of health care providers who are working together for people who receive health care coverage under the Oregon Health Plan. CCOs integrate physical, mental and eventually dental care for better health, better care and lower costs. CCOs focus on prevention of illness and disease and improving care to keep patients healthy and to manage existing health conditions. The legal foundation for the OHP is generally spelled out in Chapter 414 of the Oregon Revised Statutes. Eligibility Basic eligibility requires that the applicant be a resident of Oregon, as a citizen or otherwise. The level of coverage is based on income, age, mental and physical condition. In 2014, the state implemented the Affordable Care Act's Medicaid expansion, folding previous OHP eligibility requirements into a single income requirement; up to 138% of the federal poverty level. By December 2014, enrollment in Oregon's Medicaid and CHIP programs had increased to 1,030,940 people (26% of the state population).

Managed care contractors As a Medicaid managed care system, the plan has contracts with a number of private and nonprofit companies who provide care for a capitated fee.
