If a patient brings in their own meds for an allergen shot(s), 95115 (single) or 95117 (2 or more) would it be appropriate to add an office visit with a -25 modifier if this was the sole purpose of the visit? Now to add to this there are two dx code V07.1 Desensitization to allergens and V07.2 Prophylactic Immunotherapy which does not make sense to me at all. Does the reading of vitals justify the office visit with the -25 modifier and does the fact that the medication was prescribed by another provider (outside the practice) have any bearing on the coding here? Is the provider forced in this situation to perform some form of evaluation and management therefore warranting the Office visit? I am confused by this because I have a clear answer form what I am being told by my study but people out there are saying in the real world the situation is entirely different and things wont be coded the way I expect. My opinion of this advice is that it is bad advice and is from somebody who has become sloppy in their coding.
