Official Description

Augmentation, mandibular body or angle; with bone graft, onlay or interpositional (includes obtaining autograft)

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 21127 involves the augmentation of the mandibular body or angle, which is a surgical intervention aimed at enhancing the structure and contour of the lower jaw. This augmentation can be achieved through the use of a bone graft, which is a piece of bone taken from another part of the patient's body, or through the application of prosthetic material. The procedure is comprehensive, as it includes the process of obtaining the autograft, which is the harvesting of the patient's own bone. The physician typically performs this surgery through both intraoral and extraoral incisions, allowing for effective access to the mandible. The harvested bone graft is then carefully placed into the targeted area of the mandible and secured using wires or screws to ensure stability. Following the placement of the graft, all incisions are meticulously closed to promote healing and minimize scarring. This procedure is essential for patients requiring structural support in the mandible due to various conditions, including congenital defects, trauma, or previous surgical interventions.
