Ultraviolet (UV) light treatment of skin disorders in the Dermatologist’s office or at home are covered by this plan. A number of skin conditions are responsive to UV light therapy.  Psoriasis is one of the more common skin disorders that may benefit from UV light therapy.   Topical treatments (creams and ointments) are the first step for treating most types of psoriasis.  While these are convenient and often effective, sometimes other interventions (such as UV light) are needed.  Narrow band UV treatment (using UV B wavelengths of 311-313 nanometers) is readily available and much safer than using a tanning bed which is not medically regulated. UV B light treatment at home is a safe, convenient and effective alternative that should be tried (unless there are specific contraindications) prior to initiating chronic immune suppressing medicines for conditions like psoriasis. Prior authorization is not required for home UV B therapy if for psoriasis.  Home UV B therapy still requires prior authorization for any condition other than psoriasis.

For persons with psoriasis, treatment should not be administered for more than 30 days unless there is improvement.
