Medicare and part B will pay for IVIG depending on the diagnosis. MG is covered but the doctor has to submit continuing proof of necessity and documentation to CMS. Medicare will only cover IVIG in the home for myasthenia if you are a homebound patient. You must report to an outpatient infusion center for 100% coverage if you have myasthenia and can get to an outpatient setting. If they do cover in the home they will cover the drug only and you will end up paying for the nursing care and supplies on your own if part B refuses to cover it. If you have Immune Deficiency Disease home infusion is covered. It would be very convenient to have it in the home but safety wise I feel comfortable going to the hospital. I have been doing this weekly for 6 years and it has given me my life back. Read the booklet In print or online that Medicare sends out - there is a section on IVIG and that might help.
