CPT® Code 21422

The CPT® Code 21422 refers to the open treatment of a palatal or maxillary fracture classified as LeFort I type. This procedure is performed to address fractures that occur in the upper jaw, specifically in the maxilla, which is the bone that forms the upper jaw and supports the teeth. The term "LeFort I" describes a specific type of fracture that involves a horizontal fracture line above the teeth, which can lead to significant displacement of the maxillary bone. During the procedure, the physician makes incisions in the buccal vestibule, which is the area of the oral cavity adjacent to the gums. This approach allows for direct access to the fractured bone. Once the fracture is exposed, the physician carefully repositions the bone segments to their correct anatomical alignment. To ensure stability and proper healing, the repositioned bone segments are secured using various fixation devices such as screws, plates, or pins. After the stabilization is complete, the incisions made during the procedure are closed. In some cases, additional methods such as intermaxillary or interdental fixation may be employed to provide further support and stabilization to the fracture during the healing process.
