EDI Implementation

Illinois is mandating XML reporting in the IAIABC's EDI Claims Release 3.1 Standard beginning on June 14, 2019. 

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

All trading partners submitting to the IWCC must submit an updated Trading Partner Agreement for Release 3.1 before May 17, 2019, or before the start of testing.  Trading partner and EDI vendor testing for IWCC FROI/SROI IAIABC Claims EDI Release 3.1 will begin February 25, 2019, and continue through May 24, 2019.  EDI vendors already submitting XML to at least one R3.1 EDI state at the time of testing are only required to complete connectivity testing requirements.  All other trading partners must complete the entire test plan.
