Ultraviolet Modality (CPT code 97028)

Photons in the ultraviolet (UV) spectrum are more energetic than those in the visible or infrared regions. Their interaction with tissue and bacteria can produce nonthermal photochemical reactions, the effects of which provide the rationale for ultraviolet treatment. Ultraviolet light is highly bacteriocidal to motile bacteria, and it increases vascularization at the margins of the wounds.

The application of ultraviolet therapy is considered medically necessary for the patient requiring the application of a drying heat. The specific indications for this therapy are:

– A patient has an open wound. Minimal erythema dosage must be documented.

– Severe psoriasis limiting range of motion.
