This brief, published in October 2011, discusses the promise and practical realities of implementing the Affordable Care Act (ACA) in terms of maintaining health coverage during life transitions. The authors provide a detailed set of recommendations for state and federal policymakers on how to ensure seamless health coverage under the ACA for individuals and families who lose health insurance due to work or life transitions. The ACA aims to ensure that people can still have affordable health coverage if they lose a job, get divorced, retire early, or graduate from school and are no longer covered on a parent's plan. The authors emphasize the importance of addressing the issue of uninsurance caused by work or life transitions and provide policy recommendations to achieve this goal.
