Diagnosis Overview

What is Neurogenic Bladder?
Essential facts and insights about Neurogenic Bladder

Key Clinical Considerations:

  • Urinary incontinence or retention
  • Urodynamic studies showing detrusor overactivity or underactivity
  • Neurological examination revealing sensory or motor deficits

Clinical Information

Clinical Criteria & Documentation Requirements

  • Patient history of neurological conditions
  • Details of urinary symptoms and their impact on daily life
  • Results of urodynamic testing and imaging studies

Coding Guidelines

Usage Guidelines & Examples

  • Ensure correct application of codes based on specific symptoms and urodynamic findings.
  • Common errors include misclassifying the type of neurogenic bladder.

Code Exclusions

Important Exclusions

  • Urinary incontinence due to non-neurological causes.
  • Alternative codes for urinary retention not related to neurogenic causes.
