I am reviewing the codes for presumptive and definitive drug testing. The CPT intro to the codes for drug assay, 80305-80307 and 80320-80377 says, "The material for drug class procedures may be any specimen type unless otherwise specified in the code descriptor (eg, urine, blood, oral fluid, meconium, hair)" Do any of the codes in this series define a blood specimen and not include the other materials?

In other words, how would I code for a presumptive or definitive drug test using blood when other specimens (urine, blood, oral fluid, meconium, hair) are not considered medically necessary.

Thanks
