Misdiagnosis Lawsuit: Can You Sue for Misdiagnosis?
Written by the Hughes and Barnard Law Firm, PA marketing team and reviewed by Attorney Howard Hughes to ensure quality and accuracy.
When you’re sick or injured, you trust your healthcare providers to identify what’s wrong and recommend the appropriate treatment. Unfortunately, diagnostic mistakes happen more often than many people realize. A missed diagnosis, delayed diagnosis, or incorrect diagnosis can allow a serious medical condition to worsen, sometimes leading to life-changing consequences.
In some cases, a diagnostic error may mean the difference between early treatment and advanced disease. Patients may undergo unnecessary procedures, receive the wrong medications, or lose valuable time that could have been used to treat the actual condition.
If you suffered harm because a healthcare provider failed to diagnose your condition correctly, you may be wondering whether you have grounds for a misdiagnosis lawsuit.
Key Takeaways
- A misdiagnosis occurs when a healthcare provider incorrectly identifies a medical condition.
- A delayed diagnosis or failure to diagnose can also lead to serious harm.
- Not every diagnostic mistake is medical malpractice.
- You may have grounds for a lawsuit if a healthcare provider's negligence caused your injury.
- Compensation may be available for medical expenses, lost income, pain and suffering, and other damages.
What Is a Medical Misdiagnosis?
A medical misdiagnosis occurs when a healthcare provider incorrectly diagnoses a patient’s condition. Rather than identifying the actual illness or injury, the provider attributes symptoms to another condition.
For example, a patient experiencing a heart attack may be diagnosed with acid reflux, or early signs of cancer may be mistaken for a less serious illness. While some diagnostic errors may have little impact on a patient’s outcome, others can have devastating consequences.
Misdiagnosis cases generally fall into one of three categories:
Misdiagnosis
The wrong condition is diagnosed.
Delayed diagnosis
The correct diagnosis is eventually made, but valuable treatment time is lost.
Failure to diagnose
The condition is never properly identified.
Each of these situations can potentially form the basis of a medical malpractice claim if negligence contributed to the error.
Can You Sue for Misdiagnosis?
Yes, you may be able to sue for misdiagnosis if a healthcare provider’s negligence caused harm.
However, not every incorrect diagnosis automatically qualifies as medical malpractice. Medicine is complex, and doctors are not expected to be perfect. The law generally focuses on whether the healthcare provider acted reasonably under the circumstances.
A valid misdiagnosis lawsuit typically involves more than simply proving that a diagnosis was wrong. It must also be shown that the provider failed to meet the accepted standard of care and that this failure directly caused injury or worsened the patient’s condition.
In other words, the key question is whether another reasonably competent healthcare provider would likely have recognized the condition or taken additional steps to reach the correct diagnosis.
Common Conditions Involved in Misdiagnosis Lawsuits
Some conditions are more frequently associated with diagnostic errors because their symptoms can resemble less serious illnesses.
Common examples include:
Cancer
A delayed cancer diagnosis can allow the disease to spread, reducing treatment options and affecting a patient’s prognosis.
Heart Attacks
Heart attack symptoms are not always obvious. When warning signs are overlooked or misinterpreted, the consequences can be catastrophic.
Stroke
Prompt treatment is critical for stroke patients. Even a short delay in diagnosis can significantly affect recovery and long-term outcomes.
Sepsis and Serious Infections
Infections that are not recognized and treated promptly can progress rapidly and become life-threatening.
Neurological Disorders
Conditions affecting the brain, spinal cord, and nervous system may be difficult to diagnose, but delays can result in permanent injury.
Internal Injuries
Traumatic injuries and internal bleeding may not always be immediately apparent. Failure to diagnose these conditions can place patients at serious risk.
How Can a Misdiagnosis Harm a Patient?
The consequences of a diagnostic error can extend far beyond the initial mistake.
When a condition goes untreated, it may continue to progress. Patients may experience worsening symptoms, additional complications, or a reduced likelihood of successful treatment.
In some cases, patients receive treatment for a condition they never had. This can expose them to unnecessary medications, surgeries, procedures, and side effects while the actual condition remains untreated.
Potential consequences of a misdiagnosis may include:
- Disease progression
- Permanent disability
- Additional medical complications
- Unnecessary treatment
- Increased medical expenses
- Lost income
- Reduced quality of life
- Wrongful death
The impact varies from case to case, but the effects can be both physically and emotionally devastating.
What Evidence Is Used in a Misdiagnosis Case?
Every case is unique, but several types of evidence are commonly used in medical malpractice claims.
Medical records often play a central role because they document symptoms, examinations, test results, diagnoses, and treatment decisions.
Additional evidence may include:
- Diagnostic imaging
- Laboratory results
- Prescription records
- Specialist consultations
- Expert medical opinions
- Employment and wage records
- Documentation of medical expenses
The stronger the evidence linking the diagnostic error to the patient’s injury, the stronger the potential claim may be.
What If Your Employer Pressures You to Return Too Soon?
Unfortunately, some injured workers feel pressured to return to work before they’re medically ready.
Returning too early can place your recovery at risk and may even worsen your condition. Your work status should be determined by your authorized treating physician, not by pressure from your employer or insurance company.
If your doctor has imposed restrictions, those restrictions should be taken seriously. Attempting duties beyond your medical limitations could negatively affect both your health and your claim.
If you’re facing pressure to return before you’re ready, documenting communications and seeking legal advice may help protect your rights.
What Happens If Workers’ Comp Is Denied?
A denial can feel overwhelming, especially when you’re already dealing with an injury and financial stress. However, a denial does not necessarily mean the end of your case.
Workers’ compensation claims may be denied for many reasons, including:
- Diagnostic imaging
- Laboratory results
- Prescription records
- Specialist consultations
- Expert medical opinions
- Employment and wage records
- Documentation of medical expenses
The stronger the evidence linking the diagnostic error to the patient’s injury, the stronger the potential claim may be.
What Compensation Can Be Recovered?
If a healthcare provider’s negligence caused injury through a misdiagnosis, compensation may be available for both economic and non-economic losses.
Depending on the circumstances, damages may include:
- Medical expenses
- Future medical care
- Lost wages
- Loss of earning capacity
- Pain and suffering
- Emotional distress
- Disability or disfigurement
- Wrongful death damages
The value of a claim depends on factors such as the severity of the injury, the long-term impact on the patient’s life, and the extent of financial losses.
How Long Do You Have to File a Misdiagnosis Lawsuit?
Medical malpractice claims are subject to legal deadlines known as statutes of limitations.
The amount of time you have to file a lawsuit depends on several factors, including the state where the malpractice occurred and when the injury was discovered.
Because these deadlines can significantly affect your rights, it is important to speak with an attorney as soon as possible if you believe a misdiagnosis caused you harm.
What Should You Do If You Believe You Were Misdiagnosed?
If you suspect that a healthcare provider failed to diagnose your condition correctly, taking prompt action can help protect both your health and your legal rights.
Seeking a second medical opinion may help confirm the correct diagnosis and ensure that you receive appropriate treatment moving forward.
It is also important to obtain copies of your medical records and keep documentation related to your medical care, expenses, and symptoms.
Most importantly, consider speaking with a medical malpractice attorney who can evaluate your situation and determine whether you may have a valid claim.
