Policy for device software functions and mobile medical applications
The Food and Drug Administration (FDA) recognizes the extensive variety of actual and potential functions of software applications (apps) and mobile apps, the rapid pace of innovation, and their potential benefits and risks to public health. The FDA is issuing this guidance document to inform manufacturers, distributors, and other entities about how the FDA intends to apply its regulatory authorities to select software applications intended for use on mobile platforms (mobile applications or “mobile apps”) or on general-purpose computing platforms. Given the rapid expansion and broad applicability of software functions deployed on mobile or other general-purpose computing platforms, the FDA is issuing this guidance document to clarify the subset of software functions to which the FDA intends to apply its authority.
FDA refers to software functions that are device functions as “device software functions.” Device software functions may include “Software as a Medical Device (SaMD)” and “Software in a Medical Device (SiMD)”. Software functions that meet the definition of a device may be deployed on mobile platforms, other general-purpose computing platforms, or in the function or control of a hardware device. If a software function that meets the definition of a device is deployed on a mobile platform, it may be referred to as a “mobile medical app.” The policies described in this guidance are independent of the platform on which they might run, are function-specific, and apply across platforms. Therefore, the policies described using terms such as “mobile medical apps,” “mobile medical app manufacturers,” “device software functions,” and “device software function manufacturers” are not specific to whether the the function is deployed on a mobile platform or other general purpose-computing platform.
Many software functions are not medical devices (meaning such software functions do not meet the definition of a device under section 201(h) of the Federal Food, Drug, and Cosmetic Act (FD&C Act)), and FDA does not regulate them as devices. Some software functions may meet the definition of a medical device, but because they pose a lower risk to the public, FDA intends to exercise enforcement discretion over these devices (meaning it will not enforce requirements under the FD&C Act).
Consistent with the FDA’s existing oversight approach that considers functionality of the software rather than platform, the FDA intends to apply its regulatory oversight to only those software functions that are medical devices and whose functionality could pose a risk to a patient’s safety if the device were to not function as intended.
FDA is issuing this guidance to provide clarity and predictability for software manufacturers. This document has been updated to be consistent with section 3060(a) of the 21st Century Cures Act, which amended section 520 of the FD&C Act, removing certain software functions from the definition of device in section 201(h) of the FD&C Act, and the guidance document entitled “Medical Device Data Systems, Medical Image Storage Devices, and Medical Image Communications Devices” originally issued on February 9, 2015. Examples of mobile apps and software on the FDA web site (that were added after September 25, 2013) were incorporated into the appropriate appendices of this document for consistency.
For the current edition of the FDA-recognized standard(s) referenced in this document, see the FDA Recognized Consensus Standards Database. For more information regarding use of consensus standards in regulatory submissions, please refer to the FDA guidance titled “Appropriate Use of Voluntary Consensus Standards in Premarket Submissions for Medical Devices” and “Standards Development and the Use of Standards in Regulatory Submissions Reviewed in the Center for Biologics Evaluation and Research”.
FDA's guidance documents, including this guidance, do not establish legally enforceable responsibilities. Instead, guidances describe the Agency’s current thinking on a topic and should be viewed only as recommendations, unless specific regulatory or statutory requirements are cited. The use of the word should in Agency guidance means that something is suggested or recommended, but not required.
As mobile platforms become more user friendly, computationally powerful, and readily available, innovators have begun to develop mobile apps of increasing complexity to leverage the portability mobile platforms can offer. Some of these new software functions are specifically targeted to assisting individuals in their own health and wellness management. Other software functions are targeted to health care providers as tools to improve and facilitate the delivery of patient care.
In 1989, FDA prepared a general policy statement on how it planned to determine whether a computer-based product and/or software-based product is a device, and, if so, how the FDA intended to regulate it. The document, “FDA Policy for the Regulation of Computer Products,” became known as the “Draft Software Policy.” After 1989, however, the use of computer and software products as medical devices grew exponentially and the types of products diversified and grew more complex (and that trend has continued). As a result, the FDA determined that the draft policy did not adequately address all of the issues related to the regulation of all medical devices containing software. Therefore, in 2005, the Draft Software Policy was withdrawn.
Although the FDA has not issued an overarching software policy, the Agency has formally classified certain types of software applications that meet the definition of a device and, through classification, identified specific regulatory requirements that apply to these devices and their manufacturers. These software devices include products that feature one or more software components, parts, or accessories, as well as devices that are composed solely of software.
The FDA has previously clarified that when a software application is used to analyze medical device data, it has traditionally been regulated as an accessory to a medical device or as medical device software. In 2014, the International Medical Device Regulators Forum established globally harmonized vocabulary for such software applications and defined the term “Software as a Medical Device (SaMD)”.
As is the case with traditional medical devices, certain software functions that are device functions (referred to in this document as ‘device software functions’) can pose potential risks to public health. Moreover, certain device software functions may pose risks that are unique to the characteristics of the platform on which the software function is run. For example, the interpretation of radiological images on a mobile device could be adversely affected by the smaller screen size, lower contrast ratio, and uncontrolled ambient light of the mobile platform. FDA intends to take these risks into account in assessing the appropriate regulatory oversight for these products.
This guidance clarifies and outlines the FDA’s current thinking. The Agency will continue to evaluate the potential impact these technologies might have on improving health care, reducing potential medical mistakes, and protecting patients.
For purposes of this guidance, “mobile platforms” are defined as commercial off-the-shelf (COTS) computing platforms, with or without wireless connectivity, that are handheld in nature. Examples of these mobile platforms include mobile computers such as smart phones, tablet computers, or other portable computers.
Mobile Application (Mobile App)
For purposes of this guidance, a mobile application or “mobile app” is defined as a software application that can be executed (run) on a mobile platform (i.e., a handheld commercial off-the-shelf computing platform, with or without wireless connectivity), or a web-based software application that is tailored to a mobile platform but is executed on a server.
Mobile Medical Application (Mobile Medical App)
For purposes of this guidance, a “mobile medical app” is a mobile app that incorporates device software functionality that meets the definition of device in section 201(h) of the FD&C Act ; and either is intended:
- to be used as an accessory to a regulated medical device; or
- to transform a mobile platform into a regulated medical device.
The intended use of a mobile app determines whether it meets the definition of a “device.” As stated in 21 CFR 801.4, intended use may be shown by labeling claims, advertising materials, or oral or written statements by manufacturers or their representatives. When the intended use of a mobile app is for the diagnosis of disease or other conditions, or the cure, mitigation, treatment, or prevention of disease, or is intended to affect the structure or any function of the body of man, the mobile app is a device under section 201(h) of the FD&C Act if it is not a software function excluded from the device definition by section 520(o) of the FD&C Act.
One example is a mobile app that makes a light emitting diode (LED) operate. If the manufacturer intends the system to illuminate objects generally (i.e., without a specific medical device intended use), the mobile app would not be considered a medical device. If, however, through marketing, labeling, and the circumstances surrounding the distribution, the mobile app is promoted by the manufacturer for use as a light source for doctors to examine patients, then the intended use of the light source would be similar to a conventional device such as an ophthalmoscope.
In general, if a software function is intended for use in performing a medical device function (i.e. for diagnosis of disease or other conditions, or the cure, mitigation, treatment, or prevention of disease) it is a medical device, regardless of the platform on which it is run. For example, mobile apps intended to run on smart phones to analyze and interpret EKG waveforms to detect heart function irregularities would be considered similar to software running on a desktop computer that serves the same function, which is regulated under 21 CFR 870.2340 (“Electrocardiograph”). FDA’s oversight approach to software functions is focused on their functionality, just as we focus on the functionality of conventional devices. Our oversight is not determined by the platform. Under this guidance, FDA would not regulate the sale or general/conventional consumer use of smartphones or tablets. FDA’s oversight applies to software functions performing medical device functions, such as when a mobile medical app or software application transforms a mobile platform or a general purpose computing platform into a medical device. However, as previously noted, we intend to apply this oversight authority only to those software applications whose functionality could pose a risk to a patient’s safety if the software applications were to not function as intended.
Regulated Medical Device
For purposes of this guidance, a “regulated medical device” is defined as a product that meets the definition of device in section 201(h) of the FD&C Act and that has been cleared or approved by the FDA review of a premarket submission or otherwise classified by the FDA.
This definition can include novel devices, whether or not on a mobile platform, that the FDA will clear or approve by the review of a premarket submission or otherwise classify. Examples of regulated medical devices are identified in Appendix D.
Mobile Medical App Manufacturer
For purposes of this guidance, a “mobile medical app manufacturer” is any person or entity that manufactures mobile medical apps in accordance with the definitions of manufacturer in 21 CFR Parts 803, 806, 807, and 820. A mobile medical app manufacturer may include anyone who initiates specifications, designs, labels, or creates a software system or application for a regulated medical device in whole or from multiple software components. This term does not include persons who exclusively distribute mobile medical apps without engaging in manufacturing functions; examples of such distributors may include owners and operators of “Google Play,” “iTunes App Store,” and “BlackBerry App World.” Examples of mobile medical app manufacturers include any person or entity that:
Creates, designs, develops, labels, re-labels, remanufactures, modifies, or creates a mobile medical app software system from multiple components. This could include a person or entity that creates a mobile medical app by COTS software components and markets the product to perform as a mobile medical app;
Initiates specifications or requirements for mobile medical apps or procures product development/manufacturing services from other individuals or entities (second party) for subsequent commercial distribution. For example, when a “developer” (i.e., an entity that provides engineering, design, and development services) creates a mobile medical app from the specifications that were initiated by the “author,” the “author” who initiated and developed specifications for the mobile medical app is considered a “manufacturer” of the mobile medical app under 21 CFR 803.3. For purposes of this guidance, manufacturers of a mobile medical app would include persons or entities who are the creators of the original idea (initial specifications) for a mobile medical app, unless another entity assumes all responsibility for manufacturing and distributing the mobile medical app, in which case that other entity would be the “manufacturer”. Software “developers” of a mobile medical app that are only responsible for performing design and development activities to transform the author’s specifications into a mobile medical app would not constitute manufacturers, and instead the author would be considered the manufacturer;
Creates a mobile medical app and hardware attachments for a mobile platform that are intended to be used as a medical device by any combination of the mobile medical app, hardware attachments, and the mobile platform;
Creates a mobile medical app or a software system that provides users access to the medical device function through a website subscription, software as a service, or other similar means.
In contrast, the following are examples of persons or entities that are NOT considered to be mobile medical app manufacturers (i.e., persons not within the definition of manufacturer in 21 CFR Parts 803, 806, 807, and 820). Because they are not manufacturers, none of the persons or entities in these examples would have to register their establishments, list their products with the FDA, or submit a premarket application:
Manufacturers or distributors of mobile platforms who solely distribute or market their platform and do not intend (by marketing claims – e.g., labeling claims or advertising material) the platform to be used for medical device functions. When mobile medical apps are run on a mobile platform, the mobile platform is treated as a component of the mobile medical app’s intended use. Therefore the mobile platform manufacturer is exempt from the Quality System regulation and registration and listing requirements. For example, if it is possible to run mobile medical apps on BrandNamePhone but BrandNamePhone is not marketed by BrandNameCompany as intended for use as a medical device, then BrandNameCompany would not be considered a mobile medical app manufacturer or a medical device manufacturer. Also, in this example, the BrandName Phone sold to consumers would not be regulated by FDA as a medical device. FDA does not consider entities that exclusively distribute mobile medical apps, such as the owners and operators of the “iTunes App Store” or the “Android Market,” to be medical device manufacturers. FDA also does not consider mobile platform manufacturers to be medical device manufacturer just because their mobile platform could be used to run a mobile medical app regulated by FDA.
Third parties who solely provide market access to mobile medical apps (i.e. solely distribute mobile apps), but do not engage in any manufacturing functions as defined in 21 CFR Parts 803, 806, 807, and 820. Examples of such third parties may include owners and operators that are only engaged in providing an online market place that allow mobile medical app manufacturers to commercially distribute their mobile medical apps. Specific examples of such online market places include “Google Play,” “iTunes Store,” and “BlackBerry App World”;
Providers of tools, services, or infrastructure used in the development, distribution, or use of a mobile medical app. Examples include providers of internet connectivity (i.e., internet service), providers of general-purpose computer or information technology, providers that host the web service for content or software application. Other examples of providers of tools, services, or infrastructure include customer support services, data center hosting services, cloud hosting services, application hosting services, wireless carriers, or providers of software development kits. However, a creator of a mobile medical app or a software system that provides users access to the medical device function through a website subscription, software as a service, or other similar means is considered a mobile medical app manufacturer;
Licensed practitioners, including physicians, dentists, and optometrists, who manufacture a mobile medical app or alter a mobile medical app solely for use in their professional practice and do not label or promote their mobile medical apps to be generally used by other licensed practitioners or other individuals. For example, if Dr. XYZ, a licensed practitioner, creates a mobile medical app called the “XYZ-recorder” that enables attaching an ECG electrode to a smartphone, and provides the “XYZ-recorder” to his/her patient to use it to record the patient’s electrocardiographic readings for 24 hours, Dr. XYZ is not considered a mobile medical app manufacturer. If Dr. XYZ is in a group practice (including a telehealth network) and permits other physicians in the practice to provide the XYZ-recorder to their patients, Dr. XYZ is not considered a mobile medical apps manufacturer. However, if Dr. XYZ, the licensed practitioner, distributes the “XYZ-recorder” and, through labeling or promotion intends to make it generally available to or to be generally used by other physicians (or other specially qualified persons), Dr. XYZ would be considered a mobile medical app manufacturer;
Persons who manufacture mobile medical apps solely for use in research, teaching, or analysis and do not introduce such devices into commercial distribution. We note that while persons conducting research using mobile medical apps involving human subjects are exempt from registration and listing, they may instead be subject to investigational device exemption regulations.
This guidance explains the FDA’s intentions to focus its oversight on a subset of software functions. Mobile medical apps, as defined in Section III, include only those mobile apps that meet the definition of a device and either are intended:
- to be used as an accessory to a regulated medical device; or
- to transform a mobile platform into a regulated medical device.
Appendix A provides examples of software functions, some of which are mobile apps, that FDA does NOT consider to meet the definition of a device and, therefore, are NOT device software functions or mobile medical apps for the purposes of this guidance.
Section V.B and Appendix B provide examples of software functions, some of which are mobile apps, that MAY meet the definition of a device but for which the FDA intends to exercise enforcement discretion because they pose a low risk to patients.
This guidance does not address the approach for software that performs patient-specific analysis to aid or support clinical decision-making.
FDA’s policies regarding accessories to medical devices are not unique to device software functions and go beyond the scope of this guidance. Specifically this guidance does not address FDA’s general approach for accessories to medical devices.
If you are developing a software function that meets the definition of a device (such as a mobile medical app) with an entirely new intended use, we encourage you to contact FDA to discuss what regulatory requirements may apply.
Regulatory Approach for Device Software Functions
As described in this guidance, FDA intends to apply its regulatory oversight to only those software functions that are medical devices and whose functionality could pose a risk to a patient’s safety if the device were to not function as intended. This approach to overseeing device software functions is consistent with our existing approach to overseeing medical device functionality of a product and the risks it poses to patients regardless of the shape, size, or the platform. The FDA believes that this subset of device software functions poses the same or similar potential risks to the public health as currently regulated devices if they fail to function as intended.
The FDA strongly recommends that manufacturers of all software and mobile apps that may meet the definition of a device follow the Quality System regulation (that includes good manufacturing practices) in the design and development of their device software functions, and initiate prompt corrections to their devices, when appropriate, to prevent patient and user harm.
For device software functions, manufacturers must meet the requirements associated with the applicable device classification. If the device, on its own, falls within a medical device classification, its manufacturer is subject to the requirements associated with that classification. A device software function, like other devices, may be classified as class I (general controls), class II (special controls in addition to general controls), or class III (premarket approval).
A. Device software functions: Subset of software functions that are the focus of FDA’s regulatory oversight
Software functions may take a number of forms, but it is important to note that the FDA intends to apply its regulatory oversight to only the subset of software functions identified below and in Appendix C. These software functions can transform a general-purpose computing platform or mobile platform into a regulated medical device by using attachments, display screens, sensors, or other such methods. Regardless of the mechanism behind the transformation, FDA considers such software to be device software functions.
The following are software functions that FDA considers to be device software functions subject to regulatory oversight:
1. Software functions that are an extension of one or more medical devices by connecting to such device(s) for purposes of controlling the device(s) or analyzing medical device data.
Examples of software functions that control medical devices include: software that provides the ability to control inflation and deflation of a blood pressure cuff through a mobile platform and mobile apps that control the delivery of insulin on an insulin pump by transmitting control signals to the pumps from the mobile platform.
Device software functions of these types are considered accessories to the connected device and are required to comply with the controls applicable to that connected device. The FDA considers such device software functions to extend the intended use and functionality of the connected medical device. As a result, the device software function would be required to comply with the regulations applicable to the connected medical device in order to address any associated risks.
2. Software functions (typically, mobile apps) that transform the mobile platform into a regulated medical device by using attachments, display screens, or sensors or by including functionalities similar to those of currently regulated medical devices. Software functions that use attachments, display screens, sensors or other such similar components to transform a mobile platform into a regulated medical device are required to comply with the device classification associated with the transformed platform.
Examples of these types of software functions include: a software function that uses a mobile platform for medical device functions, such as attachment of a blood glucose strip reader to a mobile platform to function as a glucose meter; or attachment of electrocardiograph (ECG) electrodes to a mobile platform to measure, store, and display ECG signals; a software function that uses the built-in accelerometer on a mobile platform to collect motion information for monitoring sleep apnea; a software function that uses sensors (internal or external) on a mobile platform for creating electronic stethoscope function is considered to transform the mobile platform into an electronic stethoscope; manufacturers of such a mobile app are required to follow the requirements of 21 CFR 870.1875(b) (Electronic Stethoscope); and similarly a software function that displays radiological images for diagnosis transforms the mobile platform into a class II Picture Archiving and Communications System (PACS) under 21 CFR 892.2050.
The FDA has cleared several mobile medical apps with attachments to a mobile platform. Specifically, patient monitoring mobile apps that monitor a patient for heart rate variability from a signal produced by an electrocardiograph, vectorcardiograph, or blood pressure monitor are classified as cardiac monitoring software under 21 CFR 870.2300 (Cardiac monitor). Other mobile medical apps that use a hardware attachment or interface to a monitoring system that have been cleared include an automatic electronic blood pressure monitor under 21 CFR 870.1130 and a perinatal monitoring system under 21 CFR 884.2740.
3. Software functions that become a regulated medical device by performing patient-specific analysis and providing patient-specific diagnosis, or treatment recommendations. These types of functions are similar to or perform the same function as those types of software devices that have been previously cleared or approved.
Examples of software functions that perform sophisticated analysis or interpret data (electronically collected or manually entered) from another medical device include: software functions that use patient-specific parameters and calculate dosage or create a dosage plan for radiation therapy; Computer Aided Detection software (CAD) image processing software; and radiation therapy treatment planning software. We believe that these types of software present the same level of risk to patients regardless of the platform on which they run.
The FDA encourages manufacturers of such device software functions that perform patient-specific analysis to contact FDA to discuss what, if any, regulatory requirements may apply. For additional examples see Appendix C.
B. Software functions for which FDA intends to exercise enforcement discretion (meaning that FDA does not intend to enforce requirements under the FD&C Act)
FDA intends to exercise enforcement discretion for software functions that:
Help patients (i.e., users) self-manage their disease or conditions without providing specific treatment or treatment suggestions; or
Automate simple tasks for health care providers.
Some software functions in the above categories and listed below may be considered device software functions, and others might not. For these examples listed below that are devices, FDA intends to exercise enforcement discretion because they pose a low risk to patients.
The following examples represent software functions for which the FDA intends to exercise enforcement discretion:
Software functions that provide or facilitate supplemental clinical care, by coaching or prompting, to help patients manage their health in their daily environment – These are software functions that supplement professional clinical care by facilitating behavioral change or coaching patients with specific diseases or identifiable health conditions in their daily environment. Examples include:
Software functions that coach patients with conditions such as cardiovascular disease, hypertension, diabetes, or obesity, and promote strategies for maintaining a healthy weight, getting optimal nutrition, exercising and staying fit, managing salt intake, or adhering to pre-determined medication dosing schedules by simple prompting.
Software functions that provide easy access to information related to patients’ health conditions or treatments (beyond providing an electronic “copy” of a medical reference) – This includes software that provides contextually-relevant information to users by matching patient-specific information (e.g., diagnosis, treatments, allergies, signs, or symptoms) to reference information routinely used in clinical practice (e.g., practice guidelines) to facilitate a user’s assessment of a specific patient. Examples include:
Software functions that use a patient’s diagnosis to provide a clinician with best practice treatment guidelines for common illnesses or conditions such as influenza; or
Software functions that are drug-drug interaction or drug-allergy look-up tools.
Software functions that are specifically marketed to help patients communicate with healthcare providers by supplementing or augmenting the data or information by capturing an image for patients to convey to their healthcare providers about potential medical conditions – These products either pose little or no risk, or are the sole responsibility of the health care providers who have experience with them in medical applications. Examples include:
Apps specifically intended for medical uses that utilize the mobile device’s built-in camera or a connected camera for purposes of documenting or transmitting pictures (e.g., photos of a patient’s skin lesions or wounds) to supplement or augment what would otherwise be a verbal description in a consultation between health care providers or between health care providers and patients/caregivers.
Software functions that perform simple calculations routinely used in clinical practice – These are software functions that are intended to provide a convenient way for clinicians to perform various simple medical calculations taught in medical schools and are routinely used in clinical practice. This software is generally tailored for clinical use, but retains functionality that is similar to simple general-purpose tools such as paper charts, spread sheets, timers, or generic mathematical calculators. Examples of such general-purpose tools include medical calculators for:
- Body Mass Index (BMI);
- Total Body Water / Urea Volume of Distribution;
- Mean arterial pressure;
- Glascow Coma Scale score;
- APGAR score;
- NIH Stroke Scale; or
Delivery date estimator.
See Appendix B for additional examples for the above categories.
This guidance, including Appendix C and existing medical device regulatory classifications in Appendix D, is intended to assist manufacturers in determining if the software functionality meets the definition of a device and FDA’s expectations for that product. Additional information can be found in “Device Advice: Classify Your Medical Device”. This section describes in greater detail the regulatory requirements applicable to device software functions under this guidance (as described in Section V).
Manufacturers of device software functions are subject to the requirements described in the applicable device classification regulation below. Depending on the classification and the associated regulation for the device software function, manufacturers are required to follow associated controls established by the regulation.
In general, the associated controls for each class of device are outlined below.
Class I devices: General Controls, including:
- Establishment registration, and Medical Device listing (21 CFR Part 807);
- Quality System (QS) regulation (21 CFR Part 820);
- Labeling Requirements (21 CFR Part 801);
- Medical Device Reporting (21 CFR Part 803);
- Premarket Notification (21 CFR Part 807);
- Reporting Corrections and Removals (21 CFR Part 806); and
- Investigational Device Exemption (IDE) requirements for clinical studies of investigational devices (21 CFR Part 812).
Class II devices: General Controls (as described for Class I), Special Controls, and (for most Class II devices) Premarket Notification.
Class III devices: General Controls (as described for Class I), and Premarket Approval (21 CFR Part 814).
Appendix E provides a brief summary of the above requirements. Additional information is available at the FDA web site, under “Overview of Medical Device Regulation” and “How to Study and Market Your Device”.

Examples of Software Functions that are NOT Medical Devices
This Appendix provides a representative list of software functionalities to illustrate the types of software that could be used in a health care environment, in clinical care, or patient management, but are not considered medical devices. Because these software functions are not considered medical devices, FDA does not regulate them. The FDA understands that there may be other unique and innovative software functions that may not be covered in this list that may also constitute health care related software. This list is not exhaustive; it is only intended to provide clarity and assistance in identifying when a software function is not considered to be a medical device.
Specific examples of software functions that FDA does not consider to be devices and with no regulatory requirements under the current laws administered by FDA include:
Software functions that are intended to provide access to electronic “copies” (e.g., e-books, audio books) of medical textbooks or other reference materials with generic text search capabilities – These are not devices because the software is intended to be used as reference material and is not intended for use in the diagnosis of disease or other conditions, or in the cure, mitigation, treatment, or prevention of disease by facilitating a health professional’s assessment of a specific patient, replacing the judgment of clinical personnel, or performing any clinical assessment. Examples of these types of software functions include:
- Medical dictionaries;
- Electronic copies of medical textbooks or literature articles such as the Physician’s Desk Reference or Diagnostic and Statistical Manual of Mental Disorders (DSM);
- Library of clinical descriptions for diseases and conditions;
- Encyclopedia of first-aid or emergency care information;
- Medical abbreviations and definitions;
Translations of medical terms across multiple languages.
Software functions that are intended for health care providers to use as educational tools for medical training or to reinforce training previously received – These may have more functionality than providing an electronic copy of text (e.g., videos, interactive diagrams), but are not devices because they are intended generally for user education and are not intended for use in the diagnosis of disease or other conditions, or in the cure, mitigation, treatment, or prevention of disease by facilitating a health professional’s assessment of a specific patient, replacing the judgment of clinical personnel, or performing any clinical assessment. Examples of these types of software functions include:
- Medical flash cards with medical images, pictures, graphs, etc.;
- Question/Answer quiz apps;
- Interactive anatomy diagrams or videos;
- Surgical training videos;
- Medical board certification or recertification preparation apps;
Games that simulate various cardiac arrest scenarios to train health professionals in advanced CPR skills.
Software functions that are intended for general patient education and facilitate patient access to commonly used reference information – This software can be patient-specific (i.e., filters information to patient-specific characteristics), but is intended for increased patient awareness, education, and empowerment, and ultimately supports patient-centered health care. These functions are not devices because they are intended generally for patient education, and are not intended for use in the diagnosis of disease or other conditions, or in the cure, mitigation, treatment, or prevention of disease by aiding clinical decision-making (i.e., to facilitate a health professional’s assessment of a specific patient, replace the judgment of a health professional, or perform any clinical assessment). Examples include software functions that:
- Provide a portal for health care providers to distribute educational information (e.g., interactive diagrams, useful links, and resources) to their patients regarding their disease, condition, treatment, or up-coming procedure;
- Help guide patients to ask appropriate questions to their physician relevant to their particular disease, condition, or concern;
- Provide information about gluten-free food products or restaurants;
- Help match patients with potentially appropriate clinical trials and facilitate communication between the patient and clinical trial investigators;
- Provide tutorials or training videos on how to administer first-aid or CPR;
- Allow users to input pill shape, color, or imprint and displays pictures and names of pills that match this description;
- Find the closest medical facilities and doctors to the user’s location;
- Provide lists of emergency hotlines and physician/nurse advice lines;
Provide and compare costs of drugs and medical products at pharmacies in the user’s location.
Software functions that automate general office operations in a health care setting and are not intended for use in the diagnosis of disease or other conditions, or in the cure, mitigation, treatment, or prevention of disease. Examples include software functions that:
- Determine billing codes like ICD-9 (international statistical classification of diseases);
- Enable insurance claims data collection and processing and other apps that are similarly administrative in nature;
- Analyze insurance claims for fraud or abuse;
- Perform medical business accounting functions or track and trend billable hours and procedures;
- Generate reminders for scheduled medical appointments or blood donation appointments;
- Help patients track, review, and pay medical claims and bills online;
- Manage shifts for doctors;
- Manage or schedule hospital rooms or bed spaces;
- Provide wait times and electronic check-in for hospital emergency rooms and urgent care facilities;
- Allow health care providers or staff in health care settings to process payments (for example, using a HIPAA compliant app to process payments);
Track or perform patient satisfaction survey after an encounter or a clinical visit.
Software functions that are generic aids or general-purpose products – This software is not considered a device because it is not intended for use in the diagnosis of disease or other conditions, or in the cure, mitigation, treatment, or prevention of disease. Examples include software functions that:
- Use the mobile platform as a magnifying glass (but are not specifically intended for medical purposes );
- Use the mobile platform for recording audio, note-taking, replaying audio with amplification, or other similar functionalities;
- Allow patients or health care providers to interact through email, web-based platforms, video, or other communication mechanisms (but are not specifically intended for medical purposes);
- Provide maps and turn-by-turn directions to medical facilities;
Allow health care providers to communicate in a secure and protected method (for example using a HIPAA compliant app to send messages between health care providers in a hospital).
Software functions that are intended for individuals to log, record, track, evaluate, or make decisions or behavioral suggestions related to developing or maintaining general fitness, health or wellness, such as those that:
- Provide tools to promote or encourage healthy eating, exercise, weight loss, or other activities generally related to a healthy lifestyle or wellness;
- Provide dietary logs, calorie counters or make dietary suggestions;
- Provide meal planners and recipes;
- Track general daily activities or make exercise or posture suggestions;
- Track a normal baby’s sleeping and feeding habits;
- Actively monitor and trend exercise activity;
- Help healthy people track the quantity or quality of their normal sleep patterns;
- Provide and track scores from mind-challenging games or generic “brain age” tests;
- Provide daily motivational tips (e.g., via text or other types of messaging) to reduce stress and promote a positive mental outlook;
- Use social gaming to encourage healthy lifestyle habits;
Calculate calories burned in a workout.
Software functions that enable individuals to interact with EHR software certified under the ONC Health IT Certification Program – These are software functions that provide individuals with access to health record systems or enable them to gain electronic access to health information stored within an EHR system. Software functions that only allow individuals to view, transfer, or download EHR data are also included in this category.

Brief description of certain device regulatory requirements
This Appendix provides a high level description of certain regulatory requirements for medical devices, including device software functions. The FDA has additional resources and publications online that describe these and other requirements in detail.
1. Establishment Registration and Medical Device Listing
Under 21 CFR Part 807, manufacturers of medical devices are required to annually register their establishments with FDA and provide a list of the devices they market. The registration and listing requirement is a means of keeping FDA advised of who is manufacturing devices, and of the types of devices an establishment is manufacturing. Medical device manufacturers are required to register their establishments with FDA and to list by identifying to FDA the devices they are marketing.
Additional information can be found in “Device Advice: Device Registration and Listing”. If you need further assistance, you may contact the Division of Risk Management Operations, Regulatory Policy and Systems Branch: Email: email@example.com, phone: 301-796-7400. Assistance is also available from, Division of Industry and Consumer Education (DICE): Email: DICE@fda.hhs.gov, phone: 301-796-7100 or 800-638-2041.
2. Investigational Device Exemption (IDE) requirements
An IDE allows an investigational device to be used in a clinical study in order to collect safety and effectiveness data required to support a Premarket Approval (PMA) application or a Premarket Notification 510(k) submission to FDA. Clinical studies with devices of significant risk must be approved by FDA and by an Institutional Review Board (IRB) before the study can begin. Studies with devices of non-significant risk must be approved by the IRB only before the study can begin.
Medical device manufacturers who are creating software with novel technologies are encouraged to engage in early collaboration meetings with the FDA to receive recommendations for testing and development of those devices requiring clinical investigations to support marketing.
Additional information about these meetings is described in guidance issued on February 28, 2001: “Early Collaboration Meetings Under the FDA Modernization Act (FDAMA); Final Guidance for Industry and for CDRH Staff”.
Further information regarding the investigational device exemption can be found in “Device Advice: Investigational Device Exemption”.
3. Labeling requirements
Medical device manufacturers are required to comply with applicable labeling regulations found in 21 CFR Part 801 for medical devices and 21 CFR Part 809 for in vitro diagnostic products.
4. Premarket submission for approval or clearance
Medical device manufacturers should identify the current classification covering their device. Manufacturers are required to prepare and submit to the FDA an appropriate premarket submission, as required for their device classification.
Additional information can be found in “Device Advice: Device Registration and Listing”.
5. Quality System Regulation (QS Regulation)
Medical device manufacturers are required to comply with the QS regulation. The QS regulation does not prescribe in detail how a manufacturer must produce a specific device, but provides a framework for all manufacturers to develop and follow to help ensure that their products consistently meet applicable requirements and specifications. As part of this framework, manufacturers are required to develop requirements for their products that will result in devices that are safe and effective, and to establish methods and procedures to design, produce, and distribute their devices.
Furthermore, manufacturers are required, as part of the QS regulation (21 CFR 820.30), to appropriately verify and validate their device software functions along with the computing platform to ensure safe and effective operation of the device.
Manufacturers are required to ensure that adequate controls and processes are in place through purchasing controls to ensure safe distribution, installation, and operation of the device software function.
Additional information regarding the QS regulation and can be found at “Quality System (QS) Regulation/Medical Device Good Manufacturing Practices”.
6. Medical Device Reporting (MDR) (Adverse event reporting)
The Medical Device Reporting (MDR) regulation requires manufacturers and importers of medical devices to submit reports to the FDA whenever they receive or otherwise become aware of information, from any source, that reasonably suggests that a device they market may have caused or contributed to a death or serious injury, or has malfunctioned and the device or a similar device that they market would be likely to cause or contribute to a reportable death or serious injury if the malfunction were to recur. MDR requires medical device manufacturers to:
- Submit MDR reportable events involving their medical devices as described in 21 CFR 803.10(c) and 803.50;
- Submit 5-day reports as described in 21 CFR 803.53;
- Submit supplemental reports as described in 21 CFR 803.56;
- Develop, maintain, and implement written procedures for the identification and evaluation of all medical device events to determine whether the event is MDR reportable as described in 21 CFR 803.17;
- Conduct an investigation of each event and evaluate the cause of the event as described in 21 CFR 803.50(b)(3); and
- Establish and maintain complete files for all complaints concerning adverse medical device events as described in 21 CFR 803.18.
The MDR report (FDA Form 3500A) must contain all the information described in 21 CFR 803.52 that is reasonably known to the manufacturer. Information reasonably known includes any information that:
- Can be obtained by contacting a user facility, importer, or other initial reporter;
- Is in the possession of the manufacturer; or
- Can be obtained by analysis, testing, or other evaluation of the device.
For additional instructions on how to complete the 3500A form, refer to the document titled “Instructions for Completing Form FDA 3500A”.
For additional guidance on the MDR regulation and the reporting requirements, refer to the document titled “Medical Device Reporting for Manufacturers”.

7. Correcting Problems
A medical device manufacturer may voluntarily take action at any time or may be requested to take action by the FDA to correct problems. Voluntary action is usually taken by device manufacturers. Examples of the types of actions that a device manufacturer may be requested to take include, but are not limited to:
- Inspecting the device for problems;
- Repairing the device;
- Adjusting settings on the device; and
- Upgrading software to reduce risk from a “bug” or unintended response.
Under certain circumstances, FDA may initiate a request that a manufacturer address a problem with a device through other means, including by removal of the product from the market. When recommending corrective action, the FDA intends to take into account the essential role that certain device software functions take as an integral part of a larger patient care system.
Reporting Corrections to FDA:
In accordance with 21 CFR 806.10, medical device manufacturers are required to promptly report, within 10 working days from the time the correction is initiated, to the FDA certain actions concerning device corrections and removals. Specifically, medical device manufacturers are required to report to FDA any corrections made to a device to reduce a risk to health posed by the device or to remedy a violation of the FD&C Act caused by the device that may present a risk to health.
The reporting requirement does not extend to all modifications to devices. For example, certain actions that would improve the quality of a mobile medical app but that would not reduce a risk to health posed by the mobile medical app or remedy a violation of the FD&C Act are not required to be reported under 21 CFR 806.1(b). If there is not a "risk to health" involved, a report to FDA is not required, but the device manufacturer must keep a record of the correction. An example of such action taken by the manufacturer could be changes made to correct a defect that creates a nuisance for the user but does not present a risk to the health of the user or patient.
More information about reporting requirements under 21 CFR Part 806 is available in “Device Advice: Recalls, Corrections, and Removals”.
Frequently Asked Questions (FAQs)
1) I have a software function that is not identified in this guidance. What is the best way to get additional information from the FDA about my product?
Answer: FDA recognizes that this guidance does not describe all types of software used in health care. Some manufacturers may be unsure whether their software function is considered a medical device that is subject to regulatory oversight, or whether their medical device could be under FDA’s intent to exercise enforcement discretion. If the device is subject to regulatory oversight, manufacturers may have questions about which regulatory requirements are applicable to their software function.
After reviewing this guidance, FDA encourages software manufacturers to contact the Agency to obtain more information using one of the following ways:
Phone or e-mail – For information about regulatory requirements, contact the Division of Industry and Consumer Education (DICE). Email: DICE@fda.hhs.gov; phone: 301-796-7100 or 800-638-2041.
For information about whether your software or mobile app is considered a medical device, contact firstname.lastname@example.org.
If your question relates to apps used in blood establishments or another area of CBER regulation, contact the Office of Communication, Outreach and Development, Center for Biologics Evaluation and Research, 10903 New Hampshire Ave., Bldg. 71, Room 3128, Silver Spring; e-mail: email@example.com; phone: 1-800-835-4709 or 240-402-7800.
Online – The FDA has several resources and publications online that describe various regulatory requirements in detail. FDA’s “Device Advice” website and online courses at “CDRH Learn” are a good place to start. Other sections in this guidance provide links to more detailed information related to more specific topics.
Letter – For written feedback about the classification and the regulatory requirements that may be applicable to a device software function, manufacturers should use the 513(g) process. Specifically, a manufacturer should submit the following for a 513(g) submission:
- User fee;
- Cover letter;
- Description of the software;
- Description of what the software is to be used for; and
- Any proposed labeling or promotional material for the software and, as applicable, any labeling or promotional material of a similar, legally marketed device, if available.
FDA will generally issue a response to the 513(g), in the form of a confidential letter to the manufacturer, within 60 days of receipt of the request for information. For more specific information about what to include in a 513(g) and where to send it, refer to FDA’s guidance document titled “FDA and Industry Procedures for Section 513(g) Requests for Information Contains Nonbinding Recommendations Under the Federal Food, Drug, and Cosmetic Act”. For more information about 513(g) user fees, refer to FDA’s guidance document titled “User Fees for 513(g) Requests for Information”.
2) Why does FDA recommend that manufacturers follow the Quality System (QS) regulation for those software that MAY be devices and could be device software functions but for which FDA intends to exercise enforcement discretion?
Answer: FDA believes all manufacturers of medical device software should have in place an adequate quality management system that helps ensure that their products consistently meet applicable requirements and specifications and can support the software throughout its total life cycle. Adequate quality management systems incorporate appropriate risk management strategies, good design practices, adequate verification and validation, and appropriate methods to correct and prevent risks to patients and adverse events that may arise from the use of the product. All of these elements are part of FDA’s QS regulation.
3) Is FDA’s QS regulation similar to software development practices I already use?
Answer: Most likely. Though not all of the principles in the QS regulation are applicable to the development and manufacture of quality device software functions, the majority of them are applicable and are consistent with commonly used and accepted good software development practices, such as those from the Institute of Electrical and Electronics Engineers’ (IEEE), Software Engineering Body of Knowledge (SWEBOK), and Carnegie Mellon Software Engineering Institute’s Capability Maturity Model Integration (CMMI) methods.
The FDA’s approach to QS regulation is also harmonized with certain international standards such as ISO 9001 and ISO 13485. Similar to these international standards, the QS regulation does not prescribe in detail how a manufacturer must produce a specific device, but provides a framework for all manufacturers to develop and follow to help ensure that their products consistently meet applicable requirements and specifications. The QS regulation can apply to and be scaled for any size manufacturer and any type of product. It also allows for a manufacturer to choose those requirements most appropriate for its given device and manufacturing process.
4) What are some examples of parts of the QS regulation that are of particular importance to device software functions and where can I find more information about them?
Answer: Though not a complete list, some examples of principles within the QS regulation that are relevant to all device manufacturers include risk assessment and management, design controls, and corrective and preventive actions. Risk assessment and management is a critical part of good quality management systems. Good design practices are important to the development and manufacture of safe medical devices. It is also important for manufacturers to have procedures in place to identify, analyze, correct, and prevent software-related causes of patient or user harm. References related to these examples are provided in Appendix E of this guidance. Additional references about these principles that manufacturers may find useful include the following:
FDA’s “General Principles of Software Validation” guidance.
5) Do all the device software function manufacturers have to submit a premarket submission and receive FDA clearance or approval before marketing?
Answer: No, not all manufacturers have to submit a premarket submission (i.e., a 510(k) or PMA) prior to marketing their device software function. This determination depends on the classification of the device. Manufacturers of devices that are exempt from 510(k) or PMA requirements do not have to file a submission with FDA prior to marketing their device. For example, the majority of class I devices are exempt from the premarket submission requirements and are subject to the least regulatory control.
Regardless of whether medical devices are subject to the premarket submission requirements, most medical devices (including Class I devices) have to comply with other basic regulatory requirements that are called “General Controls.” More information about what “General Controls” are and what a medical device manufacturer should do to comply with these requirements, can be found in “Device Advice: General Controls for Medical Devices” and “Regulatory Controls.”
6) Some FDA classifications state they are “510(k) exempt.” What does 510(k) exempt mean and how do I know if it applies to my product?
Answer: If a classification states the device type is “510(k) exempt,” this means that the manufacturer is not required to submit a premarket notification (i.e., a 510(k)) prior to marketing the device. However, the 510(k) exemption may be subject to certain limitations. Manufacturers are encouraged to confirm the device’s exempt status and any limitations to that status that may apply in accordance with 21 CFR Parts 862-892. Additional information about 510(k) exempt devices can be found at: https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpcd/315.cfm.
7) If a 510(k) is required for my device software function, what type of software documentation does FDA recommend I include in the submission?
Answer: FDA’s recommendations for the software-related documentation that you provide in your premarket submission are addressed in detail in the FDA’s “Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices”.
If the device software function uses off-the-shelf software, manufacturers should also refer to FDA’s “Guidance for Industry, FDA Reviewers, and Compliance on Off-the-Shelf Software Use in Medical Devices.”
8) I am a medical device manufacturer and making my product labeling available electronically using a mobile app. Is my app considered a mobile medical app?
Answer: Mobile apps that provide electronic access and are intended for use as a digital version of medical device labeling or instructions for use are not considered a medical device on their own and therefore are not considered mobile medical apps. These are apps from a device manufacturer that provide information to support the company’s own device. Examples include apps that provide an electronic copy of cleared or approved medical device labeling or apps that provide video instruction for how to use a medical device. These types of apps are not considered devices within themselves, but instead are considered part of the medical device labeling and are subject to the regulatory labeling requirements relevant to that particular product.
9) Is an electronic method of collecting clinical investigations, for example through a mobile app, considered a device software function, and if so, what requirements apply?
Answer: Software used for data collection in clinical studies (such as electronic Patient Reported Outcomes (ePRO) apps) is not considered on its own to be a device software function. However, manufacturers and users of this type of software should see FDA’s guidance related to use of computers in clinical trials, “Electronic Source Data in Clinical Investigations”, issued on September 17, 2013.
10) I am a medical device manufacturer. Is an electronic method of collecting and storing quality systems information in my manufacturing process considered a medical device?
Answer: Software used in the production process for medical devices, or for collecting, storing and maintaining quality system data collection for medical devices (including complaint submissions) is not considered a medical device on its own. This software does not meet the definition of medical device but is part of the quality system. However this software is required to comply with the appropriate good manufacturing practices (GMP) regulations (see 21 CFR Part 820).
