HCCI data was cited in an NPR/KHN Bill of the Month story.
From the article:
"Hospitals generally charge uninsured people much more than they charge people who have insurance. A 2017 report from the Health Care Cost Institute showed that the average negotiated price of an acute mental health admission was $9,293 for a commercially insured patient who stayed, on average, for a week. That's less than half of Feilen's bill."
