Positive Pressure Ventilation (CPB 0452, reviewed 2026-07-01)
Aetna covers bilevel positive airway pressure (bilevel PAP) devices as durable medical equipment for members with restrictive thoracic disorders, severe COPD, central sleep apnea, complex sleep apnea, hypoventilation syndrome, or obstructive sleep apnea, when the medical necessity criteria for each condition are met. A bilevel PAP device with a backup rate feature is covered for these conditions only under specific criteria, and a backup rate feature has no proven value for obstructive sleep apnea. Ventilators with noninvasive interfaces are covered for severe neuromuscular disease, thoracic restrictive disease, or chronic respiratory failure from COPD where interruption or failure of respiratory support would lead to death, and noninvasive positive pressure ventilation is experimental, investigational, or unproven for asthma, pneumonia, bronchiolitis, acute lung injury and other indications not listed as covered.

Occupational Therapy (CPB 0250, reviewed 2026-05-19)
Aetna considers short-term occupational therapy medically necessary when a physician prescribes it and the member's condition can improve based on objective measures within 1 month of starting therapy, or when the therapy is needed to establish a maintenance program. Occupational therapy is considered not medically necessary once maximal therapeutic benefit has been achieved, when the condition is neither regressing nor improving, or when the member has no identifiable clinical condition. Treatments intended to improve instrumental activities of daily living, such as community living skills, home management, and leisure activities, are not covered.
