Gender Affirming Care Isn't Required Under ERISA. That's About to Get Complicated.

No federal law currently requires ERISA-governed health plans to cover gender affirming care. But the regulatory landscape is shifting fast enough that employers who treat this as a settled question are carrying real fiduciary risk.

Does ERISA require coverage of gender affirming care?

No. As confirmed by the Phia Group, there is no federal requirement for plans to cover gender affirming care. An ERISA plan may choose to cover or exclude those benefits. That's still the law today.

Self-funded plans get extra insulation. McDermott Law notes that ERISA preempts state laws relating to employee benefit plans. States generally can't directly mandate gender affirming care coverage in self-funded employer plans, though they retain limited authority over insurers.

But "not required" is not the same as "no rules." The exclusion has to be structured carefully.

What does Section 1557 actually prohibit?

Section 1557 doesn't require you to cover gender dysphoria treatment, but it does prohibit excluding categories of services in a discriminatory way. According to a 2024 Trucker Huss APC Webinar, covered entities must provide coverage in a neutral and nondiscriminatory manner. That's the line that matters.

Courts are watching how plans write these exclusions. The 11th Circuit already held that potential cost savings doesn't excuse discrimination in the context of gender affirming care coverage exclusions, according to analysis from the Horton Group. That precedent is sitting in the record.

If your plan document excludes gender affirming care by name, in a way that treats it differently than comparable services for non-transgender members, you have a discrimination argument waiting to happen. ERISA's general permissiveness doesn't change that.

How is the federal enforcement environment shifting?

It's moving in two directions at once. Both tracks require attention.

On one side, federal agencies with oversight over employer-sponsored health plans have been directed to prioritize enforcement, including criminal enforcement, of statutes restricting gender affirming care for minors, per Seyfarth Shaw LLP. That analysis warns that even ERISA plans not subject to Section 1557 could be affected by downstream effects of executive orders. ERISA doesn't preempt other federal laws or criminal statutes.

On the other side, the federal employee benefits program shifted course. The OPM Carrier Letter for plan year 2026 allows, but doesn't require, coverage for surgeries or hormone treatments meant to facilitate gender transition for individuals above age 19. That reversed OPM Carrier Letter Number 2023-12 from May 2023, which had prevented FEHB and PSHB carriers from excluding those services entirely.

The reversal signals where current administration priorities sit. Employers can legally maintain exclusions for adults, face real risk around minor care regardless of plan design, and need to watch both enforcement tracks simultaneously.

Why should Mental Health Parity rules concern plan sponsors now?

This is the forward-looking piece most employers are missing. The DOL's 2024 and 2025 expansions of Mental Health Parity rules significantly tightened nonquantitative treatment limitation requirements. Gender dysphoria is classified as a mental health condition in the DSM-5. Obesity has a parallel trajectory.

If parity enforcement catches up to how plans handle gender dysphoria, the analysis changes. You can't impose restrictions on mental health conditions that you don't impose on comparable medical or surgical benefits.

That standard already applies. The question is whether enforcement will eventually pull gender dysphoria treatment into the category of conditions where exclusion itself becomes a parity violation. That hasn't happened yet, but the direction of the rules makes this a reasonable three-to-five year planning assumption. Understanding your fiduciary liability under ERISA now is cheaper than defending a parity audit later.

What should employers actually do with their plan documents today?

Start with your plan document language. Blanket categorical exclusions are the highest-risk approach. If you're excluding gender affirming care, the exclusion needs to be written neutrally, applied consistently, and defensible under Section 1557's nondiscrimination standard even if you're not technically a covered entity.

Know where your stop-loss carrier stands. Some carriers are quietly adding exclusions or sublimits for gender affirming care, particularly for high-cost surgical procedures. Review your stop-loss contract language carefully. The article on reading a stop-loss quote without getting buried by the fine print is a good starting point.

Document your decision. Whether you cover or exclude, the fiduciary record should show you considered the legal landscape, weighed the exposure, and made a deliberate plan decision. Silence in the record is not a defense.

Frequently asked questions

Can a self-funded ERISA plan exclude all gender affirming care?

Currently yes. As a matter of federal law, there's no mandate requiring coverage. But the exclusion must be written and applied in a nondiscriminatory way. A categorical exclusion that singles out transgender individuals for different treatment than comparable services receive creates Section 1557 and potential parity exposure. Courts have rejected cost savings as a standalone justification.

Does state law override a self-funded plan's gender affirming care exclusion?

Generally no. ERISA preempts state laws that relate to employee benefit plans, which means state mandates typically can't reach self-funded plans the same way they reach fully insured ones. States retain authority over insurers, so fully insured plans face more state-level exposure. Self-funded employers in states with mandates often use ERISA preemption as a shield, but federal law and criminal statutes aren't preempted.

How does Mental Health Parity connect to gender dysphoria coverage?

Gender dysphoria is a DSM-5 mental health diagnosis. Under the Mental Health Parity and Addiction Equity Act, plans can't impose treatment limitations on mental health conditions that are more restrictive than comparable medical or surgical benefits. As DOL enforcement of nonquantitative treatment limitations tightens under 2024 and 2025 rules, plans that exclude gender dysphoria treatment entirely may face harder parity questions. The DOL hasn't mandated coverage yet, but the regulatory trajectory points toward stricter scrutiny. You can review the full compliance resource hub for current parity guidance updates.

What's the practical risk if my plan document has a categorical gender affirming care exclusion?

The primary risks are an EEOC or Section 1557 discrimination complaint, a DOL parity audit, and participant litigation. The 11th Circuit's ruling on cost savings as a defense narrows the argument employers most often reach for. The secondary risk is stop-loss: review both your plan document and your stop-loss contract together. A court order requiring coverage against a carrier exclusion leaves you holding an unfunded liability.

Should employers cover gender affirming care proactively to reduce risk?

That depends on your workforce, your plan economics, and your legal exposure profile. Coverage eliminates discrimination risk but introduces utilization and stop-loss questions. Exclusion is currently legal but requires careful drafting and ongoing monitoring as parity rules evolve. What's not optional is making a documented, deliberate fiduciary decision either way.
