Information about Doctors
One major source of medical information is the American Medical Association, which represents 40% of an estimated 700,000 doctors nationwide but maintains a "master file" of information on most doctors practicing in the USA.
The organization nets more than $40 million in fees each year, about half from hospitals seeking to verify doctors' credentials and the rest from nearly a dozen firms that repackage the information and sell it to their clients. About 22,000 doctors have opted out of the AMA program, says spokesman Robert Mills.
I’m not sure why the AMA gets to classify itself as a nonprofit organization. Shouldn’t it be paying taxes just like any other business
