CPT® Code 11310

Shaving of epidermal or dermal lesion, single lesion, face, ears, eyelids, nose, lips, mucous membrane; lesion diameter 0.5 cm or less

The CPT® Code 11310 refers to the procedure of shaving an epidermal or dermal lesion that is singularly located on specific areas of the body, including the face, ears, eyelids, nose, lips, or mucous membranes. This procedure is typically indicated for lesions that have a diameter of 0.5 cm or less. Common types of lesions that may be treated with this method include pedunculated lesions, seborrheic keratoses, fibrous papules, and other similar growths that possess a minimal dermal component. The shaving technique involves removing the lesion by making incisions that do not penetrate deeper than the middle dermis, thereby preserving the integrity of the subcutaneous layer beneath. Prior to the procedure, the area is thoroughly cleansed, and a local anesthetic is administered to ensure patient comfort. The actual removal of the lesion is performed using a blade, which may involve either a transverse incision or repetitive horizontal slicing in a consistent direction. After the lesion is excised, the physician inspects the surrounding tissue to confirm complete removal of the lesion. The edges of the resulting wound are smoothed, and any bleeding is controlled through the use of electrocautery or chemical cautery. Following the procedure, the excised lesion is sent to a laboratory for histologic evaluation, which is separately reportable. It is important to note that different CPT® codes are designated for lesions of varying sizes, with 11310 specifically applicable for those measuring 0.5 cm or less.
