ICD-10 Code G25.1 – Drug-induced tremor (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G25.1 – Drug-induced tremor
What it is
G25.1 identifies tremor caused by a medication or other drug exposure. Use it when the shaking is documented as a direct effect of the substance, not as a separate primary movement disorder.
Clinical signs
Clinical features vary; refer to documentation. Typical findings include rhythmic shaking, often involving the hands or arms, that begins or worsens after drug use and may improve when the medication is stopped.
When to use this code
Use this code when the provider documents tremor as drug-induced, medication-related, or a toxic effect of a substance. It may apply when the note links the tremor to a prescribed drug, overuse, or exposure history. If the cause is not clearly stated, check documentation.
Do not use for
Do not use G25.1 for essential tremor, Parkinsonian tremor, or tremor with no documented drug cause. If the record describes a different neurologic disorder or an unspecified shaking complaint, choose the more accurate code.
Coding tip
Code the tremor only when the chart clearly connects it to a drug; otherwise, you should query the provider.
