What Constitutes a Medical Misdiagnosis?

Medical misdiagnosis isn’t merely about identifying a condition incorrectly. It encompasses:

  • Diagnosing the wrong illness entirely. 
  • Missing a diagnosis that should have been identified. 
  • Delays in reaching the correct diagnosis. 
  • Failing to recognize complications from an illness.
  • Ignoring test results or neglecting to order necessary tests.

These mistakes often occur with serious conditions such as cancer, heart disease, infections, or strokes. The sooner these illnesses are treated, the better. A delay or mistake may alter the outcome.

Sometimes, individuals are told they are fine—only to discover later that something serious was overlooked. At other times, an incorrect diagnosis results in treatments that cause more harm than good. Either way, individuals feel betrayed by a system they once trusted.

Real People, Real Consequences

Imagine this: A woman visits the ER with chest pain. The doctor diagnoses it as indigestion and sends her home. The next day, she suffers a heart attack. Or consider a man whose doctor dismisses his chronic cough for months, only for him to discover later it’s late-stage lung cancer. These aren’t just stories—they’re experiences people in Chicago have faced. We have witnessed families losing time, trust, and sometimes the opportunity for treatment.

One client came in after being told for years that her fatigue was “just stress.” Eventually, another doctor discovered she had an autoimmune disorder. The delay resulted in irreversible damage. Another client lost a loved one because a test result was lost in the shuffle, never reaching the right person. These situations occur more often than most people think.

Why Do These Mistakes Occur?

No one wants to believe that a doctor could make a mistake. However, doctors are human, and hospitals are often busy. Mistakes occur for various reasons:

  • Rushed appointments.
  • Poor communication among healthcare staff.
  • Failing to take a patient’s complete history.
  • Over-reliance on a single test or scan.
  • Fatigue or burnout among medical staff.


Some mistakes arise from excessive trust in technology—automated systems, checklists, or diagnostic software. Sometimes, merely failing to listen to the patient may lead to serious harm. We’ve encountered cases where someone clearly described their symptoms, yet the doctor made assumptions or overlooked follow-up steps. It doesn’t require a dramatic error to cause significant harm. All it takes is one missed clue.

Misdiagnosis in Emergency Rooms

WALNER LAW Attorneys

Emergency rooms are fast-paced and often chaotic. Doctors must make decisions rapidly, sometimes without all the necessary information. This pressure may lead to mistakes—especially when symptoms appear mild or do not follow a textbook pattern. We have observed ER misdiagnoses involving strokes, heart attacks, aneurysms, and internal bleeding. In many instances, patients were sent home with a diagnosis such as indigestion, dehydration, or anxiety—only to experience a significant event within hours.

 

In emergency care, time is crucial, and so is listening. When doctors overlook key symptoms or hastily conduct exams, they jeopardize lives. If your ER visit concluded with a serious condition being overlooked, it’s worthwhile to investigate whether something could have been handled differently.

The Role of Diagnostic Tests

Lab tests, X-rays, MRIs, and CT scans help doctors gain a comprehensive understanding. However, they are effective only if they’re actually ordered—and if someone pays attention to the results. We have managed cases where crucial test results were misread, misfiled, or completely overlooked. In other instances, the appropriate test was never ordered in the first place.

When a provider skips a test that could have confirmed a diagnosis or ruled something out without checking, that decision may trigger a chain reaction of errors. Proper use of diagnostic tools often makes the difference between catching an illness early and completely missing it.

Who is Legally Responsible?

When misdiagnosis causes serious harm, someone should be held accountable. Depending on the circumstances, responsibility may lie with:

  • The primary care doctor. 
  • A specialist who provided incorrect advice. 
  • Radiologists or lab technicians who misinterpreted tests. 
  • Hospitals that did not adhere to basic procedures.

 

Some cases involve multiple mistakes. A lab may have flagged an issue, but a nurse forgot to communicate it. A radiologist could have raised a red flag, but the treating physician overlooked it. That’s why our team digs deep. We consult with other doctors, review hospital policies, and analyze every part of the timeline.

You’re not merely seeking someone to blame; you’re searching for answers. That’s what we assist people in discovering.

What You Could Recover in a Misdiagnosis Case

Expertise-Best-Car-Accident-Lawyers-in-Chicago Badge

A medical misdiagnosis disrupts every aspect of a person’s life. Recovery isn’t solely about financial compensation—it involves obtaining support for the repercussions. In these situations, you may be able to seek compensation for:

 

  • Medical bills resulting from incorrect or delayed treatment.
  • Future care that you now require.
  • Lost wages or job opportunities.
  • Pain and alterations to your daily life.

You may have spent months trying to determine what’s wrong. You might have taken unnecessary medication or undergone procedures that exacerbated the situation. In some cases, families lose someone completely because a condition wasn’t diagnosed in time.

Financial recovery aids in the practical aspect. However, it also conveys the message that what occurred was unacceptable. It holds the system accountable, preventing the next person from experiencing the same situation.

Can a Family Member File a Claim?

Yes. If your loved one experienced a misdiagnosis—or died as a result—you may have grounds to file a claim. Family members such as spouses, adult children, and parents of minors typically have legal standing.

In cases involving death, it may be possible to file a wrongful death claim. This may help cover costs such as funeral expenses, lost income, and loss of companionship. These cases do not merely seek financial compensation; they also provide families a means to be heard and achieve closure.

Second Opinions Aren’t Just Smart—They’re Powerful!

A second opinion from a different doctor may confirm if any important details were overlooked. Another provider might assert, “This should have been identified months ago.” Such a statement not only assists you but may also serve as crucial evidence.

Our team assists clients in finding trusted medical specialists who review medical histories and identify errors. That second voice is significantly louder when the first remains silent.

What’s the Difference Between a Mistake and Malpractice?

Not every medical error results in a lawsuit. However, when care falls significantly below what is reasonable and someone suffers, malpractice applies. The law considers:

  • What other doctors would’ve done in the same situation.
  • Whether the mistake directly caused harm.
  • Whether proper care could’ve changed the outcome.

 

We don’t expect doctors to be perfect, but we expect them to act carefully, listen to patients, and follow basic procedures. When these expectations are not met, it’s not just a mistake—it’s a failure that must not be overlooked.

How Walner Law Assists

We understand the feeling of wondering what went wrong. At Walner Law, our lawyers prioritize listening. Every case begins with a conversation. There’s no pressure- just an opportunity to discuss what happened and what happens next. From there, we:

  • Collect medical records and timelines. 
  • Consult healthcare professionals for second opinions. 
  • Examine test results, treatment history, and hospital procedures. 
  • Consider the long-term effects on your life.

We don’t just collect papers; we connect the dots. We ask questions like: When did symptoms start? Who knew what and when? What should have been done differently? Clients often come to us unsure whether what happened was malpractice or bad luck. That’s okay. You don’t have to know everything. That’s our job.

What If the Doctor Disagrees?

Most doctors won’t admit they are wrong. Hospitals often resist. They have legal teams supporting them. However, that doesn’t mean you’re out of options. We examine the facts and consult outside opinions when necessary. The goal isn’t merely to argue. It’s to create a clear picture of what should have happened versus what occurred.

When a hospital or insurance company refuses to settle fairly, it speaks volumes. They had a chance to make things right and chose not to. That’s when we prepare for trial. A courtroom isn’t our first choice, but we’re not afraid to go there if the other side won’t take responsibility.

What Does It Cost to Get Legal Help?

We don’t require payment upfront. If we handle your case, we will only receive payment if you obtain compensation. You never risk paying out of pocket just to have your questions addressed. It also means we only proceed when we believe your case has legitimate grounds.

People sometimes hesitate to call a lawyer because they’re concerned about costs. That’s one thing you don’t need to worry about. We’re here to help, not to add to your burden.

How Long Do You Have to File a Claim?

Illinois law establishes a deadline for medical misdiagnosis lawsuits. This timeframe depends on when the mistake occurred and when it was identified. Generally, individuals have two years from the date they were aware (or should have been aware) of the error. However, the rules may vary in specific situations. Therefore, it is beneficial to consult a lawyer as soon as you suspect something was overlooked or incorrectly handled.

If the affected individual was a minor or the error wasn’t identified immediately, that timeline may change. Even if you believe the deadline has passed, it’s still advisable to reach out. We’ve observed instances where the clock didn’t start ticking until long after the error.

What You Should Do Next

If you believe a diagnosis was overlooked or inaccurate, don’t hesitate. Here are some steps for you to take:

  • Document your recollections regarding your doctor visits and symptoms.
  • Consolidate all medical records, test results, and bills. 
  • Seek a second opinion from a different doctor. 
  • Contact a lawyer experienced in medical cases.

The longer you wait, the harder it becomes to track down what happened. Memories fade, records get lost, and doctors move on to new jobs. Acting sooner makes it easier to build a strong case.

Even if you’re uncertain whether a mistake was made, a consultation provides clarity. By making the call, you’re not committing to anything; you’re simply opening the door to answers.

Every Case Is Different

No two misdiagnosis cases are identical. Some involve months of overlooked signs, while others involve a single significant error. However, in every instance, there’s a real person behind the chart—someone harmed because the system failed.

At Walner Law, we treat every client like family. This approach encompasses straightforward communication, clear steps, and dependable answers. We don’t merely manage paperwork; we invest time in understanding your story, recognizing how the mistake affected your situation, and determining the best course of action.

Some clients seek answers, others desire accountability, and some want both. We’re here for all of it.
