Diagnosis Overview

What is Unsteady Gait?
Essential facts and insights about Unsteady Gait

Key Clinical Considerations:

  • Difficulty maintaining balance while walking
  • Increased sway or instability during ambulation
  • Presence of neurological deficits affecting gait

Clinical Information

Clinical Criteria & Documentation Requirements

  • Detailed patient history including onset and duration of symptoms
  • Neurological examination findings related to gait
  • Specific terms like 'ataxia', 'dizziness', or 'dysmetria' used in documentation

Coding Guidelines

Usage Guidelines & Examples

  • Usage guidelines: Use R26.0 for unsteady gait without further specification.
  • Common errors: Misclassifying unsteady gait as a symptom of another condition without proper documentation.

Code Exclusions

Important Exclusions

  • Excludes conditions like vertigo or peripheral neuropathy that may cause similar symptoms.
  • Alternative codes: Consider G25.0 for tremors affecting gait.
