ACA Section 1557 Nondiscrimination

Current understanding

Section 1557 of the Affordable Care Act prohibits discrimination on the basis of race, color, national origin, sex, age, or disability in health programs and activities that receive federal financial assistance. HHS’s 2024 final rule implementing Section 1557 expanded protections including on the basis of gender identity, but a federal district court has vacated the gender-identity discrimination provisions, leaving the remainder of the rule in force. The scope of covered entities includes most hospitals, insurers, and providers participating in Medicare (excluding Part B) and Medicaid.
