Workers’ compensation can seem predictable at first glance. Claim frequency has generally declined, insurance pricing remains competitive, and the market has maintained underwriting profitability for years. Yet the financial impact of individual claims continues to grow.
Medical expenses, wage replacement, and longer recovery periods can quickly turn a workplace injury into a significant liability.
This raises an important question for employers: how much workers’ compensation risk can they comfortably retain when a severe claim occurs?
Excess insurance offers one answer. It adds financial protection above a company’s chosen retention when covered losses exceed expected levels.
For employers managing substantial workers’ compensation exposure, this layer can help protect cash flow.
It can also reduce the financial shock of unusually severe claims without replacing prevention or effective claims management.

Falling Claim Frequency Does Not Eliminate Severe Losses
The workers’ compensation market entered 2026 from a relatively strong position.
According to the Insurance Information Institute’s summary of NCCI’s 2026 findings, the line recorded its 11th consecutive year of net underwriting profitability in 2025.
Yet the numbers also reveal a less comfortable trend. Medical and indemnity claim severity each rose by 4% in 2025.
Lost-time claim frequency fell 2%, but that decline was slower than the long-term annual average of 3.8%.
That difference matters. Fewer claims don't necessarily mean lower financial exposure. A company could experience fewer workplace injuries while facing substantially higher costs from the claims that do occur.
The aging workforce adds another layer. Employees aged 55 and older now make up nearly one-quarter of the labor force.
NCCI Senior Actuary Paul Hendrick notes that demographic changes can directly influence the nature and frequency of workers’ compensation claims. Older workers may have more complex recoveries and higher medical costs.
Claim Costs Can Keep Moving Up
Recent research from the Workers’ Compensation Research Institute highlights growing claim costs. Business Insurance reported that total workers’ compensation claim costs rose by an average of 6% annually from 2022 through 2025 in the median study state.
The increase came from several sources, including medical payments, indemnity benefits, and claim administration expenses. WCRI Vice President Sebastian Negrusa said the growth reflected sustained increases across major claim components.
Medical expenses remain particularly important, as higher healthcare prices contributed to rising medical payments. Longer temporary disability periods also increased indemnity costs.
For employers retaining significant workers’ compensation risk, these trends can gradually alter the assumptions behind their insurance programs.
A retention that once seemed financially manageable may become less suitable as claim costs rise. Regularly reviewing retention levels and excess coverage can help employers respond before unexpected losses create greater financial strain.
Prevention Still Belongs at the Center
Excess insurance shouldn't become an excuse to tolerate preventable workplace injuries. Risk transfer works best when paired with strong safety and claims management practices.
McKinsey has argued that workers’ compensation carriers can play a larger role in healthcare, prevention, and recovery. Its research found that medical services accounted for 60% of workers’ compensation costs at the time of its analysis.
It also estimated that value-based care approaches could generate 5% to 8% savings across books of business. Better medical coordination and faster recovery can therefore reduce claim costs before excess coverage becomes relevant.
Workplace injuries can also create costs beyond the insurance claim. Downtime, lost productivity, replacement-worker training, and post-incident requirements can increase the financial burden.
This makes safety investment and excess insurance complementary parts of a broader workers’ compensation strategy. Preventing injuries reduces the frequency and severity of claims, while excess coverage helps protect the business when significant losses still occur.
FAQ'S
Insurers may consider workforce size, industry, claims history, payroll, job classifications, and workplace safety practices. The employer’s retention level and requested coverage limits can also affect pricing. Companies with severe or frequent losses may face different underwriting conditions than businesses with stronger claims performance.
Businesses should review coverage when they experience major changes in payroll, workforce size, operations or financial capacity. Significant claims can also reveal gaps in existing protection. Annual renewals provide a practical opportunity to reassess whether current limits and retention levels still match the company’s risk profile.
Yes, excess coverage can provide additional protection when workforce changes increase potential workers’ compensation exposure. Seasonal hiring, rapid expansion, or entering higher-risk operations can alter the company’s expected losses. Employers should communicate these changes during underwriting so coverage reflects their current exposure.
Where Excess Insurance Fits
For a self-insured employer, the challenge is deciding where predictable losses end, and unacceptable volatility begins.
This is where excess insurance can become an important risk management tool.
Investopedia describes aggregate excess insurance as protection for self-insured companies when claims exceed a predetermined threshold. Its workers’ compensation example illustrates the concept clearly.
An employer responsible for the first $500,000 in claims could transfer an additional $250,000 to an excess insurer if covered losses reached $750,000.
This structure allows employers to retain losses their balance sheets can reasonably absorb while transferring more severe or unexpected losses. The approach can be particularly valuable as workers’ compensation claim severity continues to rise.
As Prescient National notes, instead of treating every loss as an insurance event, employers can establish a deliberate financial boundary.
Losses below that boundary remain manageable internally, while excess coverage provides protection when claims move beyond the company's expected risk tolerance.
Workers’ Compensation Trends in Numbers
| Workers’ compensation underwriting profitability | 11 consecutive years |
| Annual growth in workers’ compensation claim costs | 6% from 2022–2025 |
| Share of workers’ compensation costs from medical services | 60% |
| Potential savings from value-based care | 5%–8% |
| NCCI’s proposed 2026 loss-cost reduction | 5% |
The right level of excess coverage isn't permanent. Companies grow, payroll changes, workforce age, and operations become more complex. Medical costs and claim severity can shift as well.
These changes should influence how much risk an employer retains. A long-term workers’ compensation strategy should consider loss history, workforce composition, financial capacity, and the ability to absorb severe losses.
The goal isn't simply to buy more insurance. It's to establish a clear boundary between manageable risks and losses that could disrupt the business. Excess insurance can reinforce that boundary when combined with prevention, claims management, and thoughtful financial planning.
