Human services: county services; designation of a patient surrogate for health care decisions; allow. Amends sec. 66h of 1939 PA 280 (MCL 400.66h).

HB 4734 expands who can legally consent to medical treatment for patients unable to make decisions themselves. It adds "designated surrogates" (people formally appointed under Michigan's Estates Code) to the list of authorized decision-makers, alongside relatives, patient advocates, and guardians. This directly affects patients without decision-making capacity, healthcare providers needing consent, and the individuals authorized to act for them. The bill clarifies that emergency care can still be provided without consent during urgent situations requiring immediate action.
