what is the idea behind a single payer system of health insurance
Single-payer healthcare Single-payer healthcare is a healthcare system financed by taxes that covers the costs of essential healthcare for all residents, with costs covered by a single public system (hence 'single-payer').[1][2] Alternatively, a multi-payer healthcare system is one in which private, qualified individuals or their employers pay for health insurance with various limits on healthcare coverage via multiple private or public sources.[3][4]
Patient Protection and Affordable Care Act The ACA's major provisions came into force in 2014. By 2016, the uninsured share of the population had roughly halved, with estimates ranging from 20â€“24 million additional people covered during 2016.[6][7] The increased coverage was due, roughly equally, to an expansion of Medicaid eligibility and to major changes to individual insurance markets. Both involved new spending, funded through a combination of new taxes and cuts to Medicare provider rates and Medicare Advantage. Several Congressional Budget Office reports said that overall these provisions reduced the budget deficit, and that repealing the ACA would increase the deficit.[8][9] The law also enacted a host of delivery system reforms intended to constrain healthcare costs and improve quality. After the law went into effect, increases in overall healthcare spending slowed, including premiums for employer-based insurance plans.[10]
