Official Description

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

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

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.

1. Indications

The procedure is indicated for various conditions affecting the ureter, including:

  • Obstruction - Blockages in the ureter that prevent normal urine flow.
  • Stenosis - Narrowing of the ureter that can lead to increased pressure and potential kidney damage.
  • Stricture - Abnormal tightening of the ureter that may require intervention to restore normal function.
  • Other Abnormal Conditions - Any other identified issues within the ureter that necessitate endoscopic evaluation and treatment.

2. Procedure

The procedure involves several key steps, which are detailed as follows:

  • Step 1: Introduction of the Ureteroscope - The ureteroscope is carefully introduced through the established ureterostomy. This allows the physician to visualize the ureter and assess its condition directly.
  • Step 2: Inspection of the Ureter - Once the ureteroscope is in place, the ureter is inspected for any signs of obstruction, stenosis, stricture, or other abnormalities. This visual examination is crucial for determining the appropriate course of action.
  • Step 3: Irrigation and Instillation - The ureter may be irrigated with normal saline to clear any debris. Additionally, diagnostic or therapeutic solutions can be instilled to facilitate treatment or further evaluation.
  • Step 4: Ureteropyelography - If necessary, contrast material may be injected to perform ureteropyelography, which is a separate reportable service that provides imaging of the ureters and kidneys.
  • Step 5: Ureteral Catheterization - Following the visual examination, a ureteral catheter is advanced through the ureteroscope. This step is essential for any subsequent interventions.
  • Step 6: Dilation of Stenosis - If stenosis is identified, a balloon-tipped catheter is introduced to the site of the narrowing. The balloon is inflated to dilate the ureter, and this process may be repeated multiple times to ensure adequate dilation of the stenotic region.
  • Step 7: Conclusion of the Procedure - After all necessary interventions are completed, the ureteroscope and any other instruments are carefully removed from the ureterostomy site.

3. Post-Procedure

Post-procedure care may include monitoring for any complications such as bleeding or infection at the ureterostomy site. Patients may be advised to maintain hydration and report any unusual symptoms, such as increased pain or changes in urine output. Follow-up appointments may be necessary to assess the success of the procedure and to determine if further interventions are required.

51 Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d).
78 Unplanned return to the operating/procedure room by the same physician or other qualified health care professional following initial procedure for a related procedure during the postoperative period: it may be necessary to indicate that another procedure was performed during the postoperative period of the initial procedure (unplanned procedure following initial procedure). when this procedure is related to the first, and requires the use of an operating/procedure room, it may be reported by adding modifier 78 to the related procedure. (for repeat procedures, see modifier 76.)
