Welcome to EDI Services for Oklahoma

The Oklahoma Workers' Compensation Commission (WCC) is pleased to announce a new and more efficient method for trading partners (insurers, self-insured employers, and claim administrators) to submit the employer information which is currently reported on the following WCC forms: CC-Form 2, CC-Form 2A, CC-Form 2A Extension and CC-Form 4.

Beginning January 1, 2018, electronic filing of First Report of Injury (FROI) and Subsequent Report of Injury (SROI) will become mandatory. Electronic reporting will be accomplished through EDI transmission using the Claims 3.0 reporting standards adopted by the International Association of Industrial Accident Boards and Commissions (IAIABC). Additional information can be found online at the IAIABC website, http://www.iaiabc.org

The Oklahoma WCC EDI Implementation Guide and Requirement Tables provide more information on EDI basics and required electronic documents.  

WCC has selected ISO's Workers Compensation Solutions division (ISO) to manage electronic FROI and SROI reporting. ISO will register trading partners, conduct testing, collect EDI data and submit data to WCC. 

If you have any questions or concerns regarding implementation of EDI FROI and SROI reporting in Oklahoma, please contact ISO at okwccedi@iso.com.


To register to report electronically with WCC, complete a Trading Partner Profile – New Profile located in the navigation bar on the left.  Note: WCC's Rules require a trading partner to submit a completed EDI Trading Partner Profile at least two (2) days before reporting electronically.

It is important to keep all your information up to date.  Use the Trading Partner Profile – Update Profile to change your information. 

Please be sure to check the "What’s New" section of this website, located at the top of this screen for periodic updates on technical and business requirements.
