CPT® Code 21125

The procedure described by CPT® Code 21125 involves the augmentation of the mandibular body or angle using prosthetic material. This surgical intervention is typically performed to enhance the contour of the mandible, which may be necessary due to congenital deformities, trauma, or other conditions that affect the jaw's structure. During the procedure, the physician makes an incision either extraorally or at the angle of the mandible, allowing access to the underlying bone. A synthetic prosthesis is then carefully inserted onto the mandible. This prosthetic material is designed to provide support and improve the aesthetic appearance of the jawline. The prosthesis is secured in place using wires or screws to ensure stability and proper integration with the surrounding bone. This procedure is distinct from similar interventions, such as those involving bone grafts, which utilize the patient's own bone material for augmentation. The use of prosthetic material in this context allows for a more straightforward approach to achieving the desired contour of the mandible.
