A Survival Guide to Surprise Medical Bills

How to spot errors, fight out-of-network charges and lessen the stress of health care debt

En español | What is Americans’ biggest financial concern about their health care? It isn’t insurance expenses or drug costs. It’s the specter of an unexpected bill. A 2018 Kaiser Family Foundation poll found that 67 percent of people worry that they won’t be able to afford a surprise medical bill — more than fear being unable to pay for prescription drugs, health insurance premiums or deductibles, or for staples such as food, rent, mortgage and gas.

That probably comes as little surprise to anyone who’s opened an envelope from a hospital or doctor’s office and found a three-, four- or five-figure bill for care they thought their health plan would cover. More than half of American adults have been on the receiving end of such bills, according to a 2018 study by the University of Chicago-based research institution NORC.

While some states have laws in place to shield consumers from surprise medical bills, there is no nationwide protection. That may soon change. Bipartisan groups in both the House and Senate, and the White House, have gotten behind efforts to restrict the chief cause of surprise bills: "balance billing," which occurs when patients are treated at medical facilities in their health plan's network but are seen, and charged, by out-of-network doctors.

In the meantime, though, many patients still face the stress of getting a big medical bill they didn't see coming.
