Official Description

Laparoscopy, surgical prostatectomy, retropubic radical, including nerve sparing, includes robotic assistance, when performed

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 55866 refers to a laparoscopic surgical procedure known as retropubic radical prostatectomy, which is performed to remove the prostate gland and some surrounding tissue. This procedure can be conducted using either a transperitoneal or extraperitoneal approach. In the transperitoneal method, a small incision is made near the umbilicus to create an entry point for the laparoscope, which is a specialized instrument used to visualize the surgical area. Pneumoperitoneum, or the introduction of gas into the abdominal cavity, is established to create space for the surgeon to work. The laparoscope is then inserted, allowing for inspection of the abdominal cavity. Additional incisions are made to accommodate surgical instruments necessary for the procedure. The surgeon carefully dissects the tissue between the rectum and bladder to access the prostate, ensuring that critical structures, such as nerves, are preserved when possible, which is referred to as nerve-sparing surgery. The procedure involves meticulous steps, including the ligation of the dorsal vein, incision of the bladder neck, and dissection of the lateral pedicles, ultimately leading to the removal of the prostate and seminal vesicles. In cases where the extraperitoneal approach is utilized, the procedure begins with a small incision to insufflate the preperitoneum, allowing for the development of the retropubic space through blunt dissection. Robotic assistance may be employed during the procedure to enhance precision and control. The laparoscopic prostatectomy is a minimally invasive technique that aims to reduce recovery time and postoperative pain while achieving the same oncological outcomes as traditional open surgery.

1. Indications

The retropubic radical prostatectomy, as described by CPT® Code 55866, is indicated for the surgical treatment of prostate cancer. This procedure is typically performed on patients diagnosed with localized prostate cancer who are candidates for surgical intervention. The indications for this procedure may include:

  • Localized Prostate Cancer Patients with prostate cancer that has not spread beyond the prostate gland and is confined to the organ.
  • Elevated Prostate-Specific Antigen (PSA) Levels Individuals presenting with elevated PSA levels that suggest the presence of prostate cancer.
  • Abnormal Digital Rectal Exam (DRE) Patients who have abnormal findings during a digital rectal examination, indicating potential prostate malignancy.

2. Procedure

The procedure for a retropubic radical prostatectomy using CPT® Code 55866 involves several detailed steps, which can vary slightly depending on whether a transperitoneal or extraperitoneal approach is utilized. The following outlines the procedural steps:

  • Step 1: Initial Incision and Pneumoperitoneum For the transperitoneal approach, a periumbilical incision is made to create the initial laparoscopic port. Pneumoperitoneum is established by introducing gas into the abdominal cavity, allowing for better visualization and access to the surgical area.
  • Step 2: Insertion of Laparoscope A conventional or robotic laparoscope is inserted through the infraumbilical port into the peritoneum, enabling the surgeon to inspect the abdominal cavity for any abnormalities.
  • Step 3: Additional Port Incisions Additional incisions are made to introduce surgical instruments necessary for the procedure, facilitating the various surgical tasks that will follow.
  • Step 4: Dissection of Seminal Vesicles An incision is made in the peritoneal fold between the rectum and bladder, allowing for the dissection and retraction of the seminal vesicles to expose the Denonvilliers aponeurosis.
  • Step 5: Incision of Aponeurosis The Denonvilliers aponeurosis is incised, and dissection continues to the rectourethral muscle, which separates the prostate from the rectum.
  • Step 6: Entry into Retzius Space The peritoneum is incised, allowing access to the space of Retzius, which causes the bladder to fall posteriorly, providing better access to the prostate.
  • Step 7: Incision of Endopelvic Fascia The endopelvic fascia is incised, and the levator muscle is pushed aside to facilitate the resection of the prostate gland.
  • Step 8: Ligation and Resection The dorsal vein is ligated, and the bladder neck is incised. The lateral pedicles are dissected, and the urethra is transected, allowing for the removal of the prostate along with the seminal vesicles.
  • Step 9: Urethra Re-anastomosis After the prostate is removed, the urethra is re-anastomosed to the bladder neck to restore urinary continuity.
  • Step 10: Drain Placement and Closure A drain is placed to facilitate fluid drainage, after which the laparoscope and surgical instruments are removed, and the portal incisions are closed.
  • Step 11: Extraperitoneal Approach If the extraperitoneal approach is used, a small incision is made, the preperitoneum is insufflated, and the space of Retzius is developed using blunt dissection until the pubic symphysis is reached. The retropubic space is further developed by placing a port in the midline above the symphysis and using extraperitoneal robotic instruments through additional right and left ports, continuing with the steps as described above.

3. Post-Procedure

Post-procedure care following a retropubic radical prostatectomy includes monitoring for complications such as bleeding, infection, and urinary retention. Patients are typically advised to rest and gradually increase their activity levels. A drain may remain in place for a short period to prevent fluid accumulation. Follow-up appointments are essential to assess recovery, manage any postoperative symptoms, and monitor PSA levels to ensure the effectiveness of the surgery. Patients may also receive guidance on pelvic floor exercises to aid in recovery and improve urinary function.

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.
77 Repeat procedure by another physician or other qualified health care professional: it may be necessary to indicate that a basic procedure or service was repeated by another physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 77 to the repeated procedure or service. note: this modifier should not be appended to an e/m service.
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.
