GoKawiilBCBSA says AI-assisted hospital coding added $942 million in costs since 2023
Blue Cross Blue Shield Association estimates that hospitals' use of AI-assisted medical coding added nearly $942 million in costs to its health plans between 2023 and 2025. The group says much of the increase stems from AI identifying secondary diagnoses, often based on single lab values, that push patients into higher-paying billing categories. Health economist Christopher Whaley notes AI is making it easier to capture existing billing incentives, though the added diagnoses are not necessarily inappropriate.
