Wiki when to bill 74420

[pchamp25]

I am new to coding and I had a question in regards to when to use 74420 and when not to. We are billing out 52356 and 74420 TC. The claim came back as denied for 74420 due to inappropriate modifier. I work in an ambulatory surgery center. After some review, a retrograde pyelogram should be billed out using 52005. Since it can not be billed w/52356 because it is considered as part of the procedure, would I bill 74420 at all? The facility owns all the equipment that was used for the procedure as well. If we are to use 74420 still, from what I can gather, no modifier should be used since we own the equipment and the physician interpreted the results during the procedure.

CPT 74420 is valid with 52351-52355.. But not sure on the Amulatory guidelines are, but the general info is to 74420 when documented.
