1/ 2017 #MSSP#ACO Results!
ACOs have scaled rapidly across the country!
In aggregate, the 472 ACOs were accountable for nearly 9 million Medicare beneficiaries and $95 Billion- that's a quarter of all fee for service, and almost half of the entire Medicare Advantage market.

Medicare shared $780 million in payments with the ACOs, netting the taxpayer $313M
