Yes, if the insurer submits a correction (as specified in the California Workers' Compensation Uniform Statistical Reporting Plan—1995), such as for a non-compensable claim, or if you have ownership changes, then the WCIRB may revise your experience modification. Also, if the insurer or the WCIRB reassigns the classification applicable to the business after a WCIRB inspection or test audit, then the WCIRB may revise the experience modification.
