The requirements for WCIS reporting are administered by the California Division of Workers’ Compensation (DWC). The information collected is used to oversee the state’s workers’ compensation system. WCIS reporting will continue to be administered by the DWC after the WCIRB’s Indemnity Data Call requirement commences.

The requirements for the WCIRB’s Indemnity Data Call reporting are administered by the WCIRB, and the data fields that are reported were selected to meet specific needs related to the WCIRB’s ratemaking responsibilities. While the requirements for the two systems are essentially the same, certain data fields must be redacted prior to submitting California indemnity transaction data to the WCIRB. There are no major inconsistencies in which a particular field has significantly different meanings between the two systems.
