California Hospital Workers’ Comp Report Shows Claim Severity on Rise

Article

California workers’ compensation claim severity continues to increase, while claims frequency declines, according a newly released report.

The latest California hospital report benchmarking workers’ comp costs by Milliman and Keenan Healthcare uses data from 35 hospital systems and individual facilities within California to provide more than 3,500 claims for review.

The report offers a glance at factors including claim frequency and severity, impact of workers’ comp reforms, medical and indemnity costs and allocated loss adjustment expense over the past 10 to 12 years. Also included is data on payroll and utilization, age, litigation status and future medical claims.

Trends identified in the report include:

Overall losses per $100 of payroll remained flat over the 10 years ending 2014, with severity of claims on the rise while claim frequency declined.

Estimates of costs per indemnity claim for accidents occurring during 2014 have decreased approximately 10 percent from 2013.

Projected 2015 loss cost per $100 of payroll was at $2.20.

The first notable trend in the report is that severity per paid indemnity claim — indemnity, medical and allocated loss adjustment expense combined — showed an increase of nearly 5.5 percent annually during the period between 2005 through 2014.

The report also notes that the drop off in claim severity that occurred from 2003 to 2004 was due to reform laws enacted during that time. Indemnity claim frequency declined dramatically up until 2008.

The net effect of these two trends combined has been that overall losses per $100 of payroll have been largely consistent across the past 10 years, the report shows.

The decline in claim frequency has been seen both in claims that incur an indemnity payment and in medical-only claims, according to the report. The smallest component, ALAE costs, have increased as a percentage of overall claim costs in recent years.

Workers between the ages of 36 to 55 account for more than half of the paid indemnity claims. The report indicates that the share of overall losses for each age range is less than its share of overall claims for ages 30 and younger, which indicates lesser average severity of indemnity claims for younger workers.

While litigated claims contribute only 20 percent of the total claims with indemnity payment, they account for roughly 54 percent of total incurred losses, the report states.
