Written by Short answer: Not every surgical mistake qualifies as a “never event,” but that does not mean you have no case. Illinois medical malpractice law covers a broad range of surgical errors that fall short of the dramatic wrong-site or wrong-patient category — wrong technique, failure to recognize intraoperative bleeding, inadequate post-operative monitoring, or premature discharge. Proving these cases is harder than proving a never event, because you must establish what a competent surgeon would have done differently and show that the deviation caused your injury. But they are absolutely winnable. Phillips Law Offices can help you evaluate whether your surgical outcome crosses the legal threshold for a malpractice claim.

I want to be direct about something that often confuses new clients: most surgical malpractice is not dramatic. It is not a surgeon operating on the wrong leg. It is a surgeon who chose a technique that was not appropriate for your anatomy, failed to convert a laparoscopic procedure to open when the situation demanded it, did not recognize that a vessel was bleeding before closing, or cleared you for discharge when your condition required another 24 hours of monitoring. These errors are real, they are compensable, and they are far more common than the cases that make headlines. This guide explains how Illinois law addresses them.
Never-Events vs. Ordinary Surgical Negligence
A surgical never event is a specific category: an error so fundamentally preventable that the National Quality Forum (NQF) has designated it as an event that should never occur in any hospital. Wrong-site surgery, wrong-patient surgery, and retained foreign objects are the classic examples. Illinois law treats these with particular force because the res ipsa loquitur doctrine often applies — the error itself is evidence of negligence without detailed proof of exactly what went wrong.
If you have already read about never events on this site, you know that a separate post addresses that category in detail: Surgical Never Events in Illinois Hospitals. This post covers everything else — the larger, quieter category of surgical negligence that does not rise to the never-event threshold but remains actionable under Illinois law.
| Category | Examples | Proof Difficulty | Typical Damages Range |
|---|---|---|---|
| Never-Event Surgical Error | Wrong-site surgery, retained sponge, wrong-patient procedure | Lower — res ipsa loquitur often applies; error speaks for itself | $500,000 to several million, depending on injury severity |
| Non-Never-Event Surgical Negligence | Wrong technique, failure to convert, inadequate hemostasis, post-op monitoring failure, premature discharge | Higher — requires expert testimony on standard of care and causation; patient was already sick | $250,000 to $2+ million, depending on resulting harm and pre-existing condition |
Common Surgical Errors That Are Not Never-Events
The following categories account for the majority of surgical malpractice claims I handle that do not involve a never event:
- Wrong technique or approach. A surgeon selects a surgical method that is not appropriate for the patient’s specific anatomy, comorbidities, or the condition being treated. A technique that is acceptable for a standard case may be negligent for a complex one.
- Failure to convert from laparoscopic to open surgery. Laparoscopic (“minimally invasive”) procedures carry a recognized standard: when visualization is inadequate, bleeding is not controllable, or anatomy is unclear, a competent surgeon converts to an open procedure. Persisting laparoscopically when conversion is indicated is a documented form of surgical negligence.
- Inadequate hemostasis (failure to control bleeding). Leaving a vessel inadequately sealed, failing to recognize intraoperative bleeding, or closing before hemostasis is confirmed can cause internal hemorrhage that becomes life-threatening after the patient leaves the operating room.
- Post-operative monitoring failures. The period immediately after surgery is high-risk. Nurses and residents working under surgeon supervision must monitor vital signs, drainage, pain levels, and wound condition according to protocol. Failure to recognize deterioration — sepsis, anastomotic leak, pulmonary embolism — and failure to notify the attending surgeon promptly can turn a correctable complication into a catastrophic outcome.
- Premature discharge. Discharging a patient before they are medically stable, to meet a billing target or bed management goal, is negligence when the early discharge proximately causes a readmission injury. This issue is especially common after abdominal and orthopedic procedures.
- Inadequate informed consent. A separate but related claim: if the surgeon failed to disclose a material risk that actually occurred, and you would not have consented had you known, Illinois law permits a claim even if the technical execution of the surgery was flawless.
The Standard of Care in Surgical Cases
Illinois malpractice law measures a surgeon’s conduct against the standard of care: what a reasonably competent surgeon in the same specialty, with similar training and experience, would have done under the same or similar circumstances. This is not perfection. It is not even what the best surgeons do. It is what a competent surgeon does.
Under 735 ILCS 5/2-622, every Illinois malpractice complaint must include an affidavit of merit from a licensed healthcare professional who has reviewed the case and certifies that there is a reasonable basis for the claim. In surgical cases, this is almost always a surgeon in the same specialty — a general surgeon reviewing a general surgery case, an orthopedic surgeon reviewing an orthopedic case.
The standard of care is established through expert testimony at trial. Published clinical guidelines from organizations like the American College of Surgeons, peer-reviewed surgical literature, and hospital policies can all support the expert’s opinion. The defendant surgeon will have their own expert. The jury decides whose account of the standard is more credible.
Proving Causation When Surgery Was Already High-Risk
This is the hardest part of most non-never-event surgical malpractice cases. The patient was already ill before going into the operating room. Bad outcomes in surgery are not uncommon even when everything is done correctly. The surgeon’s defense will argue that the outcome you experienced was a known complication of the procedure, not a result of any error.
Causation is the hardest element in surgical malpractice cases — not because causation is legally ambiguous, but because the patient was already sick before the surgeon touched them. Separating the harm caused by the surgeon’s error from the harm that would have occurred anyway requires a medical expert who can clearly articulate what “but for the deviation” the patient’s trajectory would have looked like. If that narrative is not compelling, the defense wins even when the surgeon made a mistake.
To prove causation in a surgical case, we typically need to establish two things. First, that the surgeon deviated from the standard of care (the “breach”). Second, that this breach more likely than not caused or significantly worsened your injury — not just that it was a contributing factor among many. Illinois uses the “more likely than not” (preponderance of the evidence) standard, which means greater than 50 percent probability.
In cases involving post-operative complications, we often build a causation timeline: what your condition was at discharge, what a proper monitoring protocol would have detected and when, what treatment would have been available at that earlier point, and how that treatment would more likely than not have prevented the injury you sustained. This kind of narrative is painstaking to build but essential to winning.
Consent Issues as Part of a Surgical Malpractice Claim
Illinois recognizes a separate cause of action for lack of informed consent, governed by the doctrine established in Coryell v. Smith and codified in the general negligence framework. A valid informed consent claim requires three elements: the surgeon failed to disclose a material risk of the procedure; the undisclosed risk occurred; and a reasonable patient in your position would not have consented to the procedure had the risk been disclosed.
Informed consent claims are often added alongside a technical negligence claim, particularly when the signed consent form is vague or when the surgeon’s pre-operative discussion was brief. They can also stand alone when the technical execution of the surgery was not negligent but the outcome was a risk that was never mentioned.
Common informed consent issues in surgical cases include failure to disclose the risk of nerve damage, failure to explain the risk of conversion from laparoscopic to open, failure to present non-surgical alternatives for the patient’s specific condition, and failure to disclose the surgeon’s personal complication rate for the procedure when it is materially higher than the published average.
Frequently Asked Questions
If my surgeon made a mistake but I recovered, do I have a case?
Possibly, but damages are a required element of a malpractice claim in Illinois. A surgical error that caused no additional harm — because you recovered fully and the error added no cost, pain, or delay — does not support a lawsuit even if the breach is clear. If, however, the mistake caused additional surgery, a longer hospital stay, pain, scarring, or any other measurable harm, damages exist and the claim may be viable. Call us to walk through the specifics of your situation.
How do I get my surgical records?
Under Illinois law (the Illinois Health Insurance Portability and Accountability Act, 410 ILCS 50/), you have the right to request and receive complete copies of your medical records, including the operative report, anesthesia record, nursing notes, and pathology reports. Hospitals must respond within 30 days. The operative report is the most important document — it is the surgeon’s own contemporaneous account of what occurred and is often where we first identify departures from the standard of care. Request everything, not just the discharge summary.
What expert do I need for a surgical malpractice case?
You need a surgeon in the same specialty as the defendant who can testify that the defendant’s conduct deviated from the standard of care. In complex cases, you may also need a separate causation expert — for example, a specialist in the condition that worsened — to testify about what the outcome would have been with proper treatment. At Phillips Law Offices, we work with a network of credentialed surgical experts in Illinois and nationally to identify the right voices for your case.
Can I sue the hospital as well as the surgeon?
Yes, in most cases. Hospitals are directly liable for their own negligent policies, inadequate staffing, and equipment failures. They are also vicariously liable for the negligence of their employed staff, including nurses and residents. If the surgeon is an independent contractor rather than a hospital employee, the hospital may still be liable under the doctrine of apparent agency if you reasonably believed the surgeon was a hospital employee based on how the relationship was presented. Illinois courts have broadly applied apparent agency in hospital-surgeon cases.
What is informed consent and how does it relate to surgical malpractice?
Informed consent is a patient’s right to understand the material risks and alternatives to any proposed surgical procedure before agreeing to it. In Illinois, a surgeon who performs an operation without adequately disclosing material risks may be liable for a lack-of-informed-consent claim even if the surgery was technically competent. The key question is whether a reasonable patient, fully informed, would have chosen differently. This claim runs alongside — or sometimes independent of — a standard negligence claim.
