Acute cystitis with hematuria

This code signifies an acute inflammation of the urinary bladder, specifically when the patient presents with blood in the urine. It indicates a sudden onset of bladder infection accompanied by the presence of red blood cells in the urine, which may be macroscopic (visible) or microscopic.

Apply this code when documentation explicitly states acute cystitis and also notes the presence of hematuria. This is commonly seen in cases of uncomplicated urinary tract infections where a urinalysis confirms blood in the urine. Supporting documentation includes physician notes detailing symptoms, physical exam findings, and laboratory results (e.g., urinalysis showing positive blood).

• Ensure documentation clearly distinguishes between acute and chronic cystitis; this code is specific to acute presentations.
• Do not use this code if hematuria is the only symptom without a confirmed diagnosis of acute cystitis.
• Review the medical record for any underlying causes of hematuria that may require additional coding.
