Reply To: questions from recently diagnosed CIDP

You may have to do the biopsy then, but the insurance company is just hoping for a loophole, in my opinion. The AAN does seem to have a “mandatory” criterion of a nerve bopsy, but this appears to be for research purposes. It is not usual for neurologists to require this when all other indicators are present. I am unable to find a link to the AAN document, because it is available by subscription only. However, here is a link to an interesting report on the usefulness of the nerve biopsy:

Good luck to you. I hope you get the treatment you need soon.
