Coverage Summary

This policy covers the use of home phototherapy (portable ultraviolet light therapy devices including UVB and PUVA) for dermatological conditions and is effective 2026-06-21. The overall stance: home phototherapy is not covered except when specific criteria are met; the policy notes a lack of evidence that home-based PUVA or other home ultraviolet therapies are as safe or effective as office-based treatment and considers home use a convenience to the member and therefore not covered.

Coverage Determination / Medical Necessity

Coverage Determination

Phototherapy in the home for the treatment of dermatological conditions is covered only when criteria are met; otherwise not covered. (Policy states lack of evidence for home-based phototherapy safety/effectiveness.)

Not covered — home-based UV therapy: Home-based PUVA or any other home-based ultraviolet light therapy for treating dermatological conditions is not covered due to lack of evidence that it is as safe or effective as office-based treatment.
Considered convenience: Use of home phototherapy is considered a convenience for the member and therefore not covered.

Denial Risk

Potential claim denial for home phototherapy

Claims for home-based ultraviolet phototherapy (including PUVA and other home UV light therapies) are not covered and may be denied as not medically necessary. Providers should not bill members for these services unless there is a written agreement for non-covered services.

Billing Rule

Device billing

If billed, report HCPCS codes E0691–E0694 as appropriate. Policy lists E0691 (ultraviolet light therapy system, treatment area 2 sq ft or less) and explicitly identifies E0692, E0693, and E0694 as not covered for home phototherapy.

Background & Evidence

Home phototherapy units emit high-intensity ultraviolet light and are intended to treat various skin diseases; at least one device (the Levia personal targeted UVB device) was cleared by the U.S. FDA through the 510(k) process for home treatment of psoriasis. Evidence is mixed: some randomized trials (for example, an oral PUVA at-home study for chronic hand eczema) showed comparable clinical improvement to hospital-administered therapy, but reviewers and guideline authors have noted limited data and the need for further validation. Safety and monitoring concerns—such as the need for regular dermatologist skin examinations to detect early skin cancers and the risk of unmonitored radiation exposure—argue against routine home PUVA or unsupervised home ultraviolet therapy.

Evidence	Key detail
Randomized trial	van Coevorden et al (2004): open-label RCT (n=158) comparing oral PUVA at home with hospital-administered bath PUVA for chronic hand eczema; both groups showed comparable and substantial clinical improvement; authors noted results need validation.
Systematic/Review	2010 review and other literature: limited evidence for home PUVA; safety and monitoring concerns (need for clinician skin exams) and no studies comparing home-based PUVA with office-based PUVA identified.

Home phototherapy: use of portable ultraviolet light therapy devices (for example, UVB or PUVA units) in the patient's home for treatment of dermatologic conditions; these devices typically contain multiple fluorescent lights that emit high-intensity, long-wave ultraviolet light for medical treatment of skin diseases.
