ICD-10 Code G25.0 – Essential tremor (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G25.0 – Essential tremor
What it is
G25.0 identifies essential tremor, a neurologic movement disorder that causes involuntary shaking, usually in the hands. It is typically an action tremor rather than a resting tremor.
Clinical signs
Common findings include bilateral postural or kinetic tremor, often affecting the upper limbs. Head, voice, or other body parts may also be involved; clinical features vary, so refer to documentation.
When to use this code
Use G25.0 when the provider documents essential tremor or benign essential tremor as the diagnosis. Apply it for encounters focused on evaluation, follow-up, or symptom management when the condition is confirmed. If the note only says “tremor” without further detail, check documentation before coding.
Do not use for
Do not use this code for tremor clearly caused by another disorder, medication, or substance. If the diagnosis is unspecified tremor or another movement disorder, choose the documented condition instead.
Coding tip
Code G25.0 only when essential tremor is explicitly documented; otherwise, query or check documentation for the specific tremor type.
