House Bill 1872, sponsored by Zachary, amends Tennessee law to establish a new legal framework for private causes of action against healthcare professionals. The bill defines key terms such as "healthcare professional," "medical procedure," "minor," "person," and "sex." It allows individuals to bring civil actions for compensatory and punitive damages against healthcare professionals if they have undergone medical procedures aimed at aligning their identity with a gender inconsistent with their biological sex, particularly if such procedures were performed under coercion.

The bill stipulates that actions must be initiated within a specific timeframe, allowing claims for procedures performed before the act's effective date or within eighteen years of the procedure if it occurred after the act's enactment. Additionally, it includes a severability clause to ensure that if any part of the act is deemed invalid, the remaining provisions will still be enforceable. The act is set to take effect upon becoming law, emphasizing the public welfare.
