After his recent herniated-disk surgery, Peter Drier was ready for the $56,000 hospital charge, the $4,300 anesthesiologist bill, and the $133,000 fee for orthopedist. All were either in-network under his insurance or had been previously negotiated.

U.S. adults are likelier than those in other developed countries to struggle to pay their medical bills or to forgo care because of cost.
