Ask Dr. Z

For the following, do we use the 48999, 49423, and 74984?

"Patient has peripancreatic necrosis and has a drainage and catheter placed. Now they are changing out the catheter and debriding necrotic tissue under fluoro and endoscopic guidance. PROCEDURE: Contrast was injected through both catheters to opacify the collection. Visualized using fluoro. Catheters removed over guidewires; 30 French X-Force sheaths placed with safety wires. Rigid nephroscope advanced through both sheaths to visualize the cavity. Cavity was debrided with forceps and stone retrieval baskets through both sheaths. 22 French drainage catheters were advanced through the sheaths and used to vigorously lavage the cavity with saline, removing copious solid debris. Sheaths were removed, and two new 22 French drainage catheters were placed and sutured. Catheters were connected to bag drainage. Successful fluoroscopically and endoscopically guided percutaneous debridement and lavage of peripancreatic collection."
