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:&#x2F;&#x2F;www.pulitzer.org&#x2F;winners&#x2F;7226" rel="nofollow">http:&#x2F;&#x2F;www.pulitzer.org&#x2F;winners&#x2F;7226</a><p>The work they published to win the award was great, but he&#x27;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:&#x2F;&#x2F;www.cms.gov&#x2F;research-statistics-data-and-systems&#x2F;statistics-trends-and-reports&#x2F;medicare-provider-charge-data&#x2F;physician-and-other-supplier.html" rel="nofollow">https:&#x2F;&#x2F;www.cms.gov&#x2F;research-statistics-data-and-systems&#x2F;sta...</a><p>If you&#x27;re interested in what the data contains, it&#x27;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:&#x2F;&#x2F;2015.padjo.org&#x2F;tutorials&#x2F;sql-walks&#x2F;exploring-wsj-medicare-investigation-with-sql&#x2F;" rel="nofollow">http:&#x2F;&#x2F;2015.padjo.org&#x2F;tutorials&#x2F;sql-walks&#x2F;exploring-wsj-medi...</a><p>I&#x27;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.
