Medicare’s prescription-drug program is a common target for fraud, it turns out. A 2013 investigation by ProPublica and NPR focused on the program. Reporters looked into the case of Ernest Bagner, a psychiatrist in whose name millions of dollars of drugs were prescribed. Bagner claimed his identity had been stolen and used to acquire the drugs, and while authorities weren’t convinced that his story was true, Medicare also never restricted his ability to prescribe drugs through the program.
