ICD-10 Code G25.6 – Drug induced tics and other tics of organic origin (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G25.6 – Drug induced tics and other tics of organic origin
What it is
This code identifies tic disorders caused by a medication or another organic cause. Use it when the involuntary movements or vocalizations are documented as secondary rather than primary.
Clinical signs
Clinical features may include sudden, repetitive motor tics, vocal tics, or both. Symptoms can be brief, suppressible, and fluctuate; if the cause is unclear, clinical features vary and you should refer to documentation.
When to use this code
Use G25.6 when the record links tics to a drug exposure or another organic etiology. It is appropriate when the clinician documents medication-induced tics, secondary tics, or tics due to a known medical cause. Check documentation if the source is not clearly stated.
Do not use for
Do not use this code for primary tic disorders without an identified organic cause. Do not assign it when the chart only says “tremor,” “spasm,” or another movement disorder without tic documentation.
Coding tip
Code the documented cause first when the record identifies a specific drug or underlying condition.
