The document defines the progression of implementation of terminology capability in information systems. This document does not specify requirements for any specific terminological resource. It is intended to provide a basis for conformance criteria for terminological resources capabilities in specific use cases. This document does not cover in detail the software being used, though the capabilities of that software are included and impact the level of maturity reached. This document is applicable to terminological resources of all types, terminologies, classifications, value sets, code systems, and value domains.

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 documents should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
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

Introduction
This document identifies a model for evaluation of the maturity of terminology implementation in healthcare
systems and identifies a maturity module for terminology implementation for use in electronic health
records (EHRs) and healthcare systems in general.
This document supports common activities of healthcare including:
— identification of the relationship between each terminology resource capability to the safety and
effectiveness of system use in healthcare;
— support healthcare software vendors and organizations to;
— compare software terminological resource capabilities and organizational requirements for those
resources;
— plan improvements, i.e. align requirements and capabilities, as needed;
— improve the safety and utility of healthcare information systems and the data in them, and the use of
terminological resources in applications such as clinical decision support systems;
— improve information sharing (semantic interoperability) between organizations and systems;
— support short and long-term analytics within the organization and more broadly to enable knowledge
acquisition.
The impact of tooling (including computer-assisted coding, speech recognition, template development) on
the capability of the terminological resources is not covered in detail in this document.
This document provides a model against which conformity can be measured and improvements made to
products and implementations with a positive impact both on efficiency and patient safety. This assists
implementation, reduces inappropriate spending, manages expectations more effectively and encourages
software vendors and decision makers at all levels to progress their products into higher functional capacity.
This document is also produced to encourage the development of the skills required to safely and efficiently
implement and use terminologies in healthcare systems.
The users of this document include:
— health care organisation, to assess product capabilities and plan future directions and purchases;
— vendors (including cloud services and conventional software products), to:
— support implementation of terminological resources in their products;
— enable semantic interoperability across different systems;
— assess product conformance requirements influencing future directions for software development;
— government and other decision makers;
— educators and educational organizations;
— terminological resource developers.
