CPT® Code 21465

The procedure described by CPT® Code 21465 refers to the open treatment of a mandibular condylar fracture, which is a type of fracture occurring in the condyle of the mandible, the bone that forms the lower jaw. This procedure is typically performed by an oral and maxillofacial surgeon or a physician specializing in head and neck surgery. The approach involves making an incision near or through the ear, which allows the surgeon to gain direct access to the fractured area. In some cases, an intraoral incision may be utilized to reach the fracture site more effectively. Once access is achieved, the surgeon carefully dissects the surrounding soft tissue to expose the temporomandibular joint (TMJ) and the fractured condyle. The primary goal of the procedure is to reduce the fracture, meaning the surgeon will reposition the fractured bone fragments back into their correct anatomical alignment. This is crucial for restoring function and preventing complications such as malocclusion or chronic pain. After the fracture is reduced, the condyle is secured in place using various fixation methods, which may include screws, wires, or plates. In certain situations, the fracture may be stable enough that internal fixation is not required. Following the completion of the procedure, all incisions are meticulously closed to promote healing. Additionally, the surgeon may opt to use intermaxillary fixation, a technique that temporarily immobilizes the jaw, if deemed necessary for optimal recovery.
