Medicare. Can its benefits be sustained as cost of coverage grows?

By many measures Medicare is one of the most successful government programs ever instituted, and its benefit to the health of older citizens is unquestioned. Yet it is not without chronic problems and challenges, including the cost of administering the program, limited insurance coverage for certain services and conditions, lack of standardization, and fraud. Moreover, new challenges arise as societal circumstances change and political demands fluctuate. Chief among the concerns are the imminent influx of baby boomers into the system and the debate over expanding the limited scope of Medicare coverage.
