HCPCS Code A0426: Ambulance Service, Advanced Life Support, Non-Emergency Transport, Level 1 (ALS 1)

Mileage is billed separately using A0425 with its own line item; A0426 covers the service only.

Please include both an origin/destination modifier (e.g., "RN") and either QM (under arrangement) or QN (provider-direct). For non-emergency transports, an attending physician's NPI in the claim is required.

For RSNAT services, PA must be obtained before rendering or billing from the fourth transport onward to secure Medicare coverage.
