K55.061 Focal (segmental) acute infarction of intestine, part unspecified

Name of the Condition

• Focal (Segmental) Acute Infarction of Intestine, Part Unspecified
• ICD-10 Code: K55.061

Summary

Focal (segmental) acute infarction of the intestine, part unspecified, refers to localized tissue death in a segment of the intestinal tract due to sudden loss of blood supply. This condition requires prompt evaluation to prevent progression to severe complications.

Causes

Sudden occlusion or disruption of blood flow to a specific intestinal segment can result from arterial or venous thrombosis, embolism, or non-occlusive ischemia. Underlying mechanisms may include vascular blockages, reduced perfusion, or external compression.

Risk Factors

• Advanced age.
• Cardiovascular disease.
• Recent abdominal surgery or trauma.
• Dehydration or hypotension.
• Medications affecting vascular tone.

Symptoms

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

Diagnosis

Clinical assessment, imaging (e.g., CT angiography), and laboratory tests help identify vascular compromise. Endoscopy may evaluate 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.
• Chronic intestinal 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.

When to Seek Professional Help

Seek immediate medical attention for sudden, severe abdominal pain, persistent vomiting, or bloody stools.

Tips for Medical Coders

Document the specific intestinal segment (if known) and confirm acute infarction. Ensure clinical correlation with imaging or endoscopic findings to support the diagnosis.
