Your CHA Membership

If you're a resident of Klamath County enrolled in the Oregon Health Plan (OHP), it's likely that you were automatically signed up for CHA.

CHA is a coordinated care organization (CCO). A CCO is a network of healthcare providers who work together to serve people who have OHP.

You should get your CHA new member information within 30 days of enrolling in OHP. This includes a new member welcome letter and a handbook about how to use your benefits.
