But that doesn't mean Congress should necessarily listen to them any more than any other lobbyist group that is trying to prevent its ox from being gored. Healthcare spending is likely to devour all federal spending in a couple of decades unless something is done to control its growth, yet even when something like IPAB gets made into a law, Congress tries to kill it before it even exists.
I'm no general defender of the omnibus PPACA, but let's be honest and admit that despite the many changes the law will inflict on the business of healthcare, cost control isn't one of the major ones. In fact, that's the main criticism of the Act. Despite its name, it does very little to make healthcare more affordable.
In fact, IPAB, which was created as a version of the Medicare Payment Advisory Commission (MedPAC) that actually has the teeth to implement its regulations, is perhaps the only piece of the legislation that will actually attempt to hold down medical cost growth. Congress routinely ignores recommendations of MedPAC, so that clearly doesn't work, which is why IPAB was created in the first place.
And yet hospitals, physicians, and many other medical interests are attempting to make it stillborn. Not to worry. They still have lots of time to kill it off, as they will not be subject to IPAB's decisions until 2020!
