Summary & Overview
HCPCS C7542: ERCP with Biopsy and Endoscopic Cannulation of Papilla
HCPCS Level II code C7542 denotes an endoscopic retrograde cholangiopancreatography (ERCP) with biopsy, including endoscopic cannulation of the papilla and direct visualization of the pancreatic and/or common bile ducts. As an advanced endoscopic diagnostic and therapeutic procedure, ERCP with biopsy is clinically important for diagnosing and managing biliary and pancreatic disease, including strictures, malignancy evaluation, and obstructive processes. Nationally, this code represents a specialized service performed in hospital outpatient departments and ambulatory endoscopy suites where fluoroscopy and endoscopic expertise are available.
Key payers in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical context of C7542, how payers commonly categorize and cover ERCP-biopsy services, and benchmarks for site-of-service utilization and billing patterns where available. The publication also summarizes relevant billing considerations, common modifiers encountered in practice, and service-line implications for gastroenterology and surgical endoscopy departments. Data not available in the input is noted where applicable, and the content is presented for a national audience without state-specific references.
Billing Code Overview
HCPCS Level II code C7542 describes an endoscopic retrograde cholangiopancreatography (ERCP) with biopsy, single or multiple, with endoscopic cannulation of the papilla and direct visualization of the pancreatic and/or common bile ducts. This procedure involves endoscopic access to the duodenum, cannulation of the ampulla of Vater (papilla), contrast injection and endoscopic visualization of the biliary and pancreatic ductal systems, and collection of one or more biopsy specimens.
Service type: Diagnostic and interventional endoscopic procedure (ERCP) with biopsy
Typical site of service: Hospital outpatient department or ambulatory endoscopy suite (endoscopy/operating room with fluoroscopic capability)
Clinical & Coding Specifications
Clinical Context
A 58-year-old patient with progressive right upper quadrant abdominal pain, jaundice, and abnormal liver function tests is scheduled for endoscopic retrograde cholangiopancreatography with biopsy. The patient underwent pre-procedure evaluation by a gastroenterologist, including history, physical, coagulation assessment, and informed consent. On procedure day the patient is placed under moderate sedation or monitored anesthesia care in an endoscopy suite. Under fluoroscopic guidance, the endoscopist performs endoscopic cannulation of the major papilla, injects contrast to visualize the biliary and pancreatic ducts, and obtains targeted mucosal or ductal biopsies of suspicious strictures or filling defects. Specimens are submitted to pathology. Post-procedure monitoring includes assessment for complications such as pancreatitis, bleeding, infection, or perforation; discharge instructions address signs of complications and follow-up for pathology results and potential therapeutic interventions (stenting or surgical referral) as indicated.
