Medicare Fee for Service Recovery Audit Program
Do you have questions or concerns about the Recovery Audit Program? Please e-mail us at RAC@cms.hhs.gov. Please Do Not send Personal Health Information to this e-mail address.
The Medicare Fee for Service (FFS) Recovery Audit Program’s mission is to identify and correct Medicare improper payments through the efficient detection and collection of overpayments made on claims of health care services provided to Medicare beneficiaries, and the identification of underpayments to providers so that the CMS can implement actions that will prevent future improper payments in all 50 states.
What does a Recovery Audit Contractor (RAC) do?
The RACs conduct both complex and automated post-payment reviews. Automated reviews occur at the system level while complex reviews require a qualified individual to review the medical record. In order to obtain the medical record and any supporting documentation, the RAC shall issue an Additional Documentation Request (ADR). For more information regarding ADRs, please visit: https://www.cms.gov/research-statistics-data-systems/medicare-fee-service-compliance-programs/medical-review-and-education/additional-documentation-request
