Common Language Description

The procedure described by CPT® Code 38573 involves a laparoscopic surgical approach to perform a bilateral total pelvic lymphadenectomy, which is the removal of lymph nodes from both sides of the pelvis. This procedure may also include sampling of the para-aortic lymph nodes, which are located near the aorta, as well as various other interventions such as peritoneal washings, peritoneal biopsies, omentectomy, and diaphragmatic washings. The laparoscopic technique is minimally invasive, utilizing small incisions to access the abdominal cavity, which allows for reduced recovery time and less postoperative pain compared to traditional open surgery. The surgeon begins by creating a small incision below the umbilicus to insert a trocar, through which a laparoscope is introduced to visualize the internal structures. Additional incisions are made to insert surgical instruments necessary for the procedure. The surgeon carefully inspects the peritoneal cavity for signs of metastatic disease, ensuring to preserve critical anatomical structures such as the genitofemoral nerve and psoas muscle. The fatty tissue surrounding the common iliac vessels is meticulously stripped to access and excise the lymph nodes bilaterally. The excised lymph nodes, along with surrounding tissue, are placed in an endobag for removal through a larger incision. The procedure may also involve taking biopsies of the para-aortic lymph nodes, which are then sent for frozen section analysis. If necessary, involved para-aortic lymph nodes are excised and removed in a similar manner. This comprehensive approach allows for thorough evaluation and treatment of potential malignancies in the pelvic and abdominal regions.

1. Indications

The procedure described by CPT® Code 38573 is indicated for various clinical scenarios where there is a need for comprehensive evaluation and treatment of potential malignancies in the pelvic and abdominal regions. The specific indications include:

  • Pelvic malignancies - This procedure is often performed in patients with known or suspected cancers of the reproductive organs, such as ovarian, uterine, or cervical cancer, where lymph node involvement is a concern.
  • Metastatic disease assessment - It is indicated for patients requiring assessment for metastatic spread of cancer, particularly when there is a need to evaluate lymphatic drainage pathways.
  • Staging of cancer - The procedure aids in the staging of pelvic cancers by providing critical information regarding lymph node involvement, which is essential for determining the appropriate treatment plan.
  • Diagnostic purposes - It may also be indicated for diagnostic purposes when imaging studies suggest possible lymphadenopathy or other abnormalities in the pelvic region.

2. Procedure

The procedure involves several key steps, each critical to the successful completion of the laparoscopic bilateral total pelvic lymphadenectomy and associated interventions:

  • Step 1: Establishing access - The surgeon begins by making a small incision just below the umbilicus to insert a trocar. This trocar allows for the establishment of pneumoperitoneum, which is the inflation of the abdominal cavity with gas to create a working space for the procedure.
  • Step 2: Insertion of laparoscope - A laparoscope, which is a specialized camera, is introduced through the umbilical port. This instrument provides visualization of the internal structures, allowing the surgeon to navigate the abdominal cavity effectively.
  • Step 3: Additional incisions and instrument placement - The surgeon makes additional portal incisions to insert more trocars, which facilitate the introduction of various surgical instruments needed for the procedure.
  • Step 4: Exploration of the peritoneal cavity - The peritoneal cavity is thoroughly inspected, and the abdomen and pelvis are explored for any evidence of metastatic disease. This step is crucial for assessing the extent of disease and planning further interventions.
  • Step 5: Lymph node dissection - Care is taken to preserve critical structures such as the genitofemoral nerve and psoas muscle while stripping fatty tissue from the mid-portion of both common iliac vessels. The surgeon then excises the iliac, hypogastric, and obturator lymph nodes bilaterally.
  • Step 6: Removal of excised tissue - The excised lymph nodes and surrounding tissue are placed in an endobag, which is then removed through an enlarged portal incision to minimize contamination of the surgical field.
  • Step 7: Para-aortic lymph node sampling - The para-aortic lymph nodes are exposed, and biopsies are taken for frozen section analysis. If any nodes are found to be involved, they are excised and also removed in an endobag.
  • Step 8: Additional procedures - The procedure may include peritoneal washings, peritoneal biopsies, omentectomy, and diaphragmatic washings, including any necessary biopsies of the diaphragm or serosal surfaces, to ensure comprehensive evaluation and treatment.

3. Post-Procedure

After the completion of the procedure, patients are typically monitored for any immediate postoperative complications. Expected recovery includes managing pain at the incision sites and monitoring for signs of infection. Patients may be advised on activity restrictions and follow-up appointments for pathology results from the biopsies taken during the procedure. The overall recovery time can vary based on individual patient factors and the extent of the surgery performed, but laparoscopic techniques generally allow for quicker recovery compared to open surgical approaches. Patients should be informed about potential signs of complications, such as excessive bleeding or unusual pain, and instructed to seek medical attention if these occur.

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).
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.
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.)
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).
AS Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery
CR Catastrophe/disaster related
GC This service has been performed in part by a resident under the direction of a teaching physician
LT Left side (used to identify procedures performed on the left side of the body)
