ICD-10 Code G24 – Dystonia (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G24 – Dystonia
What it is
Dystonia is a movement disorder marked by involuntary muscle contractions that cause twisting movements or abnormal postures. Use G24 for the documented dystonia diagnosis when the record does not specify a more precise subtype.
Clinical signs
Clinical features vary; refer to documentation. Common findings include sustained or intermittent muscle contractions, repetitive movements, and abnormal positioning of the neck, limbs, face, or voice.
When to use this code
Use this code when the provider documents dystonia without naming a specific form, such as cervical dystonia or drug-induced dystonia. It also fits cases where the note confirms a dystonic movement disorder but lacks further detail. Check documentation if another cause or subtype is stated.
Do not use for
Do not use G24 for tremor, chorea, or spasticity unless dystonia is clearly documented. If the record specifies a different neurologic movement disorder or a secondary cause with a more exact code, code that instead.
Coding tip
Look for the exact dystonia subtype and any documented cause, because a more specific ICD-10-CM code may apply.
