I've been on medicare for 4 years and they have covered my IVIG from the beginning. It is covered under Part B and if you have supplemental insurance, everything is covered 100% (depending on your supplemental coverage). I have Plan F and it covers everything Medicare doesn't cover for Parts A and B.

I'm not sure about giving it at home. I have always done it at an Infusion center at the local hospital.

Good luck!
