Electronic Data Interchange

Setting Up Your Account

If you are a contracted provider and have not received your Internet PIN letter, please call our Internet Help Desk at (405) 522-6205 or (800) 522-0114, select option 2, then option 1 to request your PIN.

To establish your secure internet account, use your Internet PIN and log on to the SoonerCare provider portal, where you can view claim status inquiries, claim summaries, and prior authorization inquiries as described in the Provider Billing and Procedure Manual.

If you would like help setting up your website account, and/or training on secure site functions, the SoonerCare Provider Representatives are available to train your billing personnel at your facility.

Submitting claims: Direct Data Entry or Batch

With your SoonerCare Secure Site account, you can submit claims either through direct data entry or a batch file upload. With direct entry option you can submit only one claim at a time. The batch file upload allows you to combine two or more properly formatted claims and submit them at one time.

Batch upload functionality is based on the Electronic Data Interchange (EDI) technology and is the most efficient method of electronic claims submission with the Oklahoma Medicaid Management Information System (OKMMIS). It eliminates many errors, lowers operating costs, reduces turnaround time for payments, and it is free to SoonerCare (Oklahoma Medicaid) providers.
