Oppositional Defiant Disorder
SNOMED CT Concept for Oppositional Defiant Disorder
In SNOMED CT, Oppositional Defiant Disorder is concept 31755006 | Oppositional defiant disorder (disorder). 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.
When ODD enters a child's record, the code you attach determines whether that record speaks to every other system.
In short
In 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.Terminology versus classification
SNOMED 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.ICD-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.
Practical note for the record
Code 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.The Pinnacle way
Coding supports the record; it does not make the diagnosis. A clinical AbilityScore® 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 teams work alongside the family.

What to watch
Confirm concept lifecycle status — SNOMED CT concepts can be inactivated or replaced between the International and India national editions, so verify in your live release before mapping.

Frequently asked
What is the SNOMED CT concept ID for Oppositional Defiant Disorder?
It is 31755006 | Oppositional defiant disorder (disorder) — a Clinical finding concept beneath the disturbance-of-conduct hierarchy. Always confirm current status in your live SNOMED CT edition, as concept states can change between releases.
How does the SNOMED CT concept relate to ICD-11 6C90?
SNOMED CT is a reference terminology for the clinical record; ICD-11 6C90 is a classification for reporting and morbidity statistics. National terminology services maintain map sets so a SNOMED-recorded finding can be reported as ICD-11 6C90 (or ICD-10-CM F91.3) without re-coding.
Why use SNOMED CT rather than just an ICD code in the record?
SNOMED CT is designed for point-of-care documentation, decision support and interoperability, with stable machine-readable concept identifiers. Recording the concept ID rather than free text preserves accurate downstream mapping to ICD for reporting.
Does the SNOMED CT code constitute a diagnosis?
No. The code supports the record; it does not establish a diagnosis. Diagnosis is a clinical judgement made by a qualified clinician — at Pinnacle Blooms Network, formed only at a centre under clinician care, alongside a structured AbilityScore® assessment.
