In most industries, mileage is billed at the IRS standard (~$0.67/mile). In the ambulance world, it is common to see HCPCS Code A0425 billed at $15, $30, or even $50 per mile. This isn't a typo—it's one of the primary ways providers maximize revenue.
Why the Markup?
- Heavy Equipment: An ambulance is essentially a 10,000lb mobile surgery suite. It gets poor gas mileage (often 8-10 MPG) and requires heavy-duty maintenance on brakes and tires due to the weight and high-speed emergency response driving.
- Sanitation Compliance: Every mile driven must be followed by a deep-clean and biohazard check. The cost of medical-grade disinfectants and the labor time required to turn a truck around is built into the mileage fee.
- Subsidizing "Deadhead" Miles: By law, providers can only bill you for the miles you are inside the vehicle (Loaded Miles). They cannot bill for the miles they drove to reach you or the miles they drive back to their station. If an ambulance drives 20 miles to pick you up and 5 miles to the hospital, the $30/mile rate on those 5 miles helps cover the entire 25-mile trip.
The "Short-Trip" Trap
For very short trips (under 2 miles), some private providers will charge a Minimum Mileage Fee. However, under CMS (Medicare) rules, there is no such thing as a minimum fee; you can only be billed for the actual whole miles traveled. If your bill lists "5 Miles" for a 1.2-mile trip, they are violating federal rounding standards.
The CMS Check
While private companies can charge whatever they like for mileage, the CMS 2026 Fee Schedule sets a very specific ceiling for mileage based on your zip code. If your private provider is charging 5x the CMS rate, you have a strong case for negotiation using the "Fair Market Value" argument.
