ICD Code G24.01

ICD code G24.01 is drug-induced subacute dyskinesia, a movement disorder caused by medication, characterized by involuntary, repetitive movements that develop over a subacute period.

1. Presence of involuntary, repetitive, and purposeless movements (such as grimacing, tongue movements, lip smacking, or rapid eye blinking) that develop after exposure to a medication.

2. Onset of symptoms occurs subacutely, typically days to weeks after initiation or change in dosage of a causative drug.

3. History of recent use of medications known to cause dyskinesia, such as antipsychotics or other dopamine receptor blocking agents.

4. Absence of similar movement disorder symptoms prior to drug exposure.

5. Symptoms are not better explained by another neurological or medical condition.

6. Symptoms persist beyond the expected duration of acute drug effects but do not meet criteria for chronic or tardive dyskinesia.
