CPT® Code 96920

Excimer laser treatment, specifically identified by CPT® Code 96920, is a targeted therapy designed for the management of mild to moderate plaque psoriasis. This procedure utilizes the XTRAC laser, which emits high-intensity ultraviolet B (UVB) light at a specific wavelength. The laser is directed precisely at the psoriatic plaques, allowing for effective treatment while minimizing exposure to surrounding healthy skin. The treatment is particularly advantageous as it can achieve results comparable to traditional light therapy but typically requires fewer sessions. The focused nature of the laser enables it to penetrate deeper into the affected skin, making it especially useful for challenging areas such as the scalp and the soles of the feet. Prior to the procedure, the dermatologist conducts a thorough examination of the treatment site, assessing the lesions for signs of redness, erythema, blistering, or pain. During the application, the laser wand is aimed directly at the psoriasis patches for a brief duration, with continuous monitoring of the skin's response to ensure optimal treatment outcomes. For billing purposes, CPT® Code 96920 is applicable when the total area treated is less than 250 square centimeters, while codes 96921 and 96922 are designated for larger treatment areas.
