Summary & Overview
CPT 43261: ERCP Diagnostic Endoscopy with Biliary/Pancreatic Biopsy
CPT code 43261 represents an endoscopic retrograde cholangiopancreatography (ERCP) procedure performed with retrograde injection of contrast into the biliary tree and with one or more biopsies of suspicious tissue. This combined endoscopic and fluoroscopic diagnostic exam is used to visualize the gallbladder, bile ducts and pancreas, and to obtain tissue for histologic evaluation. The code is clinically important nationally because ERCP with biopsy is central to diagnosing obstructive jaundice, biliary strictures, cholangitis, and suspected biliary or pancreatic malignancy.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of the clinical context for CPT code 43261, typical sites of service, and the common operational considerations for billing this procedure. The publication outlines benchmarkable elements such as utilization settings, documentation elements that support medical necessity, and coding relationships relevant to endoscopic and fluoroscopic diagnostic services. It also highlights policy and coverage topics that commonly affect authorization and reimbursement for advanced diagnostic ERCP procedures.

Billing Code Overview
CPT code 43261 describes a diagnostic endoscopic procedure that combines an upper endoscopy with retrograde injection of contrast material into the biliary ducts to obtain fluoroscopic images of the gallbladder, pancreas, and bile ducts. The procedure also includes one or more biopsies of suspicious tissue obtained during the exam.
-
Service type: Diagnostic endoscopic retrograde cholangiopancreatography (ERCP) with biopsy
-
Typical site of service: Hospital outpatient department or ambulatory surgery center, and may also occur in endoscopy suites where fluoroscopic imaging is available
Clinical & Coding Specifications
Clinical Context
A 62-year-old patient presents with progressive jaundice, right upper quadrant abdominal pain, and abnormal liver function tests suggestive of obstructive biliary disease. Noninvasive imaging (abdominal ultrasound and MRCP) demonstrates a suspected biliary stricture at the common bile duct with biliary dilation. The gastroenterology team schedules an endoscopic retrograde cholangiopancreatography with biopsy to evaluate the biliary tree, obtain direct cholangiographic imaging, sample suspicious lesions, and, if needed, perform therapeutic maneuvers.
The clinical workflow: the patient undergoes pre-procedure assessment including informed consent, NPO status confirmation, medication reconciliation (anticoagulation management), and anesthesia evaluation. In the endoscopy suite, under monitored anesthesia care or general anesthesia, the endoscopist performs upper endoscopy to reach the ampulla, cannulates the biliary system, injects contrast for fluoroscopic cholangiography, documents ductal anatomy and any filling defects or strictures, and takes targeted endoscopic biopsies of suspicious mucosal or intraductal lesions. Post-procedure, the patient is monitored for sedation recovery and complications (pancreatitis, bleeding, infection, perforation) and given follow-up instructions including pathology result review and potential staging or therapeutic planning.
