Misdiagnosis of Medical Condition

Misdiagnosis of Medical Conditions — Your Rights After Delayed or Wrong Diagnosis

Board-Certified Medical Malpractice Attorneys at The Kelly Firm

When you seek medical care, you trust your providers to recognize warning signs, order appropriate tests, and reach an accurate diagnosis in time to prevent harm. A misdiagnosis—including delayed, missed, or wrong diagnosis—can lead to unnecessary procedures, disease progression, disability, or death. If you or a loved one suffered harm because a condition was not diagnosed correctly or in time, you may have a medical malpractice claim. The Kelly Firm’s board-certified malpractice attorneys investigate complex diagnostic errors, determine what went wrong, and pursue full compensation for patients and families.

What Is Medical Misdiagnosis?

Misdiagnosis occurs when a provider fails to identify the correct condition or delays the diagnosis beyond a reasonable time, resulting in harm that could have been avoided with timely, appropriate care. Not every bad outcome is malpractice. A claim arises when the provider deviates from the accepted standard of care and that failure causes injury.

Types of Diagnostic Errors

• Missed Diagnosis — The correct condition is never identified, and the patient receives no targeted treatment.
• Delayed Diagnosis — The correct diagnosis is eventually made, but not soon enough to prevent progression or complications.
• Wrong Diagnosis — The patient is diagnosed with a different condition, leading to ineffective or harmful treatment while the true illness worsens.
• Failure to Recognize Complications — The primary diagnosis is known, but emerging complications are overlooked or minimized.
• Failure to Diagnose Related Conditions — Coexisting illnesses are missed, resulting in incomplete or unsafe treatment plans.

Commonly Misdiagnosed Conditions

Any condition can be misdiagnosed, but certain time-sensitive illnesses are frequently involved in malpractice claims because delay leads to severe injury:

• Heart Attack (MI) — Atypical symptoms, especially in women and younger patients, may be dismissed as anxiety or indigestion.
• Stroke and TIA — Transient symptoms, misread imaging, or failure to use stroke protocols can foreclose lifesaving treatment windows.
• Sepsis and Serious Infections — Failure to recognize systemic infection can lead to shock, organ failure, and death.
• Pulmonary Embolism and DVT — Unexplained shortness of breath or leg swelling may be attributed to benign causes without proper testing.
• Cancers — Breast, colorectal, lung, pancreatic, prostate, melanoma, and cervical cancers are often disputed when screening, imaging, or pathology is mishandled.
• Ectopic Pregnancy and Obstetric Emergencies — Delays can cause internal bleeding, infertility, or loss of life.
• Aortic Dissection — Chest or back pain misread as musculoskeletal can be fatal without rapid diagnosis.
• Fractures and Spinal Cord Injuries — Missed on initial imaging or not followed up, causing permanent damage.
• Autoimmune and Endocrine Disorders — Lupus, multiple sclerosis, thyroid disease, and adrenal crises can masquerade as less serious conditions.

How Diagnostic Errors Happen

Most misdiagnoses arise from a combination of cognitive errors and system failures. Common causes include:

• Premature Closure — Stopping the diagnostic process too early after anchoring on an initial impression.
• Failure to Order or Follow Up Tests — Missing labs, imaging, cultures, or neglecting to review and act on results.
• Inadequate History or Exam — Rushed visits, incomplete documentation, or ignoring red flags reported by the patient or family.
• Poor Communication — Breakdowns during handoffs between departments, unread radiology addenda, or unreturned critical values.
• Protocol Deviations — Ignoring chest pain, stroke, sepsis, or trauma pathways designed to prevent errors.
• Staffing and System Issues — Overcrowded emergency departments, understaffing, and delays in specialist consultation.
• Biased or Atypical Presentations — Dismissing serious disease in younger patients, women, or those with atypical symptoms.

Standard of Care in Diagnosis

The legal question is whether a reasonably careful provider in the same specialty would have made the diagnosis—or acted to rule out dangerous conditions—under the circumstances. Meeting the standard of care generally requires:

• Taking a thorough history and performing an appropriate physical exam.
• Considering a differential diagnosis that includes dangerous possibilities first.
• Ordering, interpreting, and following up on necessary tests in a timely manner.
• Consulting specialists or escalating care when indicated.
• Documenting reasoning, patient instructions, and safety-net advice for return precautions.

What Must Be Proven in a Misdiagnosis Case

To prevail in a malpractice claim, your legal team must establish:

• Duty — A provider–patient relationship existed.
• Breach — The provider deviated from the standard of care in evaluating, testing, interpreting, or following up.
• Causation — The breach led to a worse outcome, additional treatment, or loss of a critical treatment window.
• Damages — Economic losses and human harms that can be compensated.

Expert physicians are typically required to explain the standard of care, how it was breached, and how timely diagnosis would likely have changed the outcome.

Evidence and Investigation

Successful cases are built on meticulous review and independent analysis. Your attorneys will usually:

• Obtain complete records: triage notes, provider documentation, imaging, lab data, and call logs.
• Audit test handling: orders placed, results received, timestamps, flags, and follow-up actions.
• Examine policies and protocols: stroke alerts, sepsis bundles, chest pain pathways, consultation rules.
• Retain experts: emergency medicine, internal medicine, cardiology, neurology, radiology, pathology, obstetrics, oncology, and nursing.
• Reconstruct the timeline: symptom onset, first contact, testing, disposition, and return visits.
• Quantify damages: medical bills, lost earnings, life-care planning, and non-economic harms.

Damages Available in Misdiagnosis Cases

• Economic Damages — Past and future medical expenses, medications, rehabilitation, adaptive equipment, lost wages, and reduced earning capacity.
• Non-Economic Damages — Pain and suffering, emotional distress, loss of enjoyment of life, and loss of consortium.
• Punitive Damages — In rare cases involving reckless or willful disregard for patient safety.

For permanent injuries, damages should account for lifelong treatment, loss of independence, and necessary home or vehicle modifications.

Time Limits: Statutes of Limitations

Medical malpractice claims are time-sensitive. Each state sets a deadline to file, and some impose a statute of repose that bars claims after a fixed period regardless of discovery. Special timing rules may apply to minors, wrongful death, or government-run facilities. Contact an attorney promptly to preserve your rights and critical evidence.
