To amend the Patient Protection and Affordable Care Act to ensure that taxpayer funds for health insurance coverage are available only to authorized individuals, and for other purposes.

HR7817, titled the "No Federal Tax Dollars for Illegal Aliens Health Insurance Act of 2026," was introduced in the House of Representatives on March 5, 2026, by Rep. Boebert and 14 cosponsors. The bill has been referred to the Committee on Energy and Commerce and the Committee on Ways and Means. This early stage of the legislative process indicates that the bill has significant steps remaining before it could become law. The bill amends sections 1332(a)(2)(B) and 1332(a)(3) of the Patient Protection and Affordable Care Act. Specifically, it seeks to prohibit the use of federal funds, including pass-through funding to states, to offset the cost of health insurance coverage or provide other benefits for individuals who are not citizens, nationals, or lawfully present aliens in the United States. It also mandates the rescission of any waivers approved under section 1332 that would not have been approved if these amendments were in effect. The bill does not authorize or appropriate any specific funding amount; instead, it aims to restrict the eligibility for existing ACA subsidies, which could reduce the total addressable market for health insurers participating in the ACA marketplace. Structural losers, if this bill were to pass, would be health insurers with significant exposure to the ACA marketplace, as the pool of individuals eligible for subsidies would shrink. Companies like UnitedHealth Group ($UNH), Humana ($HUM), and Centene Corporation ($CNC) operate in this space. However, the bill's impact on these large, diversified insurers would depend on the proportion of their revenue derived from the ACA marketplace and the number of individuals affected. The bill's current status in committee means any direct financial impact is speculative at this time. Despite the introduction of HR7817, health insurer stocks have shown recent positive movement. UnitedHealth Group ($UNH) is currently at $281.36, with a 7-day change of +7.48% and a 30-day change of -2.57%. Centene Corporation ($CNC) is at $35.4, with a 7-day change of +11.32% and a 30-day change of -18.19%. Humana ($HUM) is not provided in the market data. The positive 7-day performance suggests that the market is not currently pricing in a significant negative impact from this early-stage bill. The bill's legislative path involves committee consideration, potential floor votes in the House and Senate, and presidential assent, indicating a lengthy process ahead.
