Workers Comp Claim Denied in Illinois — What to Do Next

Why Do Insurance Companies Deny Workers’ Comp Claims?

Insurance companies deny claims for many reasons — some legitimate, most not. The most common denial reasons we see in Illinois:

• The injury was not reported in time. Illinois requires you to notify your employer within 45 days of the injury. If this deadline passed, the insurer may use it to deny your claim — but there are exceptions, and many denials on this basis can still be challenged.
• The employer disputes the employment relationship. This is especially common in construction and the trades, where employers label workers as independent contractors to avoid liability. We have won cases where employers completely denied any employment relationship.
• The insurer claims the injury is pre-existing. Insurance adjusters frequently argue that your injury existed before the workplace accident. This does not disqualify you — Illinois law covers conditions that work aggravated, accelerated, or combined with.
• The injury is claimed to be non-work-related. The insurer says the injury didn’t happen at work, or wasn’t caused by your job. This is often disputed in cases involving repetitive trauma, occupational disease, or injuries that occurred in ambiguous circumstances.
• Medical treatment is disputed or delayed. Sometimes the claim is accepted but medical treatment is denied, delayed, or the insurer refuses to authorize surgery or specialist care.
• The settlement offer is too low. Technically not a denial, but many injured workers receive offers so far below fair value that the practical effect is the same.

What to Do Immediately After a Denial

1. Get the denial in writing. Ask for a written explanation of why your claim was denied. This is your starting point for the appeal.
2. Do not sign anything from the insurer. A denial letter may be accompanied by a release or settlement offer. Do not sign before speaking with an attorney.
3. Gather your records. Collect everything: the accident report, your medical records, any communications with your employer or their insurance company, and your denial letter.
4. Contact a workers’ compensation attorney immediately. Appeals in Illinois have deadlines. The sooner you get an attorney involved, the more options you have.
5. File a Petition for Review or Application for Adjustment of Claim. Our attorneys handle this filing with the Illinois Workers’ Compensation Commission on your behalf.

How the Illinois Workers’ Compensation Appeal Process Works

In Illinois, disputed workers’ compensation claims go before the Illinois Workers’ Compensation Commission (IWCC). Here is how the process works:

• Arbitration. Your case is first heard by an IWCC arbitrator — an administrative law judge who reviews the evidence and makes a decision. This is where the majority of contested claims are resolved.
• Review by the Commission. If either side disagrees with the arbitrator’s decision, they can request a review by a full panel of IWCC commissioners.
• Circuit Court review. If the Commission’s decision is disputed, either party can seek review in the Circuit Court of Cook County or the relevant county.
• Appellate Court. Further appeals can proceed to the Illinois Appellate Court and, in rare cases, the Illinois Supreme Court.

The process sounds complicated — and it is. But our attorneys have navigated it hundreds of times. We know the arbitrators, we know the process, and we know how to build the strongest possible case for your hearing.

Frequently Asked Questions — Workers Comp Denial in Illinois

Q: Is there a deadline to appeal a denied workers’ comp claim in Illinois?

Yes, and it is critical. Once you receive a denial, you must file an Application for Adjustment of Claim with the Illinois Workers’ Compensation Commission within 3 years of the date of injury. However, the sooner you file, the better — delays can complicate your case. Do not wait until the deadline is close. Call us as soon as your claim is denied.

Q: My employer denied workers’ comp because they say I am an independent contractor. What can I do?

Challenge it. Illinois has some of the strictest anti-misclassification rules in the country. Many workers labeled as independent contractors are actually statutory employees under Illinois law and are fully entitled to workers’ comp. We have taken cases to arbitration and won on this exact issue — including cases where the employer denied any employment relationship at all. Do not accept a contractor classification without a legal review.

Q: The insurer accepted my claim but is refusing to pay for my surgery. What are my options?

This is a treatment denial, and it is very common. You have the right to dispute a treatment denial through the IWCC. An arbitrator can order the insurer to authorize and pay for the treatment if it is medically necessary. Our attorneys file for emergency relief in cases where delayed treatment is causing serious harm. Call us immediately if your medical care is being denied or delayed.

Q: I already signed a settlement. Can I reopen my case if I find out my injury is worse than expected?

In most cases, no. Illinois workers’ comp settlements are generally final. This is exactly why you should not sign any settlement agreement without first consulting an attorney. The only exception is if you can prove fraud or mutual mistake in the settlement agreement — an extremely difficult standard to meet. If you have not yet signed, call us before you do.
