CPT® Code 11602

The CPT® Code 11602 refers to the excision of a malignant lesion located on the trunk, arms, or legs, specifically when the excised diameter of the lesion measures between 1.1 to 2.0 cm. This procedure involves the surgical removal of the malignant tissue along with a margin of healthy tissue to ensure complete excision of the cancerous cells. Common types of malignant lesions that may be excised using this code include basal cell carcinoma, squamous cell carcinoma, verrucous carcinoma, and melanoma. The process begins with the cleansing of the area and the administration of a local anesthetic to minimize discomfort during the procedure. A careful identification of a healthy tissue margin is crucial, followed by a full-thickness incision made through the dermis surrounding the lesion. The entire lesion is then excised, and if necessary, a frozen section may be performed to verify that the margins are clear of malignant cells. Should any malignant tissue be detected at the margins, additional excision is performed until all margins are confirmed clean. The excised lesion is subsequently sent to a laboratory for histologic evaluation, which is also reportable separately. To manage any bleeding during the procedure, electrocautery or chemical cautery techniques are employed. Finally, the surgical wound may be closed using a simple single-layer suture technique, although 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.
