Cystogastrostomy with Stent Insertion
A patient diagnosed with walled off pancreatic necrosis and pancreatic pseudocyst adjacent to the stomach body, underwent endoscopic cystogastrostomy using the AXIOS™ Stent system. The endoscope was placed under direct vision, and the stomach wall and pancreatic pseudocyst were punctured under endosonographic guidance. An AXIOS™ stent was placed in close approximation to the walls of the cyst and the stomach through the cystogastrostomy. Dark brown fluid was drained from the stent. A gastroscope was advanced into the stomach under direct visualization, a wire was inserted through the AXIOS™ stent into the cyst cavity under fluoroscopic guidance, and a dilating balloon was then advanced over the wire with successful dilation of the tract. A large necrotic cavity was visualized, and a catheter was placed into the AXIOS™ stent under endoscopic and fluoroscopic guidance to maintain patency. What is the appropriate code assignment for cystogastrostomy using the AXIOS™ stent? Is it appropriate to report additional codes for balloon dilation of the tract and dilation of the AXIOS™ stent? If so, what are the correct code assignments? ...

Article Overview
This article reviews a gastrointestinal endoscopic procedure involving cystogastrostomy and stent placement for a pancreatic fluid collection near the stomach. It is relevant to coders, auditors, and clinicians working with endoscopy, interventional gastroenterology, and procedure coding because it addresses how to classify a complex minimally invasive service and the documentation elements described in the case narrative.
Why This Topic Matters
Accurate coding for advanced endoscopic drainage procedures depends on correctly understanding the procedural approach, the anatomic target, and the devices used. This article helps readers evaluate the scope of the service and the coding considerations associated with the documented procedure.
