38564 Retroperitoneal Lymph Node Excision CPT Reimbursement

CPT code 38564 denotes surgical excision of retroperitoneal lymph nodes near the aorta or spleen for cancer staging. Nationally, this procedure is a key component of oncologic staging pathways for malignancies that may spread to the retroperitoneum, influencing treatment planning and prognosis. Utilization and reimbursement for this code affect surgical oncology workflows, hospital resource allocation, and downstream therapy decisions.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context for the procedure, typical sites of service, and the operational importance of accurate coding. The publication presents benchmarks on utilization and payment where available, outlines common modifier usage and billing considerations, and summarizes relevant policy updates that affect coverage and authorization processes. Clinical implications for staging accuracy and care coordination are also discussed.

This summary is intended for national audiences including hospital coding teams, surgical oncologists, revenue cycle managers, and policy analysts seeking clear guidance on the role of CPT code 38564 in cancer staging workflows and payer interactions. Data not available in the input is noted where applicable.

Billing Code Overview

CPT code 38564 describes the surgical excision of retroperitoneal lymph nodes located behind and outside the peritoneum near the aorta or spleen for staging of cancer in these areas. This procedure involves removal of lymphatic tissue in the retroperitoneal space to assess spread of malignancy and determine pathologic stage.

Service type: Surgical lymphadenectomy for oncologic staging
Typical site of service: Hospital operating room or ambulatory surgical center for procedures requiring general anesthesia and operative exposure of the retroperitoneal space

Clinical Context

A 58-year-old patient with a recent diagnosis of testicular germ cell tumor presents for surgical staging. Imaging (CT abdomen/pelvis) demonstrates enlarged para-aortic and interaortocaval lymph nodes suspicious for metastatic disease. The multidisciplinary tumor board recommends a retroperitoneal lymphadenectomy to obtain tissue for pathologic staging and therapeutic removal of bulky nodal disease.

The typical clinical workflow: preoperative evaluation with oncologic surgeon and anesthesia, informed consent for retroperitoneal lymph node dissection, pre-op labs and imaging review, general anesthesia with possible epidural for postoperative analgesia, open or minimally invasive retroperitoneal approach to excise lymph nodes posterior to the peritoneum near the aorta and spleen, specimen labeling and send to pathology, hemostasis and closure, post-anesthesia recovery and inpatient postoperative monitoring for fluid balance, bleeding, and ileus. Pathology staging results guide adjuvant therapy decisions by medical oncology.
