A Senate panel says some of the nation’s largest insurance companies have begun manipulating their accounting practices to avoid following the new healthcare reform laws. In a new report, the Senate Committee on Commerce, Science and Transportation says insurers are counting administrative costs as medical costs to avoid requirements on how every premium dollar is spent. The report cites the insurance giant WellPoint as having “'reclassified' more than half a billion dollars of administrative expenses as medical expenses.” The news comes as the insurance giant UnitedHealth Group has announced chief executive Stephen Hemsley took home almost $100 million in compensation from exercising stock options last year.
