ICD-10 Code G25.8 – Other specified extrapyramidal and movement disorders (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G25.8 – Other specified extrapyramidal and movement disorders
What it is
G25.8 identifies movement disorders affecting muscle control and coordination that do not fit a more specific ICD-10 category. Use it when the chart clearly documents an extrapyramidal or movement disorder, but the exact type is not named.
Clinical signs
Clinical features vary; refer to documentation. You may see involuntary movements, abnormal muscle tone, tremor, rigidity, or other motor control problems noted by the clinician.
When to use this code
Use this code when the provider diagnoses a specified extrapyramidal or movement disorder and no more specific code applies. It is appropriate for documented disorders such as atypical or otherwise specified movement problems. If the record does not name the condition, check documentation before coding.
Do not use for
Do not use G25.8 for Parkinson disease, drug-induced movement disorders, or tremor when a more specific code is documented. If the note describes a known, separately classified movement disorder, choose that code instead.
Coding tip
Code the exact documented movement disorder first; use G25.8 only when the provider’s wording supports “other specified” and no better code is available.
