This is the clinical terminology identifier — distinct from classification codes ICD-11 6C90 and ICD-10-CM F91.3, to which national terminology services maintain map sets. Diagnosis itself is made only by a clinician.","answer_md":"*When ODD enters a child's record, the code you attach determines whether that record speaks to every other system.*\n\n## In short\nIn **SNOMED CT**, Oppositional Defiant Disorder is represented by the concept **31755006 | Oppositional defiant disorder (disorder)**, a child of the disturbance-of-conduct hierarchy within Clinical finding. This is distinct from its classification codes — **ICD-11 6C90** and ICD-10-CM **F91.3** — which serve statistical and reporting purposes. SNOMED CT is the terminology layer for the clinical record; ICD is the classification layer for reporting and morbidity coding.\n\n## Terminology versus classification\nSNOMED CT is a *reference terminology* designed for the point of care — capturing what the clinician records, supporting decision support, retrieval and interoperability across an EHR. The concept identifier **31755006** is a stable, machine-readable anchor; its fully specified name carries the *(disorder)* semantic tag, and it sits beneath the conduct- and emotional-disturbance subhierarchies.\n\nICD-11, by contrast, is a *classification* for aggregate reporting and epidemiology, where **6C90 Oppositional defiant disorder** lives under disruptive behaviour and dissocial disorders. National terminology services maintain map sets between SNOMED CT concepts and ICD codes, so a single recorded finding can be reported correctly without re-coding. Where India's ABDM/EHR standards reference SNOMED CT as a recognised terminology, using the concept ID rather than free text preserves that downstream mapping.\n\n## Practical note for the record\nCode the SNOMED CT concept at the point of clinical documentation; let your terminology service derive the ICD-11 6C90 (or ICD-10-CM F91.3) equivalent for reporting. Always confirm the current concept status and any inactivation or replacement in your live SNOMED CT International edition or the India national release, as concept lifecycle states can change between editions.\n\n## The Pinnacle way\nCoding supports the record; it does not make the diagnosis. A clinical [AbilityScore®](/ask/what-is-the-abilityscore-and-how-is-it-calculated) and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care — never from a code, a form or an app. For children where oppositional and regulation difficulties are part of the picture, our [behavioural and developmental therapy](/behavioural-therapy) teams work alongside the family. Start at our [home](/).\n\n## Trusted sources\nWHO ICD-11 for Mortality and Morbidity Statistics (foundation entry 6C90); SNOMED International reference terminology browser for concept lookup and semantic hierarchy.\n\n**Next step —** Verify the live concept status in your edition's SNOMED CT browser, then map to ICD-11 6C90 for reporting — and refer behavioural concerns to a Pinnacle clinician.\n\nThis is general information, not a diagnosis — individual assessment and diagnosis require an appropriately qualified healthcare professional.","canonical":"https://pinnacleblooms.org/ask/what-is-the-snomed-ct-concept-for-oppositional-defiant-disorder","editorial":{"reviewed_at":"2026-06-11T20:12:18.613642+00:00","reviewed_by":null,"developed_by":"SETU
