It's been years since I have worked in this space, but, at the time, my group was charged with finding fraud committed by the providers and beneficiaries.<p>It was interesting work: we had data tapes shipped from CMS to us, we loaded the data into a Sybase database, and then used an analysis tool (which I can't recall the name of) to look for patterns of fraud - again, this was what now seems like a lifetime ago.<p>Is anyone currently working detecting Medicare and Medicaid fraud?
