CPT® Code 21421

Closed treatment of palatal or maxillary fracture (LeFort I type), with interdental wire fixation or fixation of denture or splint

The CPT® Code 21421 refers to the closed treatment of a palatal or maxillary fracture classified as LeFort I type. This procedure is characterized by the absence of incisions, meaning that it is performed without any surgical cuts to the tissue. Instead, the physician utilizes interdental wire fixation, which involves securing the dental arches within the patient's mouth to stabilize the fracture. This method is crucial for maintaining the proper alignment of the maxilla during the healing process. Additionally, in some cases, the physician may opt to use dentures or splints as alternative means of fixation to provide the necessary support for the fractured area. The goal of this procedure is to ensure that the maxillary structure heals correctly, thereby restoring function and aesthetics to the patient's oral cavity.
