Overview of Code System Management using UMLS and FHIR
Browse Code Systems - VSAC - NIH
Summary
This page introduces the search and management functionality for code systems, combining large medical knowledge bases like UMLS (Unified Medical Language System) with standards such as FHIR (Fast Healthcare Interoperability Resources). Users can systematically reference various types of codes and terms to acquire necessary information for building Value Sets.

This page provides a structured reference interface for complex code system structures within healthcare IT. It suggests the integration of multiple standard specifications, including UMLS Concepts (CUI) and FHIR resource definitions. Functionally, it allows access to data from multiple perspectives—such as 'Search View,' 'Detail View,' and 'Tree View'—and confirms detailed information like Code, Descriptor, and version management (Code System Version). Furthermore, it enables referencing information from external and internal code systems across various FHIR editions (R4, HL7v3, v2). It also mentions specific medical coding systems like LOINC and HCPCS, explaining the technical background of how these are standardized and utilized as Value Sets. This serves as a reference for Japanese healthcare institutions facing the challenge of integrating multiple disparate legacy code systems.
