The gap between the lowest- and highest-price states for workers’ compensation medical professional services is stark: prices in Wisconsin were nearly four times those in Massachusetts in 2025, according to Workers Compensation Research Institute’s 2026 Medical Price Index.

The annual study tracks actual prices paid for nonhospital professional services across 36 states, covering approximately 88% of workers’ compensation benefits paid in the United States.

Fee Schedules Contain Costs; States Without Them Pay More

The presence or absence of a workers’ compensation fee schedule remains one of the strongest predictors of price levels and price growth, the WCRI report found. Six study states — Indiana, Iowa, Missouri, New Hampshire, New Jersey, and Wisconsin — had no fee schedule for professional services in 2025. Prices in those states ran 41% to 188% higher than the median of fee schedule states.

The price growth disparity is equally pronounced over time. Looking at states with no major fee schedule changes from 2008 to 2025, the typical cumulative price increase among non-fee schedule states was 43%, compared with 19% among fee schedule states. That translates to an average annual growth rate of 2.1% per year from 2008 to 22025 for non-fee schedule states versus a 1.0% growth rate per year for fee schedule states.

Within the non-fee schedule group, Missouri and Wisconsin stood out, with prices rising 69% and 83%, respectively, over the 18-year period. The report linked their steeper growth, at least in part, to slower expansion of in-network provider participation.

States where more payments flowed through network arrangements — Indiana, Iowa, and New Jersey — saw relatively slower price growth, with the share of payments made to in-network providers for common professional services increasing 14 to 23 percent between 2008 and 2025, compared with 7 to 11 percent in Missouri and Wisconsin.

Price Growth Accelerated After 2021, Then Eased

Across both fee schedule and non-fee schedule states, medical price growth accelerated between 2021 and 2024 before slowing in 2025. The median annual price increase among fee schedule states was 2.4% per year from 2021 to 2024, compared with 0.7% per year from 2013 to 2021. Non-fee schedule states also saw faster growth, at 2.9% per year from 2021 to 2024, up from 2.1% per year in the earlier period.

WCRI attributed the acceleration to two main drivers. First, elevated general inflation during 2021 to 2023 fed through to workers’ compensation prices in states that update their fee schedules using broad price indices rather than medical-specific indices. Second, changes by the Centers for Medicare and Medicaid Services in evaluation and management coding guidelines beginning in 2021 pushed up Medicare relative value unit values, which flowed into workers’ compensation fee schedules in states that base their rates on Medicare RVUs.

By 2025, growth had moderated. The median price increase among fee schedule states was 0.7% — in line with pre-2021 trends — while non-fee schedule states posted a typical increase of 1.7%.

Florida’s Fee Schedule Overhaul Reshuffles State Rankings

Florida’s experience in 2025 illustrates the direct and rapid impact a fee schedule change can have on price levels. Effective January 2025, Florida raised the maximum reimbursement for physician services from 110% of Medicare to 175%, and for surgical procedures from 140% of Medicare to 210%, pursuant to Senate Bill 362.

The result was a 41% jump in overall prices paid for professional services in Florida from 2024 to 2025. Price increases varied by service type, ranging from 26% for pain management injections to 67% for evaluation and management, which is office visits. Major radiology was the exception, with only a 3% increase, consistent with more modest fee schedule adjustments for that category.

Florida’s interstate ranking of prices paid for medical services shifted substantially. In 2024, the state ranked last among all 36 study states for overall professional service prices, with a price index of 67 — or 33% below the 36-state median. By 2025, Florida’s price index rose to 92, placing it 25th out of 36 states and close to the multistate median, the report said.
