Summary & Overview
HCPCS A4468: Exsufflation Belt, Includes All Supplies and Accessories
HCPCS Level II code A4468 denotes an exsufflation belt and includes all associated supplies and accessories. Exsufflation devices support airway clearance in patients with neuromuscular weakness, impaired cough, or chronic secretion retention, making this code relevant across respiratory, neurology, and home health services. Nationally, billing for wearable airway clearance devices affects durable medical equipment (DME) utilization and home-based respiratory care pathways.
Key payers considered in the review include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The analysis covers payer coverage patterns, coding and billing considerations, and the clinical contexts in which an exsufflation belt is supplied.

Clinical & Coding Specifications
Clinical Context
A 68-year-old male with advanced chronic neuromuscular disease (e.g., amyotrophic lateral sclerosis) and recurrent atelectasis is evaluated for a home exsufflation belt to augment airway clearance. The device, billed with A4468, is used in the outpatient durable medical equipment workflow: a respiratory therapist evaluates cough strength and secretion burden, the ordering clinician documents medical necessity and selects an appropriate ICD-10 diagnosis on the prescription, and durable medical equipment supplier dispenses the exsufflation belt with all supplies and accessories. Training on device use and a limited in-person or telehealth follow-up to verify fit and function are typically included in the clinical workflow. Typical site of service is the patient’s home for long-term therapy, with initial assessment often in an outpatient clinic, rehabilitation facility, or hospital prior to discharge.
