Health savings accounts (HSAs), which were created by the Medicare legislation recently passed by Congress, allow individuals to save for their future health care needs on a tax-preferred basis. HSAs are available to anyone who purchases high-deductible health insurance, and employers may also make tax-free contributions. Will HSAs become an attractive alternative to traditional health insurance for a significant number of people? Will they offer an affordable way for the uninsured to gain health coverage? Will HSAs fragment or strengthen employer-sponsored insurance? Will HSAs make people more cost-conscious in their use of health services? A panel of experts will discuss the potential impact of these accounts on the American health care system.
