Can you use modifiers with add on codes such as 99135, (Anesthesia complicated by utilization of controlled hypotension)? I'm getting a lot of denials on this.

Thank you:)

This add on code and use of modifiers has been a query for me since long. All that I know is the add on codes should not be appended with Modifier 51 ( Mod- 51 exempt).

I understand the Mod 50 also/ some -26 and so on..
"But NO modifier at all concept" is not there; I am not sure of..
Could any one come out with the correct guidance for this in a crystal clear way please?

What type of modifier are you using with this code? For 99135, the use of modifier 51 is not allowed according to Appendix D in CPT, and in the Introduction section (of CPT) there is an explanation that NONE of the add-on codes are considered a multiiple procedure so you can't use the "multiple procedure" modifier. It would probably help to know what modifier is getting denied...
