venom injections

I am inquiring on the proper way of billing venom injections.
We have a patient that is receiving two injections of two different venoms.
We were using 95117 to indicate there was multiple injections. than we used 95130 for the first venom and 95132 for the second venom. some insurance companies pay this others are denying the claim for bundeling. We have read that it should be sent as 95117 with 95133 indicating there were stinging insect venoms.
Does anyone have any additional information as to what is the correct way to submit these types of claims?
