In the United States, AI software used to make medical decisions is regulated as a medical device. Manufacturers submit evidence of safety and effectiveness, and the FDA authorises the product for a specific intended use before marketing.
Traditional devices are frozen once approved; AI can keep learning. The FDA is therefore developing a “predetermined change control” framework — manufacturers specify in advance what updates an AI may make and validate them through a structured quality process without a full new review each time.
Key FDA concepts
- Intended use defines what the AI may do
- Pre-market review validates safety and effectiveness
- Predetermined change control for evolving AI
- Post-market surveillance for real-world safety
