I am having a very difficult time getting the spinal accessory nerve block paid by Medicare. Mainly, the Medicare Advantage Plans. We can no longer use 64412 as it was deleted in 2016. We have to use 64999. I have sent every piece of documentation known to man. I have underlined the piece of the documentation that states the procedure. I have sent copies of the CPT pages in the 2016 & 2017 CPT book showing that this is a deleted CPT and to use 64999. I have sent articles showing that we are to use 64999. I don't know what else to do and how to argue with them. Please help. I will try anything at this point.
