I fail to see how the amount uncollected could go up from this interaction. Before, uninsured people would have to pay full price (hospitals tend to charge uninsured people more), now they only have to pay a deductible...
Though chances are any time the uninsured rate goes down, the default rates of insured people will go up. Newer insured people are less likely to have their finances intact after all. So anything that lowers the uninsured rate will cause this issue I suppose
Maybe new healthcare revisions should offer FDIC-style insurance for deductibles for hospitals. Wouldn't want people refused from hospitals despite having insurance.
