CPT® Code 96922

Excimer laser treatment, specifically identified by CPT® Code 96922, is a specialized procedure aimed at managing mild to moderate plaque psoriasis. This treatment utilizes the XTRAC laser therapy, which delivers concentrated bursts of high-intensity ultraviolet B (UVB) light at a precise wavelength. The laser is directed specifically at the psoriatic plaques on the skin, ensuring that the surrounding healthy skin remains untouched. This targeted approach allows for effective treatment of the lesions while minimizing damage to adjacent tissues. The procedure is particularly advantageous as it can achieve results comparable to traditional light therapy but typically requires fewer treatment sessions. The intense nature of the laser light penetrates deeper into the affected skin, making it more effective for challenging areas such as the scalp and the soles of the feet. Prior to treatment, the dermatologist conducts a thorough examination of the treatment site, assessing the lesions for signs of redness, erythema, blistering, or pain. The laser wand is then aimed directly at the patches of psoriasis for a brief duration, with the dermatologist continuously monitoring the skin's response throughout the procedure. For coding purposes, it is important to note that different CPT® codes are designated based on the total area treated: 96920 for areas less than 250 square centimeters, 96921 for areas between 250 and 500 square centimeters, and 96922 for areas exceeding 500 square centimeters.
