Official Description

Endoscopic retrograde cholangiopancreatography (ERCP); with biopsy, single or multiple

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

Endoscopic retrograde cholangiopancreatography (ERCP) is a specialized diagnostic procedure that allows for the examination of the pancreatic and biliary ducts, which are critical pathways for the drainage of digestive fluids from the pancreas, liver, and gallbladder. This procedure is particularly valuable in diagnosing various conditions affecting the bile ducts, including obstructions, infections, and malignancies. During an ERCP, a flexible endoscope is inserted through the patient's mouth, traversing the esophagus and stomach, and advancing into the duodenum, where the pancreatic duct and common bile duct converge at a location known as the ampulla of Vater. At this juncture, a smaller catheter is introduced through the endoscope to cannulate the ampulla of Vater, allowing for the injection of contrast dye into the ducts. This contrast material is essential for visualizing the anatomy and any pathological changes within the common bile duct, biliary tract, gallbladder, and pancreas via X-ray imaging. The procedure not only aids in identifying issues such as gallstones, strictures, leaks, scarring, or tumors but also facilitates the collection of tissue samples through brushing or saline washing techniques. The use of CPT® code 43261 is appropriate when one or more biopsies are performed during the ERCP, enabling healthcare providers to obtain histological samples for further analysis and diagnosis.

1. Indications

The procedure of endoscopic retrograde cholangiopancreatography (ERCP) with biopsy is indicated for a variety of clinical scenarios where there is a need to investigate the health of the biliary and pancreatic systems. The following conditions may warrant the performance of this procedure:

  • Suspected Biliary Obstruction - When there is a clinical suspicion of blockage in the bile ducts, which may be due to gallstones, tumors, or strictures.
  • Cholestasis - In cases where there is a reduction or stoppage of bile flow, leading to jaundice and other symptoms.
  • Pancreatitis - To evaluate the underlying causes of pancreatitis, particularly when there is a suspicion of obstruction in the pancreatic duct.
  • Abnormal Imaging Results - When imaging studies such as ultrasound or CT scans suggest abnormalities in the biliary or pancreatic ducts.
  • Suspicion of Malignancy - In patients where there is a concern for cancer in the biliary tract or pancreas, ERCP can help in obtaining tissue samples for diagnosis.

2. Procedure

The procedure of endoscopic retrograde cholangiopancreatography (ERCP) with biopsy involves several critical steps to ensure accurate diagnosis and treatment. The following outlines the procedural steps:

  • Step 1: Patient Preparation - Prior to the procedure, the patient is typically required to fast for several hours. Sedation is administered to ensure comfort and minimize anxiety during the procedure.
  • Step 2: Endoscope Insertion - The physician carefully inserts a flexible endoscope through the patient's mouth, guiding it through the esophagus and stomach, and into the duodenum. This allows access to the ampulla of Vater.
  • Step 3: Cannulation of the Ampulla - Once the endoscope reaches the duodenum, a smaller catheter is introduced through the endoscope. The physician cannulates the ampulla of Vater, which is the point where the pancreatic duct and common bile duct converge.
  • Step 4: Contrast Injection - Contrast dye is injected through the catheter into the biliary and pancreatic ducts. This step is crucial for visualizing the ducts on X-ray images.
  • Step 5: Imaging - X-ray images are taken immediately after the contrast is injected to assess the anatomy of the ducts and identify any abnormalities such as gallstones, strictures, or tumors.
  • Step 6: Biopsy Collection - If necessary, the catheter may be advanced over a guidewire into the common duct, biliary tract, gallbladder, or pancreas to collect tissue samples. This is done through brushing or by injecting saline solution to wash cells from the targeted area.

3. Post-Procedure

After the completion of the ERCP with biopsy, patients are typically monitored in a recovery area until the effects of sedation wear off. It is common for patients to experience some throat discomfort or mild abdominal pain following the procedure. The healthcare team will provide instructions regarding diet and activity level post-procedure. Patients may be advised to avoid solid foods for a short period and to gradually resume normal activities. Follow-up appointments may be scheduled to discuss biopsy results and any further management based on the findings from the ERCP.

51 Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d).
59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
XS Separate structure, a service that is distinct because it was performed on a separate organ/structure
XU Unusual non-overlapping service, the use of a service that is distinct because it does not overlap usual components of the main service
GC This service has been performed in part by a resident under the direction of a teaching physician
22 Increased procedural services: when the work required to provide a service is substantially greater than typically required, it may be identified by adding modifier 22 to the usual procedure code. documentation must support the substantial additional work and the reason for the additional work (ie, increased intensity, time, technical difficulty of procedure, severity of patient's condition, physical and mental effort required). note: this modifier should not be appended to an e/m service.
52 Reduced services: under certain circumstances a service or procedure is partially reduced or eliminated at the discretion of the physician or other qualified health care professional. under these circumstances the service provided can be identified by its usual procedure number and the addition of modifier 52, signifying that the service is reduced. this provides a means of reporting reduced services without disturbing the identification of the basic service. note: for hospital outpatient reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well-being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use).
53 Discontinued procedure: under certain circumstances, the physician or other qualified health care professional may elect to terminate a surgical or diagnostic procedure. due to extenuating circumstances or those that threaten the well being of the patient, it may be necessary to indicate that a surgical or diagnostic procedure was started but discontinued. this circumstance may be reported by adding modifier 53 to the code reported by the individual for the discontinued procedure. note: this modifier is not used to report the elective cancellation of a procedure prior to the patient's anesthesia induction and/or surgical preparation in the operating suite. for outpatient hospital/ambulatory surgery center (asc) reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use).
58 Staged or related procedure or service by the same physician or other qualified health care professional during the postoperative period: it may be necessary to indicate that the performance of a procedure or service during the postoperative period was: (a) planned or anticipated (staged); (b) more extensive than the original procedure; or (c) for therapy following a surgical procedure. this circumstance may be reported by adding modifier 58 to the staged or related procedure. note: for treatment of a problem that requires a return to the operating/procedure room (eg, unanticipated clinical condition), see modifier 78.
78 Unplanned return to the operating/procedure room by the same physician or other qualified health care professional following initial procedure for a related procedure during the postoperative period: it may be necessary to indicate that another procedure was performed during the postoperative period of the initial procedure (unplanned procedure following initial procedure). when this procedure is related to the first, and requires the use of an operating/procedure room, it may be reported by adding modifier 78 to the related procedure. (for repeat procedures, see modifier 76.)
79 Unrelated procedure or service by the same physician or other qualified health care professional during the postoperative period: the individual may need to indicate that the performance of a procedure or service during the postoperative period was unrelated to the original procedure. this circumstance may be reported by using modifier 79. (for repeat procedures on the same day, see modifier 76.)
