Hi All -
I have an ongoing debate with a colleague regarding how to bill stone procedures. When they do a combination therapy in the same op session, I bill it as 50590-<laterality>, 52356-59(XU same stone/XS separate stone) - <laterality> and I don't see denials. She swears left, right, and sideways that she was told NEVER do the 59 modifier, do 58 instead. My understanding of the -58 modifier is that it's used on planned subsequent procedures in separate operative sessions, not in the same surgery. Yet, she doesn't understand why hers get denied so often.
How do you bill these? Thanks!
