Conduct-Dissocial Disorder
SNOMED CT Concept for Conduct-Dissocial Disorder
ICD-11 codes this condition as Conduct-dissocial disorder (6C91). SNOMED CT has no verbatim concept of that name; the nearest active concept is Conduct disorder (disorder), with socialised and unsocialised descendants. Confirm the current concept ID and ICD-11 map in your live terminology server, as identifiers are versioned.
When two coding systems describe the same child, mapping matters — here's how Conduct-Dissocial Disorder sits across ICD-11 and SNOMED CT.
In short
Conduct-Dissocial Disorder is the ICD-11 term (code 6C91) for a persistent, repetitive pattern of behaviour that violates age-appropriate social norms, rules or the basic rights of others. SNOMED CT does not carry a single concept labelled "Conduct-Dissocial Disorder" verbatim; the nearest active SNOMED CT International concept is Conduct disorder (disorder), with related concepts such as Socialised conduct disorder and Unsocialised conduct disorder. Always confirm the current concept ID and any ICD-11–to–SNOMED CT map within your live terminology server, as identifiers and mappings are versioned and can change.The science, briefly
ICD-11 reorganised the former ICD-10 conduct-disorder family into Conduct-dissocial disorder (6C91), distinguishing childhood-onset from adolescent-onset and qualifying the presence of limited prosocial emotions. SNOMED CT, by contrast, is a clinical reference terminology built for the electronic record — it represents Conduct disorder as a fully defined concept with descendants for socialised and unsocialised presentations. Because the two systems were designed for different purposes (classification versus point-of-care recording), there is no guaranteed one-to-one equivalence: a single ICD-11 entity may map to several SNOMED CT concepts, or via an approximate ("target broader/narrower") map. For interoperability work, retrieve the concept directly from the SNOMED CT International or India edition browser rather than hard-coding an identifier.When this matters clinically
- EHR coding — record the behavioural pattern with the SNOMED CT Conduct disorder concept, and reserve 6C91 for ICD-11 statistical or claims reporting.
- Differential framing — distinguish from oppositional defiant disorder (6C90) and from disorders better explained by an emerging neurodevelopmental or trauma profile.
- Referral — co-occurring developmental, communication or regulation difficulties in a child warrant a structured developmental assessment, not a behavioural label alone.
The Pinnacle way
A clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care — never from a code lookup or an online form. Where conduct concerns coexist with developmental, communication or emotional-regulation needs, our behavioural and developmental therapy pathways and [child development assessment](/) bring structure to what a parent or referrer first noticed.Trusted sources

Frequently asked
Does SNOMED CT have a concept named exactly 'Conduct-Dissocial Disorder'?
No. 'Conduct-dissocial disorder' is the ICD-11 term (6C91). SNOMED CT International represents the nearest equivalent as 'Conduct disorder (disorder)', with related descendants such as socialised and unsocialised conduct disorder. Retrieve the active concept and identifier from your edition's terminology server.
What is the ICD-11 code for Conduct-Dissocial Disorder?
It is 6C91 in the ICD-11 Mental, behavioural or neurodevelopmental disorders chapter, describing a persistent pattern of behaviour violating age-appropriate norms or the rights of others, with childhood-onset and adolescent-onset qualifiers.
Is there a one-to-one map between ICD-11 6C91 and SNOMED CT?
Not necessarily. ICD-11 and SNOMED CT serve different purposes — classification versus clinical recording — so a single ICD-11 entity may map to one or several SNOMED CT concepts, sometimes via approximate broader or narrower maps. Always confirm against the current mapping resource.
