The Oregon Medicaid Provider Portal will tell you whether OHA will pay or deny your claim as soon as you submit it; however, you will need to wait for your paper remittance advice (mailed the week after OHA processes your claim) to find out the exact amount paid.

OHA does not cover all valid codes, and OHA may not allow covered codes in all settings.
