Unfortunately, due to the expense of IVIG (my clinic charges about $10,000/treatment), insurance companies do take a little longer to look at it.

Also, IVIG is not an officially recognized treatment for MG - it is considered experimental. My company is self-insured, but they do carry insurance for claims over $175,000. When my claims went beyond that, that insurance company refused to pay for the IVIG because it is "experimental".

When we researched all this, we did find that the "official" word is that it is experimental. Fortunately my doc knows it is the best thing for me!

Good luck and hang in there!
