Health insurers paid nearly $1 billion more than usual for hospital care between 2024 and 2025 due to the widespread adoption of artificial intelligence tools in medical documentation, according to a study released by the Blue Cross Blue Shield Association. The organization found that AI systems scanning patient records and transcribing visits are identifying more billable secondary conditions, driving up hospital reimbursement payouts without a corresponding rise in patient sickness.
Rising Payouts Tied to AI Documentation
The study revealed that overall, more intense care contributed $942 million in costs to Blue Cross Blue Shield firms over the two-year period when compared to baseline data from 2023. Specifically, between 2024 and 2025, medical providers more frequently billed for secondary conditions—ailments stemming from a separate illness than the primary reason for a visit—which drove costs up by $653 million for BCBS companies during that timeframe.
The Blue Cross Blue Shield Association represents 31 independent health insurance companies and covers more than 100 million people. Its study focused specifically on billing in inpatient settings where patients were admitted to hospitals or medical facilities. When hospitals document more complex medical care, those patient visits command higher payouts under standard reimbursement models.
Identifying Billable Conditions Versus Sicker Patients
The financial surge is driven largely by how efficiently AI software reviews patient data. Hospitals utilize AI to scan through extensive current and historical patient records, as well as to operate ambient scribes that passively listen to conversations with patients to draft medical notes. While human reviewers might miss certain complications, AI systems consistently catch secondary diagnoses.
However, health officials point out a stark disconnect between the diagnoses logged by software and the actual medical treatments administered to patients. Luke Chalker, senior vice president of product and data science at BCBSA, noted that if patients were genuinely sicker, insurers would observe corresponding increases in medical treatments.

Dr. Razia Hashmi, vice president of clinical affairs at BCBSA, pointed to specific surgeries to illustrate the trend. For patients undergoing major bowel surgeries between the first quarter of 2023 and the fourth quarter of 2025, secondary conditions such as partial intestinal blockages and body acid overloads increased by 55% and 33%, respectively. Yet, when patients received diagnoses like anemia, standard treatments such as blood transfusions did not rise at a matching rate.
An AI Versus AI Industry Conflict
As hospitals deploy AI to maximize capture of secondary diagnoses and increase reimbursement complexity, health insurers are fighting back with their own automated systems. Insurance providers increasingly employ AI to scrutinize claims and question whether submitted treatments are medically necessary.
Other major health insurers, including Centene, have similarly noted that the widespread use of automated hospital tools has led to aggressive or inappropriate reimbursement payments. This growing dynamic creates an automated standoff between hospital documentation algorithms and insurer review algorithms, driving up compute consumption and administrative costs across the healthcare sector while potentially passing financial burdens down to consumers through higher insurance premiums.
