Cited policy: Aetna Clinical Policy Bulletin (Polysomnography) + Aetna Clinical Policy Bulletin (CPAP) + Aetna Clinical Policy Bulletin (Narcolepsy)

AASM/CMS-aligned. HSAT preferred when no comorbidities (Kapur 2017). Sunosi/Wakix/Xywav often require modafinil failure.

How Aetna denies sleep medicine — cpap, bipap, asv, oral appliances, inspire hns — and how to counter it

Where Aetna pushes back: 1) PSG denied — HSAT should have been done; 2) Modafinil step therapy required before Sunosi/Wakix; 3) AHI 5-14 without qualifying comorbidity.

Counter-arguments that hold up: Cite Kapur 2017 exclusions met (cardiopulmonary, neuromuscular, opioids, stroke, hypoventilation suspicion, severe insomnia). For step therapy: document modafinil/armodafinil intolerance/AEs; NT1 cataplexy → oxybate first-line per Maski 2021; pitolisant non-scheduled (HARMONY). Re-document HTN/CAD/EDS/mood comorbidity for AHI 5-14 tier.
