Diagnosis Overview

What is Tremor?
Essential facts and insights about Tremor

Key Clinical Considerations:

  • Involuntary rhythmic shaking of a body part
  • Electromyography (EMG) showing abnormal muscle activity
  • Resting tremor, postural tremor, or intention tremor observed during physical examination

Clinical Information

Clinical Criteria & Documentation Requirements

  • Patient history including onset, duration, and frequency of tremors
  • Specific terminology such as 'resting tremor' or 'essential tremor'
  • Examples of documentation: 'Patient exhibits a 4 Hz resting tremor in the right hand.'

Coding Guidelines

Usage Guidelines & Examples

  • Usage guidelines: Differentiate between essential tremor and tremors due to other neurological conditions.
  • Common errors: Misclassifying tremors as anxiety-related without proper evaluation.

Code Exclusions

Important Exclusions

  • Excluded conditions: Tremors due to metabolic disorders or drug-induced tremors.
  • Alternative codes: Consider G25.2 for drug-induced tremor.
