  • Implications of Reduced Federal Medicaid Funds: How Could States Fill the Funding Gap?

    Issue Brief

    In this analysis, we present three scenarios of reductions in federal Medicaid spending and examine fiscal implications if states fill these financing gaps to maintain their programs and if all reductions are assumed to be in full effect in FFY 2015 (the most recent year for which Medicaid spending data is available). To fill these gaps in financing and maintain current Medicaid programs, we assume states will increase state spending for Medicaid by increasing state taxes or reducing education spending. This analysis is unlike the CBO estimate, which makes projections and accounts for changes in policy, state responses to make changes to Medicaid programs, and reductions in coverage.

  • Data Note: What if Per Enrollee Medicaid Spending Growth Had Been Limited to CPI-M from 2001-2011?

    Issue Brief

    Congress is currently debating the American Health Care Act (AHCA), which would repeal and replace the Affordable Care Act (ACA) and also make substantial changes to the structure and financing of Medicaid. Among other provisions, the AHCA would use a per capita cap policy to cap federal funds to states for Medicaid. This data note examines what the implications of tying per enrollee growth to CPI-M would have been for the 2001-2011 period for federal spending nationally and state-by-state by major enrollment group. This analysis is meant to illustrate how actual spending compares to spending limits that would have been in place if growth rates had been limited to CPI-M, similar to the limits proposed by the AHCA.
