Modifies provisions relating to gender transition procedures

Missouri HB 1854, known as the "Missouri Save Adolescents from Experimentation (SAFE) Act," prohibits health care providers from performing gender transition surgeries or prescribing cross-sex hormones and puberty-blocking drugs to individuals under 18 years old. The law directly affects minors seeking gender-affirming medical care and their licensed health care providers. It includes a grandfather clause allowing continued treatment for minors already receiving such care before August 28, 2023, until March 1, 2027. Violations would be considered unprofessional conduct, potentially leading to license revocation, and could also form the basis for legal claims against providers.
