Notice of Retraction and Replacement. Ryan and Markovitz. Estimated Savings From the Medicare Shared Savings Program. JAMA Health Forum. 2023;4(12):e234449

in JAMA Health Forum.In this study, using estimates from 2 studies and data on Medicare Shared Savings Program (MSSP) incentive payments for MSSP performance years 2013 to 2021, we found and reported that the "MSSP was associated with net losses to traditional Medicare, net savings to Medicare Advantage, and overall net savings to CMS."However, after publication of this study, I was contacted by a representative from the Medicare Payment Advisory Commission (MedPAC) who provided evidence that our calculations regarding the association between MSSP and MA benchmarks were incorrect.Apparently, MSSP incentive payments are incorporated into the US per capita cost (USPCC), which determines Medicare Advantage (MA) benchmarks.
