When Does Misdiagnosis Qualify as Medical Malpractice?

Dаmаgеѕ Rеlаtеd tо the Injury

Medical misdiagnosis happens more often than people realize. Studies show that 25 million around the world are misdiagnosed each year. While not every incorrect diagnosis amounts to malpractice, misdiagnoses that result from negligence and cause harm may become malpractice cases.

Elements Necessary for a Misdiagnosis Claim

To bring a viable medical malpractice lawsuit for misdiagnosis, four key legal elements must be proven:

1. Doctor-Patient Relationship

There must be a doctor-patient relationship that establishes a duty of care by the physician. This means you were or should have been under that doctor’s care when the alleged misdiagnosis occurred.

2. Negligence

The physician must have acted negligently, deviating from the accepted standard of care that should have been provided. Simply being wrong about a diagnosis does not always equal negligence.

3. Resulting Harm

It must be shown that the misdiagnosis directly caused harm, such as physical injury, disability, lost wages, pain and suffering, or progression of the condition.

4. Ability to Claim Damages

You must have incurred quantifiable monetary losses that can legally be claimed as compensation.

“To constitute medical malpractice, there must be a duty owed by the physician to the patient, a breach of that duty by the physician, and an injury proximately caused by the physician’s breach.” – American Medical Association

Types of Negligent Misdiagnoses

Misdiagnoses may take several forms, depending on the error made:

  • Wrong diagnosis – an incorrect condition is diagnosed
  • Missed diagnosis – the doctor fails to detect the presence of a condition
  • Delayed diagnosis – diagnosis takes longer than medically reasonable
  • Failure to diagnose complications – missing complications related to an existing condition

Seemingly simple oversights can have catastrophic outcomes for the patient. Demonstrating exactly how the physician was negligent is key.

Most Commonly Misdiagnosed Conditions

Certain conditions are more prone to diagnostic errors. The most misdiagnosed include:

  • Cancer
  • Heart attacks
  • Strokes
  • Appendicitis
  • Diabetes

Vague or atypical symptoms often complicate these diagnoses. But failing to diagnose these conditions promptly leads to dire consequences.

“Not all diagnostic errors are malpractice. Some errors are unavoidable, even with the best medical care.” – New England Journal of Medicine

Reasons Behind Diagnostic Errors

Several factors cause physicians to misdiagnose conditions and commit errors leading to potential malpractice:

  • Communication breakdowns – Issues conveying or gathering patient information
  • Faulty medical tests – Inaccurate or misinterpreted test results
  • Atypical symptom presentation – Vague/unexpected symptoms complicate diagnosis
  • Inherent diagnostic uncertainty – Some conditions are inherently harder to diagnose

Pinpointing exactly how these or other factors resulted in misdiagnosis builds a negligence claim.

Consequences of Misdiagnoses

Misdiagnoses lead to grave outcomes, including:

  • Progression of untreated, worsening medical conditions
  • Complications from unnecessary treatments and medication side effects
  • Emotional distress – anxiety, loss of trust in doctors
  • Disability when worsening illness causes loss of faculties
  • Wrongful death

The more severe the repercussions, the more clearly it demonstrates the harm done. Economic and non-economic damages can be claimed based on these consequences.

Steps to Take After a Suspected Misdiagnosis

If you discover you’ve received the wrong diagnosis, take action promptly:

  • Get copies of all medical records – These prove what diagnoses you received
  • Consult a medical malpractice attorney – Legal guidance is key in these cases
  • Calculate and document all losses – Account for medical costs, lost income, pain and suffering

Time is of the essence, as statutes of limitations restrict filing time windows. An experienced attorney assists with these steps.

“If you believe you have been misdiagnosed and suffered harm, consult with an attorney experienced in medical malpractice law.” – American Bar Association

Building a Strong Misdiagnosis Malpractice Case

Crafting a compelling case requires legal skill and medical evidence. Strategies include:

  • Using medical experts to establish negligence – Expert testimony speaks to proper standards of diagnosis and if they were breached
  • Pinpointing where the error occurred – Identifying the exact action or omission that caused the misdiagnosis
  • Determining who is liable – Doctor directly responsible? Testing lab? Equipment manufacturer that caused faulty results?

Successfully proving negligence and causation this way can make or break the case.

Recovering Damages in Misdiagnosis Lawsuits

If negligence is established in misdiagnosis, damages that may be claimed include:

Economic Damages

  • Medical costs
  • Lost income
  • Loss of future earnings

Non-Economic Damages

  • Physical pain/mental anguish
  • Loss of companionship
  • Loss of enjoyment of life

Punitive Damages

  • Awarded if negligence is exceptionally reckless or severe.

Document all losses and use legal counsel to maximize recoveries.

Statute of Limitations Issues

Statutes of limitations dictate strict statewide deadlines for filing medical malpractice claims. These range from 1 year (Kentucky) to 6 years (Maine). Filing past the cutoff can nullify the claim. Acting promptly is essential.

“Never ignore a misdiagnosis, especially if you believe it has caused you harm. Seek medical attention and legal advice promptly.” – American Patient Advocacy Association


Medical misdiagnoses that breach the standard of care and result in preventable patient harm cross into negligence and malpractice territory. Suffering parties enduring losses have legal grounds to pursue action.

With stringent filing limitations, complicated legal nuances to navigate, and evidence from medical experts required, pursuing misdiagnosis cases necessitates skilled guidance. An attorney well-versed in medical malpractice law is indispensable for mounting credible challenges. Especially when one’s health, livelihood and justice hang in the balance.

Key Takeaways

  • Not all diagnostic mistakes qualify as malpractice
  • Negligence that directly causes patient harm is key
  • Immediately get medical records and consult legal counsel
  • Medical experts bolster proof of negligence
  • Economic and non-economic damages can be claimed
  • Strict statutes of limitations apply
  • Experienced legal help is strongly advised

There are no easy answers in misdiagnosis cases. But the right legal expertise on your side can make all the difference seeking justice.
