Medicaid Expansion Is Producing Large Gains in Health Coverage and Saving States Money

In the short time since states have been able to expand Medicaid to low-income adults under health reform, a clear divide has emerged between states that have expanded Medicaid and those that have not. Since the major coverage provisions of the ACA took effect in 2014, insurance coverage rates have improved across the country, but the gains are far greater in the states that have expanded Medicaid. As a result, hospitals in expansion states are treating fewer uninsured patients, and the amount of uncompensated care they are providing is declining steeply. Moreover, contrary to critics' claims that Medicaid expansion is financially unsustainable for states, there is increasing evidence that expansion has saved states money, and these savings are expected to grow over time.
