Trek Health ingests and normalizes Transparency in Coverage data and payer policy updates to give provider organizations a clear view of how commercial reimbursement behaves across markets, payers, and services. Our platform transforms raw payer disclosures into structured intelligence that supports contract evaluation, payer negotiations, and service line strategy. By combining market benchmarks with ongoing policy visibility, Trek helps teams identify variability, risk, and opportunity in commercial reimbursement. The result is faster insight, stronger negotiating positions, and more informed financial decisions.

Coverage Criteria for Facility-Based Sleep Testing

Form-based clinical criteria for authorization

Authorization should be supported when documentation demonstrates relevant clinical indications from the completed authorization form.

Acceptable reasons for facility-based initial NPSG/LST: Pediatric/adolescent patients; significant cardiac disease (CHF NYHA III/IV, uncontrolled arrhythmia, pulmonary hypertension, recent MI within 6 months); chronic pulmonary disease requiring oxygen, obesity hypoventilation, or uncontrolled lung disease; neurologic disorders (prior CVA/TIA, nocturnal seizures, Parkinson's disease, amyotrophic lateral sclerosis or other neurodegenerative disorders); elevated Epworth Sleepiness Score; other comorbid conditions.

Provider must indicate specific items on form

Complex sleep disorder indicators: Narcolepsy; parasomnias; periodic limb movement disorder; central sleep apnea; BMI > 50; prior inconclusive home testing; lack of mobility/dexterity; cognitive impairment; other specified reasons.BMI > 50

These items on the form support the need for in‑lab testing

Split-night study criteria: AHI > 40 in the first 2 hours AND CPAP nearly/eliminates respiratory events during non/REM sleep AND CPAP titration > 3 hours.AHI > 40 in first 2 hours; CPAP titration > 3 hours

All three check-box items are listed on the form to justify split‑night diagnostic plus titration

Reasons for repeat NPSG/LST: Assess continued need for CPAP; assess need to change positive airway pressure settings; failed APAP/CPAP or symptom recurrence; confirm presence of OSA prior to upper airway surgery; failed split‑night NPSG; other specified reasons.

Provider must check applicable reason(s) on the form

The form specifies that Multiple Sleep Latency Testing (MLST) is indicated only for narcolepsy. When MLST is requested, the ordering provider must document narcolepsy as the clinical indication on the completed form to support authorization.

The form clearly states that authorization is not a guarantee of payment. Even if an authorization number and dates of service are issued, payment is contingent on meeting coverage and documentation requirements; requests that do not meet clinical indications documented on the form may be denied and will result in a denial notice.

Provider Responsibilities and Authorization Process

Prior Authorization

Prior Authorization Required

Prior authorization is required for attended full-channel nocturnal polysomnography (NPSG)/laboratory sleep test (LST) and multiple sleep latency testing (MLST). Submit the completed authorization form to the Utilization Management Department (fax/phone on form). Please refer to Neighborhood's Clinical Medical Policy on www.nhpri.org for additional coverage criteria.

Attended full-channel NPSG/LST — prior authorization required
MLST (only for narcolepsy) — prior authorization required
Return completed form to Utilization Management at (401)459-6023

Documentation Required

Required Documentation on Authorization Form

The authorization request must include complete member, provider, and clinical information on the authorization form. Incomplete forms may result in delays or denial.

Background

The authorization form captures the specific clinical reasons that justify facility-based sleep testing. It lists selectable indications such as an attended full-channel nocturnal polysomnography (NPSG)/laboratory sleep test and documents clinical data needed to justify in-lab testing (for example, suspected obstructive sleep apnea, complex sleep disorder indicators including narcolepsy, high BMI, prior inconclusive home testing, and other comorbid conditions). Providers must complete these sections to show the clinical rationale for ordering an in-lab study.
