Summary & Overview
CPT 47125: Hepatectomy, Left Lobe Resection
CPT code 47125 represents a major hepatic surgical procedure — left lobectomy with hepatectomy — used to remove diseased or damaged liver tissue for conditions such as metastatic malignancy, large benign tumors, or traumatic injury. This code is clinically significant because hepatectomy is a high-cost, high-acuity inpatient surgical service with implications for surgical staffing, perioperative care pathways, and payer coverage policies across the country. Key national payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.
Readers will find a concise overview of the clinical context and typical site of service, plus operational and billing considerations relevant to hospitals and surgical practices. The publication summarizes reimbursement and utilization benchmarks where available, common modifier usage, and payer policy themes that affect authorization and claims adjudication. It also highlights clinical and administrative issues important to coding accuracy, documentation of medical necessity, and postoperative resource use. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 47125 describes a hepatectomy with total resection of the left lobe of the liver, a surgical procedure to remove part of the liver. Clinical indications may include metastatic cancer, hepatic adenomas, large hemangioma, or massive hepatic trauma necessitating resection.
-
Service type: Major surgical resection of hepatic tissue (hepatectomy)
-
Typical site of service: Inpatient hospital operating room with postoperative inpatient recovery
Clinical & Coding Specifications
Clinical Context
A 58-year-old patient with a history of colorectal cancer presents with a solitary enlarging hepatic lesion on surveillance imaging. Multiphase CT and MRI characterize a 6.5 cm lesion in the left hepatic lobe suspicious for metastasis. The hepatobiliary surgery team elects to perform a formal left hepatectomy (resection of hepatic segments II, III, and IV) for curative intent. Preoperative workflow includes hepatology and anesthesia clearance, coagulation assessment, liver function testing (including MELD/Child-Pugh considerations), and planning for intraoperative ultrasound and vascular control techniques. Intraoperatively, the surgeon performs mobilization of the left lobe, inflow and outflow control, parenchymal transection with hemostatic adjuncts, and complete resection of the left hepatic lobe. Postoperative care includes monitoring in a step-down or intensive care setting for hemodynamics, serial liver function tests, pain control, DVT prophylaxis, and early mobilization. Pathology evaluation of the specimen confirms metastatic adenocarcinoma with negative margins. Adjuvant oncology consultation follows for systemic therapy decisions.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when the hepatectomy requires substantially greater work, time, or complexity than usual and documentation supports the increased services. |
