In managed care costs are buried within "premiums" and since premium calculations are treated as trade secrets, it is very difficult to interpret them. Without cost information it is impossible to be a prudent buyer. Often there are excess payments made and it takes skill and tools to recover them. Also preventive care treatments take many years to bear fruit and so there is no easy way to ensure that progress is being made. CareMaps is a patented tool we developed, that helps assess health of populations, changes in them and treatment costs. It is able to make 12 month forecasts of numbers of people developing various diseases and their treatment costs with less than 5% error. It detects anomalous costs in various regions that are precursors to fraud and abuse. In one state over $600 million was recovered after a CareMaps analysis initially discovered a $250 million over payment in one year.
