Learn how to exchange HIPAA-compliant health care transactions with OHA.

If you submit 15 or more claims a month, EDI claim submission may be right for you. Questions? Contact EDI Support Services (888-690-9888).

Choose how will you submit your EDI transactions

You can submit them directly to OHA using your current office management software, or contract with a service that transmits the EDI claims for you (e.g., a clearinghouse or billing service).

Register and test with OHA

To exchange EDI transactions with OHA, you must become a registered EDI Trading Partner. You or the service that will submit transactions for you must also register as an approved EDI submitter.

Once OHA approves your completed Trading Partner Agreement, EDI Support Services will contact your designated EDI submitters and provide them with specific instructions, logins and passwords to complete business-to-business (B2B) testing to make sure the transactions you submit can be processed by our system.

As with paper claims, before submitting EDI claims to OHA, you must verify that the client was eligible on the date services were provided.
