Ok, so I know Medicare part "A" (hospitals) is free once I hit that age. Part "B" I have to pay for. I think the Part "B" charge for this year is $145 a month. (Income of less than $85k.) There is a $200 annual deductible. After that, I am responsible for 20% of Medicare-approved costs.* (I don't think there's a cap on that - the bill can go through the roof?) Part "B" covers doctor services (including most doctor services while hospitalized), outpatient therapy, and durable medical equipment (DME). I don't believe it covers the cost of all drugs/medications, but does cover some. For what Part "B" doesn’t cover in a hospital outpatient setting, I would have to pay pay 100% for the drugs - unless I have Part "D" or other prescription drug coverage. With Part "D" I'd pay 25% of the cost of the medications.
So, all of the above is useless outside the USA. But inside the USA, I'm thinking I'd really want to be on Parts A, B, ...and D. So, A & B are "regular" Medicare, and Part D is optional, for added cost. I've no clue how to find that cost.
And then there is Plan "C", the Medicare Advantage plan. It is run by private insurance that bills Medicare for anything Medicare would have paid for and then covers most of the rest? I'd pay them and they'd pay my Parts B and D?
My ex-employer has a set of insurers they pay towards. If a retiree is out of California, the insurance paid for by them is limited to two companies. Once you hit Medicare age, which is looming for me, if you are out of California, they shunt you over to an entity with whom they have contracted to arrange Medicare coverage for you, and drop $3k into a flexible spending account to pay towards any associated costs. I've been trying to talk to the entity for some time now to get an idea of the costs of their plans, and how much more than that $3k I'm going to have to fork over for full medical cover once I'm back in the US of A, but they will not discuss any of the costs of any of their plans until I am actually in-country and ready to apply. So I cannot budget at all - VERY frustrating!
*Medicare-approved costs. That phrase worries me. The medical system in the US routinely charges quite a bit for services, and I'm wondering what happens if the cost of services billed exceeds what Medicare will pay? Balance billing? I know some states have laws prohibiting billing for charges above what you expect your insurance to pay - California (A.B. 72: Out of Network Coverage and A.B. 1611 Emergency Hospital Services: Cost), Connecticut, Florida, Illinois, Maryland, and New York. Do they cover Medicare as well?
We are still not sure where we're going to end up. Right now the two most likely places are California or New York. But if we end up in another state, I'm wondering if I have to worry about balance billing? [The number of states we would go to is limited by the Daughter's situation. If she's not working in a position with private insurance and not earning enough to buy it, or is not in school, she will have to rely on Medicaid. Not all states expanded Medicaid coverage to low-income adults, so there are still some states where she would have no resource to medical care. Hence we wouldn't move to one of those on a bet.]
And, having dealt with private insurers and also Medicaid in the past, I know that not all medical care providers will accept all insurances. And a very high percentage of non-hospital providers do not accept Medicaid patients. So, is it the same for Medicare? Am I going to have a hard time finding a doctor who'll accept Medicare?
