Medical Misdiagnosis

Zayed Law Offices is proud to serve Chicago and communities across Illinois with experienced personal injury representation, including cases involving misdiagnosis. A misdiagnosis occurs when a physician identifies the wrong condition entirely, leading a patient down a path of unnecessary, ineffective, or even harmful treatment while their actual condition continues untreated. Unlike a failure to diagnose, where a condition is never identified at all, a misdiagnosis actively points a patient and their care team in the wrong direction.

Physicians and hospitals throughout Cook County are expected to carefully evaluate symptoms and consider a reasonable range of possible conditions before settling on a diagnosis. When this process is rushed or incomplete, patients can suffer serious harm, both from the incorrect treatment they receive and from the correct treatment they are denied. Zayed Law Offices works with experienced medical experts to investigate misdiagnosis claims and pursue accountability for injured patients and families.

How Misdiagnosis Happens

Medical Malpractice Lawsuits

Misdiagnosis often results from a combination of rushed evaluations, incomplete testing, and an unwillingness to reconsider an initial impression. Common causes include:

  • Failure to consider a sufficiently broad range of possible diagnoses
  • Anchoring on an initial impression despite conflicting symptoms or test results
  • Failure to order appropriate diagnostic testing to confirm a diagnosis
  • Misreading or misinterpreting imaging studies or lab results
  • Failure to recognize atypical presentations of common conditions
  • Relying on incomplete patient history
  • Failure to consult with or refer to an appropriate specialist
  • Communication breakdowns between multiple treating providers
  • Cognitive bias, such as assuming a common condition when symptoms suggest something more serious

Because many medical conditions share overlapping symptoms, a thorough and open-minded evaluation process is essential to arriving at an accurate diagnosis, particularly when initial test results are inconclusive or symptoms do not fully fit a single condition.

Conditions Frequently Involved in Misdiagnosis Claims

Certain conditions are especially prone to being confused with other, often less serious illnesses. Zayed Law Offices investigates misdiagnosis claims involving:

  • Heart attacks misdiagnosed as anxiety or indigestion
  • Strokes misdiagnosed as migraines or intoxication
  • Cancer misdiagnosed as a benign condition
  • Sepsis misdiagnosed as a minor infection
  • Appendicitis misdiagnosed as general stomach pain
  • Autoimmune disorders misdiagnosed as unrelated conditions
  • Pulmonary embolism misdiagnosed as anxiety or muscle strain
  • Meningitis misdiagnosed as a viral illness
  • Fractures or internal injuries misdiagnosed as soft tissue injuries

Because an incorrect diagnosis often leads to a treatment plan that does nothing to address the real problem, the underlying condition frequently continues to progress while the patient believes they are receiving appropriate care.

Consequences of a Misdiagnosis

The harm caused by a misdiagnosis is often twofold: patients suffer from unnecessary or ineffective treatment while their actual condition goes unaddressed. Zayed Law Offices regularly assists clients and families dealing with:

  • Progression of the true underlying condition to a more advanced or severe stage
  • Complications or side effects from unnecessary treatment or medication
  • Unnecessary procedures or surgeries based on an incorrect diagnosis
  • Permanent organ damage or disability
  • Extended pain, suffering, and emotional distress
  • Additional medical expenses from both incorrect and eventual correct treatment
  • Wrongful death

Because a misdiagnosis often means a patient spent time and resources treating the wrong condition, the eventual correct diagnosis may come only after significant, sometimes irreversible harm has already occurred.

Proving a Misdiagnosis Claim Under Illinois Law

Illinois law requires a patient alleging misdiagnosis to show that a healthcare provider deviated from the accepted standard of care in reaching an incorrect diagnosis, and that this deviation caused harm that would not have occurred with an accurate diagnosis. These cases typically require a detailed review of medical records, testing, and imaging, along with testimony from qualified medical experts to establish both the standard of care and the impact of the misdiagnosis.

Illinois law also requires that a medical malpractice lawsuit be supported by an affidavit of merit from a qualified healthcare professional before the case can proceed. Zayed Law Offices works with experienced medical experts across relevant specialties to closely evaluate the diagnostic process and determine whether a reasonably careful provider would have reached the correct diagnosis.

Illinois’ Statute of Limitations for Misdiagnosis Claims

Illinois generally requires medical malpractice claims to be filed within two years of the date the injury was discovered, or reasonably should have been discovered, but no later than four years from the date of the negligent act itself. Because misdiagnosis cases often involve a gap between the original incorrect diagnosis and the eventual correct one, the discovery rule frequently plays an important role in these cases. Consulting an attorney promptly helps ensure important deadlines are not missed.

Illinois’ Modified Comparative Fault Rule

Illinois follows a modified comparative fault rule, meaning an injured patient can recover compensation as long as they are found less than 51 percent at fault for their own harm. In misdiagnosis cases, defense teams sometimes argue that a patient’s symptoms were genuinely ambiguous or that the patient failed to follow up when symptoms persisted. Thorough documentation of medical visits and communications with providers is essential to countering these defenses.

What to Do If You Suspect a Misdiagnosis

If you or a loved one experienced a misdiagnosis, taking the right steps can help protect both your health and your legal rights.

  • Request complete copies of your medical records, test results, and imaging studies
  • Seek a second medical opinion to confirm an accurate diagnosis
  • Keep a written timeline of your symptoms, diagnoses, and treatments received
  • Document any conversations regarding your original diagnosis and subsequent treatment
  • Avoid signing any statements provided by a hospital or its insurer before speaking with an attorney

The sooner Zayed Law Offices becomes involved, the sooner we can begin reviewing your medical records and consulting with qualified experts to evaluate your claim.

Frequently Asked Questions About Chicago Misdiagnosis Claims

How is misdiagnosis different from a failure to diagnose?

Misdiagnosis means a provider identified the wrong condition, leading to incorrect treatment, while a failure to diagnose means no condition was identified at all. Both can result in serious, preventable harm.

How do I know if my misdiagnosis was caused by negligence?

Determining whether a misdiagnosis resulted from negligence typically requires a detailed review of your medical records by qualified experts, since some conditions can genuinely present in atypical or ambiguous ways.

Why does Illinois require an affidavit of merit for these claims?

Illinois law requires a qualified healthcare professional to confirm a reasonable basis for the malpractice claim before a lawsuit can proceed, helping ensure claims are supported by credible medical review.

How long do I have to file a misdiagnosis claim in Illinois?

Claims generally must be filed within two years of discovering the injury, but no later than four years from the date of the negligent act, with the discovery rule often playing an important role in these cases.

Can I file a claim if a loved one died due to a misdiagnosis?

Yes. Illinois law allows family members to bring a wrongful death claim when a misdiagnosis contributes to a loved one’s death.

What does it cost to hire Zayed Law Offices?

Nothing upfront. Zayed Law Offices handles misdiagnosis cases on a contingency fee basis, meaning there is no cost unless we recover compensation for you.
