The FDA employs a risk-based approach to classify SaMD based on its intended use and risk profile to the patient. SaMD classification relies heavily on understanding – the intended purpose of the software and the potential impact on the patient or user if the software fails. The 3 FDA Classifications for SaMD The FDA classifies SaMD into three categories – Class I, Class II, and Class III, based on intended use and level of risk to the patient. Below, we’ll explore each classification, its criteria, and examples to help you understand the differences.    1. Class I SaMD – Low Risk Class I SaMD encompasses devices with the lowest risk to patients. These are typically tools that support general health management without making critical medical decisions.    Criteria for Class I:  Examples of Class I SaMD:  Regulatory Requirements:  Most Class I SaMD products are exempt from premarket notification (510 [k]). However, developers must still adhere to basic FDA regulations, including proper labeling and quality system requirements.  2. Class II SaMD – Moderate Risk  Most SaMD falls into Class II, as this category includes software that supports clinical decision-making but does not directly intervene or treat patients.    Criteria for Class II:  Examples of Class II SaMD:  Regulatory Requirements:  Class II products require premarket notification in the form of a 510(k) submission. This demonstrates that the software is substantially equivalent to an already approved device on the market, ensuring its safety and effectiveness.  3. Class III SaMD – High Risk  Class III SaMD represents the highest risk level. These are devices that provide life-saving or life-sustaining functionalities and significantly influence patient outcomes. The FDA requires rigorous testing and approval for these products.    Criteria for Class III:  Examples of Class III SaMD:  Regulatory Requirements:  Class III products must undergo the FDA’s Premarket Approval (PMA) process, the most stringent regulatory pathway. Manufacturers must provide detailed clinical data to demonstrate the software’s safety, efficacy, and reliability.  “You might like to explore: FDA Penetration Testing: Why It’s Vital for 510(k) Submission?“   Latest Penetration Testing Report Download SaMD Regulatory Overview: Key Steps for FDA Approval If you’re developing SaMD, here’s how to successfully navigate the FDA approval process: Determine Classification: Research your product’s intended use and compare it to FDA guidelines to identify its classification.
