ICD-10 Code G80.8 – Other cerebral palsy (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G80.8 – Other cerebral palsy
What it is
G80.8 identifies cerebral palsy that does not fit the more specific ICD-10 categories. Use it for a chronic motor disorder arising from early brain injury or abnormal brain development when the type is not otherwise specified.
Clinical signs
Clinical features vary; refer to documentation. Common findings include persistent abnormal muscle tone, impaired posture, and movement difficulty, but the specific pattern may be mixed or atypical.
When to use this code
Use this code when the record states cerebral palsy and the provider documents a form not classified as spastic, dyskinetic, ataxic, or another named subtype. It also fits cases where the subtype is unclear, mixed, or otherwise described without a more specific code. Check documentation if the note includes laterality or a more precise motor pattern.
Do not use for
Do not use G80.8 when the documentation supports a more specific cerebral palsy code. Do not assign it for transient motor problems or for weakness from another neurologic, muscular, or orthopedic condition.
Coding tip
Choose the most specific cerebral palsy code available; use G80.8 only when the provider does not document a better-defined subtype.
