CPT 38571: Laparoscopic Bilateral Pelvic Lymphadenectomy

CPT code 38571 represents a laparoscopic bilateral pelvic lymphadenectomy: a minimally invasive surgical procedure to visualize and remove pelvic lymph nodes on both sides of the pelvis. Nationally, this code is used in oncologic surgical management to stage and reduce the risk of regional nodal metastasis for pelvic malignancies. It is clinically significant because lymph node status guides adjuvant therapy decisions and prognostic assessment.

Payers included in the analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context, typical settings of service, common billing modifiers, and payer coverage patterns. The publication outlines benchmark metrics where available, summarizes relevant policy and coding considerations affecting reimbursement and claim adjudication, and highlights operational implications for surgical services and revenue cycle teams.

The content is designed for a national audience of clinicians, coding professionals, and healthcare administrators seeking clarity on clinical intent, billing practice, and payer coverage themes for CPT code 38571. Data not available in the input is noted where applicable.

Billing Code Overview

CPT code 38571 describes a laparoscopic bilateral pelvic lymphadenectomy. The procedure involves making small incisions in the abdomen, inserting a camera (laparoscope) to visualize the pelvic lymph nodes, and excising all lymph nodes on both sides of the pelvis to remove diseased nodes and reduce the risk of cancer spread.

Service type: Surgical procedure — laparoscopic pelvic lymph node dissection
Typical site of service: Inpatient or outpatient surgical setting; most commonly performed in an operating room with laparoscopic equipment

Clinical & Coding Specifications

Clinical Context

A 58-year-old woman with high-grade endometrial carcinoma is referred for surgical staging. Preoperative imaging shows a uterine mass without clear distant metastasis but with possible pelvic nodal involvement. The gynecologic oncology team schedules a minimally invasive bilateral pelvic lymphadenectomy via laparoscopy to remove and pathologically evaluate pelvic lymph nodes for staging and to guide adjuvant therapy.

The clinical workflow: preoperative evaluation in the clinic with review of pathology and imaging, informed consent documenting indications and alternatives, general anesthesia in an operating room, placement of laparoscopic ports, inspection of the abdomen and pelvis with a camera, dissection and removal of all pelvic lymphatic tissue bilaterally, hemostasis, specimen labeling and send to pathology, closure of port sites, postoperative recovery unit monitoring, and discharge instructions with pathology follow-up and oncology coordination.

Coding Specifications

Modifier	Description	When to Use
`50`	Bilateral procedure	Use when procedure is performed on both pelvic sides; often inherent in bilateral pelvic lymphadenectomy but some payors require modifier for bilateral claims.
`51`	Multiple procedures	When additional unrelated CPT-coded procedures are performed in the same operative session (billing primary procedure plus reduced payment for secondary).
`52`	Reduced services	When the service is partially reduced or not completed as described.
`53`	Discontinued procedure	When the procedure is started but discontinued due to extenuating circumstances.
`58`	Staged or related procedure or service by the same physician during the postoperative period	When the surgery is planned as the initial of a staged treatment performed during the global period.
`59`	Distinct procedural service	When an unrelated procedure or a separately identifiable service is performed at a separate anatomical site or session.
`62`	Two surgeons	When two surgeons work together as primary surgeons performing distinct parts of a single procedure.
`76` is not in list; omitted
`78`	Unplanned return to the operating room for a related procedure during the postoperative period	When the patient returns to the OR emergently for a complication related to the initial lymphadenectomy.
`79`	Unrelated procedure or service by the same physician during the postoperative period	Use when an unrelated procedure is performed during the global period.
`LT`	Left side	When reporting lateralized services performed on the left pelvic side; used if payor requires laterality rather than `50`.
`RT`	Right side	When reporting lateralized services performed on the right pelvic side; used if payor requires laterality rather than `50`.
`22`	Increased procedural services	When work required to perform the procedure is substantially greater than typically required (document rationale).
`26`	Professional component	If only the professional component is billed separate from the technical component (rare for an operative procedure).

Taxonomy Code	Specialty	Notes
`207V00000X`	Obstetrics & Gynecology	Gynecologic oncologists commonly perform laparoscopic pelvic lymphadenectomy.
`2080P0222X`	Surgery	General surgeons may perform pelvic lymphadenectomy in non-gynecologic pelvic malignancies.
`2085R0202X`	Surgical Oncology	Surgical oncologists perform nodal dissections as part of cancer staging and treatment.
`207L00000X`	Gynecologic Oncology	Subspecialists specifically trained in oncologic gynecologic surgery perform this procedure.
