When would I use modifier 51 instead of modifier 59?
If you would have asked me that question 10 years ago, I would have told you not to use a 51 modifier because it causes bundling reimbursement. But 51 is now in your CPT book for when you are doing skin or endoscopic procedures. There is an indication that you should use a 51 modifier instead of a 59 modifier.
