Can Workers' Comp Deny My Surgery in Illinois?

Written by Lily Escorcia, workers' compensation specialist at WIN Injury Network

Quick Answer: Yes, workers' comp insurers in Illinois frequently deny surgery requests. However, you have the right to challenge a denial with an independent medical examination (IME) and legal representation. WIN Injury Network's medical and legal network specializes in overturning surgery denials.

If your Illinois workers' compensation insurer has denied your recommended surgery, you're not alone — and you're not out of options. Insurance companies deny surgeries to save money. It's that simple. But under the Illinois Workers' Compensation Act (820 ILCS 305), you have the right to challenge that decision.

Why Do Workers' Comp Insurers Deny Surgery?

Insurers most commonly deny surgery by claiming: the surgery isn't medically necessary, a less invasive treatment should be tried first, the injury isn't work-related, or the request lacks documentation. None of these denials are automatically final.

What Is an Independent Medical Examination (IME)?

An IME is an evaluation by a physician who has no financial relationship with your employer's insurer. If your surgeon recommends an operation and the company doctor disagrees, an IME provides an independent second opinion that carries significant weight in IWCC proceedings. WIN Injury Network has a network of independent physicians who conduct IMEs for injured workers.

How to Appeal a Surgery Denial in Illinois

You have the right to file a dispute with the Illinois Workers' Compensation Commission (IWCC). The process involves filing an Application for Adjustment of Claim, presenting medical evidence, and in many cases, having a hearing before an arbitrator. An experienced workers' comp attorney dramatically improves your odds of overturning a denial.

Time Limits You Cannot Miss

You have 3 years from the date of injury (or 2 years from your last payment) to file a claim. Don't delay — evidence weakens over time.
