The Federal program we know as Medicare, became a reality on 30 July 1965, when it was signed into law. But, the first patients could not sign up for benefits until 1 July 1966. And, by 1979, the American Medical Association managed to get a ruling that the moneys paid to doctors under the program could not be revealed to the public. The reasoning (sic) was that this was an invasion of the physician’s privacy.
