If an insurance requires the PT modifier for a screening colonoscopy that turns therapeutic would it be appropriate to use the XS modifier if two polyp removal techniques are used or would you use the 59 modifier? I have been using the PT/XS combination on Medicare and some commercial and my coworker has been using the PT/59 combination on commercial. She is under the impression that the XS modifier is only for Medicare. Please advise. Thank you.
