How to Check Claim Status

MMIS Provider Portal

The Provider Portal at https://www.or-medicaid.gov allows you to view PDF versions of the paper remittance advice. You can also review and adjust, void or resubmit claims as necessary. For more information, view the Claim Adjustment Handbook and the step-by-step instructions. 

Accessing the portal

To use the portal, you will need:
  • The PIN letter issued by Oregon Health Authority when you enrolled as an Oregon Health Plan provider; or
  • Permission from the person in your organization that manages access to the portal.

To learn more, visit the Provider Portal Resources page.

Searching for claims 

View the step-by-step instructions or see page 5 of the Claim Adjustment Handbook.

Remittance Advice

Learn how to read and take action on the claim status information listed in this automated notice from OHA.

Information in the RA will appear in the following order, as applicable. 

​

If you have the "Online RA" role in the Oregon Medicaid Provider Portal at https://www.or-medicaid.gov, you can stop the paper RA by clicking the "Stop Paper RA" button when you first access the Online RA screen.

If you do not have Provider Portal access, you can also contact Provider Enrollment (800-336-6016) and ask to stop receiving the paper RA. Please provide the Provider ID listed in the "Payee ID" or "NPI ID" field in the top right corner of the paper RA.​

Other Ways to Get Claim Status Information

These systems use HIPAA-compliant Claim Adjustment Reason Codes and/or Remittance Advice Remark Codes to describe the status of a claim.
  • Automated Voice Response (866-692-3864) will read you information about the first six claims for the ICN or client ID you request claim status on. After that, you need to use the Oregon Medicaid Provider Portal for additional information. For more information, refer to the AVR Quick Reference.
  • Electronic Remittance Advice (ERA or 835 transaction) – Through OHA or a registered clearinghouse. Current electronic data interchange trading partners can sign up for the electronic RA (check the box for "835 Health Care Claim Payment/Advice"). Providers new to EDI can learn how to get started.
