RE: OIG Report on Utilizations of Medicare Ambulance Transports

On September 24, 2013, the Office of the Inspector General (OIG) issued a report entitled Utilization of Medicare Ambulance Transports 2002 – 2011, OEI 09-12-00350. The report lists the increases in ambulance transports and suppliers paid by Medicare Part B fee-for-service from 2002-2011, comparing many different categories. The report does not make any recommendations, nor does it look at the factors that could lead to certain increases (e.g. new suppliers, population shifts, etc). This is the type of report that policymakers read so the AAA is currently developing a response to the report that does examine factors for some of the increases.

OIG Regional Inspector General Timothy Brady will be speaking on the findings of this report at the AAA Annual Conference in Las Vegas in November. Mr. Brady will also present on questionable billing characteristics in 2011 and case studies of fraudulent providers and actions by the OIG to prevent and reduce waste, fraud and abuse. The presentation will be a general session held on Tuesday, November 19, at 11:00 am local time. For information on registering for the AAA Annual Conference, please go to:
