Use of modifier 57 (FUD 90)

I work for a couple of general surgeons and do the majority of the billing for them. Here and there we receive a denial mainly due to the insurance company's attempt to get by without reimbursing our provider, nothing that an appeal can't append.

In the office we may perform a procedure (0-10 FUD) following the E&M in which we are able to add modifier "25". For some unknown reason just recently the office manager is instructing me to use both "57" and "25" on everything performed in office! From an anoscope(0 days) to an I & D(10 FUD) she insists that I do it her way...

I have attempted to show her instructional info on when mod "57" is to be used and she refuses to acknowledge it. This is extremely frustrating when I have been educated to code one way which is correct and then instructed to do it another way!!!

Please let me know if there is any possibility that she is correct and I am wrong?

Any input is greatly appreciated!

modifier 25 and 57

No, it would be incorrect to bill an E/M service with both of these modifiers. Even if two services were performed, one with a ten day global and one with a 90 day global, (not bundled) only one E/M modifier would be submitted.
