Ask Dr. Z

I was reading the Q&A ID # 10826 in regards to the use of 74420 if the RPG is used to guide the stent placement. The answer confuses me as most of IR coding prohibits coding angiograms for guidance, and this in essence is the S&I to an pyelogram to guide the stent placement. Could you please clarify that we can report the 74420 in this case? The actual RPG code 52005 edits and is bundled with the stent placement, and it confuses me that we can code the S&I when we can't show its parent code and since it's used to guide the stent, it seems like the S&I 74420 should be bundled as well.
