ICD-11 Classification for Fine Motor Delay

Clinicians searching ICD-11 for a discrete "Fine Motor Delay" code soon discover it is a functional descriptor, not a standalone diagnostic category — and that distinction matters for accurate coding.

In short

There is no dedicated ICD-11 code titled "Fine Motor Delay." It is a clinical descriptor of below-expected manual dexterity and precision (grasp, pincer grip, manipulation, graphomotor skill) for chronological age. Where it represents a persistent disorder of motor coordination, it is captured under ICD-11 6A04 Developmental motor coordination disorder; where it is one feature within broader delay it falls under LD16.4 Global developmental delay or the relevant primary condition. Functional impact is described separately via the ICF.

Where it sits in ICD-11

Fine motor delay is best understood as a finding requiring you to identify the underlying entity:

• 6A04 Developmental motor coordination disorder — when impaired fine motor acquisition and execution are significantly below age expectation, are not explained by a neurological or visual condition, and interfere with daily activities or academic performance.
• LD16.4 Global developmental delay — when fine motor difficulty co-occurs with delay across multiple domains in a child under 5, where formal assessment is not yet feasible.
• Secondary descriptor — fine motor delay arising from cerebral palsy (8D2_), genetic syndromes, or sensory/visual impairment is coded to the primary condition, with motor function then profiled functionally.

For the functional layer, the WHO ICF provides codes for hand and arm use and fine hand use (mobility/activity domains), enabling you to document severity and participation impact independently of aetiology — the framework that underpins goal-setting in therapy.

When to refer

Refer for structured developmental assessment when manual milestones lag persistently (e.g. absent pincer grasp beyond ~12 months, inability to manage age-typical self-feeding, fastenings, or graphomotor tasks), when delay is asymmetric or regressive, or when fine motor concerns sit alongside language, gross motor or social differences. Asymmetry, hypertonia, or skill loss warrant prompt neurological 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 an online form or code lookup. Our occupational therapy teams profile fine motor function within the ICF activity-and-participation framework, so coding translates into a measurable plan. Explore how we work across our network.
