When a doctor fails to correctly identify your condition — or diagnoses it too late — the result can be irreversible harm. Misdiagnosis is one of the most common and dangerous forms of medical negligence in New York.
Misdiagnosis affects an estimated 12 million Americans each year. In New York, it is actionable as medical malpractice when a provider's failure to follow the diagnostic standard of care — such as skipping a proper differential diagnosis, ignoring abnormal results, or dismissing serious symptoms — causes harm. Below you'll find our deep-dive guides organized by condition, defendant, and legal issue. Each explains the standard of care, how we prove the delay caused harm, and the filing deadlines that apply.
How doctors should evaluate symptoms — and when cutting corners becomes malpractice.

What misdiagnosis claims are worth and how we prove the delay caused harm.
Misdiagnosis means a healthcare provider failed to correctly identify your condition — either by diagnosing the wrong condition or by missing the correct one entirely. When that error deviates from the accepted standard of care and causes harm (such as disease progression or delayed treatment), it can support a medical malpractice claim.
A misdiagnosis means the wrong diagnosis was given. A delayed diagnosis means the correct diagnosis was eventually made, but too late. Both are actionable in New York when negligence caused the error and the error caused harm.
Under CPLR § 214-a, generally 2.5 years from the date of the malpractice. Under Lavern's Law, cancer misdiagnosis claims run 2.5 years from the date you discovered (or should have discovered) the error, with a 7-year outer limit. For wrongful death, 2 years from the date of death under EPTL § 5-4.1.
Yes. New York requires qualified medical expert testimony to establish the standard of care, show how the provider deviated from it, and prove that the deviation caused your injury.
