Summary & Overview
CPT 38570: Laparoscopic Retroperitoneal Lymph Node Sampling
CPT code 38570 designates a laparoscopic retroperitoneal lymph node sampling or biopsy procedure used to stage cancer in the retroperitoneum and nearby structures. Nationally, this code matters because it captures a diagnostic surgical staging service that influences oncology care decisions, subsequent treatment planning, and claims processing for minimally invasive oncologic procedures. Payers use this code to adjudicate surgical claims, determine facility and surgeon payment, and evaluate utilization of laparoscopic staging versus open approaches.
Key payers included in this analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical context for the procedure, typical sites of service, and which payers commonly cover this type of surgical staging. The publication also summarizes common modifiers associated with surgical procedures (listed separately), discusses typical claim considerations for laparoscopic surgical staging, and outlines benchmarking and policy topics relevant to authorization, facility charges, and coding specificity.
The content helps clinicians, coding staff, and policy analysts understand the clinical role of CPT code 38570, how it is used in claims, and what operational and payer issues commonly arise around laparoscopic retroperitoneal lymph node sampling. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 38570 describes a minimally invasive surgical procedure in which the provider makes small incisions to insert a laparoscope (camera) and specialized instruments to sample one or more lymph nodes in the retroperitoneum. The procedure is performed to stage cancer in the retroperitoneal region and adjacent areas by obtaining tissue for histologic evaluation.
-
Service type: Laparoscopic retroperitoneal lymph node sampling/biopsy (diagnostic surgical staging)
-
Typical site of service: Hospital operating room or ambulatory surgical center, with possible intraoperative transfer to a higher acuity setting depending on findings or patient needs.
Clinical & Coding Specifications
Clinical Context
A 62-year-old man with newly diagnosed testicular germ cell tumor undergoes staging evaluation. Imaging with CT scan shows enlarged retroperitoneal lymph nodes suspicious for metastatic disease. The surgical oncology team schedules a minimally invasive retroperitoneal lymph node sampling via laparoscopy to obtain tissue for histopathology and staging prior to definitive therapy.
The patient presents to an outpatient ambulatory surgery center after preoperative assessment. Under general anesthesia, the surgeon creates small abdominal trocar sites, inserts a laparoscope for visualization of the retroperitoneum, and uses laparoscopic instruments to sample one or more suspicious lymph nodes. Specimens are sent for frozen section and permanent pathology. The perioperative documentation includes indication, informed consent, operative findings, nodes sampled, estimated blood loss, drains placed (if any), and disposition to recovery. Postoperative orders address pain control, DVT prophylaxis, and follow-up for pathology results to finalize oncologic staging and treatment planning.
