That's kind of answered by some of the other doctors in the article: "Michael McGinnis, a New Jersey pathologist who was the third highest paid in the Medicare data, said that payments made to multiple doctors may be recorded under just one in the Medicare data released, making that person look like they were receiving a suspect amount of money. Provider Codes "McGinnis’s provider code was used for about 27 doctors at Plus Diagnostics in Union, New Jersey, where he is the medical director, he said in a telephone interview today. "'I don’t really work directly at the facility, I’m doing administrative work,' McGinnis said, 'I’m not offended by it, but it’ll need to be interpreted correctly so the wrong ideas and wrong statements won’t be made.' "Franklin Cockerill, listed as the fourth-highest paid physician listed within the Medicare data, is in a similar situation, said Bryan Anderson, a spokesman for the Mayo Clinic where Cockerill is employed as chair of the Departmenet of Laboratory Medicine and Pathology. "Cockerill’s 'name is listed as the billing physician for claims submitted for payment under the clinical lab fee schedule,' Anderson said. While he clinic’s labs performed more than 23 million lab tests in 2013, Cockerill is a salaried physician who doesn’t receive Medicare payments." Course, that just raises the question of why Medicare allows for A to bill medicare for a procedure under B's name. I'd think there'd be a way to have separate code for doctors in the same practice.
