(I also posted this in the cardiology section) I have tried to understand the differences between these two different types of evaluations and when I read the code descriptions they sound so similar I am having trouble discerning how exactly to tell the difference between the two when looking at a device print out, report, and interpretation. Can someone help explain in lay terms what I am looking for in the interpretation or report to help distinguish when I should use each code set? Your help would be so very much appreciated!
