Official Description

Laparoscopy, surgical; donor nephrectomy (including cold preservation), from living donor

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

A laparoscopic donor nephrectomy is a surgical procedure performed to remove a kidney from a living donor for transplantation purposes. This minimally invasive technique involves making small incisions in the abdomen, allowing for the use of a laparoscope, which is a thin tube equipped with a camera and light. The procedure includes the cold preservation of the donor kidney, which is essential for maintaining the organ's viability until it can be transplanted into the recipient. During the operation, the surgeon creates a pneumoperitoneum by insufflating the abdomen with air, which provides a working space to visualize and access the internal organs. The lateral line of Toldt is identified and incised to mobilize the peritoneum over the kidney, allowing for better visualization of the kidney and its surrounding structures. The colon is carefully mobilized to gain access to the kidney, and various ligaments and fascia are divided to expose the renal hilum, where the renal artery and vein are located. The procedure requires meticulous dissection to avoid damaging the vascular pedicle and to ensure the kidney remains viable for transplantation. Once the kidney is fully mobilized and detached from its attachments, it is placed in a preservation bag, and cold preservation solutions may be applied to maintain its function until it is delivered to the recipient surgical team.

1. Indications

The laparoscopic donor nephrectomy procedure is indicated for the following:

  • Living Donor Kidney Transplantation This procedure is performed to procure a kidney from a living donor for transplantation into a recipient with end-stage renal disease or other renal dysfunction.

2. Procedure

The laparoscopic donor nephrectomy involves several critical procedural steps:

  • Step 1: Preparation and Anesthesia The patient is positioned appropriately, and general anesthesia is administered to ensure comfort and immobility 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 laparoscopic instruments.
  • Step 3: Insertion of Trocars and Laparoscope Trocars are placed through the incisions, and a laparoscope is inserted through the umbilical port to visualize the surgical field.
  • Step 4: Mobilization of the Kidney The lateral line of Toldt is identified and incised, allowing the peritoneum over the kidney to be mobilized. The anterior surface of the kidney is then visualized.
  • Step 5: Colon Mobilization The colon is mobilized and rolled medially to provide better access to the kidney.
  • Step 6: Division of Ligaments The colorenal ligaments are divided, and Gerota's fascia is exposed to access the kidney and its surrounding structures.
  • Step 7: 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 8: Dissection of the Renal Hilum The lower pole of the kidney is partially mobilized, and the renal hilum is dissected free of surrounding structures to expose the renal vein and artery.
  • Step 9: Clipping and Dividing Veins The gonadal, lumbar, and adrenal veins are clipped and divided to facilitate the removal of the kidney.
  • Step 10: Dissection of the Renal Artery The renal artery is identified and dissected free of surrounding tissue, while lateral, posterior, and inferior kidney attachments are left intact to prevent torsion and vascular damage.
  • Step 11: Ureter Dissection The ureter is dissected free of surrounding tissue to the level of the iliac vessels and then divided.
  • Step 12: Final Mobilization of the Kidney The kidney is dissected free from the remaining lateral and inferior attachments, and the lower pole is elevated and dissected free of posterior attachments.
  • Step 13: Extension of Incision The periumbilical incision is extended while preserving the pneumoperitoneum and the integrity of the peritoneum.
  • Step 14: Division of the Vascular Pedicle The vascular pedicle containing the renal artery and vein is divided, completing the dissection of the kidney.
  • Step 15: Kidney Retrieval The laparoscope is removed from the umbilical port, and a bag is inserted through the umbilical port to contain the kidney. The peritoneum is opened, and the kidney is delivered.
  • Step 16: Cold Preservation The kidney may be perfused with cold preservation solution and/or placed on ice before being delivered to the recipient surgical team.

3. Post-Procedure

After the laparoscopic donor nephrectomy, the donor is monitored for any complications and provided with post-operative care. Recovery typically involves managing pain and ensuring proper healing of the incisions. The donor may be advised on activity restrictions and follow-up appointments to monitor kidney function and overall health. The kidney, once preserved, is promptly delivered to the recipient surgical team for transplantation.

Q3 Live kidney donor surgery and related services
LT Left side (used to identify procedures performed on the left side of the body)
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).
AS Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery
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.
GC This service has been performed in part by a resident under the direction of a teaching physician
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.
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
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).
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.
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.
