated mandibular area, the indication, the implant and its placement, and the work performed. CMS assigns a 90-day global period, including the day-before preoperative visit and related postoperative care through day 90. For multiple procedures in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment may be made; co-surgeons and team surgery are 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.
