> Every single Advantage patient is enrolled in "oringinal medicare" parts A and B, the only difference is those parts are administered by private insurance
Again, it seems you're confused about what Medicare Advantage is. Medicare Advantage essentially replaces all Medicare coverage - parts A, B, and (usually) D. So no, Part C patients are not enrolled in Original Medicare in any sense. They are enrolled in Medicare, but not Original Medicare.
> Yes it's good but is has nothing to do with insurance creating the market conditions that created the drug coverage,
I'm not talking about drug coverage. Medicare Advantage provides a superior (in every measurable sense) way to obtain Part A and B benefits than Original Medicare does. That has nothing to do with drug coverage.
> its law and subsidies.
It's not a matter of "subsidies". Medicare Advantage is not subsidized by the government. The government pays private insurers a fixed amount that corresponds to what Original Medicare would "receive" for each patient, but that's not a subsidy. And when we say that Medicare Advantage outperforms Original Medicare on cost, we're saying that Medicare Advantage is able to achieve better outcomes for the same amount of money.
If you think that's just a fluke, then look at Medicaid. The same pattern holds with Medicaid, where privately managed plans again consistently outperform the government plans, even though the array of requirements differs widely.
> especially when you already minimized >80% of the patients get mandated drug coverage.
The drug coverage isn't "mandated" for Medicare Advantage patients, any more than it is "mandated" for Original Medicare patients who enroll in a Part D plan or a Medigap plan. Medicare Advantage patients who don't receive prescription coverage can get a Part D plan just like Original Medicare patients can.
Maybe you're trying to say that there's a beneficial selection occurring, but that's also wrong. Part D is well-segemented
That argument would basically boil down to "Medicare Advantage is only better than Original Medicare because most Medicare Advantage patients receive drug coverage", which makes no sense because (a) the same companies provide Medicare Advantage and Part D benefits (and oftentimes using same plans), and (b) Medicare Advantage provides superior coverage and quality (and at a lower price) when compared to Part D enrollees with the same prescription coverage.
Honestly, the existence of Part D is, if anything, proof positive of this effect, because it makes it so easy to tease out the difference between receiving Part A/B coverage through Original Medicare and receiving equivalent coverage through Medicare Advantage.
> Though it will become clearer as the insurance continues to consolidate and Medicare patients will only be able to go to doctors, hospitals and pharmacies owned by the insurer, because that's where it's going for Medicare Avantage patients
That's the way the entire industry is headed as a direct result of the ACA. But even that's still a lot better than Original Medicare where patients struggle to get appointments at all.
