My husband started his Radicava infusion at the hospital, then we transitioned to doing it at home.  He had Medicare, Supplemental and Plan D.  I don’t recall  how much it was, but I feel like almost all of it was covered.  (This was August 2019 – February 2020) I was the one to administer his infusion, and I am not a healthcare professional.  I was incredibly nervous at first, but after having watched the nurses at the hospital, and watching MANY tutorials on YouTube, I became confident and it became very routine.  Steve would have a glass of wine and watch the news during the infusion.  As time went on and Steve’s mobility declined, we were so grateful to be able to do this at home.  I don’t know if this is helpful, but just wanted to share our experience with you.
Best of luck Robert.
