ICD-11 Classification for Cerebral Palsy (8D20)

Coding cerebral palsy correctly is the first step toward a functioning-led plan — ICD-11 makes that cleaner than ever.

In short

In ICD-11-MMS, Cerebral Palsy is classified under code 8D20, within the chapter on diseases of the nervous system. It is defined as a group of permanent, non-progressive disorders of movement and posture attributed to a disturbance in the developing fetal or infant brain. The motor lesion is static, though its clinical expression evolves with growth — which is why ICD-11 coding is best paired with an ICF functioning profile to capture real-world capability.

The ICD-11 structure

8D20 Cerebral palsy sits in the neurodevelopmental motor domain and resolves into recognised subtypes for clinical specificity:

• Spastic cerebral palsy — unilateral or bilateral distribution
• Dyskinetic cerebral palsy — dystonic or choreo-athetotic patterns
• Ataxic cerebral palsy
• Other and unspecified cerebral palsy

Key coding considerations for the clinician:

• CP is a clinical descriptor of a static encephalopathy; code the underlying aetiology (e.g. perinatal hypoxic-ischaemic injury, periventricular leukomalacia) separately where known.
• Comorbidities — epilepsy, intellectual developmental disorder, communication and feeding difficulties, visual or hearing impairment — are coded in addition, not subsumed.
• ICD-11 captures the diagnosis; the WHO ICF captures functioning (e.g. GMFCS-aligned mobility, communication, self-care). The two together drive the therapy plan.

When to refer

CP is recognised through early motor asymmetry, persistent abnormal tone, delayed or atypical motor milestones, and retained primitive reflexes. Early referral to coordinated paediatric neurology and developmental therapy services is the priority — earlier engagement supports better functional trajectories.

The Pinnacle way

AbilityScore® is part of Pinnacle’s developmental assessment. Diagnosis, where needed, requires an appropriately qualified healthcare professional — never from a code lookup or an online form. ICD-11 8D20 names the condition; our structured, clinician-administered AbilityScore® maps the child's functioning so therapy targets what matters day to day.
