Photodynamic therapy by external application of light to destroy premalignant lesions of the skin and adjacent mucosa with application and illumination/activation of photosensitive drug(s), per day

Photodynamic therapy (PDT) is a medical procedure that employs the use of photosensitive or photoreactive chemicals in conjunction with light to effectively target and destroy premalignant lesions located on the skin and adjacent mucosa. This therapy involves the topical application of these photosensitive agents to all identified lesions within a designated anatomical area, which may include regions such as the face or scalp. Prior to the application of the photosensitive drugs, the lesions may require preparation, which can involve the removal of any overlying crust or scale to enhance the effectiveness of the treatment. Following the application of the photosensitive chemicals, the lesions are subjected to irradiation using light of a specific wavelength. This light serves to activate the photoreactive chemicals, leading to a photochemical reaction that results in the destruction of the targeted lesions. The CPT® Code 96567 is utilized to report this procedure, which is performed once per day, and it is important to note that this code is applicable when the treatment is conducted without the direct involvement of a physician or other qualified healthcare professional in the procedure.
