CPT® Code 17266

Destruction, malignant lesion (eg, laser surgery, electrosurgery, cryosurgery, chemosurgery, surgical curettement), trunk, arms or legs; lesion diameter over 4.0 cm

The CPT® Code 17266 refers to the destruction of malignant lesions located on the trunk, arms, or legs, specifically when the diameter of the lesion exceeds 4.0 cm. Malignant lesions are abnormal growths that can invade surrounding tissues and may spread to other parts of the body. Common types of malignant lesions include squamous cell carcinoma and verrucous carcinoma. While excision is a standard treatment for many malignant lesions, certain cases, particularly those that have not penetrated deeper layers of the dermis, may be treated using various destruction techniques. These techniques aim to eliminate the lesion while minimizing damage to surrounding healthy tissue. The procedure typically begins with an examination of the lesion to determine the most suitable method of destruction. Local anesthesia may be administered to ensure patient comfort during the procedure. Various destruction methods include cryosurgery, which involves freezing the lesion with liquid nitrogen; surgical curettage, which is often followed by electrosurgery; chemosurgery, which utilizes chemical agents to destroy the lesion; and laser destruction, particularly with carbon dioxide lasers. This code is specifically designated for larger lesions, as indicated by the size requirement, and is part of a series of codes that categorize malignant lesion destruction based on their diameter.
