Reminder update: Idaho transitions to Release 3.1 regarding First Report of Injury (FROI) and Subsequent Report of Injury (SROI) effective September 14, 2023

This is an important reminder that the Idaho Industrial Commission (IIC) will transition from Electronic Data Interchange (EDI) Claims R3.0 (FROI and SROI) to EDI Claims R3.1 (FROI and SROI) effective September 14, 2023.  Accordingly, effective September 14, 2023, use of the R3.1 standard will be mandatory for FROI and SROI reporting for all Idaho Trading Partners.

As Idaho’s transition to 3.1 heads into the final stretch, the following provides background regarding this event and outlines upcoming dates and requirements as follows:


The Idaho Industrial Commission (IIC) announced the move to R3.1 on May 12, 2021.  Initially, the release to 3.1 was scheduled for July 18, 2022, but was later changed to July 1, 2022.  On October 4, 2021, the IIC updated the release date again to December 1, 2022.  On August 5, 2022, the IIC settled on the final release date, which is September 14, 2023, along with a timeline for the transition that both Trading Partners and Vendors must comply.  Trading Partner and Vendor R3.1 FROI SROI Testing started last year on June 30, 2022.  This testing start date was initiated with the anticipation of a go live date of December 1, 2022, however, with the go live date pushed back to September 14, 2023, it has provided Trading Partners and Carriers a greater window to test.
