Summary
BCBS Mississippi updated their Light Therapy for Psoriasis policy (L.2.01.435), establishing coverage criteria for PUVA therapy and targeted phototherapy based on disease severity and treatment failure. The policy specifies when these treatments are medically necessary versus investigational.
Action Required
Immediately: Billing team must verify psoriasis patients meet coverage criteria before submitting claims for light therapy treatments. For PUVA therapy, confirm severe disabling psoriasis unresponsive to conservative treatment. For targeted phototherapy, verify moderate-to-severe localized psoriasis <20% body area or mild-to-moderate disease unresponsive to conservative treatment. Document disease severity and prior treatment failures in medical records to support medical necessity.
