Ask Dr. Z

Would coding be 36247 (rt hepatic) and 36248 (Segment 8) for the catheter placements only or 36247 only for the below? I am having trouble with the catheter selection is segment 8 going further or an addition placement? A mesenteric catheter was used to select the celiac artery. An arteriogram was performed demonstrating the origin of the right hepatic artery. A microcatheter was used to select the right hepatic artery. An arteriogram and cone beam CT were performed demonstrating tumor enhancement from the segment 8 artery. The microcatheter was used to select the segment 8 artery. An arteriogram and cone beam CT were performed confirming tumor enhancement. The tumor was embolized with 0.5 mL lipiodol. A completion non-contrast cone beam CT was performed confirming adequate tumor staining. I appreciate your help with your this question!
