Modifier and Units reporting on CMS 1450 FORM


C. Modifier Reporting

Providers must report an origin and destination modifier for each ambulance trip provided and either a QM (Ambulance service provided under arrangement by a provider of services) or QN (Ambulance service furnished directly by a provider of services) modifier in FL 44 “HCPCS/Rates".


D. Service Units Reporting

For line items reflecting HCPCS codes A0426, A0427, A0428, A0429, A0430, A0431, A0432, A0433, or A0434, providers are required to report in “Service Units” for each ambulance trip provided. Therefore, the service units for each occurrence of these HCPCS codes are always equal to one. In addition, for line items reflecting HCPCS code A0425, A0435, or A0436, providers must also report the number of loaded miles.

E. Total Charges Reporting

For line items reflecting HCPCS codes A0426, A0427, A0428, A0429, A0430, A0431, A0432, A0433, or A0434, providers are required to report in Total Charges the actual charge for the ambulance service including all supplies used for the ambulance trip, but excluding the charge for mileage.

For line items reflecting HCPCS codes A0425, A0435, or A0436, providers are to report the actual charge for mileage.


NOTE: There are instances where the provider does not incur any cost for mileage, e.g., if the beneficiary is pronounced dead after the ambulance is called but before the ambulance arrives at the scene. In these situations, providers report the base rate ambulance trip and mileage as separate revenue code lines. Providers report the base rate ambulance trip in accordance with current billing requirements. For purposes of reporting mileage, they must report the appropriate HCPCS code, modifiers, and units. For the related charges, providers report $1.00 in non-covered charges. A/B MACs (A) should assign remittance adjustment Group Code OA to the $1.00 non-covered mileage line, which in turn informs the beneficiaries and providers that they each have no liability.
