Name of the Condition

• Gastrointestinal Anthrax (ICD Code: A22.2)

Summary

• Gastrointestinal anthrax is a rare bacterial infection caused by consuming undercooked or contaminated meat from infected animals. It affects the digestive system and can lead to severe systemic symptoms if not treated promptly.

Causes

• The condition is caused by ingestion of Bacillus anthracis spores, often through contaminated meat from infected livestock.

Risk Factors

• Eating undercooked or raw meat from livestock in regions where anthrax is more common.
• Occupational exposure for workers handling animal products.

Symptoms

• Nausea, vomiting, and loss of appetite.
• Abdominal pain, fever, and diarrhea, which may be bloody.
• Severe cases may involve swelling of the abdominal area and ascites.

Diagnosis

• Confirmed through culture and molecular testing of blood or stool samples.
• Imaging studies, such as abdominal CT scans, may help assess intestinal damage.

Treatment Options

• Early stages: Antibiotics (e.g., Ciprofloxacin, Doxycycline) can be effective in treating the infection.
• Advanced cases may require intravenous antibiotics and supportive care to manage complications.

Prognosis and Follow-Up

• Prognosis improves with early diagnosis and treatment, but delays can result in severe complications or death.
• Regular follow-up is crucial to ensure bacterial eradication and monitor for any adverse effects.

Complications

• If untreated, gastrointestinal anthrax can lead to sepsis, intestinal perforation, and massive internal bleeding.
• Long-term organ damage is possible after severe infections.

Lifestyle & Prevention

• Avoiding consumption of undercooked or raw meat, especially in endemic areas.
• Implementing occupational safety measures for those working with animals or animal products.

When to Seek Professional Help

• Immediate medical attention is necessary for sudden onset abdominal pain, fever, nausea, and vomiting, especially after suspected exposure to contaminated meat.

Tips for Medical Coders

• Ensure accurate documentation of symptoms and laboratory confirmation for precise ICD coding under A22.2.
• Be vigilant about distinguishing gastrointestinal anthrax from other types of anthrax infections to avoid miscoding.
