Ambulance Fee Schedules

There is a national fee schedule for ambulance services furnished as a benefit under Medicare Part B. It applies to all ambulance services, including volunteer, municipal, private, independent, and institutional providers, i.e., hospitals, critical access hospitals (except when it is the only ambulance service within 35 miles), and skilled nursing facilities.

Air and Ground ambulance mileage rates are adjusted by the yearly ambulance inflation factor (AIF). See the CMS Internet Only Manual (IOM), Publication 100-04, Medicare Claims Processing Manual, Chapter 15, Section 20.1.4 - Components of the Ambulance Fee Schedule to see how the amounts are determined.


  • 2023 = 8.7%
  • 2022 = 5.1%
  • 2021 = 0.2%

Medicare pays for "loaded" miles only. These are miles traveled while the patient is on board. Medicare does not pay for miles traveled to the point of pick up.
