Arteriovenous malformation of digestive system vessel

📋Clinical Description

This code signifies an abnormal, direct connection between an artery and a vein within the digestive system, bypassing the capillary bed. This congenital vascular anomaly can occur anywhere from the esophagus to the rectum, leading to potential bleeding or other gastrointestinal complications.

🎯When to Use

Use this code for documented arteriovenous malformations (AVMs) affecting organs such as the stomach, small intestine, or colon. This diagnosis is typically supported by endoscopic findings, angiography, or other imaging studies confirming the presence and location of the AVM within the digestive tract.

💡Coding Tips

Differentiate from acquired angiodysplasia, which has a distinct code.
Ensure documentation specifies "malformation" to distinguish from other vascular anomalies.
Consider additional codes for any associated complications, such as gastrointestinal hemorrhage.
