What Highmark's policy requires for ent / otolaryngology — sinus surgery, septoplasty, tonsillectomy, head & neck

Cited policy: Anthem BCBS medical policy Treatment of Obstructive Sleep Apnea (UPPP, MMA, Hypoglossal Nerve Stimulation)

HGNS (Inspire) per FDA labeling P130008: AHI 15-65 with <25% central; BMI <=40 (per 2023 expanded labeling); failure or intolerance of PAP after >=3 mo trial; DISE without complete concentric collapse at the velum. Pediatric Down syndrome per 2017 expansion.

How Highmark denies ent / otolaryngology — sinus surgery, septoplasty, tonsillectomy, head & neck — and how to counter it

Where Highmark pushes back: 1) PAP trial not documented for >=3 mo; 2) BMI exceeds plan-specific cap; 3) DISE not performed; 4) AHI outside 15-65; 5) Plan still cites pre-2023 BMI cap of 32-35.

Counter-arguments that hold up: Submit CPAP/BiPAP usage data (compliance <4 hr/night) or mask intolerance/aerophagia documentation. Cite STAR Strollo NEJM 2014 + 5-yr Woodson 2018 + ADHERE Registry. Cite FDA P130008 expanded indications (2023) — most plans have not yet updated; reference current FDA labeling. Submit DISE report excluding complete concentric velar collapse. Cite AAO-HNS / AASM Position on HGNS.
