CPT® Code 11401

Excision, benign lesion including margins, except skin tag (unless listed elsewhere), trunk, arms or legs; excised diameter 0.6 to 1.0 cm

The procedure described by CPT® Code 11401 involves the excision of a benign lesion from the trunk, arms, or legs, specifically when the excised diameter of the lesion measures between 0.6 to 1.0 cm. A benign lesion is defined as a non-cancerous growth that does not pose a threat to health, and it can include various types of skin abnormalities such as lipomas, dermatofibromas, pyogenic granulomas, epidermoid cysts, and benign nevi. During the procedure, the area surrounding the lesion is thoroughly cleansed, and a local anesthetic is administered to ensure patient comfort. The surgeon identifies a narrow margin of healthy tissue around the lesion to ensure complete removal and minimize the risk of recurrence. A full-thickness incision is made through the dermis, encircling the lesion, which is then excised in its entirety. The excised tissue is sent to a laboratory for histologic evaluation, which is separately reportable. To manage any bleeding that may occur during the procedure, electrocautery or chemical cautery techniques are employed. After the lesion is removed, the surgical wound may be closed using a simple single-layer suture technique. However, if necessary, more complex closure methods such as intermediate (layer) closure, complex repair, skin grafts, or pedicle flaps may be utilized. This procedure is essential for the removal of benign lesions that may cause discomfort or cosmetic concerns for the patient.
