USADA traced more than $1 million in payments from Armstrong to Ferrari from 1996 to 2006 and the report details how the physician told Armstrong and other riders to dope with EPO and blood transfusions.
In July, USADA banned Ferrari for life.
Calls to Ferrari's home by The Associated Press on Tuesday were unanswered, and the physician's lawyer did not immediately return a message.
