I recently got a claim rejected that had two procedure codes on it, with the second procedure code having modifier 59, for separate, distinct service. When I called to appeal, to Horizon BCBS, they told me that as of 1-1-08, they no longer recognize modifier 59. When asked what modifier I should use to show two separate procedures, their response was they couldn't tell me! Has anyone else heard of this?? I know you have to back up the use of the modifier, which I was prepared to do with the office notes, but not allowing it at all???
