Yahoo Finance says Blue Cross Blue Shield found hospitals’ use of AI coding tools was the biggest factor behind nearly $1 billion in added healthcare spending over two years. The tools flag extra secondary diagnoses that raise billing categories without changing care. According to Yahoo Finance, insurers say the higher payments are passed on to consumers; premiums rose 20% in 2026, with another double-digit increase proposed for 2027.
