K55.042 Diffuse acute infarction of large intestine

Name of the Condition

• Diffuse Acute Infarction of Large Intestine
• ICD-10 Code: K55.042

Summary

Diffuse acute infarction of the large intestine is a sudden, widespread reduction in blood flow leading to tissue death (infarction) throughout the colon. This condition requires urgent medical attention to prevent life-threatening complications.

Causes

Sudden occlusion of blood vessels supplying the large intestine, such as arterial or venous thrombosis, embolism, or non-occlusive ischemia, can cause infarction. Underlying mechanisms may include blockages, reduced perfusion, or vascular compression.

Risk Factors

• Advanced age.
• Cardiovascular disease.
• Recent abdominal surgery or trauma.
• Dehydration or hypotension.
• Medications affecting blood flow.

Symptoms

• Sudden, severe abdominal pain.
• Nausea or vomiting.
• Bloody stools or melena.
• Abdominal distension.
• Fever or signs of infection.

Diagnosis

Clinical evaluation, imaging (e.g., CT angiography), and laboratory tests help identify vascular compromise. Endoscopy may assess mucosal integrity, and Doppler ultrasound or angiography can confirm infarction.

Treatment Options

• Restoring blood flow through medications or interventions.
• Surgical repair for severe cases.
• Supportive care, including fluid management and infection control.

Prognosis and Follow-Up

Outcomes depend on early intervention and underlying causes. Regular monitoring is essential to detect recurrence or complications.

Complications

• Intestinal necrosis or perforation.
• Sepsis or systemic infection.
• Bowel obstruction or stricture.
• Chronic abdominal pain or functional impairment.

Lifestyle & Prevention

• Maintain cardiovascular health through diet and exercise.
• Stay hydrated, especially during illness or heat exposure.
• Manage chronic conditions like diabetes or hypertension.
• Avoid medications that reduce blood flow without medical supervision.

When to Seek Professional Help

Seek immediate medical attention for sudden, severe abdominal pain, bloody stools, or signs of infection (e.g., fever, chills). Prompt evaluation is critical to prevent irreversible damage.

Tips for Medical Coders

Document the extent (diffuse) and location (large intestine) of the infarction to support accurate coding. Include clinical details confirming acute onset and vascular compromise. Ensure documentation aligns with the specificity of K55.042.
