Irradiation cystitis without hematuria

This code signifies inflammation of the bladder resulting from radiation therapy, specifically in cases where there is no blood present in the urine. It represents a non-hemorrhagic adverse effect of radiation treatment, often seen in patients who have undergone pelvic or abdominal radiation for cancer.

Use this code for patients presenting with symptoms of bladder irritation, frequency, urgency, or dysuria following radiation therapy, and when urinalysis or clinical assessment confirms the absence of hematuria. Documentation should clearly link the cystitis to prior radiation treatment and explicitly state the lack of blood in the urine.

• Ensure documentation specifies "without hematuria" to differentiate from N30.41 (Irradiation cystitis with hematuria).
• Code first the underlying malignancy for which the radiation was administered, if still active.
• Do not use this code for chemical, infectious, or interstitial cystitis; these have distinct ICD-10-CM codes.
