What is a HCPCS Code?

Detailed Description

This code represents the mileage charge for ground ambulance transportation, calculated per statute mile (5,280 feet). It covers the distance traveled during ambulance transport and is typically billed in addition to the base ambulance service fee. This charge accounts for the operational costs associated with the distance covered during emergency or non-emergency ground ambulance services.

Additional Information
