Though millions of Americans have gotten health coverage under the Patient Protection and Affordable Care Act, a new report finds many more either are still unaware of their options or are simply not interested.

According to analysis from the Urban Institute and the Robert Wood Johnson Foundation, about 60 percent of the remaining uninsured population cite cost as the reason why they do not have health coverage. But another 20 percent simply say they don't want it.

Awareness of the law — and its coverage options — still is problematic, the brief, which examined the remaining uninsured, found. It showed that 58.5 percent of the remaining uninsured have heard about the exchanges, but less than 40 percent know about the availability of subsidies to help make insurance premiums more affordable.
