FWIW Carreyou and his WSJ colleagues were awarded the Pulitzer for Investigative Reporting last year for a project on Medicare fraud:<p><a href="http://www.pulitzer.org/winners/7226" rel="nofollow">http://www.pulitzer.org/winners/7226</a><p>The work they published to win the award was great, but he'd been fighting that fight for many years...and his dogged pursuit led to the CMS agreeing to publish the reimubrsement data in full, for the first time ever:<p><a href="https://www.cms.gov/research-statistics-data-and-systems/statistics-trends-and-reports/medicare-provider-charge-data/physician-and-other-supplier.html" rel="nofollow">https://www.cms.gov/research-statistics-data-and-systems/sta...</a><p>If you're interested in what the data contains, it's only a couple of GB as a flat table, but contains Medicare reimbursements for every doctor, for every type of reimbursed procedure, which allows for a lot of interesting analysis about healthcare in general...I wrote up a walkthrough that explains how Carreyou arrived at his numbers for the lead story in the investigation: <a href="http://2015.padjo.org/tutorials/sql-walks/exploring-wsj-medicare-investigation-with-sql/" rel="nofollow">http://2015.padjo.org/tutorials/sql-walks/exploring-wsj-medi...</a><p>I've never met him or asked him how he did his work...but it underscores what a great thing he and the WSJ managed to accomplish: producing an important investigative story and pushing for the release of the data so that anyone else could reproduce it.
