The procedure described by CPT® Code 11641 involves the excision of a malignant lesion located on the face, ears, eyelids, nose, lips, or mucous membranes, with an excised diameter ranging from 0.6 to 1.0 cm. This procedure is typically performed to remove cancerous growths, which may include types such as basal cell carcinoma, squamous cell carcinoma, verrucous carcinoma, and melanoma. The excision is conducted with the intent to not only remove the malignant tissue but also to include a margin of healthy tissue surrounding the lesion to ensure complete removal and minimize the risk of recurrence. Prior to the excision, the area is thoroughly cleansed, and a local anesthetic is administered to ensure patient comfort during the procedure. A full-thickness incision is made through the dermis, carefully encircling the lesion to excise it completely. In some cases, a frozen section may be performed during the excision to verify that the margins are clear of malignant cells. If any malignant tissue is detected at the margins, further excision is carried out until all margins are confirmed to be free of cancerous cells. The excised lesion is then sent for histologic evaluation to assess the nature of the tissue. 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, 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 and the size of the wound.

The procedure associated with CPT® Code 11641 is indicated for the excision of malignant lesions located on the face, ears, eyelids, nose, lips, or mucous membranes. The specific conditions or symptoms that may warrant this procedure include:
The procedure for excising a malignant lesion as described by CPT® Code 11641 involves several critical steps:
After the excision procedure, patients are typically monitored for any immediate complications. Post-procedure care may include instructions on wound care to promote healing and prevent infection. Patients may be advised to keep the area clean and dry, and to follow up with their healthcare provider for suture removal or further evaluation of the excised tissue. Recovery time can vary based on the size and location of the excised lesion, as well as the method of closure used. It is important for patients to report any signs of infection, such as increased redness, swelling, or discharge from the wound, to their healthcare provider promptly.
