We bill 64561 for the percutaneous implantion of an electrode array. The patient always comes back to have it removed, as it is temporary, during the 10 day global period. According to AUGS, this is not separately coded as it is typically done within this time frame. The doctor and my supervisors insist that we bill this. I say we shouldn't, but the other coder in the office will bill 64585-58 and it gets paid. I would like to hear how others handle this, and if she is correct on adding the modifier to get it paid.
