Key metric: Healthcare Coverage Rate

As a social scientist, I analyze that the Republican efforts to modify the Affordable Care Act (ACA) through legislative and regulatory changes are likely to have significant impacts on healthcare coverage in the United States. The new law and CMS rule are expected to reduce enrollment in ACA plans by making it more difficult to enroll and maintain coverage, increasing costs for enrollees, and restricting eligibility for certain groups. This is projected to lead to millions more uninsured Americans over the next decade, reversing gains made since the ACA's implementation. The changes also risk destabilizing the ACA marketplaces by potentially driving out healthier enrollees, which could lead to premium increases and insurer exits. These actions, while less overt than previous repeal attempts, represent a significant shift in healthcare policy that could have long-lasting effects on access to health insurance and healthcare services for many Americans.
