Reply To: Insurance asking for "Medical Necessity" for IVIg treatments

I had no difficulty getting IvIg. It is a standard treatment for GBS and CIDP. I expect they did require some support for the diagnosis, but I didn’t hear about it. I had Blue Shield of California HMO plan.

Insurers want to know how the diagnosis was made because IvIg is not only expensive, it is scarce. It is not helpful for everything, so it shouldn’t be wasted when it is not an appropriate treatment. Some insurance companies are more difficult than others on matters like this, however.
