K55.029 Acute infarction of small intestine, extent unspecified

Name of the Condition

• Acute Infarction of Small Intestine, Extent Unspecified
• ICD-10 Code: K55.029

Summary

Acute infarction of the small intestine, extent unspecified, is a sudden reduction in blood flow leading to tissue death (infarction) in the small bowel, where the specific extent of involvement is not detailed. This condition requires urgent medical attention to prevent life-threatening complications.

Causes

Sudden occlusion of blood vessels supplying the small 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.
• Bowel obstruction.
• Long-term digestive dysfunction.

Lifestyle & Prevention

• Manage cardiovascular risk factors (e.g., hypertension, diabetes).
• Stay hydrated, especially during illness or after surgery.
• Avoid medications that may reduce intestinal blood flow without medical supervision.
• Seek prompt care for abdominal pain or related symptoms.

When to Seek Professional Help

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

Tips for Medical Coders

Document the extent of intestinal involvement when available, as this may impact code specificity. For K55.029, ensure clinical notes confirm acute infarction of the small intestine without specifying the extent. Include details on vascular compromise, imaging findings, or surgical interventions to support accurate coding.
