Official Description

Nephrectomy, including partial ureterectomy, any open approach including rib resection;

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

An open nephrectomy, as described by CPT® Code 50220, is a surgical procedure that involves the removal of a kidney along with a partial ureterectomy, which is the surgical excision of a portion of the ureter. This procedure is typically performed through a wide flank incision, which is strategically located just below the lower border of the ribs or near the 11th or 12th rib. In some cases, the 11th and/or 12th ribs may need to be resected to provide adequate access to the kidney. Alternatively, surgeons may opt for an anterior subcostal approach, depending on the specific circumstances of the case. During the procedure, the surgeon carefully exposes the kidney and the ureter, isolating the renal artery and vein for ligation and division. This step is crucial for ensuring that the kidney can be safely removed without excessive bleeding. Once the kidney is freed from its surrounding tissues, a section of the ureter is also excised. This involves meticulously dissecting the affected portion of the ureter, dividing it, and removing it along with the kidney. After the removal, the surgical team takes measures to control any bleeding, places drains if necessary, and finally closes the incisions. It is important to note that if the nephrectomy is complicated by prior surgery on the same kidney, the additional code 50225 should be reported to reflect the complexity of the procedure.

1. Indications

The procedure of nephrectomy, including partial ureterectomy, is indicated for various conditions affecting the kidney and ureter. These may include:

  • Renal Tumors The presence of malignant or benign tumors in the kidney that necessitate removal to prevent further complications or metastasis.
  • Severe Kidney Damage Conditions such as chronic kidney disease or acute kidney injury that result in irreversible damage to the kidney, making nephrectomy necessary.
  • Ureteral Obstruction Blockages in the ureter that lead to hydronephrosis or other complications, requiring surgical intervention.
  • Kidney Stones Large or recurrent kidney stones that cannot be managed through less invasive methods and pose a risk of infection or kidney damage.

2. Procedure

The nephrectomy procedure involves several critical steps to ensure the safe and effective removal of the kidney and a portion of the ureter. The following outlines the procedural steps:

  • Step 1: Incision A wide flank incision is made, typically located just below the lower border of the ribs or near the 11th or 12th rib. This incision allows the surgeon to access the kidney effectively. If necessary, the 11th and/or 12th ribs may be resected to facilitate better surgical access.
  • Step 2: Exposure of the Kidney and Ureter Once the incision is made, the surgeon carefully exposes the kidney and the ureter. This step is crucial for visualizing the structures involved and preparing for the subsequent steps of the procedure.
  • Step 3: Isolation of Renal Vessels The renal artery and vein are isolated, which involves carefully dissecting around these blood vessels. They are then ligated and divided to prevent bleeding during the removal of the kidney.
  • Step 4: Dissection of the Kidney The kidney is meticulously dissected free from the surrounding tissues. This step requires precision to avoid damaging adjacent structures and to ensure a clean removal.
  • Step 5: Partial Ureterectomy A section of the ureter is removed. This involves first dissecting the affected portion of the ureter free from surrounding tissue, followed by dividing the ureter and excising the diseased section along with the kidney.
  • Step 6: Hemostasis and Drain Placement After the kidney and ureter have been removed, the surgical team takes measures to control any bleeding. Drains may be placed as needed to prevent fluid accumulation in the surgical site.
  • Step 7: Closure of Incisions Finally, the incisions are closed using appropriate suturing techniques to promote healing and minimize scarring.

3. Post-Procedure

Post-procedure care following a nephrectomy includes monitoring for any signs of complications such as bleeding or infection. Patients may require pain management and will be advised on activity restrictions during the recovery period. Follow-up appointments are essential to assess healing and kidney function. Additionally, if drains were placed, they will need to be monitored and removed as appropriate. The overall recovery time can vary based on the individual’s health status and the complexity of the surgery.

22 Increased procedural services: when the work required to provide a service is substantially greater than typically required, it may be identified by adding modifier 22 to the usual procedure code. documentation must support the substantial additional work and the reason for the additional work (ie, increased intensity, time, technical difficulty of procedure, severity of patient's condition, physical and mental effort required). note: this modifier should not be appended to an e/m service.
50 Bilateral procedure: unless otherwise identified in the listings, bilateral procedures that are performed at the same session, should be identified by adding modifier 50 to the appropriate 5 digit code. note: this modifier should not be appended to designated "add-on" codes (see appendix d).
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).
52 Reduced services: under certain circumstances a service or procedure is partially reduced or eliminated at the discretion of the physician or other qualified health care professional. under these circumstances the service provided can be identified by its usual procedure number and the addition of modifier 52, signifying that the service is reduced. this provides a means of reporting reduced services without disturbing the identification of the basic service. note: for hospital outpatient reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well-being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use).
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.
59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
62 Two surgeons: when 2 surgeons work together as primary surgeons performing distinct part(s) of a procedure, each surgeon should report his/her distinct operative work by adding modifier 62 to the procedure code and any associated add-on code(s) for that procedure as long as both surgeons continue to work together as primary surgeons. each surgeon should report the co-surgery once using the same procedure code. if additional procedure(s) (including add-on procedure(s) are performed during the same surgical session, separate code(s) may also be reported with modifier 62 added. note: if a co-surgeon acts as an assistant in the performance of additional procedure(s), other than those reported with the modifier 62, during the same surgical session, those services may be reported using separate procedure code(s) with modifier 80 or modifier 82 added, as appropriate.
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.)
79 Unrelated procedure or service by the same physician or other qualified health care professional during the postoperative period: the individual may need to indicate that the performance of a procedure or service during the postoperative period was unrelated to the original procedure. this circumstance may be reported by using modifier 79. (for repeat procedures on the same day, see modifier 76.)
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
82 Assistant surgeon (when qualified resident surgeon not available): the unavailability of a qualified resident surgeon is a prerequisite for use of modifier 82 appended to the usual procedure code number(s).
