Laceration of superior mesenteric vein, initial encounter

📋Clinical Description

This code signifies a tear or cut in the superior mesenteric vein, a major blood vessel that drains blood from the small intestine and part of the large intestine. Such an injury can lead to significant internal bleeding and compromise blood flow from the intestines, potentially causing ischemia or infarction.

🎯When to Use

This code is appropriate for documenting an acute injury to the superior mesenteric vein, typically resulting from blunt or penetrating abdominal trauma. It should be used for the initial treatment of the laceration, such as during emergency department visits or initial hospitalization.

💡Coding Tips

Always ensure documentation specifies "laceration" of the superior mesenteric vein, not just a general injury.
Verify that this is the patient's initial encounter for this specific injury; subsequent encounters will require a different seventh character.
Look for associated injuries to abdominal organs, which are common with superior mesenteric vein trauma, and code them separately.
