Modifier 59 or XS for Colonoscopy

[dkrisak]

I code outpatient colonoscopies and if I now have a Medicare patient who has a cold forcep biopsy in the descending colon and a hot snare polypectomy in the transverse colon, do I still use 59 on the 45380 or do I now use XS. I believe the large intestine would still be the entire structure/organ so my feeling is to still use the 59. Any thoughts?

I also code outside colonoscopies that my family practice doctor does. I am using the 59 modifier because none of the x modifiers fit that scenario.
