A timely, accurate diagnosis can mean the difference between recovery and a lifetime of complications. When a doctor fails to recognize a serious illness—or diagnoses it too late—the results can be devastating. Our NYC misdiagnosis lawyers represent patients and families across Manhattan, Brooklyn, Queens, the Bronx, Staten Island, and Long Island who suffered because a medical professional failed to diagnose a condition correctly and in time.

When Doctors Get It Wrong

You trust your healthcare providers to listen, investigate, and treat you with the urgency your symptoms demand. When they don’t, conditions like cancer, stroke, or severe infections can progress unchecked. We help patients and families navigate the legal process when misdiagnosis or delay has caused unnecessary pain, invasive treatments, or loss of life.

Common Misdiagnosis Scenarios

Misdiagnosed Chronic Conditions 

Autoimmune diseases or neurological disorders labeled as something less serious, delaying proper treatment.

Why Misdiagnosis Happens

These errors often stem from:


  • Not ordering the right tests.

  • Failing to review lab or imaging results carefully.

  • Rushing through patient exams.

  • Attributing symptoms to less serious causes without ruling out dangerous conditions.

When a doctor fails to meet the standard of care in diagnosing a patient, it can be grounds for a malpractice claim.

The Cost of a Delayed Diagnosis

Medical conditions that could be managed or cured early may become far more dangerous if caught late. A lump ignored for months may become inoperable cancer. A minor infection can escalate into septic shock. These outcomes aren’t just medical setbacks—they’re life-altering events that carry physical, emotional, and financial burdens.


How We Build Your Case

Our team works with board-certified specialists to examine your records, reconstruct the diagnostic process, and identify where it went wrong. We look at whether the doctor followed proper “differential diagnosis” protocols and whether serious conditions were ruled out appropriately. If not, we hold them accountable.

Frequently Asked Questions

  • Is a misdiagnosis always malpractice?

    No. To be malpractice, the error must be due to negligence—meaning the doctor failed to act as a reasonably skilled physician would have in the same situation.

  • What if I didn’t realize I was misdiagnosed until later?

    You may still have a case. New York law allows a certain window to file after you discover—or reasonably should have discovered—the malpractice. Contact a lawyer quickly to preserve your rights.
