The U.S. Department of Health and Human Services (HHS), along with the Office for Civil Rights (OCR) and the Centers for Medicare & Medicaid Services (CMS), has announced several significant regulations under the Affordable Care Act (ACA). These include extending antidiscrimination provisions to patient care decision support tools such as algorithms under ACA Section 1557, and prohibiting discrimination in health care related to the use of artificial intelligence. Additionally, HHS has issued a final rule on reproductive health care privacy and expanded the definition of 'sex' in healthcare settings to include 'gender identity'. CMS also released a final rule to ensure access to Medicaid services.
