7. Some Interesting Findings According to the Medicare Payment Advisory Commission, only 9.3% of those covered by Medicare in 2000 were covered solely by Medicare. According to the US Census Bureau, people with access to Indian Health Service have been counted as uninsured since 1997. When Census Bureau survey respondents were asked to verify that the lack of a positive indication of a form of coverage really meant that they were uninsured, the result was a “reduction” of “uninsured” from 41.9 million to 38.4 million.
