SNOMED CT
Systematized Nomenclature of Medicine Clinical Terms, a comprehensive clinical terminology used to code clinical findings, procedures, and diagnoses.
SNOMED CT contains over 350,000 concepts organized in a polyhierarchy with defining relationships. It is used for problem lists, diagnoses, procedures, and clinical findings in EHRs and FHIR resources. SNOMED CT is maintained by SNOMED International and licensed per country. It complements ICD (used for billing) and LOINC (used for observations). Mapping between SNOMED CT and ICD-10 is a common requirement.
