Federal Court Strikes Down Trump Rule That Tried to Strip Gender-Affirming Care From ACA Protections

A federal judge in Massachusetts handed transgender Americans a significant, if narrow, victory this week, striking down a Trump administration rule that would have excluded certain types of gender-affirming care from the Affordable Care Act’s essential health benefits.

The U.S. District Court for the District of Massachusetts ruled that the administration acted unlawfully when it tried to redefine what counts as an essential health benefit under the ACA without following the notice-and-comment procedures federal law requires. The ruling addressed the last unresolved piece of a “Marketplace Integrity and Affordability” rule the administration proposed back in March 2025 — nine provisions in total, seven of which were already vacated earlier this year in a related case out of Maryland, City of Columbus et al. v. Kennedy et al. This week’s decision closes out the rest.

Why essential health benefits matter

The ACA requires marketplace insurance plans to cover ten categories of essential health benefits, and those categories come with real teeth: annual out-of-pocket spending caps, protections against arbitrary denials, and limits on how insurers can structure cost-sharing. If gender-affirming care had been carved out of those categories, insurers selling ACA marketplace plans could have imposed higher deductibles, separate caps, or outright exclusions on hormone therapy, surgical care, and related treatment for transgender enrollees — without running afoul of the law, because that care would no longer carry the ACA’s baseline protections.

That’s the mechanism the rule targeted, and it’s why the ruling matters beyond the specific provision at issue. It doesn’t mandate that every plan cover every type of gender-affirming care. What it does is preserve the legal floor that keeps the care that is covered inside the ACA’s consumer protections, rather than letting insurers treat it as a second-tier benefit.

A multistate fight, not a single lawsuit

California Attorney General Rob Bonta co-led the coalition that brought the case, alongside the attorneys general of Massachusetts and New Jersey. The states filed suit in July 2025, arguing the rule’s nine provisions collectively would make ACA coverage harder to get, more expensive for states to administer, and weaker across several of its core consumer protections.

“Everyone deserves access to health coverage,” Bonta said in a statement following the ruling. “The Trump administration tried to exclude gender-affirming care from qualifying as an essential health benefit. We fought back, and the court’s ruling means this care can — and in many states must — qualify for the ACA’s financial protections, ensuring transgender people have an equal opportunity to benefit from the ACA.”

The court’s reasoning was procedural rather than a broad constitutional statement on transgender rights: it found that the administration changed the essential-benefits framework without going through the standard rulemaking process the Administrative Procedure Act demands. That’s a narrower basis than a ruling on the merits of coverage itself, but it’s also one of the more durable ways to win this kind of case, since it doesn’t hinge on how a higher court might eventually view gender-affirming care as a policy matter.

The bigger picture on federal health policy

This ruling arrives less than a week after the Centers for Medicare & Medicaid Services finalized a separate rule cutting off federal Medicaid and CHIP matching funds for gender-affirming care for minors, effective in October. Together, the two actions show an administration pursuing the same broad goal — narrowing where and how gender-affirming care gets covered by public and subsidized private insurance — through multiple regulatory channels at once, with mixed results in court so far.

It’s also a reminder of how much of the current fight over trans health care access is happening in the details of insurance regulation rather than in headline-grabbing bans. Essential health benefit categories, Medicaid matching rates, and CMS billing codes don’t generate the same attention as a state legislature debate, but they determine, in very concrete terms, what a transgender person actually pays out of pocket for care that a doctor has already prescribed.

Whether the administration appeals this particular ruling remains to be seen. Given that the companion provisions were already vacated in the Maryland case, legal observers expect the administration’s options for reviving this specific exclusion are limited without going back through a full, lawful rulemaking process — the very step the court found the administration skipped the first time.
