Artificial intelligence-assisted hospital billing may have contributed to an estimated $942 million (£712.29 million) increase in healthcare spending as more patients were classified as medically complex without a corresponding rise in treatment, according to a new analysis from the Blue Cross Blue Shield Association.
The research found that hospitals increasingly placed patients into higher-reimbursement categories in 2024 and 2025 than in 2023, often after documenting additional or 'secondary' diagnoses.
