Reply To: Negative Spinal Tap-Still CIDP?

United Healthcare’s Apheresis Policy is here: https://www.unitedhealthcareonline.com/ccmcontent/ProviderII/UHC/en-US/Assets/ProviderStaticFiles/ProviderStaticFilesPdf/Tools%20and%20Resources/Policies%20and%20Protocols/Medical%20Policies/Medical%20Policies/Apheresis_.pdf

and it includes this statement: “According to the guideline, plasmapheresis is established as effective for severe acute inflammatory demyelinating polyneuropathy (AIDP)/Guillain-Barré syndrome (GBS) and in the short
-term management of chronic inflammatory demyelinating polyneuropathy.”

I noticed when reading both of the UHC Policies that they mention ‘..state-by-state’ considerations. You might try contacting your State Insurance Commissioner for help.
