Acute cystitis without hematuria

This code represents an acute inflammation of the urinary bladder, typically caused by a bacterial infection, without the presence of blood in the urine. Patients commonly experience symptoms such as dysuria, urinary frequency, urgency, and suprapubic pain. It is a common form of urinary tract infection (UTI).

Use this code when documentation clearly indicates a diagnosis of acute cystitis and explicitly states the absence of hematuria. This applies to initial encounters and subsequent visits where acute cystitis without hematuria is the primary or secondary diagnosis. Supporting documentation includes physician notes detailing symptoms, physical exam findings, and laboratory results (e.g., urinalysis, urine culture) confirming infection without red blood cells.

• Ensure documentation explicitly negates hematuria; otherwise, a code specifying hematuria (e.g., N30.01) would be more appropriate.
• Do not use this code for chronic cystitis; refer to codes within the N30.1-N30.4 range for those conditions.
• If an infectious agent is identified, consider coding the organism as an additional diagnosis (e.g., B95-B97 series) to provide greater specificity.
