Hospitals' growing use of artificial intelligence tools when submitting insurance claims added an estimated $942 million to US healthcare spending over a two-year period, according to an analysis by the Blue Cross Blue Shield Association that is intensifying a simmering fight between hospitals and insurers over who profits from medical AI.
What the Analysis Found
The Blue Cross Blue Shield Association, the national alliance of Blue Cross and Blue Shield plans, reported what it called a sharp increase in patients being documented as having complex conditions — the kind of diagnoses that justify higher reimbursement rates. For more context on this story, see our ongoing breaking AI news.
The association argued there is a clear disconnect between medical coding and treatment, saying it found no evidence of a corresponding change in the care actually delivered to patients. In other words, records have grown more complicated and expensive even as treatment has stayed the same.
The New York Times, which reported on the analysis, described it as the latest sign that AI is contributing to rising healthcare costs in the United States. Battles between hospitals and insurers over treatments and payments are nothing new, but the Times noted that the deployment of AI on both sides of the negotiating table appears to be making the conflict worse rather than resolving it.
The mechanism at the center of the dispute is medical coding — the system that translates every diagnosis and procedure into standardized billing categories. Documentation of complex, expensive-to-treat conditions generally means higher payments, so the accuracy and completeness of coding has a direct financial value. When AI tools make it effortless to capture every possible condition a patient might have, the boundary between thorough record-keeping and revenue optimization becomes genuinely hard to see.
'A Completely One-Sided Blood Bath'
Industry executives are not shy about the stakes. Luke Chalker, the Blue Cross Blue Shield Association's senior vice president, resisted framing the situation as an even contest between two AI-equipped camps.
"It's not a war. It's a completely one-sided blood bath," Chalker said, positioning insurers as the losing side in a contest over documentation and payment.
The comment reflects a growing anxiety among payers: ambient AI scribes and automated coding assistants can help hospitals capture every billable detail of a patient visit, while insurers have struggled to audit the flood of increasingly complex claims at the same speed.
The View From the Hospital Side
Not everyone in the AI health community accepts the insurers' characterization. Dr. Shiv Rao, founder of AI documentation startup Abridge, acknowledged that the technology could produce what he called a horrible dystopic future nobody wants to live in, with "bots fighting bots, agents fighting agents."
But Rao argued the same automation could cut the other way — reducing tensions between hospitals and payers, lowering administrative overhead, and ultimately trimming costs rather than inflating them. That optimism is shared by many health systems, which say AI scribes reduce physician burnout and improve the completeness of medical records.
Both things can be true at once. More complete documentation is better medicine and better billing, and the line between the two is exactly where the money fight now sits.
AI Is Now on Both Sides of the Claim
The healthcare industry has become one of the fastest adopters of generative AI. Hospitals use ambient listening tools to draft clinical notes, coding software to translate those notes into billing codes, and AI assistants to appeal denied claims. Insurers, meanwhile, deploy algorithms to review claims, flag anomalies, and contest charges they view as inflated.
When both sides automate, each upgrade on one side triggers a counter-upgrade on the other — an arms race that lands on premium payers and patients. The BCBSA analysis suggests the first measurable result of that race is nearly a billion dollars in added spending over just two years, from the hospital side of the ledger alone.
Why the Numbers Matter Beyond Healthcare
The dispute is an early case study in a problem that will follow AI into every billing-driven industry: when the cost of producing detailed paperwork collapses to nearly zero, the paperwork multiplies, and so do the disputes over it.
For regulators, the BCBSA findings raise questions about whether coding practices enabled by AI tools should face new scrutiny, particularly where diagnoses grow more complex without any documented change in care. For hospitals and AI vendors, the analysis is a warning that revenue gains tied to automated documentation may attract audits, litigation, and public backlash.
For now, neither hospitals nor insurers show any sign of slowing their AI adoption. The nine-figure question hanging over US healthcare is whether the technology will eventually automate its way to cheaper administration — or whether it will simply teach both sides to fight harder over the same claims.
