Hospitals' AI coding tools added $942 million to Blue Cross Blue Shield plans' inpatient costs from early 2023 through 2025 without matching changes in treatment, the Blue Cross Blue Shield Association said Sept. 24.

The association found that the share of inpatient claims coded as medically complex rose from about 37% to about 40% while hospitals with the most complex coding delivered similar or less intensive care, Fierce Healthcare reported. The American Hospital Association said inpatients are older and sicker. The same day, Centers for Medicare & Medicaid Services Administrator Dr. Mehmet Oz told an Oracle conference in Orlando that AI will be "inflationary" in the short term because it will "turbocharge" billing systems. A multicenter study in npj Digital Medicine found that junior clinicians identified 15.8% of hallucinations in GPT-4o outputs.

Two announcements this week aimed AI at cancer care. The Cigna Group and OpenAI said their first joint tools will serve oncology nurses and case managers, and Oracle Health announced an oncology electronic health record with AI agents but gave no launch date. Cancer was the most-searched disease area on Medscape's AI search tool in all nine countries the company studied in the first half of 2026, according to Medscape data published through Stacker.
