ICD-10 Code G25.79 – Other drug induced movement disorders (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G25.79 – Other drug induced movement disorders
What it is
G25.79 identifies movement disorders caused by a drug or medication that do not fit a more specific code. Use it when documentation links abnormal movements to a medication exposure and the exact type is not otherwise classified.
Clinical signs
Clinical features vary; refer to documentation. Commonly reported findings include involuntary movements such as tremor, dyskinesia, dystonia, or akathisia after drug exposure, with improvement often noted when the drug is stopped or changed.
When to use this code
Use this code when the provider documents a movement disorder caused by a medication, toxin, or other drug effect and no more specific drug-induced movement disorder code applies. It is appropriate for clearly linked adverse drug reactions documented in the record. Check documentation if the causative agent or movement type is unclear.
Do not use for
Do not use this code for movement disorders unrelated to drug exposure, such as idiopathic Parkinson disease or essential tremor. If a more specific drug-induced movement disorder is documented, code that condition instead.
Coding tip
Capture both the movement disorder and the responsible drug in the record whenever possible.
