In simple words: This code represents other types of bladder infections/inflammations not otherwise specified.

Other cystitis encompasses various forms of bladder inflammation not classified elsewhere, including abscesses within the bladder wall.

Example 1: A patient presents with lower abdominal pain, frequent urination, and cloudy urine. After ruling out common infections, an abscess in the bladder wall is discovered, leading to the diagnosis of other cystitis (N30.8)., A patient undergoing radiation therapy for pelvic cancer develops bladder inflammation as a side effect. This radiation-induced cystitis, not fitting other specific categories, is coded as N30.8., A patient with a history of interstitial cystitis experiences a flare-up with symptoms not aligning with typical infectious or radiation cystitis. This instance, representing another form of bladder inflammation, is classified under N30.8.
