Minors; prohibit health care providers and institutions from providing health care to without parental consent.

HB 478 requires Mississippi healthcare providers to give parents a written notice at minor visits about their right to block others from consenting to their child's medical treatment. Parents can also designate specific adults (like grandparents or siblings) authorized to consent for their child. Providers must obtain parental consent (or a designated adult's) before treating unemancipated minors, with a 72-hour window to contact parents if consent isn't immediately provided. Exceptions include emergencies, mental health care, certain infectious disease treatments, and cases involving the Department of Child Protection Services.
