Health care spending grew at a faster rate in 2018

Americans spent $3.65 trillion on health care in 2018 — 4.6% more than the year before. That growth also was higher than the 4.2% rate from 2017, according to revised figures from independent federal actuaries.

Between the lines: U.S. health care spending climbed again not because people went to the doctor or hospital more frequently, but because the industry charged higher prices. And private health insurers didn't do a particularly good job negotiating lower rates.

TeamHealth sent thousands of surprise medical bills in 2017

Physician staffing firm TeamHealth sent thousands of surprise medical bills to patients in 2017, a strategy used to obtain higher payment rates from insurers, according to a letter from the company sent to a group of senators in March, which was obtained by Axios.

Why it matters: These bills can be unaffordable for the small portion of TeamHealth's patients who receive them, and the subsequently high in-network rates raise premiums for everyone.
