Ultraviolet light therapy (UVB) used in the home is a piece of durable medical equipment that typically contains multiple fluorescent lights that emit high intensity, long-wave ultraviolet light (UVB rays). These boxes may be used for various reasons including treatment of psoriasis, eczema, photodermatoses, pruritis, pityriasis, lichen planus,
UVB light can be categorized as wide-band and narrow-band, which refers to the range of wavelengths included in the UV light source. The wide-band devices deliver full spectrum UVB light. The narrow-band devices deliver a very narrow range of the UV light spectrum, focusing on the specific wavelengths most effective for the treatment of disease. Narrow-band UVB light can be delivered with either a light bulb or with a hand held laser device. UVB treatment is typically offered using a light “booth” or “light box” several times a week for as long as the condition persists, which may be for the lifetime of the individual. In most cases an individual must go to a doctor’s office or other facility for treatments. However, UVB treatment is available for home use under certain circumstances and under strict physician supervision.
Ultraviolet light therapy is considered reasonable and necessary when used for the treatment of any of the following skin conditions and meet the coverage criteria listed below:
• Atopic dermatitis/eczema, when topical treatment alone has failed; or • Pityriasis lichenoides; or • Pruritus of hepatic disease; or • Pruritus of renal failure; or • Cutaneous T-Cell Lymphma/Mycosis Fungoides (CTCL/MF); or • Psoriasis, when topical treatment alone has failed.
