EDI Implementation

Illinois Workers’ Compensation Commission (IWCC) will be adopting the IAIABC R3.1 FROI/SROI XML standard beginning September 9, 2024. As of the go live date, all Trading Partners and Vendors will be expected to send filings in the IAIABC R3.1 XML format. After Go Live, the ACORD XML file format will no longer be accepted by the IWCC.

The updated Release 3.1 trading partner tables and matrix are now available:

IWCC Trading Partners (Direct SFTP) and EDI Vendors who are currently sending files in IAIABC R3.1 FROI/SROI XML format to other jurisdictions will be expected to send at least 1 FROI and 1 SROI file for Connectivity Testing only. Any new Vendors or Direct Filers reporting EDI filings to the IWCC will be expected to complete the full IWCC test plan, which is available on the state’s website at this location: (https://iwcc.illinois.gov/ediimplimentation.html). The Test Plan and the Implementation Timeline are also attached to this message for convenience. The IWCC test environment is available starting May21, 2024.
