How much money are you allowed to have in bank for Medicare?

Right. Medicare is not based on income or assets.

so there are no money restrictions on Medicare?. Just want to confirm.
thanks

Medicare is a Federal program available to all who have paid into it, once they are 65. Perhaps you are talking about Medicaid, which is a program for people of any age with little to no money. How much you can have and still get Medicaid varies by State.
