The ICD-10 codes for bipolar disorder map to at least 25 SNOMED CT concepts. Examples of SNOMED CT concept IDs in this group include 1343347009, 31446002, 55516002, 68569003, 767632000. 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 bipolar disorder?
The ICD-10 codes for bipolar disorder are linked to at least 25 UMLS CUIs in the National Library of Medicine's Metathesaurus. Sample CUIs include C0005586, C0853193, C1852197, C5676454, C2874872.
