ICD-10 Code G25.61 – Drug Induced Tics (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G25.61 – Drug induced tics
What it is
Use this code for tics that begin or worsen because of a medication or other drug exposure. The movement is involuntary and may be motor, vocal, or both.
Clinical signs
Tics are sudden, brief, repetitive movements or sounds that may be partially suppressible. Clinical features vary; refer to documentation for the suspected drug cause and the observed tic pattern.
When to use this code
Assign G25.61 when the record clearly links the tic disorder to a medication, substance, or drug effect. Use it when the provider documents drug-induced tics, medication-related tics, or similar wording. Check documentation if the cause is uncertain or if another movement disorder is described.
Do not use for
Do not use this code for Tourette syndrome, chronic tic disorders, or nonspecific involuntary movements without a drug cause. If the chart does not support medication causation, check documentation.
Coding tip
Code the drug-induced tic diagnosis only when the provider documents causation; otherwise, code the symptom or underlying condition as recorded.
