MO HB100

Establishes the "Adult Health Care Consent Act" creating a priority order for making health care decisions on behalf of adults unable to consent, with guardians, attorneys-in-fact, and spouses having highest priority, followed by family members and close personal relationships.

Requires inability to consent be certified by two licensed physicians who have examined the patient, though in emergencies a single health care professional may certify if delay would be detrimental to the patient's health.

Allows health care to be provided without consent in emergencies when authorized decision-makers are unavailable and delay presents substantial risk of death or serious bodily harm, or for relief of suffering when no authorized person is available.

Prohibits health care decisions contrary to a patient's known religious beliefs or unambiguous prior instructions expressed when able to consent, unless the patient previously stated contrary intent to the health care provider.

Provides civil and criminal liability protection for persons making good faith health care decisions and health care providers relying in good faith on authorized decisions, with exception for negligent care; prohibits consent to treatment that would harm a fetus except to protect the mother's life.
