Summary & Overview
CPT 38780: Retroperitoneal and Abdominal Lymphadenectomy
CPT code 38780 represents extensive surgical excision of lymph nodes from the retroperitoneal area and throughout the abdomen, including pelvic, aortic, and renal nodal dissection for cancer arising in the lower abdomen. This complex oncologic procedure is significant nationally because it reflects advanced surgical management for staging and treatment of abdominal malignancies and can drive substantial resource use, perioperative risk, and postoperative care needs.
Key payers discussed include 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 the service type. The publication outlines what to expect in payer coverage discussions, common billing modifiers relevant to procedural reporting, and benchmarks related to utilization and reimbursement where available. It also summarizes policy and coding considerations that influence claims processing and payment adjudication for major lymphadenectomy procedures.
The article provides actionable reference material for revenue cycle, coding, and clinical teams seeking clarity on coding designation, site-of-service implications, and areas where payer policy updates commonly arise. Data not available in the input will be noted where applicable.
Billing Code Overview
CPT code 38780 describes an extensive surgical excision of retroperitoneal and abdominal lymph nodes, including pelvic, aortic, and renal nodal dissection. The procedure involves removal of pelvic, aortic, renal, and other lymph nodes in the lower abdomen for treatment of cancer originating in the lower abdomen.
Service Type: Extensive abdominal and retroperitoneal lymphadenectomy
Typical Site of Service: Inpatient or outpatient surgical setting, most commonly performed in an operating room within a hospital or ambulatory surgery center
Clinical & Coding Specifications
Clinical Context
A typical patient is a 54-year-old individual diagnosed with a lower abdominal malignancy (for example, testicular germ cell tumor or advanced ovarian/cervical carcinoma) who requires an extensive retroperitoneal and pelvic lymphadenectomy for disease control and staging. The patient presents with radiographic evidence of enlarged pelvic, aortic, and renal lymph nodes on CT or PET-CT and meets oncologic criteria for surgical lymph node removal. Preoperative workflow includes multidisciplinary tumor board review, informed consent specific to extensive lymphadenectomy risks (bleeding, adjacent organ injury, lymphatic leak), pre-op labs and crossmatch as indicated, and anesthesia evaluation. Intraoperative workflow involves a general/oncologic surgeon performing an open or extended retroperitoneal approach to excise pelvic, aortic, renal, and lower abdominal lymph node basins. Specimens are labeled by nodal station and sent to surgical pathology. Postoperative care includes monitoring for hemorrhage, urine output (renal node dissection proximity), early ambulation, DVT prophylaxis, and specific management for chylous ascites if lymphatic channels are disrupted. Documentation must capture extent of dissection, laterality, nodal stations removed, operative time, blood loss, complications, and whether additional procedures were performed concurrently (for example tumor resection or bowel resection). Typical site of service is an inpatient hospital operating room; ambulatory surgery center performance is uncommon for this extensive procedure.
