MS HB1155

Requires health-care providers to present parents or guardians with a written document at each minor patient visit (after July 1, 2025) explaining their right to restrict who can consent to medical treatment and to designate additional authorized adults.

Prohibits health-care institutions and providers from treating unemancipated minors without first obtaining consent from the parent, guardian, or parent-designated adult; allows other family members (custodian, adult sibling, or grandparent) to consent only if no parent or guardian-designated adult responds within 72 hours.

Establishes exceptions to the parental consent requirement for mental illness cases, emergencies, judicial consent, blood donations by minors 16+, infectious disease testing, CPS custody situations, inmates, safe haven drop-offs, suspected parental abuse or neglect, and athletic trainer care at school or youth sports events.

Allows parents, guardians, or surrogates to sue for violations and recover declaratory relief, injunctive relief, damages, attorneys' fees, and other appropriate relief; waives sovereign and governmental immunity for such claims.

Repeals existing statutes allowing physicians to treat minors for venereal disease or substance-related mental health issues without parental consent; amends contraceptive supply provisions to require parental consent compliance.
