CPT® Code 17004

Destruction (eg, laser surgery, electrosurgery, cryosurgery, chemosurgery, surgical curettement), premalignant lesions (eg, actinic keratoses), 15 or more lesions

The CPT® Code 17004 refers to the destruction of premalignant lesions, specifically when 15 or more lesions are treated. Premalignant lesions, such as actinic keratoses (AK), are abnormal growths that can develop on sun-exposed skin and are considered precursors to skin cancer. Actinic keratoses typically manifest as rough, scaly patches and are confined to the epidermis, the outermost layer of skin. The procedure involves a thorough examination of the lesions to determine the most suitable method of destruction. Various techniques can be employed, including laser surgery, electrosurgery, cryosurgery, chemosurgery, and surgical curettage. Local anesthesia may be administered to ensure patient comfort during the procedure. Among these methods, cryosurgery, which utilizes liquid nitrogen to freeze the lesions, is the most frequently used technique. Additionally, surgical curettage followed by electrosurgery is another common approach. For cases involving multiple lesions, treatment may also involve chemical or pharmacologic agents or laser resurfacing with a carbon dioxide laser. It is important to note that for billing purposes, CPT® Code 17000 is used for the destruction of the first lesion, while CPT® Code 17003 is applicable for each lesion from the second through the fourteenth. CPT® Code 17004 is specifically designated for the treatment of 15 or more lesions.
