Official Description

Prostatectomy, retropubic radical, with or without nerve sparing; with bilateral pelvic lymphadenectomy, including external iliac, hypogastric, and obturator nodes

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 55845 refers to a retropubic radical prostatectomy, which is a surgical intervention aimed at removing the prostate gland along with surrounding tissues and lymph nodes. This operation is typically indicated for patients diagnosed with prostate cancer. The term "retropubic" indicates that the incision is made in the lower abdomen, specifically in the midline, allowing access to the prostate without entering the peritoneal cavity. The procedure may be performed with or without nerve-sparing techniques, which aim to preserve the nerves responsible for erectile function. Additionally, this code includes a bilateral pelvic lymphadenectomy, which involves the removal of lymph nodes from both sides of the pelvis, specifically targeting the external iliac, hypogastric, and obturator nodes. This is crucial for staging the cancer and determining the extent of its spread. The detailed steps of the procedure ensure that the malignancy is addressed effectively while minimizing damage to surrounding structures, thereby enhancing the potential for recovery and quality of life post-surgery.

1. Indications

The retropubic radical prostatectomy with bilateral pelvic lymphadenectomy, as described by CPT® Code 55845, is indicated for the following conditions:

  • Prostate Cancer: This procedure is primarily performed for patients diagnosed with localized prostate cancer, particularly when there is a need to assess the spread of the disease to nearby lymph nodes.
  • Suspicion of Lymph Node Involvement: Indications may include cases where imaging or clinical findings suggest potential involvement of the pelvic lymph nodes, necessitating their removal for pathological evaluation.

2. Procedure

The procedure involves several critical steps to ensure the effective removal of the prostate and associated lymph nodes:

  • Step 1: An incision is made in the midline of the lower abdomen to access the pelvic region. If lymphadenectomy is indicated, this step is performed first to evaluate the lymph nodes.
  • Step 2: The pelvic lymph nodes on one side are explored without opening the peritoneum. Care is taken to preserve the genitofemoral nerve and the psoas muscle while stripping fatty tissue from the common iliac vessel and along the external iliac vessel.
  • Step 3: Biopsies of the iliac, hypogastric, and obturator nodes are taken and sent for pathology evaluation. If malignancy is detected, these nodes are excised.
  • Step 4: The procedure is mirrored on the opposite side if necessary, ensuring thorough evaluation and removal of lymphatic tissue.
  • Step 5: The prostate is accessed by removing retropubic fat. The superficial branch of the dorsal venous complex is isolated and cauterized to minimize bleeding.
  • Step 6: The prostatic fascia and dorsal venous complex are exposed, ligated, and divided to facilitate access to the prostate.
  • Step 7: The prostatic fascia is incised, and the neurovascular bundles on either side of the prostate are identified, mobilized posteriorly, and protected. If malignancy has spread to surrounding tissues, these structures may be excised.
  • Step 8: Using finger dissection, the Denonvilliers fascia covering the posterior prostate and anterior rectum is separated, continuing to the prostato-apical junction bilaterally.
  • Step 9: The lateral prostatic fascia on one side is incised, exposing and dividing the membranous urethra.
  • Step 10: The prostate is completely mobilized while ligating vascular pedicles close to the prostate, ensuring minimal blood loss.
  • Step 11: The anterior layer of Denonvilliers fascia is divided, and the ampullae of the vas deferens are located, dissected off the medial aspect of the seminal vesicles, and divided.
  • Step 12: The seminal vesicles are dissected free from the bladder base and posterior aspect of the bladder, allowing for complete removal of the prostate.
  • Step 13: The prostate is removed en bloc, ensuring that all cancerous tissue is excised.
  • Step 14: The bladder neck is repaired as necessary, and a sound is placed in the urethra to facilitate anastomosis.
  • Step 15: The bladder is anastomosed to the urethra, and the surgical wound is closed in layers to promote healing.

3. Post-Procedure

Post-procedure care following a retropubic radical prostatectomy with bilateral pelvic lymphadenectomy includes monitoring for complications such as bleeding, infection, and urinary retention. Patients may require a catheter for urinary drainage for a period following surgery. Recovery typically involves pain management and gradual resumption of normal activities, with specific instructions provided by the surgical team. Follow-up appointments are essential to monitor recovery and assess for any signs of cancer recurrence or complications related to the surgery.

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).
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.
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.
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).
