Translated with AI<\/i><\/p>\n

The evolution of digital health has blurred the lines between IT tools and Medical Devices. A key reference for navigating this landscape is the FDA guidance published on January 6, 2026,<\/strong> in its second update: \u201c<\/strong><\/span>Clinical Decision Support Software – Guidance for Industry and FDA Staff<\/strong><\/a>\u201d<\/strong>.<\/span><\/span><\/p>\n

The document clarifies when a Clinical Decision Support (CDS)<\/strong> software function is or is not regulated as a medical device – specifically as Software as a Medical Device (SaMD)<\/strong> – under Section 520(o)(1)(E) of the Federal Food, Drug, and Cosmetic Act (FD&C Act)<\/strong>.<\/p>\n

Compared to the 2022 version, the guidance provides additional examples and clarifications on the distinction between Device CDS<\/strong> and Non-Device CDS<\/strong>.<\/p>\n

What is Clinical Decision Support Software (CDS)?<\/strong><\/h3>\n

A CDS is a computer system that provides Health Care Professionals (HCPs), patients, or caregivers with information to support decisions about diagnosis, treatment, or management of diseases or medical conditions<\/strong>. This is achieved through alerts, patient-specific therapeutic suggestions, or data and image analysis. Examples range from hospital software flagging dangerous drug-drug interactions to mobile apps suggesting questions for a patient to ask their physician based on symptoms.<\/p>\n

However, not all CDS software intended for clinical decisions meets the statutory definition of a medical device subject to FDA oversight.<\/p>\n

Non-Device CDS: The Four Statutory Exclusion Criteria<\/strong><\/h3>\n

A CDS software function is not<\/strong> considered a medical device if it meets all four of the following exclusion criteria simultaneously:<\/p>\n

    \n
  1. No Analysis of Medical Images or Signals<\/strong>
    The software must not acquire, process, or analyze medical images or signals from In Vitro Diagnostic (IVD) devices or data acquisition systems (e.g., raw ECG waveforms).<\/li>\n
  2. Display or Analysis of Medical Information Only<\/strong>
    The function must be limited to displaying, analyzing, or printing medical information about a patient or other existing clinical information (e.g., peer-reviewed clinical studies, historical vital signs, or previously processed laboratory results).<\/li>\n
  3. Support for, Not Replacement of, Clinical Judgment<\/strong>
    The purpose must be solely to provide patient-specific recommendations for a disease or condition without replacing or directing the healthcare professional\u2019s judgment.<\/li>\n
  4. Independent Review by the Professional<\/strong>
    The software must provide sufficient information to allow HCP to independently review the basis for the recommendations, ensuring they do not rely primarily on the software\u2019s output to make a clinical decision.<\/li>\n<\/ol>\n

    When Software is Classified as a Medical Device (Device CDS)<\/strong><\/h3>\n

    Software falls under FDA regulation when its function involves higher risk or delegates the clinical decision-making process.<\/p>\n

    The 2026 guidance highlights key scenarios:<\/p>\n
