ICD-10 Code G80.4 – Ataxic cerebral palsy (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G80.4 – Ataxic cerebral palsy
What it is
G80.4 identifies ataxic cerebral palsy, a nonprogressive motor disorder caused by early brain injury or abnormal development. It mainly affects balance, coordination, and purposeful movement.
Clinical signs
Typical findings include unsteady gait, poor coordination, tremor, and difficulty with fine motor tasks. Clinical features vary; refer to documentation.
When to use this code
Use G80.4 when the provider documents ataxic cerebral palsy or records cerebral palsy with ataxia as the specific type. It may also apply when the chart clearly describes a congenital or early-onset coordination disorder consistent with ataxic CP. Check documentation for the exact diagnosis wording.
Do not use for
Do not use this code for acquired ataxia, progressive neurologic disease, or nonspecific gait instability without cerebral palsy. If the record only says “cerebral palsy” without type, check documentation.
Coding tip
Code the documented cerebral palsy type exactly; unspecified CP and ataxic CP are not interchangeable.
