Enrolling as a Trading Partner

The Ohio Department of Medicaid (ODM) requires entities to complete an online application (Medicaid Trading Partner Form) as well as a signed Trading Partner Agreement (TPA) to initiate the process of becoming an authorized trading partner.

It can take several weeks for the TPA to be routed for approval and signatures within ODM. Once complete, the EDI Support team will notify the contacts provided on the application of the next steps.

Medicaid Trading Partner Form

This form gives ODM general information about your company (i.e. tax id., contact information, and the transactions you wish to submit/receive).
