ICD-10 Code G80.9 – Cerebral palsy, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G80.9 – Cerebral palsy, unspecified
What it is
G80.9 identifies cerebral palsy when the type is not further specified in the record. It is a nonprogressive disorder of movement and posture caused by an early brain injury or abnormal brain development.
Clinical signs
Clinical features vary; refer to documentation. Common findings include abnormal muscle tone, poor coordination, delayed motor milestones, and persistent motor impairment that is present from childhood.
When to use this code
Use G80.9 when the provider documents cerebral palsy without naming a subtype, such as spastic, dyskinetic, ataxic, or mixed. It also fits when the chart confirms cerebral palsy but the available note does not support a more specific code. Code the documented functional deficits separately when appropriate.
Do not use for
Do not use this code if the record clearly identifies a more specific cerebral palsy type. Do not use it for other neurologic disorders, developmental delay alone, or acquired weakness without a documented cerebral palsy diagnosis.
Coding tip
If the subtype is missing, query for clarification before defaulting to G80.9.
