Prior authorization: Dermatologist/qualified prescriber and HCPCS codes

Prior authorization is required for home narrowband UVB devices; the device must be prescribed by a dermatologist or other qualified treating clinician experienced in ultraviolet phototherapy and the request should use the commonly submitted HCPCS codes for home phototherapy devices (E0691–E0694). Prior auth requests should demonstrate the device meets the policy’s medical necessity criteria.

• Prescriber must be a dermatologist or qualified treating clinician experienced in ultraviolet phototherapy.
• Expected HCPCS codes for requests: E0691, E0692, E0693, E0694.
• Request must document that the device and member meet the policy’s medical necessity criteria.

Conventional therapy requirement: Prior adequate trial needed

Home phototherapy is covered only after an adequate trial of condition-appropriate conventional therapy has been attempted unless the clinician documents contraindication, intolerance, or that conventional therapy is clinically inappropriate; alternative covered services include dermatology evaluation and standard topical, systemic, biologic, or other guideline-supported treatments.

• Use before an adequate trial of condition-appropriate conventional therapy is not medically necessary unless contraindicated, not tolerated, or clinically inappropriate.
• Document prior use of guideline-supported topical, systemic, biologic, or other treatments when applicable.

Required documentation: Written home phototherapy plan

The treating clinician must provide a written home phototherapy plan that identifies the diagnosis, baseline severity or photographs, treatment area, device type/configuration, starting dose, dose escalation, treatment frequency, maximum exposure limits, missed-treatment and adverse-event instructions, safety precautions, and a follow-up schedule.

• Include baseline severity or photographs and intended treatment area.
• Specify device type/configuration and features (timer, dose controls, lockout/restricted-use, exposure tracking, protective eyewear).
• Document starting dose, dose escalation plan, treatment frequency, maximum exposure limits, missed-treatment instructions, adverse-event instructions, and follow-up schedule.

Common denial triggers: Noncovered therapies and missing plan/follow-up

Common denial triggers include requests for home UVA or PUVA photochemotherapy, use for tanning/wellness/cosmetic purposes, requests that duplicate or upgrade functional existing equipment, and requests submitted without a clinician’s written treatment plan and scheduled follow-up.

• Requests for home UVA therapy or home psoralen UVA (PUVA) photochemotherapy are not medically necessary.
• Use for tanning, wellness, or cosmetic purposes will be denied.
• Duplicate or upgraded equipment when an existing device is functional is not covered.
• Requests without a clinician’s written treatment plan and scheduled follow-up may be denied.
