Since 2014, 32 states and the District of Columbia have expanded their Medicaid programs under the Affordable Care Act (ACA), thereby reducing the number of uninsured and improving access to care. Several studies have reported the substantial positive impact of the Medicaid expansion on overall hospital margins, mainly through a reduction in uncompensated care and an increase in Medicaid revenue. But using results from our 2017 hospital revenue cycle benchmarking survey, we have been able to take a deep dive into the impact of expansion on revenue cycle performance.
