K55.06 Acute infarction of intestine, part unspecified

Name of the Condition

• Acute Infarction of Intestine, Part Unspecified
• ICD-10 Code: K55.06

Summary

Acute infarction of the intestine, part unspecified, is a sudden, severe reduction in blood flow resulting in tissue death (infarction) in the intestinal tract. This condition requires urgent medical attention to prevent life-threatening complications.

Causes

Sudden occlusion of blood vessels supplying the 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 malabsorption.

Lifestyle & Prevention

• Manage cardiovascular risk factors (e.g., hypertension, diabetes).
• Stay hydrated, especially during illness or heat exposure.
• Avoid medications that reduce blood flow to the intestines without medical supervision.
• Seek prompt care for abdominal pain or digestive 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 irreversible damage.

Tips for Medical Coders

Document the specific intestinal segment (if known) and underlying cause (e.g., thrombosis, embolism) to support accurate coding. Use K55.06 when the infarction location is unspecified. Ensure clinical documentation aligns with the diagnosis to justify code assignment.
