modifier 80 and 78 to medicare - Need help with this

[ksrkelly7]

Need help with this. One of our docs assisted an OUTSIDE doc on CPT 35665 and 37618. I know I need modifier 80. Here is the dilemma ....this procedure takes place within the global period for a DIFFERENT procedure that one of OUR docs did. Do I also need modifier 78 along with the 80 because it's in the global period? Again, he assisted an OUTSIDE doc not affiliated with our group and the other doc will be billing as primary. Medicare patient.

Any help would be appreciated.

Thanks,

Kelly

if its the same patient then the 79 modifier will be more appropriate to let the payers know that this is non related
