Summary & Overview
CPT 47570: Laparoscopic Cholecystoenterostomy for Biliary Drainage
CPT code 47570 represents laparoscopic cholecystoenterostomy, a minimally invasive surgical procedure that connects the gallbladder directly to the small intestine to restore bile flow when common bile duct obstruction cannot be relieved. Nationally, this procedure is clinically important as a definitive or palliative biliary drainage option for patients who are not candidates for endoscopic or common duct interventions. It impacts surgical service lines, hospital resource utilization, and coding for complex biliary care.
Key payers referenced in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical context for CPT code 47570, typical sites of service, common billing considerations, and how this procedure is situated within surgical and gastroenterology care pathways. The publication summarizes relevant billing benchmarks where available, common modifier usage patterns provided in the input, and policy considerations affecting coverage and site-of-service decisions. Where specific data elements were not supplied in the input, the text notes that those items are not available.
This report is intended for coding professionals, surgical directors, revenue cycle staff, and payers seeking a clear, national-level summary of the procedure, its clinical role, and the billing context for CPT code 47570.
Billing Code Overview
CPT code 47570 describes a laparoscopic cholecystoenterostomy, a surgical procedure that creates a direct connection between the gallbladder and the small intestine to permit bile drainage when an obstruction of the common bile duct cannot be resolved. The procedure is performed using a laparoscope, a tubular instrument with a light source and camera inserted through the abdominal wall, allowing minimally invasive visualization and manipulation.
Service type: Surgical — Laparoscopic biliary drainage procedure
Typical site of service: Hospital operating room or ambulatory surgical center (inpatient or outpatient surgical setting)
Clinical & Coding Specifications
Clinical Context
A typical patient is an adult with obstructive jaundice due to an unresectable distal common bile duct obstruction (for example from malignancy) or impacted stone where endoscopic retrograde cholangiopancreatography (ERCP) is unsuccessful or not feasible. The patient presents with progressive jaundice, pruritus, elevated bilirubin and cholestatic liver enzymes, and intermittent right upper quadrant pain. Imaging (ultrasound, CT, or MRCP) demonstrates biliary dilation and an obstructing lesion. After multidisciplinary evaluation, the surgical team elects to perform a laparoscopic cholecystojejunostomy to decompress the biliary system by creating a direct anastomosis between the gallbladder and the small intestine.
The clinical workflow includes preoperative assessment (labs, coagulation profile, cross-sectional imaging), informed consent discussing risks such as bile leak and infection, perioperative antibiotics, laparoscopic access and inspection, mobilization of the gallbladder, creation of a cholecystojejunostomy (typically to a Roux limb of jejunum or directly to the duodenum/jejunum depending on anatomy), confirmation of bile drainage, hemostasis, and closure. Postoperative care includes monitoring bilirubin trend, pain control, early ambulation, diet advancement as tolerated, and surveillance for complications such as cholangitis, anastomotic leak, or bowel obstruction. Typical sites of service are the hospital operating room or ambulatory surgical center when clinically appropriate and safe for the patient.
