CPT® Code 21194

The procedure described by CPT® Code 21194 involves the reconstruction of the mandibular rami, which are the vertical parts of the lower jawbone. This reconstruction is achieved through various types of osteotomies, specifically horizontal, vertical, C, or L-shaped cuts in the bone. The primary goal of this surgical intervention is to correct deformities of the mandible, which may arise from congenital issues, trauma, or other pathological conditions. The procedure is performed under general anesthesia to ensure the patient is completely unconscious and free from pain during the operation. The surgeon makes incisions, which may include an intraoral approach, to access the mandible effectively. Once the mandibular rami are exposed, specialized surgical instruments such as osteotomes, saws, and burs are utilized to create precise cuts in the bone. This allows the surgeon to separate the mandible into distinct parts, which can then be repositioned to achieve the desired anatomical alignment. To secure the newly formed structure, the surgeon employs fixation devices such as plates, screws, and wires. In cases where additional support is required, a bone graft may be harvested from the patient's own body, typically from the hip, rib, or skull, and placed at specific sites within the surgical area to promote healing and stability. The use of an antibiotic solution is standard practice to minimize the risk of infection, and the incisions are subsequently closed to complete the procedure. It is important to note that intermaxillary fixation may be necessary to maintain the position of the mandible during the initial healing phase. This code is specifically used when bone grafts are involved; if no graft is required, a different code (CPT® Code 21193) should be utilized.
