Endoscopic hepaticogastrostomy with stent
A patient with a bile duct obstruction presented for an upper GI endoscopic ultrasound. The endosonoscope was introduced through the mouth, and advanced to the second part of the duodenum. The examination found a large collection of peritoneal fluid and dilation of the left intrahepatic bile ducts. The decision was made to create a hepaticogastrostomy. Once an appropriate position in the stomach was identified, the common wall between the stomach and the left intrahepatic duct were punctured with a needle. The biliary tree was injected with contrast and a cholangiogram was obtained under fluoroscopy. A glidewire was threaded into the left intrahepatic duct. The hepaticogastrostomy opening was dilated with a 4 mm balloon, which was then followed by insertion of a biliary stent. Is creation of the hepaticogastrostomy coded separately from the stent insertion, or inherent to the stent placement? Which CPT code(s) is assigned for the stent insertion via hepaticogastrostomy? ...

Article Overview
This premium coding article focuses on an upper gastrointestinal endoscopic procedure used in the setting of biliary obstruction and intrahepatic duct dilation. It addresses how the service is characterized for CPT reporting, including the relationship between creating the hepaticogastrostomy access and placing a biliary stent, as well as the general coding considerations for a facility setting. The article is aimed at coders and revenue cycle staff who need to understand the scope of the procedure and the CPT reporting framework involved.
Why This Topic Matters
Procedures that combine endoscopic access creation and biliary stent placement can raise coding questions about what is separately reportable versus inherent to the main service. Clear interpretation is important for accurate CPT assignment in facility reporting and for consistent handling of similar interventional endoscopy cases.
