Cystourethroscopy, with ureteral catheterization, with or without irrigation, instillation, or ureteropyelography, exclusive of radiologic service; with brush biopsy of ureter and/or renal pelvis

Cystourethroscopy is a medical procedure that allows healthcare professionals to visualize the interior of the bladder and urethra. This is achieved through the insertion of a cystoscope, which can be either rigid or flexible, into the urethra. Prior to the procedure, the urethra is typically cleansed with an antiseptic solution to minimize the risk of infection. During the cystourethroscopy, the bladder may be filled with sterile saline, enhancing the visibility of the bladder wall for better examination. Following the inspection of the bladder, the procedure may involve catheterization of the ureters. This process includes the introduction of a guidewire through the cystoscope, which is then advanced into the first ureter and further into the renal pelvis. A catheter is subsequently advanced over the guidewire to reach the renal pelvis. At this stage, the ureter may be irrigated with normal saline, or a diagnostic or therapeutic solution may be instilled. Additionally, contrast material can be injected to facilitate ureteropyelography, which is a separate reportable service. The procedure can be performed on both ureters if necessary. In the context of CPT® Code 52007, the procedure includes the collection of tissue samples from the ureters or renal pelvis using a nylon or steel brush, which is an essential step for diagnostic purposes.
