ICD-10 Code G25.9 – Extrapyramidal and movement disorder, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G25.9 – Extrapyramidal and movement disorder, unspecified
What it is
G25.9 is used for an extrapyramidal or movement disorder when the specific type is not documented. It covers abnormal involuntary movement problems that do not fit a more precise diagnosis.
Clinical signs
Clinical features vary; refer to documentation. You may see tremor, involuntary jerking, rigidity, or other abnormal movements, but the record should support that a movement disorder is present.
When to use this code
Use this code when the provider documents an extrapyramidal or movement disorder but does not name a specific disorder. It is appropriate when the chart lacks enough detail to code a more exact condition. If the note later identifies the disorder, code the specific diagnosis instead.
Do not use for
Do not use G25.9 when the documentation identifies a specific movement disorder such as tremor or dystonia. Do not assign it if the abnormal movement is clearly explained by another documented condition; check documentation.
Coding tip
Choose G25.9 only when the record supports a movement disorder but the provider leaves it unspecified.
