Summary & Overview
CPT 47712: Excision of Intrahepatic Biliary Duct Mass with Bile Duct Repair
CPT code 47712 represents surgical excision of an abnormal mass from an intrahepatic biliary duct with repair of the bile duct and submission of the tissue for pathology. This code captures a specialized hepatobiliary surgical service performed when a lesion within the liver’s biliary tree requires removal and diagnostic evaluation. Nationally, this procedure is clinically important for diagnosing and managing biliary neoplasms, strictures, or other obstructive pathology that may impact liver function and oncology care.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of coding definition and clinical context, typical sites of service, and the relevance of the code to surgical and pathology workflows. The publication also outlines common modifiers associated with surgical services (listed separately), typical billing considerations for hospital and ambulatory surgical settings, and how CPT code 47712 fits into hepatobiliary service lines.
The content is intended to support billing and administrative stakeholders, clinical program leads, and policy analysts by clarifying what the code represents, where it is typically performed, and why accurate coding matters for clinical documentation, surgical resource planning, and downstream pathology evaluation. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 47712 describes a surgical procedure to remove an abnormal mass from an intrahepatic biliary duct, with repair of the bile duct as needed and submission of the specimen for pathological evaluation. This procedure involves excision of a lesion within the biliary tree located inside the liver.
-
Service type: Surgical excision of intrahepatic biliary duct mass with bile duct repair
-
Typical site of service: Inpatient or outpatient hospital operating room, or ambulatory surgical center depending on clinical complexity and facility capabilities
Clinical & Coding Specifications
Clinical Context
A 62-year-old patient presents with right upper quadrant pain, intermittent jaundice, and abnormal liver function tests. Cross-sectional imaging (contrast-enhanced CT or MRI) and magnetic resonance cholangiopancreatography identify a suspicious intraductal biliary mass within an intrahepatic bile duct. Percutaneous or endoscopic biliary sampling was nondiagnostic, and the multidisciplinary team recommends surgical excision of the intraductal lesion. In the operating room, the hepatobiliary surgeon performs a targeted intrahepatic bile duct exploration, removes the abnormal mass, performs biliary duct repair as needed (primary repair or ductoplasty), and sends the specimen for frozen section and formal pathology to evaluate for malignancy. Typical perioperative workflow includes preoperative consent, anesthesia evaluation (general anesthesia), intraoperative cholangiography as indicated, specimen submission to pathology, and postoperative monitoring for bile leak, bleeding, and infection. The procedure may occur in an acute hospital operating room or an ambulatory surgical center depending on patient acuity and expected complexity. Common postoperative care includes liver function monitoring, imaging if bile leak is suspected, and coordination with oncology if malignancy is confirmed.
