CPT® Code 21196

The procedure described by CPT® Code 21196 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 deformities, improve occlusion, or address trauma-related injuries to the mandible. During the surgery, the physician makes an incision over the mandibular ramus, which is the vertical part of the mandible. The use of specialized instruments such as saws, drills, and osteotomes allows the surgeon to carefully separate the mandible at the predetermined site. Once the mandible is split, it can be repositioned forward to achieve the desired alignment and functional outcome. The fixation of the mandible in its new position is crucial for the success of the procedure; in this case, internal rigid fixation devices are utilized to maintain stability and support during the healing process. After the reconstruction is complete, the incisions are meticulously closed to promote optimal recovery and minimize scarring.
