ISO 9999
Pronunciation: eye-ess-oh nine-nine-nine-nine
The international standard classification system for assistive products, including orthotics, providing a hierarchical coding framework used in procurement and clinical documentation.
Full Definition
ISO 9999 (Assistive Products for Persons with Disability — Classification and Terminology) is published by the International Organization for Standardization and provides a three-level hierarchical code structure for all assistive technology, including orthotic devices. In orthotic services documentation, ISO 9999 codes are used in procurement specifications, national health service product databases, and cross-border data reporting. Editors reviewing procurement tenders or assistive technology policy documents should verify that ISO 9999 is written with a space between 'ISO' and '9999,' and that the full title is cited on first reference in formal documents. The standard undergoes periodic revision; editors must confirm the edition year when citing it in regulatory submissions.
Usage
Usage note: Include the edition year when citing in regulatory or procurement documents. Write as 'ISO 9999' with a space, not 'ISO9999.'
