K31.82 Dieulafoy lesion (hemorrhagic) of stomach and duodenum

Name of the Condition

• Dieulafoy lesion (hemorrhagic) of stomach and duodenum (ICD-10 Code: K31.82)

Summary

This condition involves a rare vascular abnormality in the stomach or duodenum, characterized by a dilated submucosal artery that can cause significant bleeding. It is a distinct cause of gastrointestinal hemorrhage, often presenting with sudden or recurrent bleeding episodes.

Causes

The lesion arises from a persistent, abnormally large submucosal artery that erodes through the mucosal layer, leading to bleeding. The exact trigger for this vascular anomaly is not fully understood, but it may involve congenital or acquired vascular malformations.

Risk Factors

Risk factors include older age, male gender, and conditions associated with gastrointestinal bleeding, such as hypertension or chronic liver disease. The use of medications like nonsteroidal anti-inflammatory drugs (NSAIDs) or anticoagulants may also increase susceptibility.

Symptoms

Patients may experience sudden, painless gastrointestinal bleeding, which can manifest as hematemesis (vomiting blood), melena (black, tarry stools), or hematochezia (bright red blood in stools). Symptoms can range from mild to life-threatening, depending on the bleeding severity.

Diagnosis

Diagnosis typically involves endoscopy, which can identify the characteristic lesion as a small, protruding vessel with active or recent bleeding. Angiography or CT angiography may be used to confirm the vascular nature of the lesion if endoscopy is inconclusive.

Treatment Options

Treatment focuses on controlling bleeding, often through endoscopic methods such as clipping, coagulation, or injection therapy. In severe cases, transcatheter arterial embolization or surgery may be required to address the lesion and prevent recurrence.

Prognosis and Follow-Up

With prompt treatment, the prognosis is generally good, though recurrent bleeding can occur. Follow-up endoscopy may be recommended to monitor for recurrence, especially in high-risk patients.

Complications

Complications include significant blood loss leading to anemia or hypovolemic shock, and rare instances of perforation during endoscopic or surgical intervention.

Lifestyle & Prevention

Avoiding NSAIDs and other medications that increase bleeding risk may help reduce the likelihood of exacerbating the lesion. Maintaining overall gastrointestinal health through balanced diet and regular medical check-ups is advisable.

When to Seek Professional Help

Seek immediate medical attention for symptoms of gastrointestinal bleeding, such as vomiting blood, black stools, or dizziness, as these may indicate a life-threatening condition.

Tips for Medical Coders

Document the location (stomach or duodenum) and presence of hemorrhage to support the K31.82 code. Ensure clinical notes specify the lesion’s identification and any interventions performed, as these details are critical for accurate coding and reimbursement.
