My question is this, so for screening turned diagnostic, you bill the code that was done(removal polyp) and use Z12.11 as primary dx with modifier PT or 33 depending on what insurance it is. So if they have more than one polyp removed by different means, example: 45385 & 45384 & 45380, do you put the mod-pt or 33 on all of them and use primary z12.11 on all of them??
