Provides certain requirements for health care proxies and death certificates

This bill updates New York's health care proxy and death certificate rules. It requires health care proxies to be signed before a notary (replacing witness requirements) and specifies that agents must follow a patient's known wishes or best interests when making medical decisions. Crucially, agents cannot decide to withdraw artificial nutrition or hydration without written agreement from two non-attending doctors, and if such a decision causes death, the death certificate must note this. The changes directly affect patients appointing agents, their medical agents, and healthcare facilities handling end-of-life documentation.
