I understand that we bill for both diagnostic and screening mammograms on the same day.

77067 - screening mammogram
77063 - 3d tomo

77066 - diagnostic mammogram
g0279 - 3d tomo

Here is what I am coding for - 77067 & 77063 for the screening mammograms (59 modifier on each) and 77066 and g0279 for the diagnostic mammogram (GG on each for Medicare claims only)

We are getting denials for the g0279.

Can we bill tomo twice per day if its used for a screening mammogram and a diagnostic mammogram?
