Self-insured employer health plans are exempt from all state fertility mandates, leaving the majority of American workers without coverage

Although 22 US states plus Washington D.C. have enacted laws requiring insurance coverage for fertility treatments, these mandates only apply to fully insured plans regulated under state law. Self-insured plans, which are governed by federal ERISA law, are completely exempt from state fertility mandates and cover the majority of workers at large employers. Why it matters: self-insured plans cover approximately 65% of workers with employer-sponsored insurance, so the majority of American employees have no legally guaranteed access to fertility coverage regardless of which state they live in, so even in states with strong fertility mandates like Illinois or Massachusetts, most workers at large employers (Amazon, Google, Walmart, etc.) only receive fertility benefits if their employer voluntarily provides them, so fertility coverage becomes a function of employer generosity rather than a legal right, so workers at smaller companies or those in less competitive industries are systematically disadvantaged. The structural root cause is that the federal ERISA preemption, established in 1974, prevents states from regulating self-insured employer health plans, and Congress has not passed any federal legislation mandating fertility coverage, creating a regulatory gap that no amount of state-level legislation can close.
