Hospitals’ use of artificial intelligence tools as they submit insurance claims led to an additional $942 million in healthcare spending over a two-year period, according to an analysis by the Blue Cross Blue Shield Association.

The BCBSA analysis found “a sharp increase in patients being documented as having complex conditions,” but argued there is a “clear disconnect between [medical] coding and treatment,” as there’s “no evidence of corresponding change in care delivered.”

The New York Times pointed the analysis as just the latest sign that AI is contributing to an increase in healthcare costs. While battles between hospitals and insurers over treatments and payments are nothing new, the NYT said the use of AI on both sides seems to be making it worse.

Dr. Shiv Rao, founder of AI startup Abridge, acknowledged that the use of AI could lead to “a horrible dystopic future nobody wants to live in,” with “bots fighting bots, agents fighting agents.” But Rao said it might also reduce tensions and cut costs.

And the BCBSA’s senior vice president Luke Chalker resisted characterizing the situation as a battle, claiming, “It’s not a war. It’s a completely one-sided blood bath,” with insurers on the losing side.
