Four New Hampshire families have sued the federal government to block a rule that would end Medicaid and CHIP coverage for trans youth care, days before the cutoff takes effect on October 13, 2026. The lawsuit, filed in federal court in New Hampshire on October 1, 2026, asks a judge to pause the policy before it strips funding mid-treatment from low-income young people whose doctors prescribed the care.

The rule, issued in August by the Centers for Medicare and Medicaid Services, bars federal Medicaid dollars from paying for trans youth care — gender-affirming surgeries and hormone treatments — for patients under 18, and blocks the Children's Health Insurance Program from covering the same treatments for people under 19, as reported by the Associated Press. Mental health services stay covered, and young people already receiving hormone treatment get a tapering window through April 2027. After that, the federal money stops.

What the rule changes for trans youth care

For families on public insurance, the practical effect is stark: states that want to keep covering the treatments through Medicaid or CHIP would have to pay for them entirely on their own, according to the AP's reporting. President Trump directed CMS Administrator Dr. Mehmet Oz to make the change, calling the procedures "barbaric" in a social media post and arguing that children face irreversible harm.

The scope of the trans youth care being defunded matters. Gender-affirming surgeries for minors are rare, while puberty blockers and hormone treatments are the more common interventions. The rule phases out coverage of those hormone treatments for current patients by April 2027, giving families already in treatment a six-month wind-down rather than an immediate cutoff.

Why the families are going to court

The New Hampshire teenagers at the center of the case, ages 11 to 15, are already in treatment, with their identities sealed to protect their medical privacy. Their families made the decisions with doctors after careful assessment, and they are represented by GLAD Law, the National Center for LGBTQ Rights, and the ACLU of New Hampshire.

The complaint argues the rule is unlawful on several grounds, as reported by Boston Spirit Magazine. Congress never gave any president the power to override Medicaid's decades-old guarantee that children receive all medically necessary care, the filing says, and the agency admits it has never before declared a whole category of services "inherently not medically necessary."

The filing also points to the public comment process: more than 90 percent of the comments submitted on the rule opposed it, and the lawsuit argues the government pressed ahead anyway. Chris Erchull, a senior staff attorney for the plaintiffs, said the administration wants to "pull the funding for their care mid-treatment," with no plan for what happens to the kids next.

A wider fight over trans youth care access

The federal funding fight is the latest front in a much wider battle over trans youth care. At least 27 states have already banned gender-affirming care for people under 18, and even where care remains legal, many major hospitals have quietly stopped providing some of it. The American Medical Association and most other major medical organizations support access to the treatments, though the American Society of Plastic Surgeons said earlier this year it found insufficient evidence that the benefits of surgeries on minors outweigh the risks.

Legal challenges are stacking up on multiple fronts. The Human Rights Campaign is already suing over efforts to bar coverage under federal employee benefit plans. The Supreme Court has let the administration's passport policy stand while allowing states to enforce sports bans, and a lower court ruled against the administration's declaration that the treatments are unsafe and ineffective.

What happens next

The families are asking the court to act fast. If the judge declines to intervene before the effective date, low-income families would face a choice their wealthier neighbors do not: pay out of pocket or stop the trans youth care their doctors recommended. "Trump is telling families: if you can't afford to pay out-of-pocket, your children will have to go without the care they need," according to the organization's case page.

For young people watching this fight, the next hearing could decide whether Medicaid must cover trans youth care the same way it covers everything else, or whether the government can single out one diagnosis for exclusion.
