HCPCS Level II code A4614 denotes a hand-held peak expiratory flow rate meter, a durable medical device used to measure peak expiratory flow for monitoring airway function. This code is relevant nationally for clinicians managing obstructive lung diseases, durable medical equipment suppliers, and payers that cover home or clinic-based respiratory monitoring equipment. The device supports objective assessment of airflow variation, treatment response, and self-management for patients with asthma and other conditions affecting expiratory flow.

Key payers covered in this overview include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of what the code represents and its typical clinical and service contexts. The publication also provides benchmarks and payment context where available, coding considerations for billing durable medical equipment, and the clinical scenarios in which a hand-held peak expiratory flow meter is commonly used. Policy updates and payer coverage nuances that affect reimbursement and documentation expectations are summarized to inform billing, DME suppliers, and clinical administrators.
