Federal funding ran out at midnight on Oct. 1, after Congress failed to pass even a stopgap budget while negotiations continued. The stalemate centers largely on health coverage, with Democrats and Republicans clashing over the Affordable Care Act and Medicaid cuts. For example, some community health centers would be at risk of closure as their federal funding dries up. But disease surveillance, support from the Centers for Disease Control and Prevention to local and state health departments, and funding for health programs will all be hampered, based on federal health agencies’ contingency plans. Without the extended subsidies, health insurers are warning of double-digit premium hikes for millions of enrollees.
