The document discusses how the Affordable Care Act (ACA) improved insurance coverage and access to care for children with pre-existing conditions. It finds that after the ACA, adolescents (12-17 years) with chronic health conditions were less likely to be uninsured or delay/forgo care due to cost. However, similar improvements were not seen for younger children. This represents an early estimate as the 2010 ACA mandate lacked community rating provisions to limit premium costs for families of chronically ill children.
