When Blue Cross Blue Shield recently published research suggesting that hospitals use artificial intelligence tools to extract more money from insurers without providing additional care, people were mad. Amid growing concerns about AI, one glimmer of hope has been its potential to improve health — and yet, here it was: inflating health care costs without yielding any benefits.
As a doctor who has used the kinds of tools being criticized, I’m frustrated, too: We can document honestly and still wind up inflating hospital bills. This is because comorbidities function as an on-off switch with respect to billing, even though they affect patient care in nuanced ways.
