B37.82 Candidal enteritis

Name of the Condition

• Candidal Enteritis (ICD Code: B37.82)
• Technical term: Candidal enteritis
• ICD-10 Code: B37.82

Summary

Candidal enteritis is a fungal infection of the small intestine caused by Candida species, typically resulting from the overgrowth of yeast in the intestinal mucosa. It leads to inflammation and may cause gastrointestinal symptoms, particularly in individuals with predisposing factors. The condition can range from mild to severe, depending on the host's immune status and the extent of fungal proliferation.

Causes

Candidal enteritis occurs when Candida fungi, normally present in the gastrointestinal tract, overgrow in the intestinal lining. This overgrowth is often triggered by disruptions to the body's microbial balance, such as antibiotic use, immunosuppression, or conditions that impair intestinal motility. Invasive forms may arise from hematogenous spread or direct extension from adjacent sites.

Risk Factors

• Weakened immune system (e.g., HIV/AIDS, chemotherapy, immunosuppressive therapy).
• Prolonged use of broad-spectrum antibiotics or corticosteroids.
• Diabetes mellitus or poorly controlled blood sugar.
• Malabsorption syndromes or intestinal surgery.
• Indwelling medical devices (e.g., feeding tubes).
• Chronic gastrointestinal conditions (e.g., inflammatory bowel disease).

Symptoms

• Abdominal pain or cramping.
• Diarrhea, which may be watery or contain mucus.
• Nausea or vomiting.
• Bloating or gas.
• Loss of appetite or weight loss.
• Fatigue or malaise.

Diagnosis

Diagnosis involves a combination of clinical evaluation, stool studies (e.g., fungal cultures or microscopy), and sometimes endoscopic examination with biopsy. Laboratory tests may identify Candida species in stool samples, while imaging or endoscopy can assess intestinal inflammation or structural changes. Clinical correlation with risk factors is essential for confirmation.

Treatment Options

Treatment typically includes antifungal medications, such as fluconazole or amphotericin B, tailored to the severity and underlying cause. Supportive care, such as hydration and electrolyte management, may be necessary for symptomatic relief. Addressing predisposing factors, like discontinuing antibiotics or optimizing immune function, is critical to prevent recurrence.

Prognosis and Follow-Up

Prognosis depends on the individual's overall health and the promptness of treatment. Most cases resolve with appropriate antifungal therapy, especially in immunocompetent patients. Follow-up may involve monitoring symptoms and repeat testing if recurrence is suspected. Immunocompromised individuals may require longer treatment and closer surveillance.

Complications

• Severe dehydration from persistent diarrhea.
• Malnutrition or weight loss due to chronic symptoms.
• Invasive candidiasis spreading to other organs (rare but serious).
• Recurrent infections if underlying risk factors persist.

Lifestyle & Prevention

• Maintain good hygiene and avoid unnecessary antibiotic use.
• Manage chronic conditions like diabetes to control blood sugar.
• Stay hydrated and eat a balanced diet to support gut health.
• Practice safe food handling to reduce infection risk.
• Follow medical advice for device care (e.g., feeding tubes) to minimize fungal exposure.

When to Seek Professional Help

Seek medical attention if symptoms worsen, persist beyond a few days, or include high fever, severe abdominal pain, or signs of dehydration (e.g., dizziness, reduced urination). Immunocompromised individuals should consult a healthcare provider promptly at the onset of symptoms.

Tips for Medical Coders

Document the clinical findings, diagnostic methods, and treatment provided to support the diagnosis of candidal enteritis. Ensure the code B37.82 is used when the infection is specifically localized to the small intestine, with clear differentiation from other gastrointestinal candidiasis subtypes. Include details on risk factors or underlying conditions that may influence coding accuracy.
