• a. a lesion with clinical margins greater than 1.5 cm;
• b. a lesion located in an anatomically sensitive area, in particular but not limited to the periocular, perinasal, perilabial, and periauricular surfaces, or the nose;
• c. a recurrent malignancy that has not responded to prior therapy;
• d. a malignant lesion in a patient with immunodeficiency or genodermatoses predisposing to widespread skin cancers, such as basal cell nevus syndrome;
• e. a histologically aggressive lesion (such as a basal cell carcinoma that is sclerosing, infiltrative, baso-squamous, or micronodular, or a squamous cell carcinoma that is poorly differentiated, or demonstrates peri-neural/lymphatic/vascular involvement) at any anatomic site.
Closure of the resulting defect by undermining and advancement flaps is included in the fees. More complicated closure may be eligible for payment using skin flap and graft codes.
