About 11426: Large benign lesion excision of scalp or extremity site
Reports excision of a benign skin lesion larger than 4 cm, including margins, from the scalp, neck, hands, feet, or genitalia.
This code is for surgical removal of a benign skin lesion with a total excised diameter greater than 4 cm, including the lesion and its margins. Typical cases include a large benign nevus or cyst on the scalp, hand, or foot. A physician or other qualified practitioner performs the excision in an office, clinic, or surgical setting; the specimen may be sent for pathology.
Choose the code by the anatomic group and the excised diameter, which includes the lesion plus the narrowest margins—not by lesion size alone. Document the site, lesion dimensions, margins, total excised diameter, and diagnosis; record the closure type and length if a separately reportable repair is performed. Simple closure is included, while intermediate or complex repair may be reported separately when supported. Related postoperative visits during the 10-day global period are included. When multiple procedures are performed in one session, the highest-valued procedure is paid in full and other procedures are subject to a 50% reduction. Modifier 50 is inappropriate for this descriptor. Assistant-at-surgery payment is barred, and co-surgeon and team-surgery reporting are not permitted.
