CPT® Code 11621

The CPT® Code 11621 refers to the excision of a malignant lesion located on specific areas of the body, including the scalp, neck, hands, feet, or genitalia. This procedure involves the 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 procedure begins with the cleansing of the affected area, followed by the administration of a local anesthetic to minimize discomfort during the excision. A full-thickness incision is then made through the dermis, carefully encircling the lesion to remove it entirely. To confirm that the excised margins are free of malignant cells, a frozen section may be performed during the procedure. If any malignant tissue is detected at the margins, additional tissue will be excised until clear margins are achieved. The excised lesion is subsequently sent to a laboratory for histologic evaluation, which is also reportable separately. To manage any bleeding that may occur 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.
