Surgical Management of Sleep Disorders 7.01.41
Policy 7.01.41, Surgical Management of Sleep Disorders, is effective January 22, 2026. It states that hypoglossal nerve upper airway stimulation is medically appropriate for moderate-to-severe obstructive sleep apnea (OSA) when all listed criteria are met for each age group, and that hypoglossal nerve or upper airway treatment of OSA that does not meet those criteria is investigational.

Sleep Studies 2.01.28

It states that a facility-based CPAP titration study is medically appropriate when PSG criteria are met and the individual has co-morbid conditions with a positive OSA diagnosis, central or mixed sleep apnea, significant hypoxemia, or oxygen deficiency requiring supplemental oxygen. The 01/22/26 annual review left policy intent unchanged.

Motor Cortex Stimulation (CPB 0755, reviewed 2026-10-21)
Aetna's Clinical Policy Bulletin 0755 says Aetna considers motor cortex stimulation experimental, investigational, or unproven for the listed indications because its effectiveness has not been established. The listed indications include amyotrophic lateral sclerosis, autism spectrum disorder, cerebral palsy, chronic refractory pain, depression, dysphagia, Parkinson's disease, post-stroke aphasia, post-stroke hemiparesis, seizures, traumatic brain injury and obsessive compulsive disorder, and the bulletin says that list is not all-inclusive.

Motor Cortex Stimulation (CPB 0755, reviewed 2026-02-24)
Aetna's Clinical Policy Bulletin 0755 on motor cortex stimulation, with a policy history last review of 10/21/2026, considers motor cortex stimulation experimental, investigational or unproven for many indications because its effectiveness has not been established. The list includes amyotrophic lateral sclerosis, autism spectrum disorder, cerebral palsy, chronic refractory pain (such as central pain syndromes, complex regional pain syndrome, phantom limb pain, thalamic pain and trigeminal neuropathic pain), depression, dysphagia, dystonia secondary to a focal basal ganglia lesion, movement disorders, obsessive compulsive disorder, Parkinson's disease, post-stroke aphasia, post-stroke hemiparesis, seizures, traumatic brain injury, and use of motor cortex stimulation during deep brain stimulator implantation. The policy lists CPT codes 61850, 61860, 61885, 61886, 64568, 95961, 95962 and 95970 as not covered for the indications it lists.
Aetna · Identified Aug 14, 2026Medium impact
Pulse Oximetry and Capnography for Home Use (CPB 0339, reviewed 2026-05-21)
Aetna covers home pulse oximetry as durable medical equipment for members with chronic lung disease, severe cardiopulmonary disease, or neuromuscular disease involving the muscles of respiration, when the device is used to determine home oxygen liter flow for ambulation, exercise, or sleep, to monitor a person on a home ventilator, for short-term (one month) monitoring when a physician-directed change in home oxygen liter flow is needed, when weaning from home oxygen, or for interstage monitoring of children undergoing the Norwood procedure for hypoplastic left heart syndrome. Capnography (end-tidal carbon dioxide monitoring) is covered for members with congenital central alveolar hypoventilation syndrome. Home pulse oximetry is considered experimental, investigational, or unproven for asthma management, for evaluating and teaching CPAP, for maintenance or continuous monitoring other than for persons on a ventilator, for predicting the need for adenotonsillectomy in children, and when used alone as a screening or testing technique for suspected obstructive sleep apnea.
Aetna · Identified Aug 12, 2026Medium impact
Acoustic Pharyngometers and SNAP Testing System (CPB 0336, reviewed 2026-05-20)
Aetna considers SNAP Testing using 3 or more channels a medically necessary device for home diagnosis of obstructive sleep apnea in adults, according to the criteria in CPB 0004, and lists HCPCS G0400, a home sleep test with a type IV portable monitor using a minimum of 3 channels, as covered for adults only when selection criteria are met. Acoustic pharyngometry, such as the Eccovision Acoustic Pharyngometer, and SNAP Testing System versions using fewer than 3 channels are considered experimental, investigational, or unproven for screening, diagnosis, treatment planning, or prediction of surgical success in persons with suspected or known obstructive sleep apnea, and for all other indications. The policy lists no specific CPT or HCPCS code for acoustic pharyngometry.
