Dobson | DaVanzo’s new evaluation of Medicare Shared Savings Program Accountable Care Organizations (ACOs) found greater savings than the Centers for Medicare and Medicaid Services (CMS) benchmark savings estimate. With the addition of 2016 data, we update our estimate and find that MSSP ACOs saved CMS $2.66B from 2013 to 2016 with net savings of $665.8M after accounting for incentive payments made by and to the program participants. Once again, these findings stand in contrast to the CMS savings calculation based on programmatic benchmarks. View the full report here. This study includes new data to make update our earlier report of PY2013-PY2015 results. These studies use standard evaluation techniques typically employed by CMS in its evaluations of the Next Generation ACO (NGACO) model, Pioneer ACOs, and other programs that do not rely on the benchmark method to estimate program effects.
