Other chronic cystitis without hematuria

This code signifies a persistent, long-term inflammation of the bladder that is not accompanied by blood in the urine. It represents a chronic form of cystitis where the specific cause is not otherwise classified.

Apply this code when documentation indicates chronic bladder inflammation without mention of hematuria, and the etiology is not interstitial, radiation-induced, or tuberculous. This code is appropriate for cases of chronic cystitis where the physician has explicitly ruled out or not documented the presence of gross or microscopic hematuria.

• Ensure documentation specifies "chronic" cystitis and explicitly denies or omits mention of hematuria.
• Do not use this code if the documentation indicates interstitial cystitis (N30.1-) or other specified forms of chronic cystitis.
• If hematuria is present, a more specific code from the N30.21 category (Other chronic cystitis with hematuria) should be used.
