ICD-10 Code G24.01 – Drug induced subacute dyskinesia (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G24.01 – Drug induced subacute dyskinesia
What it is
G24.01 identifies a medication-related movement disorder with involuntary, abnormal movements that develop after drug exposure. Use it when documentation clearly links the dyskinesia to a prescribed or administered drug.
Clinical signs
Typical findings include repetitive, purposeless movements, often affecting the face, tongue, jaw, trunk, or limbs. Clinical features vary; refer to documentation for the specific movement pattern and drug association.
When to use this code
Use this code when the record states subacute dyskinesia is caused by a medication or other drug exposure. It is appropriate when the clinician documents a drug-induced movement disorder rather than an idiopathic or neurologic dyskinesia.
Confirm the causal drug relationship in the chart, especially when symptoms appear after starting or changing therapy. If the cause is unclear, check documentation before coding this diagnosis.
Do not use for
Do not use G24.01 for dyskinesia without a documented drug cause, or for other movement disorders such as tremor, chorea, or dystonia. Check documentation if the terminology is nonspecific.
Coding tip
Look for explicit provider wording such as “drug induced” or “medication-related” to support code selection.
