ICDhoidot

ICDhoidot is a fictional or speculative diagnostic coding framework that imagines an extension of the International Classification of Diseases (ICD) system to encompass a broader range of health phenomena. It is not an official standard and has no endorsement by the World Health Organization or national health authorities. The concept is used mainly in theoretical discussions, design research, and educational simulations to explore how standardized coding might capture digital health data, psychosocial factors, and patient-reported outcomes.

The name ICDhoidot blends the ICD acronym with a coined suffix intended to signal treatment, insight, or expanded diagnostic scope. The term is purposefully nontechnical in its etymology to emphasize its status as a design concept rather than a formal medical taxonomy.

Structure and coding in ICDhoidot are imagined to be hierarchical, with domains, subcategories, and granular items. A typical code might appear as ICDhoidot-HD01-001, followed by a concise definition, diagnostic criteria, and recommended clinical actions. The system is designed to be interoperable with real-world classifications such as ICD-10/11 and SNOMED CT through crosswalk mappings, enabling discussion of interoperability and data governance in a controlled, fictional context.

Applications of ICDhoidot include speculative design exercises, medical education simulations, and data-modeling projects that explore how digital phenotypes, sleep, mood, and social determinants might be organized in a unified scheme. Example domains might include HD for sleep disorders, CO for cognitive or affective phenomena, and SD for social determinants.

Reception of the concept is primarily within academic and design communities, where it is used to illustrate coding decisions and governance challenges. Critics caution that fictional systems must be clearly labeled to avoid confusion with real standards.
