Total costs per claim for lost-time injuries in California grew at a sustained pace from 2022 to 2025, with indemnity benefits, medical payments and benefit delivery expenses all contributing to the increase, according to the Workers Compensation Research Institute.

Total costs per claim in California for workers’ compensation claims with more than seven days of lost time grew 6% in 2025, continuing a pattern of similar growth over the previous two years, the WCRI found in its 2026 CompScope Benchmarks for California. The growth rate was fairly typical when compared with 17 other study states, where annual increases ranged from 4% to 14% over the 2022-2025 period, the WCRI said.

All three key cost components contributed to the trend in California. Indemnity benefits per claim rose 4% in 2025, medical payments per claim climbed 7%, and benefit delivery expenses per claim jumped 9%, according to WCRI.

Indemnity Growth Moderates but Remains Persistent

California indemnity benefits per claim grew at a more moderate pace in 2025 compared with the 7% to 8% annual increases recorded from 2022 to 2024, the report said. Growth in wages of injured workers was a persistent driver, with average weekly wages rising 3.5% for workers injured in 2024, somewhat less than in prior years and potentially reflecting a cooling labor market, according to WCRI.

California’s unemployment rate gradually increased from late 2023 through 2025, ranking among the highest in the country, the report noted. Job openings returned to pre-pandemic levels after a period of historically tight labor market conditions.

Minimum wage increases also played a role. California’s state minimum wage stood at $16.50 as of Jan. 1, 2025, with special rates for fast food restaurant employees ($20/hour, effective April 2024) and health care facility employees ($18 to $25/hour, effective October 2024), according to the report.

The duration of temporary disability benefits in California remained fairly stable from 2022 to 2025, a departure from most other study states where duration grew about half a week per year on average. However, fluctuations in the proportion of claims with permanent partial disability or lump-sum settlement payments — and in the average settlement amounts — contributed to year-over-year changes in indemnity costs, WCRI found.

Medical Payments Resume Growth After Years of Stability

Medical payments per claim increased 6% per year on average from 2023 to 2025, breaking from a period of mostly stable trends stretching back to 2010, the report said. Prices paid for professional services in California grew 2% per year from 2022 to 2024, a fairly typical change among study states, according to WCRI’s Medical Price Index.

Growth in payments for evaluation and management services, physical medicine and ambulatory surgery center facility services all contributed, as did higher hospital inpatient payments per episode, WCRI reported.

Benefit Delivery Expenses and Litigation Costs Climb

Benefit delivery expenses per claim grew 9% in 2025, extending a trend that began in 2022 after pandemic-era decreases, the report found. Medical cost containment expenses per claim rose 5% per year from 2022 to 2025, likely reflecting in part the concurrent increase in medical payments, WCRI said.

Litigation-related metrics also trended upward. Defense attorney involvement increased 5 percentage points cumulatively from 2022 to 2025, and the share of claims with medical-legal payments rose 2 points over the same period, according to the report.

In multistate comparisons, California’s total costs per claim for all paid claims — including medical-only claims — were 26% higher than the 18-state median at 36 months of experience. A key driver was that 34% of California claims involved more than seven days of lost time, compared with 25% in the median state, WCRI found.

For claims with more than seven days of lost time specifically, California’s total costs were typical of the study states, reflecting offsetting factors. Indemnity benefits were near the median despite California having the longest temporary disability duration among states with PPD benefit systems. Medical payments per claim were 31% below the median for lost-time claims, driven largely by lower hospital payments. Benefit delivery expenses per claim, however, ranked among the highest of all study states, the report said.
