HCPCS Level II code A0160 denotes non-emergency transportation billed on a per-mile basis when provided by a case worker or social worker. This code is used to capture mileage for community-based, non-emergency conveyance to medical appointments or social services and supports coordination of care and access for patients who lack other transportation options. Nationally, accurate use of this code affects access to services for vulnerable populations and contributes to care coordination metrics and cost-of-care reporting.

Key payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the code’s clinical intent, typical sites of service, common billing modifiers and procedural context, and comparative payer coverage considerations. The publication also summarizes benchmarks for utilization, documentation expectations, and policy updates that influence when and how mileage-based transportation is billed. Practical clinical context clarifies scenarios in which a case worker or social worker provides transport and when per-mile billing applies.

This summary is written for a national audience and focuses on billing definition, payer considerations, and operational implications for providers and administrators seeking clarity on appropriate claim reporting for non-emergency, per-mile transportation by social service staff.
