What condition is referred to as inflammation of the urinary bladder?

The condition referred to as inflammation of the urinary bladder is cystitis. Cystitis occurs when the bladder becomes irritated and swollen, often due to infection. Common symptoms associated with this condition include frequent urination, a strong urge to urinate, pain during urination, and lower abdominal discomfort.

Understanding cystitis is crucial, particularly within an inpatient coding context, as it is commonly encountered in clinical settings, and accurate coding plays a significant role in patient management and billing. Knowing the specific diagnosis helps in determining the appropriate treatment and can also indicate underlying causes, such as urinary tract infections.

The other terms listed relate to different urinary complications. Nocturia refers to the need to wake up during the night to urinate, renal calculi are kidney stones causing pain and obstruction, and hematuria is the presence of blood in the urine, which can indicate various underlying issues, but none of these specifically refer to inflammation of the bladder like cystitis does.
