G0237 Insurance Policy Changes

Chest Physiotherapy and Airway Clearance Devices (CPB 0067, reviewed 2026-03-18)

Aetna consolidated three prior chest physiotherapy and airway clearance policies (CPBs 252, 280, 333) into one comprehensive policy (CPB 0067). This policy consolidation clarifies medical necessity criteria for respiratory therapist services, establishes specific indications for airway clearance devices (Flutter, Acapella, mechanical percussors, PEP masks, postural drainage boards), defines requirements for high-frequency chest compression systems, and identifies experimental/investigational devices. Billing teams must verify coverage based on diagnosis, device type, and documented clinical criteria before claim submission.
