Managed care organizations (MCO)

What they are

A managed care organization (MCO) is a health care provider, or group of medical service providers, that contracts with insurers or self-insured employers to provide managed health care services to enrolled workers. Health care services are provided through participating panel providers.

For workers

If your employer is covered by an insurer with a contract with an MCO, you may be required to pick an MCO doctor with whom to treat. The insurer may enroll you in the MCO at any time after your injury. Until you are enrolled in the MCO, you may treat with any health care provider who qualifies as an attending physician. Your doctor may continue to treat you if the doctor obtains temporary credentialing from the MCO and agrees to the MCO’s rules, terms, and conditions. For more information about what happens if you are hurt on the job, go to the injured worker overview.

For health care providers

The director of the Department of Consumer and Business Services must certify MCOs. The director cannot certify an organization that is formed, owned, or operated by an insurer or employer other than a health care provider.


The first step is to file a notice of intent form with the department.
Other certification requirements are available on the Oregon License Directory.
