Workers’ Comp Denied My Surgery in Illinois: What to Do Next (Fast)
If workers’ comp denied your surgery in Illinois, don’t assume the denial is final. The insurer often denies expensive procedures to delay payment or push you to use private insurance. The fastest way to fight back is to (1) get the denial in writing, (2) strengthen your surgeon’s medical support, and (3) move the dispute to the Illinois Workers’ Compensation Commission (IWCC)—often with a 19(b) Petition for Immediate Hearing when surgery or benefits are urgently needed. An experienced, aggressive workers’ compensation lawyer can help.
When your doctor recommends surgery and the insurance company says “no,” it can leave you stuck in pain, missing work, and unsure what to do next. In Illinois, surgery denials are common—especially for back, knee, shoulder, hip, and fusion procedures—and many are beatable with the right evidence and pressure.
Why Illinois Workers’ Comp Denies Surgery (and the Real Meaning)
Insurance companies deny surgery because denial is cheap and delay is profitable. Common reasons include:
-
“Not medically necessary” (they claim conservative care should continue)
-
“Not work-related” (IME blames degeneration/arthritis/prior issues)
-
Utilization review / preauthorization “guidelines” (paper denial)
-
They want you to use private insurance (and stop pushing comp)
Key point: In Illinois, an IWCC arbitrator can order the insurer to authorize and pay for reasonable and necessary surgery when the evidence supports it.
What to Do Immediately After a Surgery Denial
1) Get the denial in writing (today)
Ask for the denial letter and any utilization review decision. Keep dates, names, and screenshots.
2) Ask your surgeon for a short “why now” letter (this week)
Have your surgeon address:
-
diagnosis and objective findings (MRI/EMG/exam)
-
what conservative care failed (PT/injections/meds)
-
the exact procedure recommended
-
why delay risks worsening, longer disability, or poorer outcome
- If your surgeon won’t do this, you may have the right to choose another doctor
3) Assume an IME is coming (prepare now)
If the insurer denies surgery, they often schedule an IME to create a defense report. Consistency across records matters.
4) Stop waiting for “reconsideration”
If they denied once, they often stall unless forced into the litigation track.

The Fastest Legal Tool in Illinois: 19(b) Petition for Immediate Hearing
A 19(b) is designed for urgent disputes—like surgery authorization and temporary total disability (TTD) checks. Check out this post with two recent successes under Section 19(b).
A 19(b) hearing can focus on:
-
ordering approval of surgery/treatment
-
restarting stopped checks
-
deciding work-relatedness (causation)
-
forcing the insurer to defend the denial quickly
If your checks are also affected, see the broader denial page here:

Mistakes That Make a Surgery Denial Worse
-
Using private insurance without a strategy (can create reimbursement/causation fights)
-
Waiting months (delay helps insurers)
-
Treating the IME as neutral (it’s often built to deny)
-
Keeping a lawyer who won’t push the case forward
If your current lawyer isn’t fighting, you can switch:

Timeline: What Usually Happens Next
-
Week 1: denial letter / utilization review issued
-
Weeks 1–3: insurer schedules IME or record review
-
Weeks 2–8: if pushed, case can be positioned for a 19(b) hearing
-
After hearing: arbitrator may order surgery authorization and related benefits (case continues)
(Every case differs, but this is the common pattern.)
FAQ
How long does it take workers’ comp to approve surgery in Illinois?
If the insurer agrees, approval can happen within weeks. If they dispute causation or necessity, it may require litigation—often accelerated with a 19(b).
Can workers’ comp deny surgery because of arthritis or a prior condition?
They often try. But if work aggravated the condition and your doctor supports that, surgery can still be ordered.
Do I need a lawyer if my surgery is denied?
Surgery disputes often involve IMEs, medical causation, and formal hearings. If surgery is denied, it’s usually time to talk to a lawyer:
