Study Shows ACOs Saved Medicare $1.84 Billion from 2013 to 2015 

NAACOS commissioned Dobson DaVanzo & Associates to conduct an independent evaluation of ACO performance using Medicare claims data from approximately 25 million beneficiaries per year. The largest evaluation to date, this study used rigorous and widely accepted statistical methods to estimate MSSP savings. After accounting for the shared-savings payments earned by ACOs, MSSP net savings reached $541.7 million in 2013–2015 — not a loss of $344.2 million as estimated by CMS.
