What the insurance company does not want you to know about this is that signing discharge papers is not a waiver, and in New York an informed consent claim turns on very specific proof.

1. Show there was a decision requiring meaningful consent. Under New York Public Health Law § 2805-d, informed consent usually applies to a non-emergency treatment, procedure, or invasive diagnostic test where a reasonable patient would want to know the risks, benefits, and alternatives. It usually does not cover a pure misdiagnosis by itself. In a Brooklyn ER case during flu season, the key question is whether staff made a discharge-related medical decision without properly explaining the risk of serious conditions being mistaken for flu, and the available alternatives such as observation, imaging, labs, or admission.

2. Get the exact records, not just the discharge sheet. Ask for the full chart from places like Brooklyn Hospital Center or Interfaith Medical Center: triage notes, nursing notes, physician notes, vital signs, test orders, medication records, discharge instructions, and any signed consent or refusal forms. In overcrowded ERs, charts often show whether the patient had fever, low oxygen, abnormal heart rate, worsening pain, neurological symptoms, or sepsis indicators that made discharge risky.

3. Prove what you were told - and what you were not told. The strongest evidence is often the gap between the chart and reality. If nobody warned about red-flag symptoms, return precautions, or the risk of a serious condition being dismissed as flu, that matters. Witnesses who were present, text messages sent that night, portal messages, ambulance records, and the later hospital admission can all help show the discussion was inadequate.

4. Connect the missing warning to the harm. You must show a reasonable person would have chosen differently if properly informed, and that the lack of information led to injury. A rapid return to the hospital in worse condition is important proof. In New York, the usual malpractice deadline is 2 years and 6 months from the malpractice or from continuous treatment.
