CPT® Code 21195

The procedure described by CPT® Code 21195 involves the surgical reconstruction of the mandibular rami and/or body through a technique known as a sagittal split. This procedure is typically performed to correct various dental and skeletal issues related to the jaw. The term "mandibular rami" refers to the two vertical portions of the mandible, while the "body" refers to the horizontal portion that forms the chin. The sagittal split technique entails making an incision over the mandibular ramus, which allows the surgeon to access the bone directly. Using specialized instruments such as saws, drills, and osteotomes, the surgeon carefully separates the mandible along a predetermined line. Once the mandible is split, it can be repositioned forward to achieve the desired alignment and occlusion. This procedure is coded as 21195 when the mandible is stabilized using wires, as opposed to an internal rigid fixation device, which would be coded under 21196. After the surgical manipulation, the incisions made during the procedure are closed to promote healing and restore the integrity of the oral cavity.
