This bill, titled the "Health Care Freedom for Patients Act of 2025," introduces significant changes to health care policy across several areas. It establishes a new federal program to provide contributions to "Exchange plan HSAs" for eligible individuals enrolled in bronze-level or catastrophic health plans through Affordable Care Act (ACA) Exchanges in 2026 and 2027. These contributions would be $1,000 for enrollees aged 18-49 and $1,500 for those aged 50-64, provided their household income does not exceed 700% of the poverty line. However, these Exchange plan HSAs would have restrictions, prohibiting the use of funds for abortion (with exceptions for rape, incest, or life of the mother) and for any sex trait modification procedures. The legislation also addresses cost-sharing reduction payments, appropriating necessary sums for plan years beginning in 2027, but explicitly prohibiting these funds from being used for qualified health plans that cover abortion, again with exceptions for rape, incest, or to save the mother's life. Furthermore, it amends the ACA to allow all individuals purchasing health insurance in the individual market the option to purchase a catastrophic plan, removing previous eligibility restrictions. Regarding Medicaid and CHIP, the bill reduces the federal medical assistance percentage (FMAP) to 80% for states that provide financial assistance or comprehensive health benefits to non-qualified aliens, excluding lawfully residing children and pregnant women. It also prohibits federal financial participation under Medicaid and CHIP for individuals who have not verified their citizenship, nationality, or satisfactory immigration status, particularly during the period typically allowed for such verification. States would no longer be required to provide medical assistance during this "reasonable opportunity period" unless they opt to do so. Finally, the bill aims to prevent what it terms "wasteful spending" by prohibiting coverage of "gender transition procedures" as an essential health benefit under plans offered by ACA Exchanges, effective January 1, 2027. It broadly defines these procedures to include various surgeries and hormone therapies intended to change an individual's body to no longer correspond to their biological sex, with specific exceptions for medically necessary conditions like disorders of sex development or precocious puberty. Concurrently, it prohibits federal Medicaid and CHIP funding for these same "specified gender transition procedures," applying a similar definition and set of exceptions.
