CA DWC Posts Proposed Revisions to WCIS Implementation Guide for First and Subsequent Reports of Injury


San Francisco, CA ( - The Division of Workers' Compensation (DWC) has posted a revised version of the Workers’ Compensation Information System (WCIS) California Electronic Data Interchange Implementation Guide for First and Subsequent Reports of Injury (FROI/SROI) on its rulemaking forum. Members of the public are encouraged to review the proposed regulatory revisions in the guide, and submit written comments. The comment period is open until 5 p.m. on Tuesday, October 30. 

California's WCIS uses electronic data interchange to collect comprehensive information from claims administrators to help the Department of Industrial Relations oversee the state's workers' compensation system. This information helps facilitate evaluation of the system and measure adequacy of benefits for injured workers and their dependents, and provides statistical data for research.   

The revised implementation guide contains updates and corrections to the first reports of injury and subsequent reports of injury (FROI/SROI) reporting rules of the current version that took effect in March 2018. The proposed changes address the manner of transmitting data to WCIS, the filing of SROI, requirements for specific data elements and data edits. 

Written comments can be emailed to, or mailed to: 

Division of Workers’ Compensation P.O. Box 420603 San Francisco, CA 94142 Attn: WCIS Rulemaking Forum 

The forum can be found on the DWC forums web page under “current forums.”
