CPT® Code 11312

Shaving of epidermal or dermal lesion, single lesion, face, ears, eyelids, nose, lips, mucous membrane; lesion diameter 1.1 to 2.0 cm

The procedure described by CPT® Code 11312 involves the shaving of a single epidermal or dermal lesion located on the face, ears, eyelids, nose, lips, or mucous membrane. This technique is typically employed for lesions that have a diameter ranging from 1.1 to 2.0 cm. Common types of lesions that may be treated using this method include pedunculated lesions, seborrheic keratoses, fibrous papules, and other similar lesions that possess a minimal dermal component. The shaving technique is designed to remove the lesion while preserving the underlying subcutaneous layer, as the procedure extends only to the middle dermis. Prior to the shaving process, 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 the same direction. After the lesion is excised, the physician inspects the surrounding tissue to confirm complete removal. The edges of the resulting wound are then smoothed, and any bleeding is controlled through the use of electrocautery or chemical cautery. Following the procedure, the shaved specimen is sent to a laboratory for histologic evaluation, which is separately reportable. It is important to note that there are specific CPT® codes for different lesion sizes: 11310 for lesions measuring 0.5 cm or less, 11311 for lesions measuring 0.6-1.0 cm, 11312 for lesions measuring 1.1-2.0 cm, and 11313 for lesions exceeding 2.0 cm in diameter.
