PriorIntel

What is this procedure?

Durable medical equipment that delivers pressurized air through a mask to keep airways open during sleep. Primary treatment for obstructive sleep apnea.

Does this require prior authorization?

Yes — Prior authorization is typically required

Step Therapy / Pre-Requirements

Requires documented diagnosis of obstructive sleep apnea via polysomnography or home sleep test with AHI ≥5. Compliance monitoring typically required at 90 days.

Common Reasons This Gets Denied

Based on insurer policy analysis and claims data patterns. Frequency indicates how often this reason appears.

CPAP prescribed without documented diagnosis of obstructive sleep apnea on sleep study (AHI ≥5)

Very Common

CPAP requires objective sleep study evidence of OSA with AHI ≥5 events/hour or ≥15 if predominantly hypopneas.

How to prevent this

Obtain in-lab PSG or HSAT with AHI ≥5; document sleep specialist review and CPAP titration study before dispensing.

CPAP mask or machine replacement requested within 5 years without documented wear time or malfunction

Common

Equipment replacement limited to 5-year intervals unless documented inadequate wear or malfunction.

How to prevent this

Maintain CPAP usage logs (>4 hours/night); document objective data card from machine; report specific malfunction to insurer.

Sleep study report with AHI ≥5 (or ≥15 if hypopnea-predominant) and documented sleep specialist review

Required

Objective diagnosis of OSA critical

Therapeutic CPAP titration study result with documented pressure setting and efficacy

Required

Establishes effective CPAP pressure and tolerance

Patient education documentation and mask fitting trial

Strongly Recommended

Shows patient counseling and equipment tolerance

Baseline oxygen saturation and AHI before CPAP initiation

Helpful

Demonstrates treatment efficacy comparison

Medical Necessity Tips

What clinical evidence supports approval

Include sleep study results showing AHI (apnea-hypopnea index)
Document patient education on CPAP use and compliance expectations
Note severity level (mild: AHI 5-15, moderate: 15-30, severe: >30)
Some plans require face-to-face evaluation within 31 days of setup
