CPT® Code 11311

Shaving of epidermal or dermal lesion, single lesion, face, ears, eyelids, nose, lips, mucous membrane; lesion diameter 0.6 to 1.0 cm

The CPT® Code 11311 refers to the procedure of shaving a single epidermal or dermal lesion located on the face, ears, eyelids, nose, lips, or mucous membrane, specifically when the lesion has a diameter ranging from 0.6 to 1.0 cm. This procedure is typically performed to remove various types of lesions, including pedunculated lesions, seborrheic keratoses, fibrous papules, and other similar growths that possess a minimal dermal component. The shaving technique involves 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 executed using a surgical blade, which may involve transverse incisions 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 then smoothed, and any bleeding is controlled through electrocautery or chemical cautery methods. 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: CPT® Code 11310 is used for lesions measuring 0.5 cm or less, CPT® Code 11311 for those measuring 0.6 to 1.0 cm, CPT® Code 11312 for lesions between 1.1 to 2.0 cm, and CPT® Code 11313 for lesions exceeding 2.0 cm in diameter.
