exploding the myth that Obamacare "takes"

New England Journal Of Medicine: Affordable Care Act Eliminates "Substantial Overpayments" To Medicare Advantage Plans. From an article by Robert A. Berenson in The New England Journal of Medicine:

[T]he currently projected savings come from two main sources: reduced payments to private Medicare Advantage plans and reduced payment updates for hospitals and most other providers. A phased elimination of the substantial overpayments to Medicare Advantage plans, which now enroll nearly 25% of Medicare beneficiaries, will produce an estimated $132 billion in savings over 10 years.

[...]

The Medicare Payment Advisory Commission (MedPAC) has been calling for such fee reductions for years, to keep Medicare Advantage from undermining traditional Medicare.

The ACA also produces nearly $200 billion in savings by assuming that providers can improve their productivity as firms in other industries have done. On the basis of this presumed improvement, the law reduces Medicare's annual "market basket" updates for most types of providers -- a provision that has generated controversy.
