Which is the best one?
Just look for it online, there are many medicare plans.
Medicare Advantage plans will generally pay the Medicare fee for dialysis, but sometimes they negotiate a slightly higher fee in order to get the provider to contract with them. Medicare Part B (Medical Insurance) covers a variety of services if you get routine dialysis in a Medicare-certified dialysis facility. For example, Part B covers ESRD-related laboratory tests and drugs (like heparin, topical anesthetics, and erythropoiesis-stimulating agents used to treat anemia related to your ESRD). I got a part G from here https://www.medisupps.com/medicare-supplement-plans/medicare-supplement-plans-2022/ , you should check it out and see if there is something convenient for you.
