No, Medicare does not cover the cost of nurses for home infusion. The only way to get full coverage is to go to an infusion center. For home infusion, Medicare Part D drug coverage pays 80% of the cost of the IVIG fluid. I get 40 grams five times in every four-week cycle. I pay almost $800 a month out of pocket for the IVIG and more than $2,000 a month for nursing service. My monthly out of pocket bill is more than $3,000. I take Gamunex, and not a single infusion center near me uses it. They all use either Privigen or Gammagard. I urge you to go to an infusion center if you can’t afford the cost of home infusions.
Once you’re on Medicare, you can’t get a “full insurance plan” from any private insurer. You can buy supplemental plans to cover the 20% that Medicare Part A and Part B don’t cover, and you can get Part D to cover drugs. You can’t go back to private insurance.
