Wiki Modifiers X (EPSU)???

[buppkl]

When multiple X-modifiers apply to a claim, would you use all three or which one would supersede the others? I code for pathology and many times their are two surgical specimens done same day. (i.e. colonoscopy done same day as bronchoscopy, different providers, different specimens, same cpt codes.
The XE, XP, XS all apply. How would it be reported 88305-26, 88305-26/X??

from what i was told by a medicare rep on the phone, "x" modifier would not apply to that situation...i was doing a phone reopening to correct the modifier from XU to XE on an 88305, and was told that since there was another 88305 already billed for DOS, they still wanted the 59 modifier. he said that the "X" modifiers were only for situations affected by NCCI edits. there is really no good information out there on these.
