Official Description

Laparoscopy, surgical; radical nephrectomy (includes removal of Gerota's fascia and surrounding fatty tissue, removal of regional lymph nodes, and adrenalectomy)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 50545 refers to a laparoscopic radical nephrectomy, which is a surgical operation aimed at removing a kidney along with its surrounding structures. This includes the excision of Gerota's fascia, which is the connective tissue surrounding the kidney, as well as the surrounding fatty tissue, regional lymph nodes, and, if necessary, the adrenal gland. The laparoscopic approach involves making small incisions in the abdomen, through which specialized instruments and a camera (laparoscope) are inserted. This minimally invasive technique allows for reduced recovery time and less postoperative pain compared to traditional open surgery. The procedure is performed under general anesthesia and requires careful dissection and identification of various anatomical structures to ensure complete removal of the kidney and associated tissues while minimizing damage to surrounding organs. The use of pneumoperitoneum, achieved by insufflating the abdomen with air, creates a working space for the surgeon to operate effectively. Overall, this procedure is indicated for conditions such as renal tumors, severe kidney disease, or other pathologies affecting the kidney that necessitate its removal.

1. Indications

Radical nephrectomy via laparoscopic approach is indicated for several specific conditions affecting the kidney. These include:

  • Renal Tumors The presence of malignant tumors in the kidney that require complete removal to prevent metastasis and further complications.
  • Severe Kidney Disease Conditions such as chronic kidney disease or end-stage renal disease where the kidney is no longer functioning adequately.
  • Kidney Trauma Significant injury to the kidney that cannot be repaired and necessitates removal.
  • Congenital Anomalies Structural abnormalities of the kidney that impair its function or pose a risk of complications.

2. Procedure

The laparoscopic radical nephrectomy procedure involves several detailed steps to ensure the safe and effective removal of the kidney and associated structures. The steps include:

  • Step 1: Preparation and Anesthesia The patient is positioned appropriately on the operating table, and general anesthesia is administered to ensure the patient is unconscious and pain-free during the procedure.
  • Step 2: Creation of Pneumoperitoneum Small incisions are made in the abdomen, and the abdomen is insufflated with air to create a working space for the surgical instruments.
  • Step 3: Insertion of Trocars and Laparoscope Trocars, which are specialized instruments, are placed through the incisions, and a laparoscope is inserted through the umbilical port to provide visualization of the surgical field.
  • Step 4: Mobilization of the Kidney The lateral line of Toldt is identified and incised, allowing for mobilization of the peritoneum over the kidney. The anterior surface of the kidney is visualized, and the colon is mobilized medially to gain access.
  • Step 5: Dissection of Gerota's Fascia The colorenal ligaments are divided, exposing Gerota's fascia. The fascia is dissected free from surrounding structures, and regional lymph nodes are excised.
  • Step 6: Identification of Vascular Structures The ureter and surrounding vascular structures are identified and retracted to expose the lower pole of the kidney and the renal hilum.
  • Step 7: Division of Renal Vessels The renal artery and vein are identified, divided, and ligated to ensure complete removal of the kidney.
  • Step 8: Adrenalectomy Dissection continues medially along the inferior vena cava to the adrenal vein, which is divided and ligated. The adrenal gland is then dissected free from surrounding tissue.
  • Step 9: Removal of the Kidney The kidney is dissected free from any remaining lateral and superior attachments, and the ureter is divided.
  • Step 10: Specimen Retrieval The laparoscope is removed from the umbilical port and inserted into the lateral port. A bag is then inserted through the umbilical port, and the kidney, Gerota's fascia, surrounding fatty tissue, regional lymph nodes, and the adrenal gland are placed in the bag for removal.
  • Step 11: Closure The umbilical incision is extended to facilitate the removal of the bag containing the kidney and surrounding structures. The surgical site is inspected for any bleeding, which is controlled, and the surgical instruments are removed before closing the incisions.

3. Post-Procedure

After the laparoscopic radical nephrectomy, the patient is monitored in a recovery area until the effects of anesthesia wear off. Post-procedure care includes managing pain with appropriate medications, monitoring for any signs of complications such as bleeding or infection, and ensuring the patient is stable before discharge. Patients are typically advised to follow up with their healthcare provider for further evaluation and to discuss any additional treatments or interventions that may be necessary. Recovery time may vary, but many patients can return to normal activities within a few weeks, depending on their overall health and the extent of the surgery.

80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
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).
53 Discontinued procedure: under certain circumstances, the physician or other qualified health care professional may elect to terminate a surgical or diagnostic procedure. due to extenuating circumstances or those that threaten the well being of the patient, it may be necessary to indicate that a surgical or diagnostic procedure was started but discontinued. this circumstance may be reported by adding modifier 53 to the code reported by the individual for the discontinued procedure. note: this modifier is not used to report the elective cancellation of a procedure prior to the patient's anesthesia induction and/or surgical preparation in the operating suite. for outpatient hospital/ambulatory surgery center (asc) 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.)
81 Minimum assistant surgeon: minimum surgical assistant services are identified by adding modifier 81 to the usual procedure number.
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).
