Trigonitis

This code represents inflammation specifically affecting the trigone region of the bladder. It is a localized form of cystitis, often characterized by irritation and discomfort in the lower urinary tract.

Use this code when documentation explicitly states "trigonitis" as the diagnosis. This diagnosis is typically supported by cystoscopic findings revealing inflammation localized to the bladder trigone, often with symptoms such as dysuria, frequency, and urgency.

• Ensure documentation specifies "trigonitis" rather than general cystitis.
• Do not use for generalized bladder inflammation; reserve for trigone-specific involvement.
• Consider additional codes for any underlying causes or associated conditions, such as infection.
