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?

RAC's review claims on a post-payment basis. The RAC's detect and correct past improper payments so that CMS and Carriers, FIs, and MACs  can implement actions that will prevent future improper payments.

Recent Updates

March 26, 2021, CMS awarded Performant Recovery, Inc., the incumbent, the new RAC Region 1 contract.

April 24, 2019 - CMS often receives referrals of potential improper payments from the MACs, UPICs, and Federal investigative agencies (e.g., OIG, DOJ). At CMS discretion, CMS may require the RAC to review claims, based on these referrals. These CMS-Required RAC reviews are conducted outside of the established ADR limits.

December 21, 2018 - The CMS has posted an updated version of the Institutional-Provider-Facilities-ADR-Limits document (/Research-Statistics-Data-and-Systems/Monitoring-Programs/Medicare-FFS-Compliance-Programs/Recovery-Audit-Program/Resources). This update changes the ADR “cycle” limit, from zero (0) to one (1), for those providers who, under the previous methodology would have an ADR “cycle” limit of zero (0), even though their “annual” ADR limit was greater than zero (e.g. 1, 2, 3, or 4).

May 17, 2018 - We’ve updated this Medicare Fee for Service Recovery Audit Program website to include new pages for Approved and Proposed RAC review topics. These lists will be updated on a monthly basis. All downloadable documents can now be found on our Resources page.

January 29, 2018 - An updated version of the Institutional Provider (Facilities) ADR Limit document is available in the Downloads area of the Provider Resource webpage. The updated version includes additional information on how Provider Denial Rates are calculated, for Risk-Based, Adjusted ADR Limits.

December 7, 2016 - CMS has posted the Fiscal Year 2015 Recovery Audit Program Report to Congress in the Downloads section of the Recovery Audit Program's main page. CMS has also posted the FY 2015 Recovery Audit Program Appendices, as a companion to the Report.

November 24, 2017 - An updated document, listing the Recovery Audit Program Improvement and their respective implementation (effective) dates is now available in the Download area of the Program Reports webpage.

November 9, 2017 - CMS has begun, as of today, to put a list of review topics that have been proposed, but not yet approved, for RACs to review. These topics will be listed, on a monthly basis, on our Provider Resources page along with details about the proposed reviews.
