Diagnosis Overview

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

Key Clinical Considerations:

  • Presence of an unsteady, irregular or asymmetrical walking pattern
  • Difficulty in initiating or maintaining a gait

Clinical Information

Clinical Criteria & Documentation Requirements

  • Detailed description of the patient's gait, including any irregularities or asymmetries
  • Documentation of any underlying conditions causing the abnormal gait

Coding Guidelines

Usage Guidelines & Examples

  • R26.81 is used for other abnormalities of gait and mobility, not elsewhere classified
  • R26.0 is used when the patient is unable to walk, not elsewhere classified

Code Exclusions

Important Exclusions

  • Paralytic gait (G83.3)
  • Spastic gait (G80-G83)

This diagnosis requires careful attention to:

  • Comprehensive clinical documentation
  • Accurate code selection based on clinical criteria
  • Proper exclusion considerations
  • Specialty-specific coding guidelines

Documentation

Billing Information

Billing Considerations

  • Ensure proper documentation for billing
  • Verify code specificity requirements
  • Check for any additional codes needed
  • Review payer-specific guidelines

Common Issues

  • Insufficient clinical documentation

Frequently Asked Questions

What is considered an abnormal gait?

When should this code be used?

This code should be used when a patient presents with an abnormal walking pattern not caused by paralysis or spasticity.
