Do you have questions or concerns about the Recovery Audit Program? Please e-mail us at 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:

Recent Updates

March 28, 2023 - On March 24, 2022, CMS awarded Performant Recovery, Inc., the new Recovery Audit Contractor (RAC) Region 2 contract.  RAC Region 2 includes the following Medicare Administrative Contractor (MAC) jurisdictions: J5, J6, and JH.

Cotiviti, LLC, the RAC previously responsible for reviews in Region 2, remains under contract with CMS to support the RAC Program from an administrative and appeals perspective in this region. Please contact Cotiviti in regards to reviews conducted by Cotiviti. All notification of improper payments, including review results letters (complex reviews), informational letters (automated reviews) and no findings letters (complex reviews) were completed by Cotiviti, in Region 2, on or before Friday, September 16, 2022.

CMS anticipates Performant will begin reviews in the Spring (2023). RAC Region 2 providers can rely on the review completion date specified in the review results letter, as well as the RAC’s name on the letter, to identify which contractor to reach for inquiries.  If Performant receives inquiries in regards to reviews conducted by Cotiviti, Performant customer service will inform providers to reach out to Cotiviti and vice versa.

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.
