Registration forms​

To register as an Oregon Medicaid trading partner, complete the Trading Partner Agreement for Electronic Health Care Transactions (OHA 2080).

  • Oregon Medicaid requires the original signature of the Trading Partner's Primary Authorized Signer on this form. We will not accept forms with a stamped signature or forms sent as electronic copies (i.e., faxes, emailed copies or photocopies sent by mail).
  • Learn more in How to complete the Trading Partner Agreement.

OHA policy

The EDI Administrative Rules (Chapter 943, Division 120, "Electronic Data Transmission") establish the registration process and requirements applicable to Oregon Medicaid Trading Partners or EDI submitters. They also govern the conduct and requirements for all EDI transactions with Oregon Medicaid.


Tips for submitters

  • To access your mailbox, use the host name instead of the mailbox URL. If you do not have the host name or if you have questions about this change, please have your authorized technical contact send an email to DHS.EDISupport@state.or.us.

  • Clean mailboxes regularly. Delete old files to​ make sure there is room for new transactions, including 999 and TA1 transactions.

  • Change password every 45 days. You will not get reminders to update your password ahead of time.

  • 10 failed logins will block your IP address. If you have multiple users accessing your mailbox at the same IP address, limit the number of users and/or make sure everyone knows of password changes at the same time. Make sure scripts and FTP software you use do not automatically try to reconnect after a failed login.

  • Submitters east of the Pacific Time Zone. Only send transactions when the transmission date for your zone is the same as the Pacific Time Zone.
