ICDSNOMED

ICDSNOMED is a term used in health informatics to describe efforts to align the International Classification of Diseases (ICD) with SNOMED Clinical Terms (SNOMED CT). While not a formal standard with a single governing body, the phrase is employed in literature and project documentation to denote crosswalks, mappings, and shared semantics intended to improve semantic interoperability between diagnostically coded data and granular clinical terminology.

In practice, ICDSNOMED initiatives aim to provide bidirectional mappings between ICD codes (such as ICD-10-CM/ICD-11) and SNOMED CT concepts, along with common ontologies, coding rules, and release management processes. The goal is to enable accurate data exchange, unified clinical documentation, and reliable analytics, reporting, and decision support across EHRs and health information systems.

There is no globally mandated body called ICDSNOMED. Instead, organizations rely on established resources and crosswalks produced by WHO for ICD, SNOMED International for SNOMED CT, and national authorities for local implementations. Ongoing projects focus on improving bidirectional mappings, maintaining alignment across terminology releases, and integrating these mappings into workflows, databases, and reporting pipelines.

Potential benefits include improved data quality, interoperability across care settings and systems, better epidemiological reporting, and more accurate billing and reimbursement processes. Challenges include semantic differences between frameworks, the complexity of one-to-many mappings, ongoing maintenance with versioning, licensing considerations for SNOMED CT, and ensuring alignment as ICD and SNOMED CT evolve.
