We perform screening mammograms with additional diagnostic mammography on the same day for specific patients (transplant, surgical) and utilizing the -59 and -GG modifiers for these diagnostic mammogram scenarios. My question is... there is also a corresponding CAD charge for both screening mammography and diagnostic mammography. If we are running the CAD (computer-assisted detection device) program on the four routine (CC and MLO) views of the screening BILATERAL mammogram, would charging the diagnostic CAD for the magnification/spot compression, rolled views, etc. of the LEFT breast be considered double-dipping or repeating the CAD unnecessarily? Or should this too be -59 and -GG modifier worthy?
