CPT® Code 11424

Excision, benign lesion including margins, except skin tag (unless listed elsewhere), scalp, neck, hands, feet, genitalia; excised diameter 3.1 to 4.0 cm

The CPT® Code 11424 refers to the excision of a benign lesion, which is a non-cancerous growth, from specific areas of the body including the scalp, neck, hands, feet, or genitalia. This procedure is performed on lesions that are not classified as skin tags, unless they are specified in other coding categories. The excised lesion has a diameter ranging from 3.1 to 4.0 centimeters. Common types of benign lesions that may be excised using this code include lipomas, which are fatty tumors; dermatofibromas, which are fibrous skin growths; pyogenic granulomas, which are small, red, and raised lesions; epidermoid cysts, which are small lumps beneath the skin; and benign nevi, commonly known as moles. During the procedure, the area surrounding the lesion is thoroughly cleansed, and a local anesthetic is administered to minimize discomfort. A careful identification of a narrow margin of healthy tissue surrounding the lesion is crucial, as this ensures complete removal of the lesion along with a buffer of normal tissue to reduce the risk of recurrence. A full-thickness incision is made through the dermis, encircling the lesion, and the entire growth is excised. The excised tissue is then sent to a laboratory for histologic evaluation, which is a separate reportable service. To manage any bleeding that may occur during the procedure, electrocautery or chemical cautery techniques are employed. After the excision, the surgical wound may be closed using a simple single-layer suture technique; however, more complex closure methods such as intermediate (layer) closure, complex repair, skin grafts, or pedicle flaps may also be utilized depending on the specific circumstances of the excision and the wound's characteristics.
