No since its not a repeat lab. its 2 different types of lab tests. Must be CLIA certified lab to perform anything other than 80305.If a G0480- G0482 is billed with a 80307 then would mod 91 then need to be added? And if 80307 is billed with an office visit then what modifier needs to be used? I'm having issues with Aetna Better Health on processing and paying the 80307 we had QW attached but she told me that it needs a modifier that's just not the correct one.
