Writing · Concrete actor (FDA), event (final guidance), date (Dec 2024), and measurable shift (faster update cycles) are strong. Active voice is used well.

California SB 1120 bars insurers from AI-only medical necessity denials, and Texas SB 1188 requires practitioners to disclose AI use to patients. Indicates a fragmented state compliance map that multistate networks must track alongside federal requirements.

Judge · Multiple sources confirm California SB 1120 and other states require human review for AI-based denials, creating a fragmented regulatory landscape.
