Medical Transportation Code Conversion: Mileage Billing Policy Update

March 9, 2016

The medical transportation code conversion was announced as effective for dates of service on or after April 1, 2015, in the March 2015 Medi-Cal Update. Providers were instructed to utilize HCPCS Level II procedure codes A0380 (BLS mileage [per mile]) and A0390 (ALS mileage [per mile]) for ambulance mileage (per statute mile) and A0425 (ground mileage, per statue mile) for litter van and wheelchair mileage. However, in order to conform to Medicare and commercial industry standard, the Department of Health Care Services (DHCS) will now use one mileage rate (HCPCS A0425) for ambulance transportation mileage.

Effective for dates of service on or after July 1, 2016, providers are instructed to begin using A0425 for ambulance transportation mileage for both emergency and non-emergency services.

Effective the same date of service, providersare also instructed to begin using A0380 for ground mileage (per statute mile) for litter van and wheelchair mileage for non-emergency services only.

Code A0390 is discontinued for dates of service on or after July 1, 2016.

Medi-Cal will continue to reimburse claims billed with codes A0380 and A0390 for ambulance mileage (per mile) and code A0425 for litter van and wheelchair mileage (per statute mile) through June 30, 2016.

The conversion is as follows:

HCPCS Code Current Billing (through June 30, 2016) New Billing (on or after July 1, 2016)
A0425 Wheelchair and litter van mileage Ambulance mileage for both emergency and non-emergency services
A0390 Ambulance ALS mileage Discontinued
