Workers’ compensation remains financially strong overall in 2026, but the cost of individual claims is moving in a direction employers, injured workers, insurers, and risk managers should watch closely. The latest National Council on Compensation Insurance (NCCI) State of the Line results show a system with continued underwriting strength, fewer lost-time claims, and rising claim severity at the same time.
NCCI reported that lost-time claim frequency declined by 2% in 2025, while both medical claim severity and indemnity claim severity increased by 4%. In simple terms, there were fewer lost-time claims relative to exposure, but the average cost of those claims continued to rise. That combination matters because lower frequency can support overall system performance even while individual serious claims become more expensive.
For injured workers, “severity” is not a judgment about whether an injury is severe enough to deserve benefits. In workers’ compensation analysis, severity generally refers to the cost associated with claims. Medical severity reflects medical spending, while indemnity severity relates to wage-replacement and other indemnity benefits. Understanding the distinction can make workers’ compensation statistics much easier to interpret.

What the 2026 Workers’ Compensation Data Is Showing
NCCI’s May 2026 State of the Line report described the workers’ compensation system as healthy. Private carriers posted a calendar-year 2025 combined ratio of 91%, marking a twelfth consecutive year of underwriting gains. At the same time, NCCI reported an accident-year 2025 combined ratio of 102%, illustrating why one headline number does not tell the entire story.
The key trend for individual claims is the relationship between frequency and severity. Lost-time claim frequency fell 2% in 2025, while medical and indemnity severity each rose 4%. Claims may therefore be less frequent overall but more costly when they occur.
Frequency Is Falling While Severity Is Increasing
Claim frequency measures how often claims occur relative to an exposure base, while severity focuses on how costly claims become. These two measures can move in opposite directions. A workplace can experience fewer injuries while still facing higher average costs for the injuries that do occur.
Rising severity does not necessarily mean the entire system is deteriorating. NCCI’s 2026 results show strong overall performance while also identifying cost pressures. For injured workers, those pressures help explain why medical care, wage replacement, recovery time, and return-to-work outcomes remain central to claim value.
Medical Severity Increased 4% in 2025
Medical severity increased by 4% in NCCI’s 2025 results. Severity can reflect several moving parts, including prices for medical services, the amount and type of treatment used, the nature of injuries, worker demographics, comorbidities, and how long care continues.
NCCI emphasized in its 2026 research that medical severity is not a single concept. The organization points to the combined influence of the injury itself, the worker’s medical conditions, and treatment over time. It has also found that age, wage, health status, and where treatment begins can affect utilization and claim outcomes.
That means a rise in medical severity should not automatically be interpreted as a simple increase in doctors’ prices. Medical inflation matters, but utilization can matter too. A claim involving more visits, procedures, therapy, diagnostics, prescriptions, or a longer treatment period can cost more even when the price of each individual service changes only modestly.
Indemnity Severity Also Increased 4%
Indemnity benefits generally address the income side of a workers’ compensation claim. Depending on the state and the claim, they may include temporary disability payments, permanent disability benefits, or other wage-related benefits. NCCI reported that indemnity severity also increased by 4% in 2025.
Wage growth can contribute to this trend because many wage-replacement benefits are tied to an injured worker’s earnings, subject to state-specific formulas, minimums, and maximums. A worker with higher pre-injury wages can therefore generate higher indemnity costs than a lower-wage worker with an otherwise similar disability period, although the actual amount depends heavily on state law.
Claim duration matters too. If an injured employee remains off work longer, wage-replacement costs can grow. Return-to-work planning, medical recovery, and suitable job accommodations can therefore affect claim costs.
Medical Utilization Is Becoming an Important Part of the Cost Story
One of the more interesting 2026 developments is NCCI’s research into the relationship between wages and medical utilization. In August 2026, NCCI reported that for lost-time claims, medical utilization grows as injured-worker wages rise, and that the correlation persists across age groups, jurisdictions, industry groups, and even class codes within industries.
This does not mean wages cause medical treatment. Rather, wage levels can be associated with claim characteristics that affect utilization and final costs, showing why severity cannot be explained by medical inflation alone.
Higher Medical Costs Are Not Just a Price-Inflation Story
NCCI’s July 2026 medical inflation work tracks a workers’ compensation-weighted medical price index designed to reflect the mix of medical spending seen in workers’ compensation claims. At the same time, NCCI’s medical-severity research emphasizes utilization, demographics, and claim complexity. Together, those findings support a more complete view: price is one driver, but how much care is used and what kind of care is provided can be just as important.
For an injured worker, the practical lesson is to focus on medically appropriate treatment and accurate documentation rather than trying to interpret a claim through national averages. For employers and claims professionals, early access to appropriate care, return-to-work coordination, and careful monitoring of treatment patterns may help control unnecessary claim duration without interfering with necessary medical care.
What Rising Claim Severity Means for Workers and Employers
Rising severity is most useful as a signal, not a prediction of what any particular claim will be worth. Workers’ compensation benefits are governed primarily by state law, and the value of a claim can depend on wages, disability duration, medical treatment, impairment, benefit limits, disputed issues, and whether the worker can return to the same job.
For injured workers, documentation remains essential. Keep work-status reports, medical records, wage statements, benefit notices, reimbursable mileage records, and written communications about job restrictions. Missing records can create avoidable disputes over wages, treatment, or return-to-work status.
Employers should focus on both prevention and claim duration. Falling frequency is positive, but a small number of complex claims can still have a meaningful impact. Prompt reporting, appropriate medical care, suitable transitional work, and accurate wage information can influence how a claim develops.
State Rules Can Change the Cost of the Same Type of Injury
Workers’ compensation is not one uniform national benefit program. Each state sets its own rules for medical fee schedules, wage-replacement formulas, benefit caps, disability ratings, provider networks, dispute procedures, and other claim components. Two workers with similar injuries and similar wages can therefore have different benefit outcomes in different states.
This state variation also matters when reading national cost data. NCCI’s August 2026 review of Medicare fee schedules noted that the effect of federal reimbursement changes on workers’ compensation medical costs varies by state depending on which medical services are covered by state fee schedules, how those schedules incorporate federal rules, and the state’s distribution of medical spending.
2026 Medicare Changes Are Not Expected to Be a Major Overall Cost Driver
NCCI reported that 2026 Medicare fee-schedule changes are not expected to create significant upward pressure on overall workers’ compensation medical costs, although the impact differs by state. Among the changes NCCI highlighted were rebalanced physician relative value units, moderate facility base-rate increases, and a 2% update factor for certain durable medical equipment, prosthetics, orthotics, and supplies.
That finding is another reason not to attribute rising workers’ compensation severity to one single cause. Medical prices, utilization, wages, claimant demographics, injury mix, treatment setting, state benefit rules, and claim duration can all influence costs.

Bottom line: workers’ compensation in 2026 presents a mixed but understandable picture. The system remains financially strong, lost-time claim frequency continues to decline, and yet the average cost of claims is increasing. Medical and indemnity severity both rose 4% in 2025, making claim complexity, treatment utilization, wages, recovery time, and state-specific benefit rules increasingly important to understand.
