Establishes the "Designated Health Care Decision-Maker Act", which authorizes certain persons to make health care decisions for certain incapacitated persons

HB 747 creates a legal framework for appointing health care decision-makers for adults who become incapacitated and lack an existing health care proxy, guardian, or durable power of attorney. It establishes a priority order for decision-makers: spouse (unless separated), adult children, parents, siblings, and other close relatives or individuals familiar with the patient's values. The bill requires two physicians to confirm incapacity and ensures health care providers inform potential decision-makers by reviewing medical records and contacting family. This directly affects adults in medical emergencies without prior health care planning, ensuring decisions align with the patient's best interests as defined in the law.
