AI tools generated nearly $1 billion in extra costs, Blue Cross insurers say

Key Points:

• A Blue Cross Blue Shield Association (BCBSA) study found that AI tools have increased health spending for insurers by nearly $1 billion between 2024 and 2025, primarily due to providers billing for more severe patient care.
• Providers used AI technology, such as scanning patient records and ambient scribes, to identify secondary conditions, leading to $653 million in additional costs from billing for these conditions alone.
• The study highlighted that more complex documented care during patient visits results in higher payments by insurers, but this increase in billed severity does not always correspond to increased treatment, indicating AI may be identifying more billable conditions rather than sicker patients.
• For major bowel surgeries, secondary conditions like partial intestinal blockages and acid overload increased significantly, but treatments such as blood transfusions for anemia did not rise proportionally, suggesting a disconnect between diagnosis and actual patient care.
• The BCBSA study analyzed inpatient billing data across its network of 31 independent insurers covering over 100 million people, focusing on hospital admissions and medical facility care.
