Mailbox access changes effective January 1, 2016

The Oregon Health Authority is changing the way its trading partners access their EDI mailbox. This change will help ensure access to the mailbox in the event of a disaster.

In a transition that began January 1, 2016, partners will 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

Please note that this change does not apply to the Provider Web Portal at https://www.or-medicaid.gov.

Registration forms​

To register as an Oregon Medicaid trading partner, complete the EDI Registration Packet (2080, 2081 and 2082, described below).

  • Oregon Medicaid requires the original signature of the Trading Partner or Authorized Signer on all forms. We will not accept forms with a stamped signature or forms sent as electronic copies (i.e., faxes or e-mailed copies).
  • Learn more in How to complete the EDI Registration Packet.

OHP 2080 (Packet Pages 1-5)

All Trading Partners must sign a TPA in order to do business electronically with Oregon Medicaid. If your trading partner name, Tax ID and/or Oregon Medicaid provider number changes, you will need to submit a new TPA.

OHP 2081 (Packet Pages 6-8)

Exhibit A of the TPA gives Oregon Medicaid information on who will be submitting your electronic transactions.​

OHP 2082 (Packet Pages 9-10)

Exhibit B of the TPA tells Oregon Medicaid which electronic transactions that you or your electronic submitters want to register for. ​

OHP 2083

Use Exhibit C to update contact information listed on Exhibit A and add or delete your registered transaction on Exhibit B. ​


To register as an Oregon Medicaid trading partner, complete all three forms in this packet (2080, 2081 and 2082).​

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

  • 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.
