Proving Medical Malpractice in New York: The Four Elements

1. A Doctor-Patient Relationship

You must show that the provider owed you a duty of care — usually straightforward, established when a provider agrees to treat you.

2. A Breach of the Standard of Care

The core question is whether the provider deviated from what a reasonably competent provider would have done under the circumstances. This almost always requires expert medical testimony.

3. Causation

You must connect the breach to your injury — showing that the negligence, not just the underlying illness, caused harm. Causation is often the most contested element.

4. Damages

Finally, you must have suffered real harm: additional medical costs, lost income, disability, or pain and suffering.

Deadlines and Lavern's Law

New York's malpractice deadline is generally two and a half years, with Lavern's Law allowing certain cancer-misdiagnosis claims to run from discovery. Because these cases are complex and deadline-sensitive, early legal review is important.
