It is harder and harder to get Gamunex these days, especially through insurance. I got it for about 16 years and got completely cut off of it a year ago. My neuro tried everything, including several appeals, to no avail.

Medicare can cover it, but only if it's given in an out-patient setting. That would probably be the most successful way to pursue it. You will have to be persistent, as insurers in general are not that helpful. Keep calling your doc and Medicare every day! The squeaky wheel gets the grease!

Good luck!
