Two-thirds of all bankruptcies filed in the United States are tied to medical expenses. Researchers estimate that 1 of every 6 emergency room visits and inpatient hospital stays involve care from at least one out-of-network provider, resulting in surprise medi-cal bills. Studies have shown that in the period from 2010-2016, more than 39% of emergency department visits to in-network hospitals resulted in an out-of-network bill, increasing to 42.8% in 2016. During the same period, the average amount of a surprise medical bill also increased from $220 to $628.
