CPT® Code 21235

The procedure described by CPT® Code 21235 involves the harvesting of autogenous ear cartilage for use in reconstructive surgery on the nose or ear. This type of graft utilizes the patient's own cartilage, specifically from the auricular or conchal regions of the ear, which minimizes the risk of rejection and complications associated with foreign graft materials. The process begins with making an incision either behind the ear (postauricular incision) or on the front of the ear, allowing access to the cartilage beneath the skin. Once the incision is made, the perichondrium, which is the connective tissue surrounding the cartilage, is carefully incised to expose the cartilage itself. The surgeon then excises a piece of cartilage, ensuring it is of adequate size and shape for the intended reconstructive purpose. After harvesting, the cartilage graft is meticulously shaped using a scalpel to fit the specific defect in the nose or ear. Finally, the graft is placed into the prepared site and secured in position with sutures, completing the procedure. This technique is essential for correcting deformities or reconstructing areas affected by trauma, congenital defects, or surgical excisions, thereby restoring both function and aesthetic appearance.
