evidence: "Tens of thousands of South Dakotans now have an opportunity to obtain health care coverage, and the peace of mind it provides, as a result of Medicaid expansion," said HHS Secretary Xavier Becerra. "The comprehensive health insurance that Medicaid provides can be life changing for American families. I urge the remaining states yet to adopt expansion to do so." "Medicaid is a lifeline for millions of people, and a cornerstone for achieving health equity – particularly for underserved communities," said CMS Administrator Chiquita Brooks-LaSure. "Today, South Dakota becomes the 39th state along with D.C. in adopting the ACA’s Medicaid expansion. We urge the more than 52,000 newly eligible South Dakotans to apply for coverage, and we look forward to working with more states to expand Medicaid and continue the historic improvements in getting people insured under the Biden-Harris Administration." [...] Medicaid, together with the Children’s Health Insurance Program (CHIP), remain the largest source of health care coverage in the U.S., connecting nearly 94 million individuals to a range of critical health services. If all remaining states were to expand their Medicaid programs under the Affordable Care Act (ACA), as many as 4 million more un- or under-insured individuals could enroll in high-quality, affordable health care coverage through Medicaid. Specifically, the number of Black adults eligible for Medicaid would be almost five times greater, and six times greater for Hispanic adults.
