Summary
Attended full-channel polysomnography performed in a healthcare facility is medically necessary for diagnosing obstructive sleep apnea in adults aged 18 and older when specific criteria are met. Unattended home sleep studies using a Type II device, a Type III device, a Type IV(A) device that measures airflow and AHI, or a device with 3 or more channels including pulse oximetry, actigraphy and peripheral arterial tone (such as Watch-PAT) are medically necessary for members with symptoms suggestive of OSA. CPAP and autoPAP are medically necessary when a facility-based or home sleep test shows an AHI or RDI of 15 or greater with at least 30 events, or 5 to 14 with at least 10 events plus a listed comorbidity or excessive daytime sleepiness, and hypoglossal nerve stimulation, oral appliances and several surgical procedures are covered when their listed criteria are met.

What to do
Action · 13 steps
01Billing team: For attended full-channel polysomnography (CPT 95808, 95810, 95811), document that the test is part of a comprehensive sleep evaluation with adequate follow-up and that the member has at least one listed indication, such as moderate to severe pulmonary disease, neuromuscular disease, stroke with residual respiratory effects, epilepsy, congestive heart failure, chronic opioid medication use, super obesity, a listed comorbid sleep disorder, negative or technically inadequate portable monitoring, low pretest probability, or inability to use portable monitoring equipment safely at home.
02For home sleep testing (CPT 95800, 95801, 95806, 95807 and HCPCS G0398, G0399, G0400), document symptoms suggestive of OSA and use a device of a covered type that provides an AHI measurement, because sleep studies that do not measure AHI and oxygen saturation are considered not medically necessary.
03Repeat home sleep testing on multiple consecutive nights has no proven value.
04For PAP devices (E0601, E0470, E0472 and listed accessories such as A7030), document a positive facility-based or home sleep test that meets the AHI or RDI criteria with the required number of events, and for BiPAP, DPAP or VPAP document intolerance of CPAP or autoPAP or documented ineffectiveness, with a properly fitted interface in use without difficulty and the lower pressure settings that were tried.
05Continued PAP use beyond the initial authorization period requires a face-to-face reevaluation by the treating physician documenting improved OSA symptoms, plus objective adherence of use for 4 or more hours per night on at least 70 percent of nights during a consecutive 30-day period.
06Replacement PAP devices are covered at the end of the 5-year reasonable useful lifetime or sooner for a change in the member's condition, and replacement needed due to misuse or abuse is not covered.
07For oral appliances (E0485, E0486, K1027), document a qualifying sleep test result, and for E0485 document that the member meets CPAP criteria but is intolerant of positive airway pressure devices.
08All follow-up care during the first 90 days after the oral appliance is provided is included in the payment for the device.
09For hypoglossal nerve stimulation (CPT 64582, 64583, 64584), document every listed criterion: age 18 or older, BMI less than 40 kg/m2, a polysomnography within 24 months of the first consultation for an Inspire implant, predominantly obstructive events with central and mixed apneas under 25 percent of the total AHI, AHI of 15 to 100 events per hour, at least one month of CPAP monitoring showing CPAP failure or intolerance, absence of complete concentric collapse at the soft palate on drug-induced sleep endoscopy or flexible laryngoscopy, and no other anatomical findings that would compromise device performance.
10For palatopharyngoplasty (CPT 42145), document that CPAP or AutoPAP was attempted before surgery, with an inadequate response or intolerance despite adjustments to pressure and mask.
11For tonsillectomy (CPT 42821, 42826), the procedure is covered with UPPP only where the tonsils compromise the airway space.
12For jaw realignment surgery (CPT 21198, 21199), document that the member failed other treatment approaches for OSA.
13Dental rehabilitation used to treat OSA is not an available benefit under standard Aetna health insurance plans, and orthodontic therapy is excluded under standard Aetna medical plans regardless of medical necessity, so check the member's dental benefits for those services.
