I always coded a screening test when the patient does not have a confirm diagnosis. And if the patient is on medication for a confirm diagnosis then we did not code the lab work under screening, but under a definite diagnosis. We have someone trying to tell us, if a patient comes in for an annual physical - all lab work is put under V70.0, even if the patient has a confirm diagnosis and is under medication for it. Can I please have feed back on how to handle this or where to find the guidelines for it? Thanks
