Aetna's Clinical Policy Bulletin 0813 (reviewed 2026-10-28) classifies computerized wheeze detectors—including the PulmoTrack, Personal Wheezometer, and VRIxp devices—as experimental, investigational, or unproven for diagnostic evaluation of lung sounds, cough, and all other indications due to insufficient evidence of effectiveness. Claims for these devices will be denied for Aetna members.
Aetna Clinical Policy Bulletin 0667 on esophageal and airway pH monitoring, reviewed 2026-10-07, considers esophageal pH monitoring medically necessary for listed indications, such as refractory reflux in members with chest pain after cardiac evaluation, and for evaluating vomiting in infants up to 3 months of age. The policy considers multi-channel intraluminal impedance testing medically necessary for certain reflux and dysphagia indications, and considers airway pH monitoring, pharyngeal pH monitoring and airway impedance measurement experimental, investigational or unproven. This is an older source dated 2026-10-07, which is historical material, and it states no effective date.
Aetna Clinical Policy Bulletin 0863 covers nerve blocks and lists which ones it considers medically necessary. Covered uses include adductor canal, femoral, fascia iliaca, erector spinae plane and transversus abdominis plane blocks for post-operative pain after specific surgeries, and celiac plexus block for cancer pain, while peripheral nerve blocks for chronic pain are covered only as an active component of a comprehensive pain management program. Blocks listed as experimental and investigational include genicular nerve blocks and peripheral nerve blocks used as the sole treatment for chronic non-malignant pain, because the effectiveness of these approaches has not been established.
