Hi i am new to billing apg i have a question and i cannot get an answer, the facility bills out contact lens which is a v2521 or v2513 – there are a few of them however, these are never payable according to apg, but the representative told me it has to be billed with another procedure code, i dont know what code it is, would this be the contact lens fitting code? To go with the v codes, i dont have enough informaton on this any help with be greating appreciated.
