43260

Endoscopic retrograde cholangiopancreatography (ERCP); diagnostic, with or without collection of specimen(s) by brushing or washing (separate procedure)

Endoscopic retrograde cholangiopancreatography (ERCP) is a specialized endoscopic technique used primarily to diagnose and treat conditions of the bile ducts and main pancreatic duct. CPT 43260 represents the diagnostic version of this procedure. The procedure involves the use of a side-viewing flexible fiberoptic endoscope (duodenoscope) which is passed through the mouth, esophagus, and stomach into the second part of the duodenum. Once the major duodenal papilla (Ampulla of Vater) is visualized, a catheter or cannula is inserted through the endoscope's working channel into the opening of the biliary or pancreatic ducts. A radiopaque contrast medium is then injected retrograde into these ducts under fluoroscopic guidance, allowing the physician to obtain detailed radiographic images. This visualization is crucial for identifying structural abnormalities such as strictures, stones, tumors, or anatomical variations. In addition to imaging, CPT 43260 specifically includes the collection of specimens via brushing or washing for cytological analysis. This is often performed when malignancy is suspected within the ductal system. It is important to note that if a therapeutic intervention, such as a sphincterotomy, stone extraction, or stent placement, is performed during the same session, the diagnostic code 43260 is typically bundled into the more complex therapeutic CPT codes (43261-43278) and should not be reported separately unless specific criteria for a distinct diagnostic procedure are met.

Clinical Indications

  • Evaluation of biliary tree obstruction of unknown etiology
  • Investigation of idiopathic acute recurrent pancreatitis
  • Preoperative mapping of the pancreaticobiliary system
  • Suspicion of biliary or pancreatic malignancy based on imaging
  • Evaluation of symptomatic gallbladder disease when other imaging modalities are inconclusive
  • Assessment of suspected sphincter of Oddi dysfunction
  • Management and diagnosis of postoperative bile leaks
  • Diagnosis and surveillance of primary sclerosing cholangitis

Procedure Steps

  1. Obtain informed consent and administer pre-procedural sedation or general anesthesia
  2. Position the patient in the prone or left lateral decubitus position
  3. Insert the side-viewing duodenoscope through the oropharynx to the duodenum
  4. Identify and position the duodenoscope at the major duodenal papilla (Ampulla of Vater)
  5. Cannulate the common bile duct or pancreatic duct using a catheter or guidewire
  6. Inject radiopaque contrast material under fluoroscopic guidance
  7. Capture radiographic images (spot films) to evaluate ductal anatomy and pathology
  8. Collect specimens via brushing or washing if indicated for cytological analysis
  9. Withdraw the endoscope and monitor the patient for post-procedural complications

Coding Guidelines

  • Code 43260 is designated as a 'separate procedure' and should only be reported when it is the only ERCP procedure performed or is unrelated to other procedures performed at the same session
  • If a therapeutic ERCP procedure (e.g., 43261-43278) is performed during the same session, 43260 is bundled and not separately billable
  • The collection of specimens by brushing or washing is an inherent component of 43260 and should not be reported separately
  • Radiological supervision and interpretation (RS&I) for ERCP is reported separately using codes 74328, 74329, or 74330 depending on the duct visualized
  • Modifier 52 may be appended if the procedure is attempted but the duct cannot be successfully cannulated
  • For ERCP through a stoma, refer to code ranges 44360-44379 or 43260-43278 depending on the specific anatomy involved
