Diagnosis Overview

What is Atrioventricular Fistula Malfunction?
Essential facts and insights about Atrioventricular Fistula Malfunction

Key Clinical Considerations:

  • Decreased blood flow through the fistula
  • Signs of infection or thrombosis
  • Symptoms of heart failure or volume overload

Clinical Information

Clinical Criteria & Documentation Requirements

  • Patient history of dialysis access
  • Details of physical examination findings
  • Results of imaging studies (e.g., ultrasound)

Coding Guidelines

Usage Guidelines & Examples

  • Follow guidelines for coding complications of vascular access.
  • Common errors include misclassifying the type of malfunction.

Code Exclusions

Important Exclusions

  • Arteriovenous malformation (AVM)
  • Other vascular access complications not related to fistula malfunction
