Federal officials announced Monday that 89 Accountable Care Organizations opened on July 1 in 40 states and Washington, DC and will serve 1.2 million Medicare beneficiaries.
Jonathan Blum, principal deputy administrator and director of the Center for Medicare, said in a teleconference that another 400 provider groups have filed notice that they will apply to be in the next wave of shared savings ACOs that become operational on Jan. 1, 2013.
"That gives us even more confidence that this program will grow over time and more organizations will come in over time," Blum told reporters at a midday teleconference.
The 89 new ACOs bring to 154 the total number of provider groups in the voluntary Medicare shared savings initiatives. That includes 32 ACOs in the Pioneer ACO Model named last December by the Center for Medicare and Medicaid Innovation, and six Physician Group Practice Transition Demonstration organizations that began in January 2011.
