Under this act, no physician or other health care provider shall knowingly provide gender transition procedures to any minor and shall not refer a minor to any health care provider for such procedures.

No public funds, including MO HealthNet funds, shall be used to provide gender transition services to minors. A violation of the provisions of this act shall be considered unprofessional conduct, and shall be grounds for a cause of action against the physician or health care provider, as described in the act. The Attorney General may enforce compliance with the provisions of this act. This act shall not apply to the provision of cross-sex hormones to any minor who was prescribed such before January 1, 2024, to treat an inconsistency between the individual's biological sex and the individual's perceived gender or perceived sex. Additionally, the provisions of this act shall not become effective until January 1, 2024.
