Several things have excess costs amounting to 5-10% of the total. The whole reason it's so hard to fix this problem is that there isn't one source of excess or unnecessary expenses. Insurance? "Well, sure, but that's only 5-10% of the cost". Other admin? "Well sure, but that's only 5-10% of the cost". Too-high doctor salaries? "Well sure..." and so on. Taking the per-capita admin costs from ~$1600 to a closer-to-normal ~$600 is a major win. It is not negligible. Further, all the data have shown so far is that admin costs aren't under 15% of the total. More categories of admin costs (any from health care providers that aren't hospitals, notably) still lurk somewhere in that inpatient/outpatient care block.
