From Investigative Reporters and Editors:
"In a superb series on behalf of the taxpayer, The Center for Public Integrity exposed how the medical industry has raised the “risk scores” for elderly patients to overbill the Medicare Advantage program tens of billions of dollars. Despite the challenges of dealing with complex and voluminous government data the Center aptly dissected the shocking shortcomings of a program that was meant to stabilize costs, but instead has allowed the industry to harvest huge sums by saying patients were sicker than they were. The explanation of the risk score system and the analysis of how it is manipulated was particularly lucid."
