What 11640 covers

This code covers removal of a malignant skin lesion from the face, ear, eyelid, nose, or lip, with the margins needed for excision. Dermatologists, plastic surgeons, and other qualified physicians commonly perform the procedure in an office or outpatient surgical setting. The size category is based on the excised diameter, including the lesion and margins—not the lesion alone. The code includes simple closure; a separately performed intermediate or complex repair may be reported when supported by the service and documentation.

Choose this code when the anatomic site is one of the specified facial sites and the excised diameter is 0.5 cm or less. Document the lesion’s location and size, the margins taken, and the resulting excised diameter; retain pathology findings supporting the malignant diagnosis. CMS assigns a 10-day global period, so related postoperative visits during that period are included. For multiple procedures in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Assistant-at-surgery payment is statutorily restricted, and co-surgeons and team surgery are not permitted.
