We can estimate the impact of the AHCA per-capita cap on the pre-Obamacare Medicaid population by using data from CMS, which expects that the federal government will spend approximately $6.7 trillion on the legacy Medicaid program from 2017 to 2026. If we apply CBO’s estimate of future medical inflation to the AHCA, we get to a spending reduction of $107 billion from 2017 to 2026. $107 billion represents 13% of the CBO’s estimate of the AHCA’s Medicaid spending cuts. More importantly, it represents a paltry 1.6% of total federal spending on the legacy Medicaid program over that time frame.
