# What is the ICD-11 classification for Gross Motor Delay?

ICD-11 has no standalone 'Gross Motor Delay' code; it is a functional descriptor. When persisting and predominant it maps to Developmental motor coordination disorder (6A04); within global delay to Disorders of intellectual development (6A00); transient isolated delay to milestone symptom codes — with any underlying aetiology coded separately.

*In ICD-11, gross motor delay is not a diagnosis in its own right — it is a functional descriptor that points toward an underlying developmental picture.*

## In short
ICD-11 does not carry a standalone code labelled "Gross Motor Delay". It is a **clinical descriptor** of below-expected attainment of postural and locomotor milestones (head control, sitting, crawling, standing, walking) for chronological age. Where it is the predominant and persisting feature, the most fitting ICD-11 entry is **Developmental motor coordination disorder (6A04)** within Neurodevelopmental disorders; where motor delay co-occurs with global cognitive, language and adaptive delay, it falls under **Disorders of intellectual development (6A00)**. Isolated, often transient delay in an otherwise healthy infant is captured by symptom-and-sign codes for delayed milestones rather than a disorder code.

## Where it sits in ICD-11
- **6A04 Developmental motor coordination disorder** — significant motor-skill acquisition and execution below age expectation, not explained by intellectual disability, visual impairment or a neurological condition; appropriate when gross motor difficulty is the core, persisting picture.
- **6A00 Disorders of intellectual development** — when gross motor delay is one strand of a broader, global developmental delay.
- **Symptoms/signs chapter (MB-series)** — "delay in achievement of expected physiological developmental milestone" for young infants where the delay may be transient, isolated and not yet meeting disorder thresholds.
- Always code the **underlying aetiology separately** when known — e.g. cerebral palsy (8D2_), neuromuscular disorders, or genetic syndromes — since motor delay is frequently a downstream manifestation, not the primary entity.

Clinically, the descriptor's value is directional: it signals the need to clarify whether the delay is isolated, syndromic, or neurological, and whether it is static or progressive. Progressive loss of motor skill, marked asymmetry, hypertonia or regression warrants prompt neurological referral rather than a watch-and-monitor stance.

## The Pinnacle way
Developmental measurement supports care planning; diagnosis requires an appropriately qualified healthcare professional., under qualified clinician care — never from an online descriptor or self-assessment. Our structured, [clinician-administered AbilityScore®](/ask/what-is-the-abilityscore-and-how-is-it-calculated) profiles motor functioning alongside the other developmental domains, and [paediatric physiotherapy and occupational therapy](/) pathways turn that profile into a measurable plan toward independence.

## Trusted sources
WHO ICD-11 for Mortality and Morbidity Statistics (Neurodevelopmental disorders chapter); WHO International Classification of Functioning, Disability and Health (ICF) framework for functioning descriptors; AAP developmental surveillance guidance on motor milestone monitoring.

**Next step —** For a child with persisting or asymmetric motor delay, [arrange a Pinnacle developmental assessment](/) to clarify the underlying picture and define a therapy plan.
