## Summary

Blue Cross Blue Shield Association estimates AI-assisted medical coding added nearly **$942 million** in costs for its health plans between **2023 and 2025** by shifting patients into higher-paying reimbursement categories. The increase aligns with **60% of hospitals adopting AI coding tools** during that period, per BCBSA’s analysis. While some diagnoses identified by AI are legitimate, critics like Brown University’s **Christopher Whaley** warn the tools may **accelerate billing incentives**, capturing minor or irrelevant conditions for higher payments without improving care.
