I work for an orthopedic practice where the physicians see patients and do injections same day all the time. I have been trained to bill the E/M level for the visit and the injection code and append modifier 25 to the E/M level. Recently I went to an E/M workshop and the instructor told me that I have been doing this all wrong and it is not appropriate to even bill the OV with the injection done same day. For example : a New patient comes into the office and is worked up and diagnosed with a trigger finger, the md decides to perform an injection. I would bill 99203 -25 20550- FA (for whichever finger) and then the medications.... but she told me that I should not be billing this way..... but that I should only be billing the injection. Is this true? Can anyone give me insight to this? or forward or direct me to related articles or discussions? thank you so much!
