Yes, premixed. We are simply providing it (being billed by the vendor) and administering it. I concur with your thoughts of using 95120 vs. 95165. I feel if it is given to us premixed then billing 95165 would be fraudulent since 95165 includes in the definition "supervision of the preparation." If it is premixed, how can we bill for "preparation" or "supervision of preparation"? Do you have a background in allergy?
