HCPCS Level II code A0392 represents disposable supplies used for defibrillation as part of Advanced Life Support (ALS) services in emergency medical transport, designated for use where Basic Life Support (BLS) ambulances are not permitted to perform defibrillation.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the code’s clinical context, typical service setting, and which payers commonly adjudicate claims for ALS defibrillation supplies. The publication outlines expected benchmarks and coverage patterns where available, summarizes relevant policy considerations that affect claim adjudication, and clarifies common billing modifiers used with EMS supply codes. The content also highlights implementation issues for EMS agencies and billing departments, and notes where input data is not available for specific taxonomies, diagnosis pairings, or related codes.

This summary is written for a national audience and is intended to inform billing managers, EMS clinical leads, and payer policy analysts about the role and billing context of A0392.
