Summary & Overview
CPT 47900: Repair of Extrahepatic Biliary Duct, Suture
CPT code 47900 represents surgical repair of an injury to the extrahepatic biliary duct and is used to bill for operative suture repair of bile duct injuries occurring outside the liver. This code is clinically significant because bile duct injuries can lead to serious complications, prolonged hospital stays, and additional interventions; accurate coding supports appropriate clinical tracking and payment for complex hepatobiliary surgery. Key national payers commonly involved in coverage decisions for this service include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.
Readers will find a concise overview of the clinical context for CPT code 47900, including service setting and typical procedural considerations. The publication provides benchmark information on utilization and payment patterns where available, notes of relevant policy updates affecting surgical billing and preauthorization practices, and guidance on coding interoperability with related hepatobiliary procedures. The content is designed for billing managers, surgical clinicians, and policy analysts seeking clear, national-level information about how this code is used and reimbursed across major payers. Data not available in the input will be identified as such in detailed sections.

Clinical & Coding Specifications
Clinical Context
A 48-year-old patient presents after abdominal trauma during a motor vehicle collision with right upper quadrant pain, jaundice, and bile leak on imaging. Diagnostic workup including CT and ultrasound suggests injury to the extrahepatic biliary duct. The patient is taken to the operating room for exploratory laparotomy. The hepatobiliary surgeon identifies a laceration of the common bile duct outside the liver. The provider performs primary repair using interrupted absorbable sutures to approximate the duct edges, ensures patency with intraoperative cholangiography, places a T-tube or internal stent if indicated, and confirms hemostasis before closure. The intraoperative documentation includes time of repair, suture type and size, use of magnification, cholangiogram results, and any additional procedures such as T-tube placement or drainage tube insertion. Postoperative management includes monitoring for bile leak, serial liver function tests, and imaging as indicated. Typical site of service is an inpatient operating room; service type is open surgical biliary duct repair.
