This week, our In Focus section reviews Oregon’s Medicaid managed care environment which has been administered by risk-based provider networks, known as Coordinated Care Organizations (CCOs) since 2012. As of December 15, 2014, more than 907,000 Medicaid beneficiaries were enrolled in a CCO. On Monday, January 26, 2015, Centene Corporation announced an agreement to acquire Agate Resources, Inc., a health insurer based in Oregon that operates one of the 16 CCOs under its subsidiary, Trillium Community Health Plan. In light of that announcement, and since we haven’t written much on Oregon recently, we review the structure and current status of the CCO market in Oregon.
