Some other employers have reduced benefits or simply ceased to sponsor coverage. For retirees 65 years or older, Medicare is typically the primary source of health insurance coverage. Concluding Observations

Premium increases and forecasts for a potential economic slowdown could pose concerns for many employers and may make employer- sponsored benefits vulnerable to further erosion. In the longer term, these factors, coupled with the potential for Medicare reforms and an increasing number of aging baby boomers, may produce even more uncertainty and cost pressures for employers. Consequently, as the number of retirees without employer-based coverage increases, retirees, particularly those in poorer health, may encounter difficulty finding affordable alternative health coverage.
What GAO Found

In 1999, nearly 10 million retired people aged 55 or older relied on employer-sponsored health insurance as either their primary source of coverage or as a supplement to their Medicare coverage. Some of these persons are concerned about the continued availability of employer-sponsored coverage. Premium increases and forecasts for a potential economic slowdown could further erode employer-sponsored benefits. In the long term, these factors, coupled with the potential for Medicare reforms and the rising number of aging baby boomers, may produce even more uncertainty and cost pressures for employers. Consequently, as an increasing number of retirees lack employer-based coverage, those in poorer health may have difficulty finding affordable alternative health coverage.
