Hello, My doctor approved me to start IVIG treatments for Parvovirus B19, however, my insurance doesn't cover it there since he is out of network, so it is way too expensive for me. I've been looking for other places that perform IVIG that take insurance. I tried a hematologist and they won't do it since my reason doesn't fall under hematology. I've now booked an appointment with a rheumatologist who does IVIG. But he has to approve it before I can get it of course. Rheumatology deals with immune system disorders, so do you think I would be able to get the treatments there? Or where else would I possibly be able to get it done? Anyone familiar with IVIG, please help. I am in southeastern PA. This is so frustrating.
