Tennessee's SB 1664 prohibits healthcare providers from asking minors questions about gender identity, gender confusion, or whether they feel "normal in their body" without a parent being physically present, fully informed, and providing written consent. The bill specifically bans questions like "Do you identify as a gender different from your sex?" unless directly related to diagnosing or treating a current medical or psychological condition. It also prevents health insurers from requiring such questions for payment or penalizing providers who don't ask them. The law applies to all healthcare providers and facilities serving minors under 18, with exceptions for emergencies, mandated child abuse reporting, and minors who are emancipated or parents themselves.
