Obstructive Sleep Apnea in Adults (CPB 0004, reviewed 2026-10-06)
Aetna considers attended full-channel polysomnography medically necessary for adults with symptoms suggestive of obstructive sleep apnea when a listed indication applies and the study is part of a comprehensive sleep evaluation with adequate follow-up, and considers unattended home sleep studies medically necessary when they use a Type II, III or IV device that measures the apnea-hypopnea index (AHI). CPAP, CPAP with pressure relief technology, autoPAP and APAP are medically necessary for members with a positive facility-based or home sleep test when the AHI or RDI is 15 or more events per hour with at least 30 events, or 5 to less than 15 events per hour with at least 10 events plus one listed condition, such as documented stroke, hypertension, ischemic heart disease, impaired cognition or mood disorders, insomnia, excessive daytime sleepiness, or more than 20 desaturations below 85% or any single desaturation below 70% during a full night study. Mandibular advancement oral appliances and FDA-approved hypoglossal nerve neuro-stimulation are considered medically necessary only when their listed criteria are met, and many other tests, devices and procedures are listed as experimental, investigational, unproven or not medically necessary.
