ICD-10 Code G80.3 – Athetoid Cerebral Palsy (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G80.3 – Athetoid cerebral palsy
What it is
G80.3 identifies athetoid cerebral palsy, a type of cerebral palsy marked by involuntary, writhing movements. It reflects a nonprogressive brain disorder affecting posture and motor control.
Clinical signs
Typical findings include fluctuating muscle tone, slow writhing movements, and difficulty with coordinated voluntary motion. Speech and swallowing problems may occur; clinical features vary, so refer to documentation.
When to use this code
Use G80.3 when the provider documents athetoid cerebral palsy or a clearly equivalent description. Code it for confirmed cerebral palsy with athetoid movement patterns, even if the note also describes associated motor impairment. If the subtype is not specified, check documentation before assigning this code.
Do not use for
Do not use G80.3 for spastic, ataxic, or unspecified cerebral palsy. It is also not appropriate for transient movement disorders or neurologic conditions without documentation of cerebral palsy.
Coding tip
Assign this code only when the subtype is explicitly documented; otherwise, query for clarification or use the unspecified cerebral palsy code if supported.
