CPT® Code 21244

The procedure described by CPT® Code 21244 involves the reconstruction of the mandible, which is the lower jawbone, using a specialized technique known as an extraoral approach. This approach entails accessing the mandible from outside the mouth, allowing the physician to effectively dissect the surrounding tissue away from the bone. The primary purpose of this reconstruction is to prepare the jaw for the placement of dentures, which are artificial replacements for missing teeth. During the procedure, a transosteal bone plate, such as a mandibular staple bone plate, is utilized. This plate is designed to provide structural support and stability to the mandible. The process includes drilling holes through the mandible and into the oral cavity, where posts connected to the bone plate are inserted. These posts serve as anchors for the bone plate, which is then secured in place using an external fixation device. Finally, all incisions made during the procedure are meticulously closed to promote healing and minimize complications.
