25 Statistics on Hospitals and RAC Audits

Staff -
CMS' Recovery Auditors — formerly known as Recovery Audit Contractors — have been conducting automated and complex reviews of Medicare payments to healthcare providers for several years now.

RACs scour a hospital's expense records looking for improper payments such as incorrect payment amounts, incorrectly coded services (e.g., MS-DRG miscoding), non-covered services, duplicative services and, in the rarer event, underpayments.


Every quarter, the American Hospital Association conducts its RACTrac Survey, in which it asks thousands of member hospitals questions on their RAC activity. More than 2,200 hospitals have participated in the RACTrac Survey since January 2010, and the AHA released its most recent survey covering the first quarter of 2012. Here are 25 statistics from the RACTrac Survey on hospitals' RAC audit activity.

1.    Roughly 87 percent of hospitals experienced RAC activity in the first quarter ended March 31, 2012.

14.    Roughly 68 percent of complex denials are short-stay medically unnecessary denials.
