MO HB392

Establishes the "Adult Health Care Consent Act" to govern health care decisions for adults unable to consent to their own care.

Creates a priority order for decision-makers: court-appointed guardians, attorneys-in-fact under durable power of attorney, spouses, parents, adult children, adult siblings, grandparents, and other close relatives.

Allows health care providers to give treatment without consent in emergencies when no authorized decision-maker is immediately available and delay would risk death, serious disfigurement, or loss of bodily function.

Prohibits health care providers from implementing decisions that contradict a patient's documented religious beliefs or explicit prior instructions given while the patient was able to consent.

Provides liability protections for persons making good-faith health care decisions and for providers who rely on authorized decision-makers, except in cases of negligence.
