The SNOMED CT concept for ADHD

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.
