In December 2025, the Trump administration escalated its efforts to restrict gender-affirming care (GAC) for transgender youth through a sweeping set of federal actions that go far beyond existing state bans. Under proposals released by the Department of Health and Human Services, children and adolescents under 18 would be barred from accessing gender-affirming medical care nationwide—not through an act of Congress, but by threatening the financial survival of hospitals and health systems that provide it.
Already, more than half of U.S. states ban or severely limit gender-affirming care for minors, according to the Kaiser Family Foundation. The new federal proposals would extend those restrictions even into states that protect access, effectively creating a national ban through funding leverage rather than lawmaking.
How the Proposed Rules Work
The administration announced three interlocking actions on Dec. 18 that together would dramatically curtail care for transgender youth.
First, the Centers for Medicare & Medicaid Services (CMS) proposed a new Condition of Participation rule that would require hospitals to stop providing gender-affirming care to anyone under 18 as a prerequisite for receiving any Medicare or Medicaid funding. This requirement would apply regardless of whether a patient uses private insurance or pays out of pocket. For most hospitals, participation in these federal programs is not optional—making compliance all but unavoidable.
Second, CMS proposed a separate rule that would ban federal Medicaid and the Children’s Health Insurance Program funding for gender-affirming care for youth. Medicaid coverage would be prohibited for patients under 18, while CHIP coverage would be barred for those under 19. Even if a doctor determines that care is medically necessary for an individual patient, federal funds could not be used.
Third, HHS Secretary Robert F. Kennedy Jr. issued an unprecedented declaration, asserting that gender-affirming care for youth is “neither safe nor effective.” Legal experts warn that this declaration could be used to justify excluding providers from federal health programs altogether—without the usual public notice-and-comment process required for major policy changes.
Why This Is Unprecedented
CMS has never before conditioned Medicare or Medicaid participation on the elimination of a specific medical service, particularly one supported by major medical organizations. If upheld, this approach could set a powerful precedent: allowing the federal government to dictate which medical services hospitals may offer, even when those services are legal under state law and supported by clinical evidence. Health policy experts warn that the same mechanism could later be used to target other politically controversial forms of care, from reproductive health services to mental health treatments.
