Health informatics - Device interoperability - Part 10425: Personal Health Device Communication - Device Specialization- Continuous Glucose Monitor (CGM) (ISO/IEEE 11073-10425:2024)

This standard establishes a normative definition of communication between personal health continuous glucose monitor (CGM) devices (agents) and managers (e.g., cell phones, personal computers, personal health appliances, set top boxes) in a manner that enables plug-and-play interoperability. It leverages work done in other ISO/IEEE 11073 standards including existing terminology, information profiles, application profile standards, and transport standards. It specifies the use of specific term codes, formats, and behaviors in telehealth environments, restricting optionality in base frameworks in favor of interoperability. This standard defines a common core of communication functionality of CGM devices. In this context, CGM refers to the measurement of the level of glucose in the body on a regular (typically 5 minute) basis through a sensor continuously attached to the person.

La présente norme établit une définition normative de la communication entre des dispositifs (agents) et des gestionnaires de glucomètres continus (CGM) personnels de santé (par exemple des téléphones cellulaires, des ordinateurs personnels, des équipements personnels de santé, des boîtiers décodeurs) d’une manière qui permet une interopérabilité du type prêt à l’emploi. Elle s’appuie sur le travail réalisé dans d’autres normes ISO/IEEE 11073, y compris la terminologie, des modèles d’informations, des normes de profils d’applications et des normes de transport. Elle spécifie l’utilisation de codes, de formats et de comportements en termes spécifiques dans les environnements de télésanté, en limitant les choix à des cadres de travail de base en faveur de l’interopérabilité. La présente norme définit un noyau commun de fonctionnalités de communication des dispositifs CGM. Dans ce contexte, CGM désigne la mesure du niveau de glucose dans l’organisme relevé régulièrement (généralement toutes les 5 minutes) par le biais d’un capteur relié en permanence à la personne.

Overview

EN ISO/IEEE 11073-10425:2025 (ISO/IEEE 11073-10425:2024) defines a normative, plug-and-play communication framework for Continuous Glucose Monitors (CGM) and their managers (e.g., smartphones, PCs, personal health appliances, set‑top boxes). As part of the ISO/IEEE 11073 family, this device specialization standard prescribes a common core of communication functionality, leveraging existing 11073 terminology, information models and transport/application profiles to enable interoperable telehealth and personal‑health device ecosystems.

Key technical topics and requirements

• Device‑manager communication model: Normative definition of how CGM agents and managers exchange data to support continuous glucose measurement workflows.
• Terminology and information profiles: Uses ISO/IEEE 11073 terminology and information models to ensure consistent semantics across vendors.
• Restricted optionality for interoperability: Specifies required term codes, formats and behaviors and reduces optional choices in base frameworks to improve plug‑and‑play compatibility.
• Data formats and behaviors: Defines standardized term codes, attribute handling and message behaviors for CGM use cases (e.g., periodic sensor glucose reporting).
• Protocol/version and nomenclature management: Aligns nomenclature-version with protocol-version and clarifies precedence among 10101, 20601, 104xx and this device specialization.
• Normative references: References other standards such as IEEE Std 11073-20601 (device communication framework) and ISO/IEEE 11073-10101 (nomenclature) as part of the normative baseline.
• Telehealth focus: Emphasizes behaviors suitable for remote monitoring and personal health device scenarios, including common reporting cadence (typically ~5 minutes for CGM).

Practical applications and users

Who benefits:

• Medical device manufacturers building CGM sensors or transmitters seeking standardized, interoperable connectivity.
• Mobile and software developers integrating CGM data into apps, cloud services or electronic health records (EHRs).
• Healthcare providers and telehealth platforms needing reliable, standardized CGM feeds for remote monitoring and decision support.
• Test labs and regulators evaluating device conformance, safety and interoperability. Practical uses include plug‑and‑play pairing of CGM devices with smartphones, secure streaming of glucose data to health apps and EHRs, and consistent data exchange for clinical monitoring or research.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee has
been established has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types of
ISO document should be noted (see www.iso.org/directives).
IEEE Standards documents are developed within the IEEE Societies and the Standards Coordinating
Committees of the IEEE Standards Association (IEEE-SA) Standards Board. The IEEE develops its standards
through a consensus development process, approved by the American National Standards Institute, which
brings together volunteers representing varied viewpoints and interests to achieve the final product.
Volunteers are not necessarily members of the Institute and serve without compensation. While the IEEE
administers the process and establishes rules to promote fairness in the consensus development process, the
IEEE does not independently evaluate, test, or verify the accuracy of any of the information contained in its
standards.
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent rights
in respect thereof. As of the date of publication of this document, ISO had not received notice of (a) patent(s)
which may be required to implement this document. However, implementers are cautioned that this may not
represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.

Abstract: Within the context of the ISO/IEEE 11073 family of standards for device communication, a
normative definition of the communication between continuous glucose monitor (CGM) devices and
managers (e.g., cell phones, personal computers, personal health appliances, set top boxes), in a manner that
enables plug-and-play interoperability, is established in this standard. It leverages appropriate portions of
existing standards including ISO/IEEE 11073 terminology and information models. It specifies the use of
specific term codes, formats, and behaviors in telehealth environments, restricting optionality in base
frameworks in favor of interoperability. This standard defines a common core of communication functionality
of CGM devices. In this context, CGM refers to the measurement of the level of glucose in the body on a regular
(typically 5 minute) basis through a sensor continuously attached to the person.

Comments on standards
Comments for revision of IEEE Standards documents are welcome from any interested party, regardless of membership
affiliation with IEEE or IEEE SA. However, IEEE does not provide interpretations, consulting information, or advice
pertaining to IEEE Standards documents.
Suggestions for changes in documents should be in the form of a proposed change of text, together with appropriate supporting
comments. Since IEEE standards represent a consensus of concerned interests, it is important that any responses to comments
and questions also receive the concurrence of a balance of interests. For this reason, IEEE and the members of its Societies and
Standards Coordinating Committees are not able to provide an instant response to comments, or questions except in those cases
where the matter has previously been addressed. For the same reason, IEEE does not respond to interpretation requests. Any
person who would like to participate in evaluating comments or in revisions to an IEEE standard is welcome to join the relevant
IEEE working group. You can indicate interest in a working group using the Interests tab in the Manage Profile & Interests area
of the IEEE SA myProject system. An IEEE Account is needed to access the application.
Comments on standards should be submitted using the Contact Us form.
Laws and regulations
Users of IEEE Standards documents should consult all applicable laws and regulations. Compliance with the provisions of any
IEEE Standards document does not constitute compliance to any applicable regulatory requirements. Implementers of the
standard are responsible for observing or referring to the applicable regulatory requirements. IEEE does not, by the publication
of its standards, intend to urge action that is not in compliance with applicable laws, and these documents may not be construed
as doing so.
Data privacy
Users of IEEE Standards documents should evaluate the standards for considerations of data privacy and data ownership in the
context of assessing and using the standards in compliance with applicable laws and regulations.
Copyrights
IEEE draft and approved standards are copyrighted by IEEE under US and international copyright laws. They are made

Introduction
This introduction is not part of IEEE Std 11073-10425-2023, Health Informatics—Device Interoperability—Part 10425: Personal Health
Device Communication—Device Specialization—Continuous Glucose Monitor (CGM).
ISO/IEEE 11073 standards enable communication between medical devices and external computer systems. This document uses
the optimized framework created in ISO/IEEE 11073-20601 and describes a specific, interoperable communication approach for
continuous glucose monitors (CGMs). These standards align with, and draw on, the existing clinically focused standards to
provide support for communication of data from clinical or personal health devices (PHDs).

Health Informatics—Device Interoperability
Part 10425:
Personal Health Device Communication—Device
Specialization—Continuous Glucose Monitor (CGM)
1. Overview
1.1 Scope
This standard establishes a normative definition of communication between personal health continuous glucose monitor (CGM)
devices (agents) and managers (e.g., cell phones, personal computers, personal health appliances, set top boxes) in a manner that
enables plug-and-play interoperability. It leverages work done in other ISO/IEEE 11073 standards including existing
terminology, information profiles, application profile standards, and transport standards. It specifies the use of specific term
codes, formats, and behaviors in telehealth environments, restricting optionality in base frameworks in favor of interoperability.
This standard defines a common core of communication functionality of CGM devices. In this context, CGM refers to the
measurement of the level of glucose in the body on a regular (typically 5 minute) basis through a sensor continuously attached to
the person.
1.2 Purpose
This standard addresses a need for an openly defined, independent standard for controlling information exchange to and from
personal health devices (PHDs) and compute engines (e.g., cell phones, personal computers, personal health appliances, set top
boxes). Interoperability is the key to growing the potential market for these devices and to enabling people to be better informed
participants in the management of their health.
1.3 Word usage
The word shall indicates mandatory requirements strictly to be followed in order to conform to the standard and from which no
2, 3
deviation is permitted (shall equals is required to).
The word should indicates that among several possibilities one is recommended as particularly suitable, without mentioning or
excluding others; or that a certain course of action is preferred but not necessarily required (should equals is recommended that).
The word may is used to indicate a course of action permissible within the limits of the standard (may equals is permitted to
