Official Description

Renal endoscopy through established nephrostomy or pyelostomy, with or without irrigation, instillation, or ureteropyelography, exclusive of radiologic service; with resection of tumor

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 50562 involves a renal endoscopy performed through an already established nephrostomy or pyelostomy. This procedure is specifically designed for the examination and treatment of tumors located within the kidney. The process begins with the removal of the external drainage bag from the nephrostomy or pyelostomy tube, which is a tube inserted to allow urine to drain from the kidney. A guidewire is then advanced through this tube, facilitating the removal of the tube itself. Following this, a series of dilators are utilized to expand the tract, enabling the insertion of a renal endoscope. This endoscope allows for direct visualization of the kidney, where the physician can locate the tumor. During the procedure, sterile saline or other solutions may be used for irrigation, and diagnostic or therapeutic solutions can be instilled into the kidney. Additionally, contrast material may be introduced for ureteropyelography, which is a separate radiologic service that is not included in this code. Once the tumor is identified, the nephroscope is exchanged for a resectoscope, which is specifically designed for the resection of tissue. The tumor is then carefully resected and removed, with the use of irrigation and an endoscopic evacuation device to manage the surgical site. After the tumor has been excised, the kidney is re-examined to confirm the complete removal of the tumor, and any bleeding is controlled through a process known as fulguration. Finally, the resectoscope is removed, the nephrostomy tube is replaced, and the external drainage bag is reattached, ensuring that the kidney continues to drain properly post-procedure.

1. Indications

The renal endoscopy procedure described by CPT® Code 50562 is indicated for the following conditions:

  • Renal Tumors The primary indication for this procedure is the presence of tumors within the kidney that require examination and potential resection.

2. Procedure

The procedure involves several critical steps to ensure effective examination and treatment of the renal tumor:

  • Step 1: Removal of External Drainage Bag The procedure begins with the careful removal of the external drainage bag from the existing nephrostomy or pyelostomy tube. This step is essential to access the nephrostomy tube for further manipulation.
  • Step 2: Advancement of Guidewire A guidewire is then advanced through the nephrostomy tube. This guidewire serves as a pathway for subsequent instruments and is crucial for the safe removal of the nephrostomy tube.
  • Step 3: Removal of Nephrostomy Tube Following the advancement of the guidewire, the nephrostomy tube is removed. This step allows for the dilation of the tract to facilitate the insertion of the endoscope.
  • Step 4: Dilation of Tract A series of dilators are advanced over the guidewire to dilate the tract. This dilation is necessary to create sufficient space for the renal endoscope to be inserted into the kidney.
  • Step 5: Insertion of Renal Endoscope The renal endoscope is then inserted through the established nephrostomy or pyelostomy tract. This instrument allows for direct visualization of the kidney and the tumor.
  • Step 6: Examination of the Kidney The kidney is carefully examined through the endoscope, and the tumor is located. This step is critical for determining the extent of the tumor and planning the resection.
  • Step 7: Irrigation and Instillation Sterile saline or other solutions may be used to irrigate the kidney. Additionally, a diagnostic or therapeutic solution may be instilled into the kidney, or contrast may be introduced for ureteropyelography, which is a separate service not included in this code.
  • Step 8: Resection of Tumor The nephroscope is exchanged for a resectoscope, which is specifically designed for the resection of tissue. The renal tumor is then resected and removed using irrigation and an endoscopic evacuation device to manage the surgical site effectively.
  • Step 9: Re-examination of the Kidney After the tumor has been excised, the kidney is re-examined to ensure that all of the tumor has been removed. This step is vital for confirming the success of the procedure.
  • Step 10: Control of Bleeding Any bleeding that may occur during the procedure is controlled by fulguration, a technique that uses heat to coagulate blood vessels and minimize blood loss.
  • Step 11: Replacement of Nephrostomy Tube Once the procedure is complete, the resectoscope is removed, and the nephrostomy tube is replaced to ensure continued drainage from the kidney.
  • Step 12: Reattachment of External Drainage Bag Finally, the external drainage bag is reattached to the nephrostomy tube, ensuring that the kidney continues to drain properly post-procedure.

3. Post-Procedure

Post-procedure care involves monitoring the patient for any complications, ensuring that the nephrostomy tube is functioning correctly, and managing any discomfort or pain. Patients may require follow-up imaging to assess the success of the tumor resection and to monitor for any recurrence. It is essential to provide instructions regarding the care of the nephrostomy site and to schedule follow-up appointments for ongoing evaluation.

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).
58 Staged or related procedure or service by the same physician or other qualified health care professional during the postoperative period: it may be necessary to indicate that the performance of a procedure or service during the postoperative period was: (a) planned or anticipated (staged); (b) more extensive than the original procedure; or (c) for therapy following a surgical procedure. this circumstance may be reported by adding modifier 58 to the staged or related procedure. note: for treatment of a problem that requires a return to the operating/procedure room (eg, unanticipated clinical condition), see modifier 78.
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.)
