CHICAGO, Nov. 5, 2013 /PRNewswire/ -- A majority of our country's middle-income retirees feel that the best aspects of the Affordable Care Act (frequently referred to as Obamacare) is that it eliminates pre-existing condition exclusions (68%); offers a free Medicare annual wellness visits (60%); and includes initiatives to make Medicare more efficient (60%). However, half (52%) of all retirees say one of the worst aspects of the Affordable Care Act (ACA) is the law's requirement that individuals own health insurance or pay a penalty, according to a latest survey by the Bankers Life and Casualty Company Center for a Secure Retirement ® (CSR). A nationwide sample of 800 retired Americans ages 55 and older, with an annual household income of between $25,000 and $75,000, participated in the internet-based survey. Retiree Confidence in their ACA UnderstandingWhile virtually all middle-income retirees have heard of ACA, half are still not confident that they understand how ACA affects them personally. That is why even before the government shut down, the survey found that retirees were asking for less political rhetoric about ACA (88%) and more unbiased information on how the law will affect them personally (84%). Lack of confidence in understanding ACA is even more pronounced among women retirees. Three times as many women do not feel confident in their understanding of ACA as compared to those who feel they have a good understanding of how the law will impact them (56% to 17% respectively). Among the least understood individual provisions of ACA are two that may significantly impact retirees. One in six retirees are not familiar with the fact that ACA caps health insurance premiums for older people relative to rates for younger people (18%) or that it will close the Medicare Part D prescription drug donut hole (18%).
