CPT® Code 50953

Ureteral endoscopy through established ureterostomy, with or without irrigation, instillation, or ureteropyelography, exclusive of radiologic service; with ureteral catheterization, with or without dilation of ureter

Ureteral endoscopy is a minimally invasive procedure that involves the examination and treatment of the ureter through an established ureterostomy, which is an opening created surgically to allow urine to exit the body. This procedure utilizes a ureteroscope, a specialized instrument designed to visualize the interior of the ureter. The ureteroscope is introduced through the ureterostomy, allowing the physician to inspect the ureter for any abnormalities such as obstructions, stenosis (narrowing), or strictures (abnormal tightening). During the procedure, the ureter may be irrigated with normal saline to clear any debris or obstructions, and diagnostic or therapeutic solutions can be instilled to aid in treatment. Additionally, contrast material may be injected to perform ureteropyelography, a radiologic examination of the ureters and kidneys, although this imaging service is not included in the CPT® code itself. Following the visual examination, a ureteral catheter is advanced through the ureteroscope to facilitate further treatment. If any stenosis is detected, a balloon-tipped catheter can be introduced to the site of the narrowing and inflated to dilate the ureter. This dilation process may involve multiple inflations and deflations of the balloon until the stenotic area is adequately treated. After the necessary interventions are completed, all instruments are carefully removed, concluding the procedure.
