Medical malpractice in New York happens when a healthcare provider departs from the accepted “standard of care” — what a reasonably careful provider would have done in the same situation — and that failure directly causes injury to the patient. A bad result by itself is not malpractice. There must be both negligence (a provider doing something they should not have, or failing to do something they should have) and a causal link between that negligence and the harm.
Many people assume that a bad medical outcome means malpractice occurred. New York law does not work that way. Medicine carries risk, and even careful, skilled providers sometimes have patients who do poorly. Malpractice is narrower: it is about whether the care fell below a professional standard, not whether the result was unfortunate.
The legal anchor is the “standard of care” — what a reasonably prudent provider in the same field would have done under the same circumstances. Proving malpractice generally requires expert testimony from another medical professional explaining how the defendant deviated from that standard. Without that expert support, a case rarely moves forward.
Negligence alone is also not enough — there must be causation. The patient has to show that the provider’s failure actually caused the injury, not that it was merely present alongside a bad outcome. A mistake that caused no additional harm usually is not a viable malpractice case.
Because these cases turn on medical standards, expert review, and causation, they are among the more complex areas of law. Most people who suspect malpractice consult a New York malpractice attorney, who will typically have the records reviewed by a medical expert before deciding whether a claim exists.
