Recovery Audit Contractor (RAC)

Recovery Audit Contractors (RAC) identify improper Medicare payments made on healthcare claims. These audits may result in the identification of Medicare overpayments and/or underpayments. Providers that may be reviewed include hospitals, physician practices, nursing homes, home health agencies, durable medical equipment suppliers and any other provider or supplier that bills Medicare Part A and Part B.

RACs identify specific issues to pursue but are limited to claims approved through the CMS "new issue review" process. In some cases, a small number of "non-posted issue" requests may be requested from providers as the Recovery Audit Contractor requests sample data to supply to CMS on an issue the RAC would like approved. Prior to a widespread review, all approved issues are posted on the Recovery Audit Contractor’s website. Noridian urges providers to stay informed of the new issues that are identified by the RAC contractor.
