OHP eligibility verification

Learn how to find out an OHP client's eligibility for health care benefits.

The General Rules provider guidelines include the Oregon Administrative Rule (OAR) that requires providers to verify eligibility before providing service. 

Remember that coverage of a specific service also depends on its ranking on the Prioritized List of Health Services for the condition being treated. See the Oregon Health Plan rules, OHP Prioritized List page and Benefits and HSC List Inquiry Quick Reference PDF to learn more.

To learn more about verifying eligibility and enrollment for Health Share of Oregon members, visit the Health Share of Oregon website​.
