K57.31 Diverticulosis of large intestine without perforation or abscess with bleeding

Name of the Condition

• Diverticulosis of Large Intestine Without Perforation or Abscess With Bleeding

Summary

Diverticulosis of the large intestine refers to the presence of diverticula—small, bulging pouches in the colon lining—without inflammation, perforation, or abscess formation. This specific code applies when bleeding is present, distinguishing it from uncomplicated diverticulosis without bleeding. It represents a subset of diverticular disease where the primary concern is hemorrhage from the diverticula.

Causes

The exact cause of diverticulosis is not fully understood, but it is often linked to increased pressure within the colon, which can lead to the formation of diverticula. Factors such as a low-fiber diet, chronic constipation, and aging may contribute to this pressure and the development of the condition. Bleeding may occur when a diverticulum erodes into a blood vessel.

Risk Factors

• Age (more common in individuals over 50)
• Low-fiber diet
• Obesity
• Sedentary lifestyle
• Smoking
• Certain medications (e.g., NSAIDs, steroids)
• Family history of diverticular disease

Symptoms

• Abdominal pain (often lower left side for colon involvement)
• Bright red or maroon blood in stool
• Bloating or gas
• Changes in bowel habits (constipation or diarrhea)
• Fatigue (if bleeding is significant)

Diagnosis

Diagnosis typically involves a combination of clinical evaluation, including a physical examination and review of symptoms. Imaging studies such as a CT scan or colonoscopy may be used to confirm the presence of diverticula and assess for bleeding. Stool tests or blood work may help evaluate the extent of blood loss.

Treatment Options

Treatment focuses on managing bleeding and preventing recurrence. This may include dietary modifications (increased fiber), medications to control bleeding (e.g., anti-inflammatory drugs), and in severe cases, procedures like colonoscopy to cauterize the bleeding site. Hospitalization may be necessary for significant bleeding.

Prognosis and Follow-Up

Most cases of diverticulosis with bleeding resolve with treatment, but recurrence is possible. Follow-up care often involves monitoring for further bleeding and adjusting lifestyle factors to reduce risk. Regular colonoscopies may be recommended to assess diverticula and prevent complications.

Complications

• Significant blood loss leading to anemia
• Recurrent bleeding
• Infection or inflammation (diverticulitis)
• Obstruction of the colon (rare)

Lifestyle & Prevention

• Increase dietary fiber intake (fruits, vegetables, whole grains)
• Stay hydrated to promote regular bowel movements
• Maintain a healthy weight
• Exercise regularly to support digestive health
• Avoid straining during bowel movements

When to Seek Professional Help

Seek immediate medical attention if you experience:

• Large amounts of blood in stool
• Dizziness, fainting, or signs of shock
• Severe abdominal pain
• Persistent or worsening bleeding

Tips for Medical Coders

When coding K57.31, ensure documentation confirms diverticulosis of the large intestine without perforation or abscess, with bleeding. Verify that the bleeding is associated with the diverticula and not another cause. Document the location (e.g., colon) and any contributing factors (e.g., low-fiber diet) to support accurate coding.
