This annual report is developed to provide workers’ compensation professionals with a comprehensive view of California’s workers’ compensation system based on the latest available information. Top learnings from the report include:
- The California workers’ compensation system has been relatively stable in the post-pandemic era. Premium levels increased by 1 percent in 2023 and are forecast to increase modestly in 2024, while decreases in average insurer charged rates are moderating.
- Claim frequency changes in 2022 and 2023 are modest and consistent with pre-pandemic trends. The share of indemnity claims involving permanent disability has declined, but there are signs that the share of indemnity claims involving cumulative trauma is increasing.
- Average indemnity costs continue to increase, primarily driven by increasing average wage levels. Average medical costs are also increasing, driven by claims remaining open longer post-pandemic and inflationary updates to medical fee schedules. Average allocated loss adjustment expense costs rose sharply in 2022 and 2023, driven by increased litigation across the state.
- California continues to experience longer average claim duration compared to other states, driven by slower claim reporting and higher frictional costs, particularly medical-legal costs.
- The projected accident year combined ratio increased by 2 points to 111 percent in 2023, the fourth consecutive year of a combined ratio above 100 percent. Combined ratios in California continue to be above those for the rest of the country.
