SNOMED CT is a clinical terminology used in electronic health records; AutoICD's coding API returns SNOMED CT IDs alongside each ICD-10 code via the include_snomed=true flag.
What UMLS Concept Unique Identifiers (CUIs) cover schizophrenia?
The ICD-10 codes for schizophrenia are linked to at least 25 UMLS CUIs in the National Library of Medicine's Metathesaurus. Sample CUIs include C0036341, C0036349, C0036347, C0036344, C0392322.
