ADHD
The SNOMED CT concept for ADHD
In SNOMED CT, ADHD is the concept 'Attention deficit hyperactivity disorder (disorder)', SCTID 406506008, the terminology counterpart to WHO ICD-11 6A05 and ICD-10 F90, with subtype descendants for inattentive, hyperactive-impulsive and combined presentations. Always verify against the active national edition.
A clean terminology crosswalk matters as much as the diagnosis itself — coding ADHD correctly is what makes records, referrals and research interoperable.
In short
In SNOMED CT, Attention deficit hyperactivity disorder is represented by the concept "Attention deficit hyperactivity disorder (disorder)", SCTID 406506008, a child of the disorder hierarchy. This is the clinical-terminology counterpart to WHO ICD-11 6A05 ("Attention deficit hyperactivity disorder") and the legacy ICD-10 F90 family. SNOMED CT additionally carries subtype descendants — predominantly inattentive, predominantly hyperactive-impulsive, and combined presentations — for finer-grained documentation. Always verify the active concept and any subtype mapping against your current national SNOMED CT edition, as descriptions and inactivations are revised at each release.How the coding fits together
SNOMED CT and ICD-11 serve complementary roles: SNOMED CT is the clinical reference terminology for capturing structured findings at the point of care, while ICD-11 (6A05) is the statistical and reporting classification. The WHO maintains an ICD-11–SNOMED CT mapping, and most EHRs use SNOMED CT for entry with downstream ICD mapping for claims and surveillance. For ADHD, note that the SNOMED hierarchy distinguishes presentation subtypes as separate descendant concepts rather than as post-coordinated qualifiers in most editions — so when documenting a combined presentation, select the specific child concept rather than the parent where your edition supports it.Clinically, the code is downstream of the assessment, not a substitute for it: ICD-11 6A05 and NICE NG87 both require that the symptom pattern is pervasive across settings, developmentally inappropriate, and functionally impairing before the concept is applied.
The Pinnacle way
Coding follows clinical formulation — never the reverse. At Pinnacle Blooms Network, a clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care, never from a form or an app. From there, structured terminology supports clean referrals and a coordinated plan across our network of [70+ centres](/) and our behavioural and developmental therapy pathways.Trusted sources
WHO ICD-11 6A05 (Attention deficit hyperactivity disorder); NICE NG87 on ADHD diagnosis and management; American Academy of Pediatrics guidance via HealthyChildren.org; Indian Academy of Pediatrics. SNOMED CT identifiers should be confirmed against your active national edition.Next step — Refer a child with suspected ADHD for structured clinician-led assessment — partner with a Pinnacle centre.

What to watch
Confirm the active SNOMED CT concept and any subtype descendant against your current national edition, as identifiers and descriptions are revised each release; ensure ICD-11 6A05 mapping is applied for reporting.
Try this at home
Enter ADHD via SNOMED CT at the point of care and let your EHR map to ICD-11 6A05 downstream — capture the specific presentation subtype concept rather than the parent where your edition supports it.

Frequently asked
What is the SNOMED CT concept ID for ADHD?
ADHD is represented by 'Attention deficit hyperactivity disorder (disorder)', SCTID 406506008. Always confirm the active concept against your current national SNOMED CT edition, as identifiers and descriptions are periodically revised.
How does the SNOMED CT concept relate to ICD-11 6A05?
SNOMED CT is the clinical reference terminology used at the point of care, while ICD-11 6A05 is the statistical and reporting classification. The WHO maintains an ICD-11–SNOMED CT mapping, so EHRs typically capture SNOMED CT and map to 6A05 for claims and surveillance.
Does SNOMED CT distinguish ADHD subtypes?
Yes — the hierarchy carries descendant concepts for predominantly inattentive, predominantly hyperactive-impulsive, and combined presentations. Where your edition supports them, select the specific child concept rather than the parent for finer documentation.
