You handed your health to someone in a white coat, and something went wrong. Now you’re lying awake asking whether it was bad luck or a real mistake.
Medical malpractice happens when a doctor, nurse, or hospital gives care that falls below the accepted standard and that failure hurts you. In Illinois you generally have two years from when you knew, or should have known, that an injury came from malpractice, under Illinois Compiled Statutes (ILCS) Chapter 735, Section 5/13-212(a). Further, no adult claim can be filed past four years after the act or omission, no matter when you found out.
Willens & Baez Personal Injury Lawyers, PC handles medical malpractice cases for patients and families across Chicago and Cook County. Matthew Willens and David A. Baez have recovered millions for clients hurt by preventable medical errors, including a $12,250,000 birth injury settlement and a $7,000,000 surgical error settlement. You pay us nothing unless we recover money for you.

Key Terms in an Illinois Medical Malpractice Case
Malpractice cases come with their own vocabulary, and you’ll hear it from day one. This table covers the words that actually change what happens to your claim.
| Term | What It Means for Your Case |
|---|---|
| Standard of care | What a reasonably careful provider in the same field would have done in your situation. Your case is measured against this, not against a perfect outcome. |
| Breach | The moment the provider fell below that standard. Examples are missing a test result, ignoring a symptom, or operating on the wrong site. |
| Causation | Proof that the breach is what hurt you. Illinois requires this link, and it is usually the hardest part to establish. |
| Discovery rule | The two year clock starts when you knew or reasonably should have known your injury came from malpractice, not always the date of medical service (735 ILCS 5/13-212[a]). |
| Statute of repose | A hard outer time limit for filing a lawsuit. For adults, no malpractice suit can be filed past four years after the act or omission, even if you never knew the harm in time (735 ILCS 5/13-212[a]). |
| Certificate of merit | A sworn affidavit plus a written report from a qualified health professional saying your claim is reasonable and meritorious. Required by 735 ILCS 5/2-622. |
| Comparative fault | If a jury finds you more than 50% responsible, you may receive no compensation. At 50% or less, your award is reduced by your share of fault (735 ILCS 5/2-1116). |
How Much Does a Medical Malpractice Lawyer Cost in Chicago?
Nothing up front. Willens & Baez takes medical malpractice cases on contingency, which means our fee comes out of the recovery and only if there is one.
Illinois puts a hard ceiling on that fee. Under 735 ILCS 5/2-1114(a), the total contingent fee in a medical malpractice case cannot exceed 33 1/3% of all sums recovered. That cap is set by statute, so no firm in Chicago can charge more.
Case costs are separate from the fee, and in a malpractice case they are the real expense. These claims run on expert testimony. Before a complaint can even be filed, a qualified health professional has to review the full chart and write the report required by 735 ILCS 5/2-622. Then each specialty involved in your care usually needs its own retained expert.
Add medical record retrieval, court reporters, deposition transcripts, and exhibits. On the court side, the Clerk of the Circuit Court of Cook County’s published Law Division fee schedule lists a $388 filing fee to open a medical malpractice case, plus a $250 appearance fee for each defendant who appears.
We advance those costs. You don’t write checks while your case is pending, and you don’t owe a fee if we don’t recover. Before you sign anything with any firm, ask two questions in writing: who pays the case costs, and what happens to them if the case is lost?
We explain how our fees work and what contingency means for you in more detail on the blog.
How Long Do You Have To File a Medical Malpractice Claim in Illinois?
Two years from the day you knew that your injury came from malpractice (735 ILCS 5/13-212[a]). The “discovery rule” allows the two-year clock to start running not on the date of malpractice but on the date you reasonably should have known that it caused you harm. But there’s a second clock running called the statute of repose, which says adult victims cannot sue more than four years after the malpractice, no matter when they found out. The deadlines shift for children and for people under a legal disability.
Say it’s been three years since the surgery, and you only learned last month that the second operation was needed because of a mistake in the first. The discovery rule may give you time. The statute of repose may not.
| Your Situation | Deadline to File | Illinois Statute |
|---|---|---|
| Adult injured by malpractice | 2 years from the date you discovered or should have discovered the injury | 735 ILCS 5/13-212(a) |
| Adult, outer limit | 4 years from the act or omission, regardless of when you discovered it | 735 ILCS 5/13-212(a) |
| Child under 18 when the malpractice happened | 8 years from the act or omission, and never past the child’s 22nd birthday | 735 ILCS 5/13-212(b) |
| Legal disability at the time the claim accrued | The clock does not begin until the disability ends. | 735 ILCS 5/13-212(c) |
| Care at a county or other local public hospital | Same 2 year and 4 year limits, but under a separate statute | 745 ILCS 10/8-101(b) |
| Death caused by malpractice | Generally 2 years from the date of death | 740 ILCS 180/2(d) |
These rules interact, and the interaction is where people get hurt. A claim can be inside the two year window and still be barred by the four year repose. Cases involving fraudulent concealment follow different rules under 735 ILCS 5/13-215. Care at a state-run hospital can route through the Illinois Court of Claims with its own notice rules.
We explain how the malpractice filing deadline works in more detail, but the safest move is to have someone look at your dates now. A Chicago medical malpractice lawyer can tell you in one phone call whether the clock is a problem.
How Do I Know if I Have a Medical Malpractice Case?
You have a potential case when the medical provider’s care fell below the standard, that failure caused a real injury, and the deadline has not passed. Here is how that breaks down into things you can actually check.
- Something went wrong that was not explained as a risk beforehand. A complication you were warned about, watched for, and treated promptly is usually not malpractice. One that was missed for days because nobody read the chart usually is.
- You have a lasting injury, a new condition, or a lost family member. Malpractice cases need real damages. A close call with no lasting harm is rarely worth the cost of building the case.
- The timeline still fits. Count from the date you first suspected the care was the problem. If that was less than two years ago, and the treatment itself was less than four years ago, you are likely inside the window.
- You can name the providers and facilities. Even a rough list of who treated you and where is enough for us to start requesting records.
- A physician in the same field would say the standard was missed. You are not expected to know this. It is what the records review and the certificate of merit process are for.
If the first four are true, call us at Willens & Baez. We investigate the fifth. If you want to think it through first, we wrote a guide on what to do if you think your doctor committed malpractice.
What Counts as Medical Malpractice in Illinois?
An emergency room sends you home while a heart attack is still in progress. Illinois law calls that malpractice only when four things line up: duty, breach, causation, and damages. All four, every time.
- Duty. The provider took you on as their patient, so they owed you a professional standard of care.
- Breach. What they did, or failed to do (“omission”), fell below what a reasonably careful provider would have done.
- Causation. That failure is what caused your injury, not your underlying illness.
- Damages. You lost something real: money, health, function, or a family member.
Causation is where most cases live or die. A sick patient who gets worse is not automatically a malpractice case, and hospital lawyers know it. Proving the link takes medical records, a treating timeline, and a qualified expert who will say out loud that the standard was missed.
If you want a closer look at the first element, we break down what duty of care means for your medical malpractice case.
If you already know something feels wrong, it costs you nothing to trust that instinct enough to ask our lawyers at Willens & Baez.
Bad Outcome or Malpractice? How To Tell the Difference
Not every bad result is someone’s fault. Medicine has real limits, and some conditions get worse no matter how carefully they’re treated. The question is not whether the outcome was bad. It’s whether the care was.
A known complication that was explained to you beforehand, watched for, and treated promptly usually is not malpractice. A complication that was missed for three days because nobody read the chart usually is. Same complication, different care.
Some patterns show up again and again in the cases we take. A test result that sat unread. A symptom that was written off. A patient who kept calling and kept getting told to wait. A shift change where nobody passed along the warning signs.
You will not be able to sort this out from a discharge summary, and you shouldn’t have to. That’s what the records review is for.
What Illinois Requires Before You Can File
You can’t just walk into the Daley Center and file a malpractice complaint. Under 735 ILCS 5/2-622, Illinois courts require a certificate of merit before the case can go forward.
Your attorney has to file a sworn affidavit stating that a qualified health professional reviewed the records and concluded there is a meritorious and reasonable cause for the case. A written report from that professional gets attached. Under the statute, the reviewing professional must be knowledgeable in the issues, must have practiced or taught in the same health care field within the last six years, and must meet the standards for expert witnesses set by 735 ILCS 5/8-2501.
A separate certificate and report is required for each defendant named in the complaint. If the deadline is closing in and there isn’t time to complete the review, the statute allows the affidavit to be filed first and the certificate within 90 days. Skip it entirely and the case is subject to dismissal under Section 2-619.
This is the practical reason malpractice cases start slowly. The expert review has to happen before the lawsuit exists, and that review takes real time and real money. Willens & Baez advances those costs, so the wait doesn’t come out of your pocket.
Types of Medical Malpractice Cases We Handle in Chicago and Cook County
Medical malpractice covers far more than surgery gone wrong. Willens & Baez handles claims across the full range of hospital and clinic errors:
- Birth injuries, including cerebral palsy, shoulder dystocia, and brachial plexus injuries
- Surgical errors, retained instruments, and wrong-site procedures
- Misdiagnosis and delayed diagnosis of cancer, stroke, sepsis, and heart attack
- Medication and dosing errors, including anesthesia mistakes
- Failure to order tests or to act on abnormal results
- Emergency room errors during triage and discharge
- Inadequate monitoring after surgery or during labor
- Hospital negligence in staffing, hygiene, and equipment maintenance
- Nursing home and long-term care neglect
- Deaths caused by preventable medical error.
Our birth injury cases often begin with a fetal monitor strip nobody acted on. Our surgical error cases often begin with pain that never made sense to the surgeon. Our misdiagnosis claims and delayed diagnosis claims usually start with a patient who was told, more than once, that nothing was wrong. When the harm happened in a care facility, our nursing home neglect team takes it from there.
If your situation isn’t on this list, call anyway. The label matters much less than the medical records.
How Long Does a Medical Malpractice Case Take in Chicago?
Most take one to three years, and the ones with several defendants or a trial date can run longer. Malpractice cases run longer than ordinary injury cases. The expert work happens before filing, the defense is well funded, and hospitals rarely settle early. Knowing the stages makes the wait easier to sit with.
| Stage | What Happens | What Can Slow It Down |
|---|---|---|
| Free consultation | You tell us what happened and we identify the providers, dates, and facilities involved. | Nothing. This step is quick. |
| Records collection | We request the complete chart from every hospital, clinic, and provider who treated you. | Hospitals that release records slowly or in pieces |
| Expert review | A qualified health professional reviews the chart and prepares the written report required by 735 ILCS 5/2-622. | Finding the right specialty and getting on that expert’s calendar |
| Filing the complaint | The complaint, the affidavit, and a certificate for each defendant are filed in the Law Division of the Circuit Court of Cook County at the Daley Center. | Multiple defendants, since each one needs a separate certificate and report |
| Written discovery | Both sides exchange documents, policies, staffing records, and interrogatory answers. | Defense objections and motions over what has to be produced |
| Depositions | Treating providers, hospital staff, and retained experts testify under oath. | Coordinating physician schedules across several practices |
| Settlement talks or mediation | The insurer evaluates exposure and negotiations begin in earnest. | A carrier that would rather test the case in front of a jury |
| Trial | A Cook County jury decides liability and damages. | Court calendar backlogs and pretrial motions. |
Most cases resolve before a jury is ever picked. The ones that settle well are the ones that were built as if they were going to trial from the first records request.
One rule works in your favor here. Since July 1, 2021, plaintiffs in Illinois personal injury and wrongful death cases recover prejudgment interest at 6% per year on compensatory damages, starting from the date the case is filed and running up to five years (735 ILCS 5/2-1303[c]). That gives hospitals a real reason not to stall.
You will not be doing this alone or in the dark. Our team keeps you current at every stage, because the not-knowing is often worse than the waiting.
What Is a Medical Malpractice Claim Worth in Illinois?
There is no cap or limit. The Illinois Supreme Court struck down the state’s limit on non-economic damages in Lebron v. Gottlieb Memorial Hospital in 2010, holding that it violated the separation of powers clause of the Illinois Constitution. No ceiling has replaced it since.
What your case is worth depends on what the error cost you, and no honest lawyer can put a number on it from an injury type alone. Illinois malpractice damages generally include:
- Past and future medical bills, including surgery, therapy, and long-term care
- Lost wages and lost earning capacity if you can’t return to the same work
- Pain and suffering
- Disfigurement and disability
- Loss of a normal life
- Loss of consortium for a spouse
- Funeral and burial costs in a wrongful death case.
Two limits matter. Punitive damages are not available in healing art malpractice cases in Illinois under 735 ILCS 5/2-1115. And if a jury assigns you more than 50% of the fault, you recover nothing at all under 735 ILCS 5/2-1116.
When a preventable error kills a patient, the family brings a wrongful death claim on behalf of the surviving spouse and next of kin under 740 ILCS 180. Nothing about money fixes that loss. It does pay the bills the death left behind, and it puts the failure on the record.
Defenses Doctors and Hospitals Use in Illinois
Hospitals do not roll over. Their insurers hire experienced defense counsel the moment a claim surfaces, and the arguments follow a familiar pattern:
- The standard of care was met. The most common defense is simply that the provider did what a reasonably careful physician would have done. Your outcome was bad, they’ll say, but the care was sound. This turns into a battle between experts, which is why the strength of your expert matters as much as the facts.
- A respectable minority supports the treatment. Medicine often has more than one accepted approach. If a respected group of physicians would have chosen the same course, the defense will argue the provider was within the standard even if most doctors would have done something else.
- You waited too long. Expect the defense to test your dates against 735 ILCS 5/13-212. They will argue you knew, or should have known, about the injury earlier than you claim. Written notes, complaints to the provider, and second opinions all become evidence of when the clock started.
- You share the blame. Missed follow-up appointments, unfilled prescriptions, and incomplete medical histories all get used against you. Under 735 ILCS 5/2-1116, contributory fault of more than 50% bars recovery entirely, and anything less reduces your award in proportion. This is why an honest first conversation with your lawyer matters more than a flattering one.
- It was a known complication. Consent forms list risks for a reason, and the defense will point to yours. Signing a consent form does not waive your right to competent care. It acknowledges a risk existed, not that any level of care was acceptable.
How Do I Choose a Medical Malpractice Lawyer in Chicago?
Ask every firm you talk to, including us at Willens & Baez, the same five questions and compare the answers:
- How many medical malpractice cases have you taken to verdict? Malpractice defense firms know which plaintiff’s lawyers settle cheap. A firm with trial results gets better offers.
- Who will review my records, and when? The answer should name a physician in the right specialty and a timeline. Vague answers mean the case sits.
- Who pays the expert costs, and what happens to them if we lose? Get this in writing. Expert fees in a malpractice case can run well into five figures before trial.
- Have you handled my kind of case? A birth injury, a missed cancer diagnosis, and a surgical error need different experts and different case strategies.
- Who will actually be my lawyer? You should know the name of the attorney handling your file, not just the one on the billboard.

What To Do If You Think You Were Hurt by Medical Malpractice
- Get the care you need now. See a different provider if you’ve lost trust in the first one. Your health comes before the claim.
- Write down what you remember while it’s fresh. Include dates, names, what you were told, and when symptoms started. Memory fades faster than you’d expect.
- Request your records, or let us do it. You have a right to your chart. We request it from every provider once you retain us.
- Keep every bill, letter, and discharge paper. Don’t throw anything away, even the ones that seem routine.
- Do not sign anything from the hospital or its insurer. Releases and “patient relations” agreements can limit your claim.
- Do not post about it online. Defense lawyers read social media.
- Call a Chicago medical malpractice lawyer before the two year clock gets close. The expert review takes time, and the deadline does not wait for it.
