Defines medical necessity and coverage criteria for home narrowband UVB phototherapy devices for photoresponsive skin conditions and excludes home UVA/PUVA and non-therapeutic uses; applies to AmeriHealth Caritas members and their treating clinicians.
No material clinical or coverage changes in this revision.
Coverage Criteria
Medically necessary — home narrowband UVB
Covered when ALL of the following are met:
Not medically necessary / Excluded uses
The following are not covered:
The policy excludes several uses of home ultraviolet light therapy equipment that are considered not medically necessary. Specifically, home ultraviolet A (UVA) therapy and home psoralen UVA (PUVA) photochemotherapy are not covered. Also excluded are use for tanning, wellness, or cosmetic purposes; initiation of home phototherapy before an adequate trial of condition-appropriate conventional therapy unless contraindicated/not tolerated/clinically inappropriate; use without a clinician's written treatment plan and scheduled follow-up; requests for duplicate or upgraded equipment when an existing device is functional; and use when contraindications make home UV exposure inappropriate. These operational limits reflect the policy’s stance that only defined, clinically justified home NB-UVB use with appropriate safeguards is eligible for coverage.
The policy states that home UVA devices and home psoralen UVA (PUVA) photochemotherapy devices are investigational/not clinically proven for home use and therefore are not medically necessary under this policy. Requests for these devices should be denied unless new evidence or policy revisions establish clinical benefit and appropriate safety in the home setting.

Provider Actions & Authorization
Device prior authorization required
Home narrowband UVB devices (commonly billed E0691–E0694) require a prescription from a dermatologist or other qualified treating clinician and documentation that the coverage criteria are met prior to authorization.
- Device is prescribed by a dermatologist or other qualified treating clinician experienced in ultraviolet phototherapy.
- Requested device codes commonly submitted: E0691–E0694.
Conventional therapy prerequisite
An adequate trial of condition-appropriate conventional therapy (topical, systemic, biologic, or other guideline-supported treatments) is expected before authorizing home phototherapy unless contraindicated, not tolerated, or clinically inappropriate.
- Use of home UV therapy before trialing conventional therapies may render the request not medically necessary.
- Conventional options include dermatology evaluation and standard topical, systemic, or biologic treatments per guidelines.
Provide written home phototherapy plan and baseline data
The prescribing clinician must submit a written home phototherapy plan that specifies diagnosis, baseline severity or photographs, treatment area, device type/configuration, starting dose, dose escalation, treatment frequency, maximum exposure limits, missed-treatment instructions, adverse-event instructions, safety precautions, and a follow-up schedule.
- Plan must demonstrate device appropriateness for affected body surface area and include safety features and protective eyewear.
- Documentation should support training capability of member/caregiver and planned reassessment intervals (every 3–6 months).
Common denial triggers
Common reasons for denial include requests for home UVA or PUVA devices, use for tanning/wellness/cosmetic purposes, duplicate or upgraded equipment when an existing device is functional, missing clinician treatment plan or scheduled follow-up, or use when contraindications to home UV exposure exist.
- Home UVA devices and home psoralen UVA photochemotherapy are investigational/not medically necessary.
- Absence of a clinician's written treatment plan and scheduled follow-up is a frequent denial trigger.
Background
Home ultraviolet light therapy equipment delivers controlled ultraviolet radiation outside a clinical setting to treat photoresponsive skin disorders. Devices vary from handheld units to panels and cabinets and typically concentrate therapeutic output—most commonly narrowband UVB (around 311–313 nm)—to limit unnecessary ultraviolet exposure. Home devices require a clinician prescription, a written treatment plan, dosing controls and timers, safety features (for example, lockout/restricted-use capability and protective eyewear), user training, and scheduled reassessment. The policy emphasizes that office- or facility-based phototherapy should be considered first when feasible and that certain uses—such as home UVA or PUVA, cosmetic/tanning purposes, or use without clinician oversight—are not appropriate for home treatment.
