Twenty-Two States Sue Trump Administration to Block Medicaid Ban on Youth Gender-Affirming Care
In a major escalation of state-level resistance to federal executive authority, a coalition of 22 Democratic-led states and the District of Columbia filed a federal lawsuit on Wednesday, September 2, 2026, challenging a new Trump administration rule1 that bans federal Medicaid and Children’s Health Insurance Program (CHIP) reimbursement for gender-affirming care for minors.
The lawsuit, filed in the U.S. District Court for the District of Massachusetts and co-led by Massachusetts Attorney General Andrea Joy Campbell, targets a final rule issued in August by the Centers for Medicare & Medicaid Services (CMS). The rule, scheduled to take effect on October 13, 2026, categorically excludes medically necessary gender-affirming treatments from federal reimbursement for Medicaid beneficiaries under age 18 and CHIP beneficiaries under age 192.
The plaintiff states argue that the rule represents an unlawful executive overreach that violates the Administrative Procedure Act, the Spending Clause of the U.S. Constitution, and established statutory authority. They assert that since the 1960s, Congress has granted states the authority to determine covered services under Medicaid, and that CMS is acting without statutory authority to override state medical necessity determinations.
Attorney General Campbell framed the lawsuit as a defense of state authority and children's healthcare access against unlawful federal encroachment.
“The Trump Administration’s latest attack on access to gender-affirming care for young people unlawfully undermines states’ authority to regulate healthcare and tries to strip healthcare access from vulnerable kids. Gender-affirming care remains legal and protected in Massachusetts, and we will not allow the federal government to dictate what care our patients receive.”
The complaint argues that the rule sets a dangerous precedent by allowing the federal executive branch to substitute its own political judgments for the individualized medical decisions of licensed healthcare providers.
“In their complaint, AG Campbell and the coalition argue that the rule would set a troubling and unlawful precedent that the executive branch can, without congressional authorization, replace individualized judgments made by licensed medical practitioners with a categorical, agency-determined prohibition on reimbursement for healthcare it disfavors.”
The lawsuit marks the latest front in a broader legal war over LGBTQ+ healthcare. Prior to this filing, federal courts had already blocked other Trump administration efforts to restrict gender-affirming care under the Affordable Care Act and through Medicare.
Joining Massachusetts in the lawsuit are the attorneys general of California, Colorado, Connecticut, Delaware, Hawaii, Illinois, Maine, Maryland, Michigan, Minnesota, Nevada, New Jersey, New York, Oregon, Rhode Island, Vermont, Virginia, Washington, Wisconsin, and the District of Columbia, alongside the governor of Pennsylvania.
