Serious Injury Workers’ Compensation Attorneys in Wisconsin

When a workplace injury is severe, the workers’ compensation claim behind it changes character. The medical care runs longer, the impairment is permanent, the dollars at stake climb, and the insurer has far more reason to fight. Serious-injury claims are where the gap between what the law allows and what actually gets paid can be widest — not because the law is stingy, but because the full value of a severe injury has to be built, proven, and pressed. Mays Law Office represents seriously injured workers throughout Wisconsin, and attorney Lisa Pierobon Mays has concentrated on these claims for more than 25 years.

What makes a workers’ comp case “serious”

Wisconsin’s Chapter 102 does not stamp a claim “serious.” In practice, four things do.

The first is permanent disability. Once you reach maximum medical improvement — the point where your condition has stabilized — a physician may assign a permanent impairment. An injury that leaves lasting restrictions, a permanency rating, or the need for a joint replacement is no longer a routine, heal-and-return claim. It carries lifetime consequences, and the law treats it accordingly.

The second is life-changing treatment. Spinal surgery, an amputation, a brain injury, a disc or knee or hip or shoulder replacement, or years of ongoing care all signal a claim whose medical and wage exposure is large.

The third is disputed causation. The more a diagnosis rests on how the injury happened — a single traumatic event versus a pre-existing condition, or a disease that built over years of exposure — the more room an insurer has to contest whether the injury even qualifies. To be compensable in Wisconsin, an injury must arise out of and in the course of employment, and every benefit depends on that threshold being met.

The fourth is benefit exposure. When permanent disability, long treatment, and a possible lifetime of lost earning power stack up, the amount the insurer may ultimately owe grows — and so does its incentive to hold the line. Serious cases are, by definition, the expensive ones.

The benefit stakes in a severe injury

For a badly hurt worker, the difference between the categories of benefits is the difference between a small check and a claim that provides for years.

While you are healing and wholly off work, Temporary Total Disability (TTD) pays two-thirds of your average weekly wage, up to a maximum that changes by injury year. For injuries in 2025 that ceiling is $1,254 per week; for injuries on or after January 1, 2026, it rises to $1,299 per week. (Wisconsin pays nothing for the first three calendar days unless the disability runs past seven.) If you return to lighter or reduced-hour work and earn less, Temporary Partial Disability covers a share of the wage gap instead.

When the injury leaves lasting impairment, Permanent Partial Disability (PPD) applies — and the body part matters. Scheduled injuries to the arms, hands, legs, feet, or your vision and hearing pay a percentage of a set number of statutory weeks tied to your functional loss. Unscheduled injuries to the back, spine, or head are judged on a whole-person or earning-capacity basis, measured against a 1,000-week base. The maximum PPD rate is $446 per week in 2025, rising to $454 per week effective April 1, 2026.

For the most catastrophic injuries — those that permanently end a worker’s ability to earn a living — Permanent Total Disability (PTD) pays at the TTD rate for life. This is the category with the largest lifetime value, and it is precisely the category insurers scrutinize hardest.

If a worker dies from a work injury or occupational disease, eligible dependents may receive death benefits, generally capped at four times the worker’s average annual wage, plus a burial allowance of up to $10,000.

Throughout, reasonable and necessary medical treatment is covered in full, and you are reimbursed for mileage to and from appointments at 51 cents per mile. Every one of these benefits is conditional on a compensable claim — one that arises out of and in the course of employment.

Why serious cases get fought the hardest

The bigger the exposure, the harder the claim tends to be contested. A few dispute patterns recur in severe cases.

The independent medical examination. The insurer has the right to require you to attend an Independent Medical Examination (IME) with a doctor it selects, to assess your treatment, the extent of your disability, and whether you have reached a healing plateau. When that examiner’s opinion differs from your treating doctor’s — a lower impairment rating, a shorter healing period, a different cause — the conflict has to be resolved through the hearing process. In a serious claim, the IME opinion is often the wedge the insurer uses to pay less. You are entitled to keep your own treating physician (subject to the statute’s limits on the number of free choices), and the insurer must reimburse your wages and mileage to attend the exam and give you a copy of the report.

Aggravation and pre-existing disputes. Where a worker had an earlier condition, the insurer may argue the current problem is not work-related at all, or that the job merely revealed something already there. These arguments are common in back, neck, and joint cases. They are dispute patterns, not legal conclusions — how they come out depends on the medical evidence a claim is built on.

Vocational and earning-capacity fights. For an unscheduled permanent injury that keeps a worker from returning to their prior job, the real value often lives in the loss-of-earning-capacity analysis — what the injury did to the ability to earn, weighed against age, education, work history, and restrictions, against that 1,000-week base. This analysis usually enters a claim when the worker’s side builds it, typically with a vocational expert. It does not get raised automatically.

The deadlines that can decide a serious claim

Timing governs Wisconsin workers’ compensation, and in a serious case the clock deserves attention from day one.

You have 30 days to report a work injury to your employer. A late report can be excused only if the employer knew — or reasonably should have known — of the injury, and cannot show it was significantly misled or disadvantaged by the delay.

The deadline to formally pursue a claim depends on the injury. A single-event traumatic injury carries a six-year statute of limitations for injuries occurring on or after March 2, 2016. An occupational disease that develops over time carries twelve years. Each period runs from the date of injury or the last indemnity payment, and every indemnity check resets that clock.

For the most severe injuries, the picture changes again: certain catastrophic injuries carry no filing deadline at all. If you were told an older serious injury is “too late,” that may simply be wrong — it is worth having reviewed.

How Wisconsin hearings work now

If the insurer denies liability, it must tell you in writing why, and advise you of your right to a hearing. You contest a denial by filing a Hearing Application (Form WKC-7), which also pauses the statute of limitations while the case is pending.

Since January 1, 2026, these disputes are handled by the Worker’s Compensation Division at the Department of Workforce Development (DWD), whose administrative law judges hear the cases. The judges run a mediation program to resolve claims early; if no settlement is reached, the claim proceeds to a formal hearing with sworn testimony and cross-examination. A party unhappy with the decision has 21 days to petition the Labor and Industry Review Commission for review, and a LIRC ruling can then be appealed to circuit court.

Hearings are held at seven locations statewide — Madison, Milwaukee, Appleton, Eau Claire, Green Bay, La Crosse, and Wausau — and venue is assigned for the injured worker’s convenience, so a serious claim from anywhere in the state can be heard within reach.

The attorney behind these claims

Lisa Pierobon Mays has devoted her career to Wisconsin injured workers, concentrating exclusively on workers’ compensation for more than 25 years. She was admitted to the Wisconsin bar in 1995 and earned her J.D. from Thomas M. Cooley Law School cum laude. She served on the Wisconsin Association of Workers’ Compensation Attorneys Board of Directors for District 7 from 2001 to 2025 — a credential that reflects a career built inside this practice area. In serious-injury cases, that experience means building the earning-capacity record, answering the insurer’s examiner with your treating doctor’s evidence, and pressing the claim through hearing rather than accepting the insurer’s first number.
