Covered when criteria met

Phototherapy is covered for treatment of seasonal affective disorder or other depressive disorders when supplied by a DME provider with a physician's order.

Covered Indications: Phototherapy is covered for the treatment of seasonal affective disorder (SAD) or other depressive disorders.

Applies to Medicare Advantage and Commercial Products; device must be supplied by a DME provider with a physician order.

Clinical diagnosis requirement: Member is diagnosed with bipolar disorder or recurrent major depression and meets DSM-V criteria for a seasonal mood disorder (at least 2 years of seasonal depressive episodes that remit in spring and substantially outnumber non-seasonal episodes).

Policy references DSM‑V seasonal mood disorder diagnostic requirement for recommending phototherapy.

Supplier and order requirement: Phototherapy lights require a physician's order and must be supplied by a Durable Medical Equipment (DME) provider to be reimbursable.

Members are not eligible for reimbursement for devices purchased outside of a DME supplier (e.g., internet or local merchant).

Members are not eligible for reimbursement for phototherapy lights purchased from non‑DME sources. Phototherapy devices must be supplied by a Durable Medical Equipment (DME) provider per the policy and are not reimbursable if purchased elsewhere (for example, via the internet or a local merchant).

Currently, no phototherapy device has received final market approval from the U.S. Food and Drug Administration (FDA) for the treatment of seasonal affective disorder or other depressive disorders. Despite the lack of FDA approval for this indication, commercial light boxes, visors, and other supplemental light delivery devices are available on the market.

Provider Requirements and Actions

Prior Authorization

Prior authorization not required

Prior authorization review is not required for phototherapy devices; providers do not need to obtain prior authorization for covered phototherapy lights (E0203, A4634) when other policy conditions are met.

Covered codes include E0203 and A4634 — see Coding section.

Step Therapy

No step therapy specified

No step therapy requirements are specified in this policy; phototherapy is presented as a treatment option alongside medications for seasonal affective disorder and other depressive disorders.

Documentation Required

Physician order and DME supplier required

Phototherapy lights require a physician's order and must be supplied by a Durable Medical Equipment (DME) provider; covered HCPCS codes (e.g., E0203, A4634) are reimbursable to DME providers only when these conditions are met.

Ensure a physician order is documented in the medical record.
Submit claims using the covered DME HCPCS codes and bill to the DME supplier.
Reimbursement is limited to DME providers — do not bill as a non-DME supplier.

Denial Risk

No reimbursement for lights purchased elsewhere

Members are not eligible for reimbursement for phototherapy lights purchased from other sources (for example, internet retailers or local merchants); items purchased outside the DME supplier pathway will not be reimbursed.

Background and Clinical Context

Seasonal affective disorder (SAD) is a recurrent form of major depression that occurs on a cyclical basis related to decreased ambient light in winter months. It presents with features similar to major depressive disorder but with a seasonal pattern. Bright white light phototherapy—delivered by a light box (or light visor)—is an established treatment option for SAD and is frequently used alongside medications.

Phototherapy is typically administered daily with the patient positioned a specified distance from the light source for a period usually ranging from about 30 minutes to several hours, continued for days to weeks until an adequate antidepressant response is achieved; treatment may be repeated for relapse. Per policy, phototherapy requires a physician's order and must be supplied by a DME provider to be eligible for coverage.

Definitions

Phototherapy — description and clinical use

Definition of phototherapyDelivery of supplemental bright white light by a light box or light visor to treat seasonal affective disorder and depressive disorders.

Typical intensity used clinically>= 2,500 lux for bright white light (equivalent to a bright summer day)

Typical administrationPatient remains a specified distance from the lightbox for usually 30 minutes to several hours daily until response; treatment can be repeated for relapse.

Seasonal mood disorder (DSM‑V criteria)

DSM‑V seasonal mood disorder criterionAt least 2 years of seasonal depressive episodes that completely remit when daylight increases in spring and substantially outnumber any non‑seasonal depressive episodes.

Diagnostic contextMember must be diagnosed with bipolar disorder or recurrent major depression and meet DSM‑V seasonal pattern criteria to be recommended for phototherapy.

Typical clinical courseEpisodes recur on a cyclical basis related to decreased ambient light during winter months; phototherapy is recommended alongside other treatments.

Phototherapy Treatment Modalities

Phototherapy (light box, light visor)

Phototherapy modality: Bright white light delivered by a light box or light visor; covered examples and coding focus on tabletop therapeutic lightboxes supplied as DME.

Background discusses visors and other variants, but policy defines phototherapy as delivery of supplemental bright white light by a light box and reimburses DME‑supplied devices.
