This is medicare;
Part A (Hospital Insurance) covers most medically necessary hospital, skilled nursing facility, home health, and hospice care. It is free if you have worked and paid Social Security taxes for at least 40 calendar quarters (10 years); you will pay a monthly premium if you have worked and paid taxes for less time.
Parts B, C, and D are additional and cost the holder, although I suspect there is some subsidy, depending on income, although I have not found that information yet.
Part B (Medical Insurance) covers most medically necessary doctors’ services, preventive care, durable medical equipment, hospital outpatient services, laboratory tests, x-rays, mental health care, and some home health and ambulance services. You pay a monthly premium for this coverage.
Ok, did find Part B is $134 a month for couples earning less than $170,000. $189 deductible.
Medicare Part D (outpatient Prescription Drug Insurance) is the part of Medicare that provides outpatient prescription drug coverage. Part D is provided only through private insurance companies that have contracts with the government—it is never provided directly by the government (like Original Medicare is).
Part D is $34 a month, but there are other options costing more and there is a copay.
Medicare Part C is not a separate benefit. Part C is the part of Medicare policy that allows private health insurance companies to provide Medicare benefits. These Medicare private health plans, such as HMOs and PPOs, are known as Medicare Advantage Plans. If you want, you can choose to get your Medicare coverage through a Medicare Advantage Plan instead of through Original Medicare.
A FRA retired couple I know, pay $800 a month for parts B, D, and C.
I think one of the best ways to limit expense of a government giveaway programs is to make sure the receiving party pays part of that bill, if they have skin in the game there will be less waste.
