Jack Hadley, senior health services researcher at George Mason University in Fairfax, Va., pointed out that uninsured people are charged as much as two-thirds more than what insured people are charged because insurers are able to negotiate prices.
His research has found that privately insured individuals don't end up paying higher premiums to make up for the uninsured because hospitals that serve lower-income families don't have a lot of patients with insurance. He said the government pays about 75% of those unpaid hospital bills either by direct payment or through a disproportionate payment of Medicaid.
