Are you billing a Medicare Advantage plan for DME, that's what it sounds like, can you clarify? If you're billing original Medicare for DME it has to go to the regional DME MAC. If you're billing and Advantage plan then there should be a subscriber and group # you would use that and not the Medicare #.

Aside from that if you can clarify I can assist you further.
