We have a new physician and they added something to their NCS/EMG report that I'm not familiar with. There is a note stating "mixed palmar comparison study...of the median nerve...when compared to the ulnar nerve..." The graph is one box with both median and ulnar noted. Would this be 1 NCS or 2 NCS? There are other studies on the note, but this is the one I've never seen before. Any guidance is appreciated.
