Persistent Toe-Walking
ICD-11 Classification of Persistent Toe-Walking
ICD-11 has no dedicated code for persistent (idiopathic) toe-walking; it is a gait descriptor captured under MB44 Abnormalities of gait and mobility in Chapter 21. Secondary toe-walking is coded to its underlying cause — cerebral palsy, neuromuscular disorder, contracture or an associated neurodevelopmental condition such as autism (6A02).
A child who walks on their toes long past toddlerhood prompts a fair question — what does ICD-11 actually call this?
In short
Persistent (idiopathic) toe-walking has no dedicated diagnostic code in ICD-11 — it is a clinical descriptor of gait, not a disease entity. When coding is required, it is captured under the gait and mobility abnormality category MB44 Abnormalities of gait and mobility, with MB44.2 Abnormal posture or the broader gait descriptors applied as clinically appropriate. The label "idiopathic" applies only once neurological, orthopaedic and neurodevelopmental causes are excluded.The classification, precisely
ICD-11 treats toe-walking as a functional sign within Chapter 21 (Symptoms, signs or clinical findings, not elsewhere classified), under MB44 Abnormalities of gait and mobility. Two coding principles matter:- Idiopathic toe-walking — a diagnosis of exclusion — is recorded via the relevant gait-abnormality descriptor, as ICD-11 offers no specific stem code for it.
- Secondary toe-walking should instead be coded to its underlying aetiology where one is identified: cerebral palsy (Chapter 8, diseases of the nervous system), neuromuscular disorders, a tendoachilles contracture (musculoskeletal chapter), or association with neurodevelopmental conditions including autism spectrum disorder (6A02). In these cases the underlying condition, not the gait sign, drives the primary code.
Clinically this distinction is the whole point: the code follows the cause. A persistent toe-walker therefore warrants assessment of dorsiflexion range, tone, deep-tendon reflexes, developmental history and any sensory or communication differences before "idiopathic" is justified.
When to refer
Refer for assessment when toe-walking persists beyond age 2, is unilateral, is accompanied by limited ankle dorsiflexion, tightness or contracture, regression, hypertonia, or co-occurring speech, social-communication or sensory differences. These point toward a neurological or neurodevelopmental contributor rather than benign idiopathic gait.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 descriptor or code. Where gait sits alongside developmental differences, a structured profile clarifies whether the toe-walking is isolated or part of a broader picture worth supporting.

What to watch
Toe-walking persisting beyond age 2, unilateral gait, limited ankle dorsiflexion or contracture, hypertonia, regression, or co-occurring speech, social-communication or sensory differences.

Note whether the child can stand and walk flat-footed when asked or distracted — voluntary heel-strike on request points away from a fixed contracture and helps frame the referral.

Frequently asked
Does ICD-11 have a specific code for idiopathic toe-walking?
No. ICD-11 provides no dedicated stem code for idiopathic toe-walking. It is recorded as a gait descriptor under MB44 Abnormalities of gait and mobility within Chapter 21 (symptoms, signs and clinical findings).
How is secondary toe-walking coded?
Secondary toe-walking is coded to its underlying cause — for example cerebral palsy, a neuromuscular disorder, a tendoachilles contracture, or an associated neurodevelopmental condition such as autism spectrum disorder (6A02). The aetiology drives the primary code, not the gait sign.
When should persistent toe-walking be referred?
Refer when it persists beyond age 2, is unilateral, shows limited ankle dorsiflexion or contracture, hypertonia, regression, or occurs alongside speech, social-communication or sensory differences — all of which suggest a neurological or neurodevelopmental contributor.
