Preliminary Calculation of 2025 Ambulance Inflation Update
The AAA is projecting that the 2025 Medicare Ambulance Inflation Factor will likely be 2.6%, plus or minus 0.1%.
Section 1834(l)(3)(B) of the Social Security Act mandates that the Medicare Ambulance Fee Schedule be updated each year to reflect inflation. This update is referred to as the “Ambulance Inflation Factor” or “AIF”.
The AIF is calculated by measuring the increase in the consumer price index for all urban consumers (CPI-U) for the 12-month period ending with June of the previous year. Starting in calendar year 2011, the change in the CPI-U is now reduced by a so-called “productivity adjustment”, which is equal to the 10-year moving average of changes in the economy-wide private nonfarm business multi factor productivity index (MFP). The MFP reduction may result in a negative AIF for any calendar year. The resulting AIF is then added to the conversion factor used to calculate Medicare payments under the Ambulance Fee Schedule.
For the 12-month period ending in June 2024, the federal Bureau of Labor Statistics (BLS) has calculated that the CPI-U has increased by 3.0%.
CMS has yet to release its estimate for the MFP for calendar year 2024. Since its inception, this number has fluctuated between 0.3% and 1.2%. For calendar year 2024, the MFP was 0.4%.
Under normal circumstances, it would be reasonable to expect the 2025 MFP to be within a tenth of a percentage point or two of the 2024 MFP.
Accordingly, the AAA is projecting that the 2025 Ambulance Inflation Factor will likely be 2.6%, plus or minus 0.1%.
The AAA will notify members once CMS issues a transmittal setting forth the official 2025 Ambulance Inflation Factor.
