Endoscopic ultrasound with transduodenal approach

Patient presents to have an endoscopic retrograde cholangiopancreatography (ERCP) due to pancreatic duct stones and abdominal pain. However, due to extensive edema of the duodenal wall and luminal narrowing of the second part of the duodenum, cannulation of the major papilla was not successful. Therefore, an endoscopic ultrasound (EUS) was performed. Images of the pancreas showed pancreatitis and stones. The duodenal wall was punctured with a 19-gauge needle to access the pancreatic duct via the duodenum (2nd portion). The pancreaticoduodenostomy was made and balloon dilation was performed. A pigtailed stent was placed in the main pancreatic duct. We are considering CPT code 48999 , Unlisted procedure, pancreas, because of the transduodenal approach and 43260 , Endoscopic retrograde cholangiopancreatography (ERCP); diagnostic, with or without collection of specimen(s) by brushing or washing, for the diagnostic ERCP with modifier 74, Discontinued outpatient hospital Ambulatory Surgery Center (ASC) procedure, after administration of anesthesia, appended. Is there a CPT code for EUS with transduodenal approach to the pancreatic duct with dilation, pancreaticoduodenostomy and stent placement?  ...

Article Overview

This article explains a pancreas-related endoscopic ultrasound procedure performed through the duodenum after ERCP cannulation was not successful. It is relevant to coding staff, auditors, and clinicians who need to understand how the service is being characterized and what broad CPT considerations are raised by the scenario.

Why This Topic Matters

EUS-guided access procedures may require careful code selection when a standard endoscopic approach cannot be completed. Articles like this help readers understand the documentation and service context involved in pancreas and biliary endoscopy coding.
