Alaska and Massachusetts don't tend to have much in common when it comes to health care, but they do have this: The two spend vastly more per capita on health care than any other state in the country. That's among the findings from a new, decade-long review of state healthcare spending published Wednesday by the Center for Medicare and Medicaid Services. It found huge geographic variations that can't be explained away by any one factor. Health care spending in the United States ranges from a high of $9,278 per person in Massachusetts to $5,031 in Utah. On average, it hovers at $6,815 per person, a $1,300 increase from just over a decade ago, in 1998.
