In April, Medicare spewed out some schismatic physician-payment numbers. The blast of decontextualized data said that one ophthalmologist received $12 million in payments. Another 4,000 physicians took in over $1 million in 2012 just from Medicare Part B. The New York Times' number generator let readers type in a doctor's name and get a dollar amount. In a lot of cases, physicians came off looking seriously flush with cash. Those numbers and the accompanying "Go to medical school, you can make more than Lebron" implications were misleading in that they represent revenue, not profit. Like so many doctors, knowing there's a difference between revenue and profit is around the upper limit of my financial acumen.
