Prior authorization required for therapeutic lightbox (DME)

Aetna requires prior authorization for a high-intensity therapeutic lightbox (DME) when the selection criteria for seasonal affective disorder (SAD) are met; e.g., HCPCS E0203 (therapeutic lightbox, minimum 10,000 lux).

• Prior authorization applies when member meets DSM‑V seasonal mood disorder criteria and diagnosis requirements.

No additional explicit prior authorization rules in evidence sections

These sections of the document provide evidence summaries and references but do not state additional explicit prior authorization rules or list other CPT/HCPCS codes requiring authorization.

• Chunks referenced are background/evidence and do not specify administrative prior authorization rules.

No other explicit prior authorization requirements in administrative excerpts

The policy excerpts provided (administrative/history sections) do not describe any additional explicit prior authorization requirements beyond the DME/lightbox rule above.

• Policy history and administrative notes are present, but authorization specifics are not contained in these chunks.

No step therapy requirements specified

The policy does not specify any step therapy requirements for phototherapy; no sequencing or required trials of other therapies are mandated in the lightbox coverage criteria.

• Step therapy field in the policy is listed as “None specified.”

CBT‑I is first‑line for insomnia; light therapy not established as first‑line

For insomnia the referenced guideline recommends cognitive behavioral therapy for insomnia (CBT‑I) as first‑line; light therapy and exercise are noted as needing further evaluation rather than being first‑line monotherapies.

• CBT‑I is recommended as 1st‑line treatment for chronic insomnia in adults (strong recommendation).
• Pharmacologic therapy may be offered if CBT‑I is ineffective or unavailable; light therapy is not presented as first‑line.

No step therapy requirements in references/administrative sections

Reference and administrative sections do not impose step therapy requirements for phototherapy; no mandated trial of other agents or therapies is specified prior to coverage of the high‑intensity light unit when SAD criteria are met.

• The listed reference chunks contain citations and background but do not define step therapy sequencing.

Required clinical documentation to support SAD and device

Clinical documentation submitted must support a DSM‑V diagnosis of bipolar disorder or recurrent major depression and demonstrate a seasonal pattern of at least 2 years (seasonal depressive episodes that remit in spring and substantially outnumber non‑seasonal episodes).

• When criteria are met, documentation should also indicate the device prescribed or rented (e.g., therapeutic lightbox, minimum 10,000 lux).
• Rental of the high‑intensity light unit is covered for the first month to assess effectiveness when criteria are met.

Clinical workup documentation required for insomnia evaluation

For insomnia assessments, clinical workup documentation should include a sleep history (habits, environment, schedules, circadian factors), use of sleep questionnaires and diaries, review of somatic and mental health, physical exam and additional tests if indicated; polysomnography is indicated when other sleep disorders are suspected or in treatment‑resistant cases.

• Polysomnography is recommended for suspected other sleep disorders, treatment‑resistant insomnia, professional at‑risk populations, or substantial sleep state misperception.

Administrative/policy history notes — no additional provider documentation actions

The provided administrative and history sections contain policy history and references but do not add further specific provider documentation actions beyond the clinical documentation requirements already stated.

• Administrative notes clarify the CPB is not a contract and may be updated; they do not specify additional authorization documentation requirements.

Denial risk if selection/coverage criteria not met for E0203/A4634/96900

Claims for therapeutic lightbox (HCPCS E0203), replacement bulbs (A4634), or actinotherapy (CPT 96900) may be denied if the selection/coverage criteria for SAD are not met or if used for indications listed as experimental/investigational.

• Experimental/investigational indications include non‑seasonal depression, Parkinson disease, post‑natal depression, anorexia nervosa, dementia‑related sleep/behavioral disorders, and others listed in the policy.
• Denial risk applies when documentation does not support the DSM‑V seasonal pattern or required diagnosis.

Reference sections do not define additional authorization or denial triggers

Some evidence/reference sections included in the document are background only and do not state explicit administrative authorization or billing denial triggers.

• Use these reference sections for clinical context; they do not change the explicit prior authorization or denial rules stated elsewhere in the policy.

No new denial triggers in policy history/administrative excerpts

The policy history and administrative excerpts do not provide explicit denial triggers beyond those tied to unmet selection/coverage criteria; they list review dates and administrative notes.

• Policy history entries and additional information clarify the document’s scope but do not add authorization rules.

References/administrative sections: no step therapy specified

Reference and administrative sections confirm no step therapy requirements are specified in the policy.

Policy history and administrative notes (no new provider actions)

Administrative notes list policy review dates and history but do not change provider action requirements.
