Amebic cystitis

This code signifies an infection of the urinary bladder caused by Entamoeba histolytica, a parasitic amoeba. It represents a rare manifestation of amebiasis where the parasite has invaded the bladder tissue, leading to inflammation and associated urinary symptoms.

Utilize this code when documentation clearly indicates a diagnosis of cystitis specifically attributed to Entamoeba histolytica. This diagnosis is typically supported by microscopic identification of trophozoites or cysts in urine or bladder biopsy, or positive serology in conjunction with clinical signs of cystitis.

• Ensure documentation explicitly links the cystitis to Entamoeba histolytica to avoid coding non-amebic cystitis.
• Do not use this code for general cystitis or other forms of parasitic cystitis; specificity is key.
• Consider sequencing this code after any underlying amebic infection of other sites (e.g., intestinal amebiasis) if present and documented as the primary condition.
