Irradiation cystitis with hematuria

This code signifies inflammation of the bladder lining specifically caused by radiation therapy, where the patient is also experiencing blood in their urine. This condition is a known complication of pelvic radiation, often presenting with symptoms such as dysuria, frequency, urgency, and macroscopic or microscopic hematuria.

Apply this code when documentation clearly indicates cystitis resulting from prior radiation treatment, and the patient's presenting symptoms or diagnostic findings include hematuria. This code is appropriate for both acute and chronic forms of radiation-induced cystitis with this specific symptom.

• Always confirm the causal link between radiation therapy and the cystitis.
• Do not use this code for radiation cystitis without documented hematuria; a different subcategory would apply.
• Consider sequencing this code after the primary malignancy if the radiation was for cancer treatment, or after a code for the adverse effect of radiation if applicable.
