A06.82 Other amebic genitourinary infections

Name of the Condition

• Other amebic genitourinary infections (ICD-10-CM Code: A06.82)

Summary

Other amebic genitourinary infections are extraintestinal manifestations of Entamoeba histolytica infection, affecting structures in the genitourinary system beyond the bladder. These infections result from the parasite invading tissues such as the kidneys, ureters, or reproductive organs, leading to inflammation and potential tissue damage. The condition arises from the spread of the parasite beyond the intestines, typically via the bloodstream or direct extension.

Causes

Other amebic genitourinary infections are caused by the protozoan parasite Entamoeba histolytica. The parasite spreads to genitourinary structures from the intestines, often through the bloodstream or direct extension. Transmission occurs through ingestion of cysts, commonly from contaminated food or water, which invade the intestinal lining and may disseminate to distant sites like the genitourinary tract.

Risk Factors

• Living in or traveling to regions with poor sanitation.
• Consuming contaminated food or water.
• Weakened immune system, which may increase susceptibility to severe disease.
• Close contact with an infected individual or exposure to fecal matter.

Symptoms

• Dysuria (painful urination) or urinary frequency.
• Hematuria (blood in urine) or cloudy urine.
• Lower abdominal or pelvic pain.
• Fever or systemic signs of infection in severe cases.
• Genital pain or discharge, depending on the affected organ.

Diagnosis

Diagnosis involves urine analysis to detect E. histolytica cysts or trophozoites, though this is less common than stool examination. Imaging studies (e.g., ultrasound, CT) may assess for genitourinary involvement, and serological tests can identify antibodies. In some cases, biopsy of affected tissue may confirm the presence of the parasite.

Treatment Options

Treatment typically includes antiparasitic medications, such as metronidazole or tinidazole, to eliminate the parasite. Follow-up therapy with a luminal agent (e.g., paromomycin) may be used to clear intestinal colonization. Supportive care, including hydration and pain management, may be necessary for severe cases.

Prognosis and Follow-Up

With appropriate treatment, prognosis is generally good, though complications can occur if the infection is severe or delayed. Follow-up may include repeat testing to confirm parasite clearance and monitoring for recurrence, especially in immunocompromised individuals.

Complications

• Kidney damage or urinary tract obstruction.
• Chronic genitourinary inflammation.
• Spread to other organs if left untreated.
• Severe systemic infection in immunocompromised patients.

Lifestyle & Prevention

• Avoid consuming untreated water or food in regions with poor sanitation.
• Practice good hygiene, including handwashing after using the restroom or handling food.
• Avoid contact with fecal matter, especially in endemic areas.
• Seek prompt treatment for intestinal amebiasis to prevent dissemination.

When to Seek Professional Help

Seek medical attention if you experience persistent urinary symptoms, unexplained pelvic or abdominal pain, or signs of systemic infection (e.g., fever, fatigue) after potential exposure to contaminated sources.

Tips for Medical Coders

When coding for other amebic genitourinary infections (A06.82), ensure documentation specifies the genitourinary site involved (e.g., kidney, ureter, reproductive organ) to support the diagnosis. Confirm that the infection is attributed to Entamoeba histolytica and not another amebic species, as this may impact code assignment. Review clinical notes for evidence of extraintestinal spread from intestinal amebiasis to justify the code.
