T82.520 Displacement of surgically created arteriovenous fistula

Name of the Condition

• Displacement of Surgically Created Arteriovenous Fistula

Summary

This condition describes the displacement or shifting of an arteriovenous fistula (AV fistula) that was surgically created, typically for hemodialysis in patients with renal failure. The displacement can impair the fistula’s functionality, potentially affecting its ability to support dialysis.

Causes

Displacement may result from improper surgical technique, trauma to the fistula site, physical activities that strain the area, or poor wound healing processes.

Risk Factors

• Recent surgery for fistula creation
• Underlying connective tissue disorders
• Activities or situations that increase pressure or strain on the fistula site

Symptoms

Typical symptoms include swelling, pain, and decreased functionality of the fistula, which might manifest as inadequate blood flow for dialysis. Visible moving or shifting of the fistula may also be observed.

Diagnosis

Diagnosis generally involves physical examination and imaging studies such as ultrasound or angiography to assess the position and functionality of the fistula.

Treatment Options

Treatment may include repositioning the fistula through surgical intervention, rest and immobilization of the affected area, and in some cases, the use of compression bandages.

Prognosis and Follow-Up

With timely intervention, most patients recover well. However, follow-up with regular checks is crucial to ensure fistula stability and proper function.

Complications

Potential complications include infection, thrombosis, or complete loss of fistula function, which may require further intervention.

Lifestyle & Prevention

• Avoid activities that strain the fistula site
• Follow post-surgical care instructions carefully
• Report any changes in fistula appearance or function promptly

When to Seek Professional Help

Seek medical attention if you experience increased swelling, pain, or signs of reduced blood flow, such as coolness or discoloration of the affected limb.

Tips for Medical Coders

Document the clinical findings supporting the displacement, including imaging results and physical examination details. Ensure the code T82.520 is used when the displacement of a surgically created AV fistula is confirmed and documented.
