SNOMED CT Concept for Gross Motor Delay

When a child presents with delayed sitting, crawling or walking, the coding question follows fast: how do we record gross motor delay in SNOMED CT?

In short

Gross Motor Delay is represented in SNOMED CT under the broader concept of delayed motor development. The most directly applicable clinical finding is Delayed gross motor development (SNOMED CT concept ID 22951005, Delayed motor development, with finer-grained children where the terminology edition supports them). Always validate the exact concept ID against your live SNOMED CT browser and national edition, as identifiers and hierarchy placement can vary by release and extension.

Coding the concept

In the SNOMED CT International Edition, gross motor delay sits within the Clinical finding hierarchy as a developmental finding:

• Parent concept: Delayed motor development — the general descriptor for motor milestones acquired later than expected for chronological age.
• For specificity, pair the finding with an age or milestone qualifier and the relevant motor domain (gross versus fine) where your edition's reference set allows.
• For cross-mapping to billing or surveillance systems, SNOMED CT maps to ICD-11 functioning-related categories; the WHO ICF (b/d codes for mobility) better captures the functional picture than a single diagnostic code.

A SNOMED CT finding records what was observed, not severity or cause. Document the underlying aetiology (e.g. hypotonia, prematurity, neuromuscular condition) and functional impact separately, so the record supports both coding fidelity and intervention planning.

When to refer

Isolated gross motor delay with normal tone, reflexes and progression often warrants monitoring and parent guidance. Refer promptly where there is loss of acquired skills, asymmetry, persistent hypotonia or hypertonia, or delay across multiple domains — these warrant paediatric neurology or developmental review rather than therapy-first management.

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. Coding captures the finding; a structured, clinician-administered assessment captures the child. Pinnacle's physiotherapy and motor-development pathway translates a recorded delay into a measurable plan, and you can partner with our clinical team for collaborative care.

Trusted sources

WHO ICD-11 for cross-mapping of developmental findings; WHO International Classification of Functioning, Disability and Health (ICF) for the mobility functioning picture. Always confirm the live concept ID in your national SNOMED CT edition.

Next step — Validate the concept in your SNOMED CT browser, then partner with a Pinnacle clinician to convert the finding into a measurable motor-development plan.
