Summary & Overview
HCPCS A0428: Ambulance BLS Non-Emergency Ground Transport
HCPCS Level II code A0428 denotes basic life support (BLS) non-emergency ground ambulance transport. This code is used for routine, non-urgent transfers where BLS-trained personnel provide patient monitoring and basic care during transport. Nationally, ambulance transport coding affects claims processing, network arrangements, and payment policy for both commercial insurers and public payers.
Key payers included in this analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of reimbursement context for BLS non-emergency transport, common billing considerations, and the clinical scenarios in which A0428 is typically applied. The publication summarizes benchmarks and rate-setting influences, identifies policy updates that commonly affect ambulance services (for example changes in Medicare ambulance fee schedules and commercial contract terms), and explains how A0428 fits into ambulance service lines and claims workflows.
The content is intended to inform revenue cycle leads, billing managers, and policy analysts about the practical role of A0428 in claims, the service settings where it applies, and the payer landscape that most often adjudicates these claims. Data not available in the input.

Clinical & Coding Specifications
Clinical Context
A 72-year-old patient residing at home requires non-emergency ground transport from a primary care clinic to a nearby outpatient imaging center for a scheduled follow-up chest X-ray after recent pneumonia. The patient is ambulatory but uses a cane and has limited endurance; the provider determines that standard commercial transport is unsuitable due to mobility limitations and risk of fatigue. The clinic arranges an ambulance basic life support non-emergency transport to convey the patient safely.
The clinical workflow: the ordering clinician documents the medical necessity for ambulance transport, including the patient’s functional limitations and inability to use public or private transportation. The ambulance operator verifies the pickup and destination addresses, confirms the patient’s stability for BLS transport, and notes any assistive devices. During transfer, BLS crew monitors vital signs and provides oxygen or basic airway support if needed. Crew documents times, patient status, provider orders, and any interventions. After arrival, the ambulance crew completes the run report and communicates any changes in condition to the receiving facility.
