A patient receives ambulance transport services. Which coding system is used to report this service?

• A. ICD-10-CM
• B. CPT
• C. HCPCS Level II
• D. ICD-10-PCS

Answer: (C)

Ambulance transport is reported with HCPCS Level II codes. This coding set covers transportation services, including ambulance services (ground and air), and the associated levels of service and mileage. The CPT system is for physician services and procedures, not transport. ICD-10-CM codes identify diagnoses, while ICD-10-PCS codes document procedures performed during inpatient stays. So for reporting an ambulance transport, HCPCS Level II is the appropriate coding system.
