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.

Coding Specifications

Modifier	Description	When to Use
`22`	Increased procedural services	Use when the repair required substantially greater work than usual due to extensive dissection or adhesions.
`23`	Unusual anesthesia	Use if general anesthesia was contraindicated and significant medical condition required unusually deep sedation techniques.
`26`	Professional component	Use when reporting a separate professional interpretation component (rare for operative CPT but applicable if a separately billed intraoperative cholangiogram reading is performed).
`50`	Bilateral procedure	Not typically applicable but used when identical procedures are performed on bilateral structures; include only if bilateral biliary ducts are repaired.
`51`	Multiple procedures	Use when `47900` is billed with other distinct procedures during the same operative session.
`52`	Reduced services	Use if the repair was attempted but not completed as described due to unforeseen circumstances.
`53`	Discontinued procedure	Use if the procedure was started but terminated due to patient instability before repair was performed.
`54`	Surgical care only	Use when the surgeon bills only for the intraoperative repair and another provider bills pre/postoperative care.
`55`	Postoperative management only	Use when the surgeon bills only for postoperative management after another surgeon performed the operative repair.
`62`	Two surgeons	Use when two surgeons of different specialties work together as primary surgeons performing distinct portions of the repair.
`66`	Surgical team	Use when a surgical team approach is documented for complex biliary reconstruction.
`78`	Return to operating room for a related procedure during the global period	Use if the patient returns to the OR for revision or complication related to the initial repair.
`80`	Assistant surgeon	Use when a qualified assistant surgeon (e.g., another attending) assists with the repair.
`81`	Minimum assistant surgeon	Use when a minimal assistant participates.
`82`	Assistant surgeon (unplanned)	Use when an unplanned assistant is required due to an emergency or other circumstance.
`AS`	Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery	Use when an advanced practice clinician is documented as the surgical assistant.

Taxonomy Code	Specialty	Notes
207RP0000X	General Surgery	Most common specialty performing open biliary duct repairs.
207L00000X	Vascular Surgery	May be involved when complex ductal reconstruction intersects major vascular structures.
207RK0101X	Hepatobiliary Surgery	Subspecialty focus on liver and biliary tract repairs and reconstructions.
2084P0800X	Trauma Surgery	Performs repairs in the setting of traumatic injury to the biliary tract.
163W00000X	Gastroenterology	May be involved intraoperatively for cholangiography or endoscopic stent placement adjuncts.

`K91.84`	Bile leak	Direct indication for surgical repair when persistent leak from extrahepatic biliary duct is identified.
`T81.31XA`	Disruption of operations wound, initial encounter	Used when postoperative bile duct disruption or wound failure leads to reoperation and repair.
`K80.2`	Calculus of gallbladder with acute cholecystitis	Gallbladder disease can be associated with iatrogenic duct injury during cholecystectomy prompting repair.

Related CPT Codes

CPT Code	Description	Relationship to This Procedure

`47579`	Laparoscopic repair of bile duct injury	Minimally invasive alternative approach for select ductal repairs.
`47580`	Open repair of bile duct injury	Closely related; open approaches for more extensive injuries or when `47900` specifies repair of extrahepatic ducts.
`74328`	Fluoroscopic guidance for cholangiography, intraoperative	Used during `47900` when intraoperative cholangiography is performed to evaluate duct integrity.
`49900`	Exploratory laparotomy, exploratory procedure	May be performed immediately prior to identification and repair of the extrahepatic biliary duct in trauma or unclear abdominal pathology.
