The nation's top health official implored states to do more to keep lower-income residents enrolled in Medicaid, as the Biden administration released figures Friday confirming that many who had health coverage during the coronavirus pandemic are now losing it. In 18 states that began a post-pandemic review of their Medicaid rolls in April, health coverage was continued for about 1 million recipients and terminated for 715,000. Of those dropped, 4 in 5 were for procedural reasons, according to newly released data from the federal Centers for Medicare and Medicaid Services.
