Ask Dr. Z

Which unlisted code would you use for this case: 47999 for biliary or 44799 for intestine because they went into the duodenum? Also would I skip coding the conscious sedation because the ERCP immediately  follows? "Procedure summary: 1. Informed consent. 2. Conscious sedation with continuous vital sign monitoring provided by the nursing staff with physician supervision. 3. Injection of existing PTC catheter with small volume of contrast. 4. Removal of the existing PTC catheter over a 0.035 C-wire. 5. 4 French Kumpe catheter advanced over the wire to the level of the mid common bile duct. 6. Mid/distal common bile duct stenosis crossed with the Kumpe catheter and 0.035 Glidewire. 7. Kumpe catheter advanced to the level of the third portion the duodenum. 8. Placement of a 0.035 Jag wire to the level of the ligament of Treitz. 9. Jag wire secured to the skin and patient transferred to the endoscopy unit for further intervention."
