^ Frakt, Austin (December 13, 2011). "Premium support proposal and critique: Objection 1, risk selection". The Incidental Economist. Retrieved October 20, 2013. [...] The concern is that these public health plans will find ways to attract relatively healthier and cheaper-to-cover beneficiaries (the "good" risks), leaving the sicker and more costly ones (the "bad" risks) in fee for service Medicare. Attracting good risks is known as "favorable selection" and attracting "bad" ones is "adverse selection." [...]
MA plans often include dental, vision and health-club benefits that aren’t part of many supplements. Yet people who buy a supplement have the option of buying “stand-alone” Part D prescription drug coverage from any one of several insurers — a feature touted as one of the selling points for Cost plans, too. People in MA plans, by contrast, are limited to Part D plans sold by their MA carrier, Christenson said.
As of January 1, 2016, Medicare's unfunded obligation over the 75 year timeframe is $3.8 trillion for the Part A Trust Fund and $28.6 trillion for Part B. Over an infinite timeframe the combined unfunded liability for both programs combined is over $50 trillion, with the difference primarily in the Part B estimate. These estimates assume that CMS will pay full benefits as currently specified over those periods though that would be contrary to current United States law. In addition, as discussed throughout each annual Trustees' report, "the Medicare projections shown could be substantially understated as a result of other potentially unsustainable elements of current law." For example, current law effectively provides no raises for doctors after 2025; that is unlikely to happen. It is impossible for actuaries to estimate unfunded liability other than assuming current law is followed (except relative to benefits as noted), the Trustees state "that actual long-range present values for (Part A) expenditures and (Part B/D) expenditures and revenues could exceed the amounts estimated by a substantial margin."
More than likely you are going to end up with an HMO type of plan, even if you opt for a Medicare Part C plan that requires you to pay a premium. HMO’s are different from PPO’s, so you’ll need to pay attention. HMO’s require you to stay within network from almost all of you Medical needs. You’ll also need to get a referral from you Primary Care doctor when seeing a specialist most of the time. Therefore, you’re going to want to choose a well-known company that has an excellent Medicare Advantage plan network for you to choose from.
This concept is basically how public Medicare Part C already works (but with a much more complicated competitive bidding process that drives up costs for the Trustees, but is very advantageous to the beneficiaries). Given that only about 1% of people on Medicare got premium support when Aaron and Reischauer first wrote their proposal in 1995 and the percentage is now 35% on the way to 50% by 2040 according to the Trustees, perhaps no further reform is needed.
All insurance companies that sell Medigap policies are required to make Plan A available, and if they offer any other policies, they must also make either Plan C or Plan F available as well, though Plan F is scheduled to sunset in the year 2020. Anyone who currently has a Plan F may keep it. Many of the insurance companies that offer Medigap insurance policies also sponsor Part C health plans but most Part C health plans are sponsored by integrated health delivery systems and their spin-offs, charities, and unions as opposed to insurance companies. The leading sponsor of both public Part C heatlh plans and private Medigap plans is AARP.
