What Americans most fear about medical care costs

Unexpected medical bills top the list of health care costs Americans are afraid they will not be able to afford, with 4 in 10 people saying they had received a surprisingly large invoice within the past year, according to a new poll.

The Kaiser Family Foundation poll found that 67 percent of people worry about unexpected medical bills, more than they dread insurance deductibles, prescription drug costs or the basic staples of life: rent, food and gas. (Kaiser Health News is an editorially independent program of the foundation.)

Thirty-nine percent of insured adults under age 65 said they had received a medical bill within the previous 12 months that they’d figured would be covered or that was higher than they anticipated. Half of those people said the bill was less than $500, but nearly 1 in 8 said they were on the hook for $2,000 or more.

A quarter of people who said they received a surprisingly large bill attributed it to a doctor, hospital or other provider that was not in their insurance network. Such providers often will not accept the amount an insurer thinks a procedure or test should cost, and they bill the patient for the difference. That practice, known as balance billing, is one of the most common types of outsize charges that KHN and NPR profile in the “Bill of the Month” series.

Another poll recently conducted by NORC at the University of Chicago, a research group, found similar numbers of people had received a surprise bill. The most common charges were for a physician’s service or a lab test.

Plenty of blame to go around

Once again, the Kaiser poll found that a majority of the public — regardless of political party — does not want insurers to be allowed to deny coverage or charge higher premiums because of someone’s medical history or health status. Both practices were standard in the health insurance industry until they were outlawed by the Affordable Care Act in 2010.
