Medicaid claims reimbursement information for organizations on behalf of Ohio Medicaid providers.
Trading Partners


As of July 1, 2021 the Ohio Department of Medicaid (ODM) will suspend new Trading Partner enrollment activity.

This suspension is expected to last through the end of the calendar year, or until the new Ohio Medicaid Enterprise System (OMES) is operational, whichever is later.  For more information related to OMES changes impacting the Trading Partner community click on the Ohio Medicaid Enterprise System tile below.

The OMES must be in a production status before new Trading Partner enrollments are resumed. This is to avoid disrupting our provider communities billing and payment of claims.

Thank you for your patience during this delay.


This information is intended to assist organizations who facilitate electronic Medicaid claims reimbursement on behalf of Ohio Medicaid providers.

NOTICE: The standing maintenance schedule for EDI transaction processing is every Sunday from 1:00 am - 5:00 am ET / EST. On the second Sunday of each month the maintenance window is expanded from midnight to 7:00 am ET / EST when needed.
OXI also has a standing maintenance window on Tuesday evenings from 7:00 pm – 11:00 pm ET / EST that could prevent submission of EDI transactions.

ODM will notify all trading partner contacts by email if unplanned or emergency maintenance occurs.
