Is there anyone out there proficient in allergy coding? I have an instance that I've stumbled upon in which a patient was ordered to have allergy injections. The allergist mixed the antigens one day and charged out 95165 x 35 (he mixed 35 doses that day). About a month from that day, the pt presented for an allergy shot and the nurse charged out 95115 and 95120...This is charged this way for about 4 visits. Then at the fifth and sixth visit, they charged out 95117. Then about the next 5 visits after that, they charged out pxs 95115 and 95120... I am confused as to why they are charging out the 95115 and 95120 at each injection when the allergist mixed 35 doses and charged for them?? I have read up on these codes and it seems to me if the allergist is charging out that 95165 x 35 for the antigens (35 doses) then they shouldn't be charging the 95120 in addition if they are giving a single injection. Am I correct?? This 95120 should only be charged if they were mixing the single dose of antigen for that injection right there at the time of the injection correct? if they charged out the 95165 then are charging the 95120 each time isn't it like they're charging double for the antigen dose? If anyone who is proficient with coding allergy could let me know what they think in addition to any confirming documentation they may have, I would really appreciate it!
