I work for a clinic and we do not give allergy shots but we have a pt that we will be giving them to. Pt is bringing in the allergy med in bottles, we will be drawing the meds and doing the injection. What codes do i use? I was guessing it would be 95117 (we are giving 2 vials/injections) and 96165 for the meds but am not sure how to figure out the units. Was reading posts on the internet and it said for every 1 cc it is 1 unit. So do i add all the measurements of meds together and see how many CC's i get then for every 1 cc is it 1 unit? Please help!!!!!!
