Read the full guide →Does the FDA Approve AI-Powered Medical Devices?
Yes, the FDA reviews and authorizes AI-powered medical devices before they can be legally marketed in the U.S., using regulatory pathways similar to those for other medical devices, though the specific process — clearance, approval, or another pathway — depends on the device's risk classification and intended use rather than being identical for every AI product.
How Does the FDA Evaluate AI Software That Continues to Learn After Approval?
The FDA has been developing specific regulatory approaches for AI-based medical software that may change or continue learning after initial authorization, including frameworks intended to allow certain pre-specified types of modifications without requiring an entirely new review for every update, reflecting an evolving effort to regulate technology that behaves differently from traditional.
How Many AI Medical Devices Has the FDA Authorized?
The FDA has authorized several hundred AI- and machine learning-enabled medical devices to date, a number that has grown substantially over recent years and continues to increase, though the exact current count changes frequently as new devices are authorized, so checking the FDA's own regularly updated public list is the most reliable way to get a precise, current figure.
What Happens If an FDA-Approved AI Medical Device Is Later Found to Be Unsafe?
If an FDA-authorized AI medical device is later found to raise safety concerns, the FDA can take a range of actions depending on severity, including requiring corrective actions, issuing safety communications, mandating labeling changes, or in serious cases, requesting or ordering a recall, as part of its ongoing post-market surveillance responsibilities that continue after a device's initial.
What Is the Difference Between FDA Clearance and FDA Approval for AI Tools?
FDA clearance and FDA approval refer to different regulatory pathways with different evidentiary standards, generally applied based on a device's risk classification — clearance is commonly used for moderate-risk devices shown to be substantially similar to an already-legally-marketed device, while approval generally applies to higher-risk devices requiring more extensive evidence, and AI tools.
