Other chronic cystitis

This code signifies a persistent, long-standing inflammation of the bladder that is not specifically classified as interstitial cystitis or other specified forms. It represents a chronic inflammatory process affecting the bladder wall, often leading to recurrent urinary symptoms.

Use this code when documentation indicates a diagnosis of chronic cystitis without further specification, or when other specified forms of chronic cystitis (e.g., interstitial) have been ruled out. This code is appropriate for patients experiencing ongoing bladder inflammation not attributable to acute infection.

• Ensure documentation clearly states "chronic" and not "acute" cystitis.
• Differentiate from interstitial cystitis (595.1) if the physician specifies that diagnosis.
• Look for associated symptoms like frequency, urgency, dysuria, and pelvic pain that persist over an extended period.
