Ask Dr. Z

What is your code recommendation of this case? "Upper abdomen was prepped and draped in usual sterile fashion. Contrast was injected into patient's indwelling percutaneous pigtail type gastrostomy tube, confirming intragastric location. Catheter hub was cut, and the catheter was removed over Amplatz superstiff wire. A 12 French sheath was advanced into the stomach in order to facilitate fistula brushing, which was performed with 3 mm bristle Cellebrity Cytology Brush over Amplatz wire as sheath was retracted from fistula. Next, Cook enterocutaneous fistula plug was deployed through 24 French sheath within the fistula. Inner disc was in appropriate position along gastric staple line, as confirmed with fluoroscopy and radiography in multiple obliquities. External portion of the plug was secured to abdominal wall with Molnar disc and trimmed. There were no immediate complications."
