Code System Browsing: A Reference Guide for Healthcare Data Standardization
24756006 - Browse Code Systems
Summary
This page provides an interface to comprehensively search and manage multiple code systems, such as the Unified Medical Language System (UMLS). It clearly details its relevance to major interoperability standards like FHIR and HL7v2/v3, serving as a reference source for standardizing and exchanging medical data.
Details
This page offers detailed reference functionality for browsing UMLS code systems. Users can search for specific medical concepts or code sets from multiple views, including 'Search View,' 'Detail View,' and 'Tree View.' Key code systems mentioned include LOINC, HCPCS Level I/II, and CDC CVX. Crucially, in the context of FHIR (Fast Healthcare Interoperability Resources), the system explicitly states that the provided code systems derive directly from the HL7 FHIR source of truth. Specifically, it details the origins for FHIR.R4 external and internal code systems, as well as those derived from HL7v3 and HL7v2, establishing a foundation for standardized data exchange. Furthermore, the interface includes ValueSet management capabilities, providing separators (space, vertical bar, semicolon) and REST API URLs for combining codes. This is vital for defining datasets used in clinical settings and preparing them for system-to-system exchange. The function is critical for ensuring code standardization and interoperability in medical information, making it a valuable reference resource for addressing international data linkage challenges faced by Japanese electronic health record and claims systems.
