Summary & Overview
CPT 47370: Laparoscopic Radiofrequency Ablation of Liver Tumor
CPT code 47370 represents laparoscopic radiofrequency ablation of one or more liver tumors, a minimally invasive surgical technique used to destroy focal hepatic lesions. Nationally, this code captures care delivered in operating rooms and ambulatory surgery centers where practitioners use laparoscopic access and radiofrequency energy to treat primary or metastatic liver tumors. The approach is important for patients who are not candidates for open resection or who require targeted tumor control.
Key payers included in the analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical context for CPT code 47370, typical sites of service, and how the procedure is categorized for billing. The publication outlines common modifiers and associated coding considerations (Data not available in the input), and identifies related administrative elements that affect claims processing (Data not available in the input).
This summary equips revenue cycle leaders, clinicians, and policy analysts with baseline knowledge about what CPT code 47370 denotes, where the service is typically provided, and which major payers are relevant for coverage and billing discussions. The content also previews operational implications for facility and practitioner billing workflows and points readers to sections with benchmarking and policy update coverage.
Billing Code Overview
CPT code 47370 describes laparoscopic radiofrequency ablation of one or more liver tumors. The procedure uses radiofrequency energy delivered via a laparoscope to destroy malignant or benign tumors within the liver.
Service type: Minimally invasive operative procedure
Typical site of service: Hospital operating room or ambulatory surgery center, performed under general anesthesia via laparoscopy
Clinical & Coding Specifications
Clinical Context
A typical patient is an adult with one or more focal hepatic tumors (primary hepatocellular carcinoma or limited metastatic lesions, often from colorectal cancer) deemed amenable to thermal ablation. The patient presents after cross-sectional imaging (multiphasic CT or contrast-enhanced MRI) showing liver lesions 0.5–5.0 cm in size, or after multidisciplinary tumor board review recommending local control. Preoperative workup includes liver function tests, coagulation profile, oncology staging, and anesthesia evaluation. The procedure is performed in an operating room or hybrid interventional suite under general anesthesia or monitored anesthesia care. The surgeon or interventionalist gains laparoscopic access to visualize and mobilize the liver, confirms lesion location with intraoperative ultrasound, and applies radiofrequency ablation probes to achieve thermal destruction of tumor tissue. Typical intraoperative workflow includes trocar placement, laparoscopic ultrasound localization, probe placement, energy application in overlapping ablations if needed, hemostasis, and closure. Postoperative care includes recovery room monitoring, analgesia, liver enzyme surveillance, and follow-up imaging to assess treatment response. Expected sites of service are an inpatient operating room or hospital outpatient surgical suite depending on patient comorbidity and payer policy.
