Summary & Overview
CPT 47760: Biliary-Enteric Bypass for Biliary Obstruction
CPT code 47760 denotes a surgical biliary-enteric bypass that connects the extrahepatic bile ducts to the small intestine to reestablish bile flow when biliary obstruction is present, frequently from malignancy. This operation is clinically significant because it addresses obstructive jaundice, reduces cholestasis-related complications, and can be palliative or part of curative surgical strategies. Nationally, this code is relevant to hospital surgical services, surgical oncology, and hepatobiliary specialty care.
Key payers addressed in this publication include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical context for the procedure, typical sites of service, and the common billing modifiers associated with major surgical services. The report presents national benchmarking concepts, common payer coverage considerations, and coding practice points that affect claim adjudication and reimbursement pathways. Where input data are unavailable, the publication notes that explicit details are not provided.
This summary equips revenue cycle professionals, surgical departments, and policy analysts with a clear understanding of what CPT code 47760 represents, why it matters in clinical and billing workflows, and which payers are typically involved in coverage and payment discussions.
Billing Code Overview
CPT code 47760 describes a surgical procedure that creates an external connection between the biliary ducts outside the liver and the small intestine to restore bile flow in the setting of biliary obstruction, most commonly due to a tumor. This procedure is a form of biliary-enteric bypass intended to bypass an obstruction and permit passage of bile into the gastrointestinal tract.
-
Service type: Surgical biliary bypass / biliary-enteric anastomosis
-
Typical site of service: Operating room or surgical suite within an acute care hospital; may also occur in specialty surgical centers equipped for major abdominal operations
Clinical & Coding Specifications
Clinical Context
A typical patient is an older adult presenting with progressive jaundice, pruritus, clay-colored stools, and unintended weight loss. Imaging (ultrasound, CT or MRI) demonstrates extrahepatic biliary obstruction most commonly due to a hilar cholangiocarcinoma or pancreatic head malignancy. Endoscopic retrograde cholangiopancreatography (ERCP) with stent placement may be attempted first; when endoscopic or percutaneous decompression is not feasible or has failed, the surgical team performs a surgical biliary-enteric bypass — connecting the extrahepatic biliary ducts to the jejunum (hepaticojejunostomy or choledochojejunostomy) to re-establish bile flow. The procedure typically occurs in an operating room under general anesthesia with an attending hepatobiliary or general surgeon, nursing staff, and intraoperative anesthesia team. Preoperative workflow includes liver function testing, coagulation assessment, cross-sectional imaging, and multidisciplinary discussion with oncology when tumor-directed therapy is planned. Postoperative care includes monitoring for bile leak, infection, bilirubin trends, pain control, and staged transition from intravenous to oral intake before discharge to home or skilled nursing when needed.
