I know there were new codes for 2011 for cervical fusions. My provider wants to bill 22551, 22554-51 as 22554 is used for purposes of arthrodesis and preparing interspace, not for decompression. My provider indicates pretty clearly in the op note that a diskectomy only was performed, no decompression. Is this something that the insurance should pay for? Should I bill 22554 with mod 59 also? Please help!
