ICD-10 Code G24.09 – Other drug induced dystonia (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G24.09 – Other drug induced dystonia
What it is
G24.09 identifies dystonia caused by a drug or medication, other than the more specific drug-induced movement disorder codes. It refers to involuntary, sustained muscle contractions that produce abnormal postures or twisting movements.
Clinical signs
Clinical features vary; refer to documentation. Common findings include abnormal neck, facial, jaw, tongue, or limb posturing, with symptoms developing after exposure to a causative medication.
When to use this code
Use this code when the record clearly links dystonia to a medication and the provider documents it as drug induced. It is appropriate when the type of drug-induced dystonia is not coded elsewhere in ICD-10-CM. Check documentation for the offending agent and the temporal relationship.
Do not use for
Do not use this code if the dystonia is due to another known cause, such as a primary neurologic disorder or another specified movement disorder. Do not use it when the documentation does not support a drug cause.
Coding tip
Confirm both the dystonia diagnosis and the medication link in the provider note before assigning G24.09.
