Issue Brief 16-40
August 26, 2016

For states that have implemented the Medicaid expansion under the Affordable Care Act (ACA), the federal government pays 100% of the cost for covering newly eligible individuals through calendar year (CY) 2016. CY 2017 marks the first year that states will share in the cost. The federal match declines to 95% and continues to phase down each year until it reaches 90% in CY 2020.
