Official Description

Prostatectomy, retropubic radical, with or without nerve sparing; with lymph node biopsy(s) (limited pelvic lymphadenectomy)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 55842 refers to a retropubic radical prostatectomy, which is a surgical intervention aimed at the removal of the prostate gland along with surrounding tissues. This procedure may be performed with or without nerve-sparing techniques, which are designed to preserve the nerves that control erectile function. The surgery involves an incision in the midline of the lower abdomen, allowing access to the prostate and surrounding structures. A key component of this procedure is the lymph node biopsy, which may involve a limited pelvic lymphadenectomy, where specific pelvic lymph nodes are examined for the presence of malignancy. The approach is meticulous, ensuring that critical anatomical structures, such as the genitofemoral nerve and psoas muscle, are preserved during the dissection. The procedure is comprehensive, addressing both the prostate and any potentially affected lymph nodes, thereby providing essential information regarding the extent of cancer spread and guiding further treatment decisions.

1. Indications

The retropubic radical prostatectomy with lymph node biopsy, as described by CPT® Code 55842, is indicated for patients diagnosed with prostate cancer. The procedure is typically performed when there is a need to remove the prostate gland due to malignancy, particularly when there is a concern for the spread of cancer to nearby lymph nodes. The following conditions may warrant this surgical intervention:

  • Prostate Cancer Diagnosis Patients with confirmed prostate cancer who require surgical intervention for treatment.
  • Suspicion of Lymph Node Involvement Cases where there is a clinical suspicion or imaging evidence suggesting that cancer may have spread to the pelvic lymph nodes.
  • Need for Staging Situations where lymph node biopsy is necessary to determine the extent of cancer spread and to guide further treatment options.

2. Procedure

The procedure for CPT® Code 55842 involves several critical steps to ensure the effective removal of the prostate and assessment of lymph nodes. The following procedural steps are performed:

  • Step 1: Incision and Lymphadenectomy The lower abdomen is incised in the midline. If a lymphadenectomy is indicated, this is performed first, allowing for exploration of the pelvic lymph nodes on one side without opening the peritoneum. Care is taken to preserve the genitofemoral nerve and psoas muscle while stripping fatty tissue from the common iliac and external iliac vessels.
  • Step 2: Lymph Node Biopsy The iliac, hypogastric, and obturator lymph nodes are biopsied and sent for pathology evaluation. If malignancy is detected in these nodes, they are excised. This step may be repeated on the opposite side if necessary.
  • Step 3: Prostate Access The prostate is accessed by removing retropubic fat. The superficial branch of the dorsal venous complex is isolated and cauterized to minimize bleeding. The prostatic fascia and dorsal venous complex are then exposed, ligated, and divided.
  • Step 4: Neurovascular Bundle Management The neurovascular bundles on either side of the prostate are identified, mobilized posteriorly, and protected. If malignancy has spread to surrounding tissues, the neurovascular complex may be excised instead.
  • Step 5: Dissection of Denonvilliers Fascia Finger dissection is used to separate the Denonvilliers fascia covering the posterior prostate and anterior rectum, continuing to the prostato-apical junction bilaterally.
  • Step 6: Urethra Exposure and Prostate Mobilization The lateral prostatic fascia on one side is incised, exposing and dividing the membranous urethra. The prostate is then completely mobilized while ligating vascular pedicles close to the prostate.
  • Step 7: Seminal Vesicle Dissection 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. The seminal vesicles are then dissected free from the bladder base and posterior bladder.
  • Step 8: Prostate Removal The prostate is removed en bloc, ensuring it is free from all surrounding tissue. The bladder neck is repaired as needed.
  • Step 9: Anastomosis and Closure A sound is placed in the urethra, and the bladder is anastomosed to the urethra. Finally, the surgical wound is closed in layers to promote healing.

3. Post-Procedure

Post-procedure care following a retropubic radical prostatectomy with lymph node biopsy 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. Follow-up appointments are essential to assess healing and discuss pathology results from the lymph node biopsies, which will inform further treatment options if necessary. Patients are advised to adhere to postoperative instructions regarding activity restrictions and signs of complications to ensure optimal recovery.

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.
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).
54 Surgical care only: when 1 physician or other qualified health care professional performs a surgical procedure and another provides preoperative and/or postoperative management, surgical services may be identified by adding modifier 54 to the usual procedure number.
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).
