CPT® Code 21138

Forehead reduction surgery, specifically described by CPT® Code 21138, is a surgical procedure aimed at reducing and reshaping a prominent or asymmetrical frontal bone in the forehead region. This procedure is particularly relevant for individuals who may have an overly prominent forehead or asymmetrical features that can affect their appearance and self-esteem. The surgery begins with an incision made at the junction of the forehead and the hairline, allowing access to the underlying structures. The skin and soft tissues of the forehead are carefully undermined to the level of the brows, exposing the frontal bone. Unlike the procedure described in CPT® Code 21137, which involves contouring alone, CPT® Code 21138 incorporates both contouring and the application of prosthetic materials or bone grafts to achieve the desired aesthetic outcome. This dual approach not only reduces bony prominences but also addresses any asymmetry present in the frontal bone. The procedure may involve the use of bone cement or harvested bone grafts to fill in depressions and sculpt the frontal bone to restore symmetry. The use of autografts, typically harvested from the iliac crest, is also a critical component of this procedure, ensuring that the material used for reconstruction is biocompatible and effective in achieving the desired contour. Overall, this surgical intervention is designed to enhance the facial profile by creating a more balanced and aesthetically pleasing forehead contour.
