Oregon's largest Coordinated Care Organization officially launched its services Saturday. Health Share of Oregon, formerly known as the Tri-County Medicaid Collaborative, is set to begin providing treatment to Medicaid patients covered by the Oregon Health Plan. Health Share of Oregon includes Adventist Health, CareOregon, Central City Concern, Kaiser Permanente, Legacy Health, Oregon Health & Science University, Providence Health & Services and Tuality Healthcare under a single umbrella organization for OHP services. CCOs offer wide-ranging care, on a continuum of treatment plans, to Medicaid patients. The state won a $1.9 billion grant to demonstrate to federal officials that the program could save billions in future medical costs.
