Other cystitis without hematuria

This code signifies inflammation of the bladder (cystitis) due to causes other than infection, trauma, or radiation, where there is no presence of blood in the urine. It encompasses various forms of non-infectious cystitis that do not manifest with hematuria.

Apply this code when documentation specifies a diagnosis of cystitis that is explicitly stated as not being infectious, interstitial, or radiation-induced, and the patient's urinalysis or clinical presentation confirms the absence of hematuria. This is appropriate for conditions like chemical cystitis or allergic cystitis without blood in the urine.

• Ensure documentation clearly states the absence of hematuria; otherwise, a more specific code for cystitis with hematuria may be appropriate.
• Distinguish from N30.1- (Interstitial cystitis) and N30.4- (Radiation cystitis), which have their own specific codes.
• Always look for a more specific etiology of the cystitis if documented (e.g., drug-induced, allergic) before defaulting to this "other" category.
