My provider has indicated 4 units of 64450 performed bilaterally (64450-50). Can someone tell me if I bill these all on one line x 4 units or do I need to bill them on separate lines with a "51" modifer(64450-50-51) as I see it has a multiple surgery indicator of "2". My payer is Tricare however we usually try to follow what Medicare wants.
Thanks
