A 45-yeаr-оld mаle with а previоus biоpsy positive for malignant melanoma presents for definitive excision of the lesion. After induction of general anesthesia, the patient is placed supine on the OR table, the left knee prepped and draped in the usual sterile fashion. IV antibiotics are given as the patient had previous MRSA infection. The previous excisional biopsy site on the left knee measured approximately 4 cm and was widely ellipsed with a 1.5 cm margin. The excision was taken down to the underlying patellar fascia. Hemostasis was achieved via electrocautery. The resulting defect was 11cm x 5cm. Wide advancement flaps were created inferiorly and superiorly using electrocautery. This allowed skin edges to come together without tension. The wound was closed using interrupted 2-0 Monocryl and 2 retention sutures were placed using #1 Prolene. Skin was closed with a stapler. What CPT® code(s) is/are reported?
