EDI Format & Transaction Codes FAQ

What EDI formats does Wisconsin use?

We use the standard International Association of Industrial Boards & Commissions (IAIABC) formats for First Report of Injury Release 1 (148, FROI, WKC-12, etc.) and Subsequent Report Release 1A (A49, SROI, WKC-13, etc.).  Please see the format spreadsheets (FROI and SROI), on this website, for the list of mandatory, optional and conditional fields for each layout.  We also use the standard IAIABC header and trailer, which is required for all transmissions.

What transaction codes does Wisconsin accept?

We will also reject transmissions with more than one payment record (e.g. intermixed TTD and TPD or TTD and PPD) because the data from such transmissions is unreliable.  You can, however, submit these transmissions via our Internet WKC-13.
