2025 CPT code 21127
Augmentation of the mandibular body or angle using a bone graft, either onlay or interpositional, including obtaining the autograft.
Modifiers may be applicable to this code to indicate specific circumstances of the procedure, such as increased procedural services (22) or the involvement of multiple surgeons (62).
Medical necessity must be established for this procedure. It is typically covered by insurance when performed to correct functional impairments related to congenital defects, trauma, or disease. Cosmetic augmentations are generally not covered.
The surgeon performs the procedure under anesthesia, making an incision to harvest the bone graft and another incision to access the jawbone. The graft is placed and secured with screws. Additional grafting materials may be used, and the incision is closed with sutures.
In simple words: This procedure increases the size of the lower jaw using a bone graft taken from elsewhere in the patient's body. The graft can be applied on top of the jawbone or within the bone tissue.
This code describes a surgical procedure to augment the size or change the shape of the lower jaw (mandible). The procedure involves using a bone graft, which can be placed on top of the existing bone (onlay) or inserted between layers of bone tissue (interpositional). The bone graft is typically harvested from another site in the patient's body (autograft). The code includes obtaining the autograft.
Example 1: A patient with a receding chin undergoes mandibular augmentation to improve facial harmony., A patient with congenital jaw deformities has surgery to reconstruct the jaw using a bone graft., A patient requires jaw augmentation to support dental implants.
Documentation should include operative reports detailing the surgical technique (onlay or interpositional), the location and amount of bone grafted, the site of autograft harvest, and any complications. Preoperative imaging and medical necessity justification should also be documented.
