A new report shows the state's CCO's are helping direct these Medicaid patients to primary care doctors as opposed to the E-R.
They found that E-R visits were down by 13 percent during the first nine months of 2013.
Lori Coyner with the Oregon Health Authority, belives these numbers show these CCO's are working.
"Yes, we do think the reduction in ER visits is a reflection of CCOs. As Medicaid expands over 2014, we think this trend will continue and the innovation at the local level is very encouraging."
A Harvard study released earlier this year found the opposite result. They followed Medicaid patients in 2008 and found an increase in ER visits.
But Coyner says that was before the state had CCO's and they do a very effective job of directing patients to where they need to go. She believes that's why the ER visits are significantly down.
