We evaluated both the Center for Medicare and Medicaid Services Innovation Center (CMS Innovation Center) models and the Medicare Shared Savings Program (MSSP) and found that they have generated gross savings for all beneficiaries in the Traditional Medicare program while demonstrating positive impacts on selected quality measures. Between 2012 and 2022, 19 selected CMS Innovation Center models generated an average annual savings ranging from $23 to $31 per beneficiary per year, amounting to $0.70-$1.0 billion in annual gross savings and total gross savings of $7.7 – $11.0 billion between 2012 and 2022. Between 2012 and 2022, MSSP generated an average annual savings ranging from $68 to $94 per beneficiary per year, amounting to $2.1- $2.9 billion in annual gross savings and total gross savings of $23 – $31 billion between 2012 and 2022. Most of the estimated reductions in Medicare spending from Innovation Center models were attributed to counties that attained or maintained relatively high levels of model penetration over the study period.
