Is each trading partner required to send a list of FEINS for claims administrators whose data will be sent under its sender ID?
Yes. WCIS uses the claims administrator’s FEIN to process individual transactions. Transactions for unknown claims administrators will be rejected by WCIS with the error code 039-No match on database. For this reason, it is vital for each WCIS trading partner profile to be accompanied by a list of all FEINs for claims administrators whose data will be reported under a given sender ID. This list can be downloaded in Microsoft Excel format from the WCIS Web site at http://www.dir.ca.gov/DWC/WCIS.htm. If a list is not provided, WCIS will assume that the only claims administrator’s FEIN reportable by that trading partner will be the master FEIN from the trading partner’s sender ID. To prevent rejections, an updated list must be sent to your WCIS EDI contact each time there is a change.
