US health insurers reported a difficult second quarter as rising medical costs and greater utilization cut into margins, while workers' compensation carriers remained comparatively shielded.
Analysts said the line continues to act as a stabilizer for commercial insurers, though emerging pressures could test profitability in the months ahead.
According to the National Council on Compensation Insurance (NCCI), the workers' comp weighted medical index rose 2.2% in June. That was below the 2.7% increase in the consumer price index for medical care and the 3% gain in the producer price index for care services. Medical severity, which factors in both price and utilization, increased 6% year over year, with physician services driving much of the change.
"In workers' comp, physician services are definitely the largest share of total services," said Jon Sinclair, NCCI director and actuary, as quoted in a BestWire report. Tying reimbursement rates to Medicare has further helped temper costs, even as private insurance has seen physician payments rise 3% to 3.5%.
That relative stability stands in contrast with health insurers’ second-quarter results. Centene and Molina Healthcare both pointed to elevated behavioral health costs as a leading driver of higher ratios, with executives citing pent-up demand, network expansions and changing demographics. CVS Health also reported weight-loss drug costs accounting for 15% of employer-sponsored pharmacy spend, forcing the company to scale back coverage. Such pressures continue to erode profitability across the health insurance sector.
Workers’ comp profitability has tightened as well, largely due to declining premium volume from falling rates and higher utilization. But AM Best analysts noted it remains one of the strongest contributors to commercial lines earnings. “Long-term declines in the frequency of lost-time claims has tended to mute the impact of medical claims inflation,” said Gordon McLean, senior financial analyst with AM Best.
Looking ahead, industry observers warn that broader healthcare inflation, particularly in pharmaceuticals, could spill into workers’ comp. Potential US drug tariffs, alongside proposals for “most-favored nation” pricing, add further uncertainty.
For now, however, workers’ comp’s structural protections and historically stable claims profile are helping carriers preserve margins at a time when other health-related lines face mounting strain.
