HHS proposed regulations would bar medical providers from receiving Medicare or Medicaid funds if they offer puberty blockers, hormone therapy or procedures such as mastectomies to minors, following a declaration signed by Robert F. Kennedy Jr. directing the Department of Health and Human Services to withdraw federal funding from hospitals that provide gender-affirming care to children.The regulatory track builds on earlier HHS rules and runs alongside a House measure, H.R. 3492, that would criminalize prescribing puberty blockers or hormone therapy to transgender adolescents and passed the House 216 to 211 after Marjorie Taylor Greene secured floor consideration; a separate bill from Dan Crenshaw would bar federal Medicaid funding for transition procedures but faces hurdles in the Senate.Medical organizations including the AAP, ACOG and APA and civil-rights groups such as the ACLU, PFLAG and GLMA warned of ethical conflicts and a chilling effect on care, and HHS officials acknowledge the measures will be litigated as federal judges have already blocked similar state bans and the department must follow the Administrative Procedure Act.
