    Hi, Still working on getting our ASC open. I was told that 1X a month we will be doing colonoscopies with propyphol (general anesthesia). Would I code this with a modifier 23? Thank you for your help. Lora

    23 would not apply since it is not unusual; however beware of payors. Medical necessity must be well documented or the ASA will not be paid.

    Are you wanting to add the 23 modifier to the procedure code (ie 45378-23)? Are you wanting to bill for the medication??

    The colonoscopies will most likely be done under MAC (monitered anesthesia care) and would not use a modifier 23. Modifier 23 is used for physicians and not ASC facilities and MAC is not unusual for colonoscopies.

    cconroycpch is correct, I wasnt thinking that far in advance (long week and brain dead). The 23 modifier is NOT an ASC modifier therefore its not even a consideration in that setting.

    thanks cconroycpch
