Salem, OR -

A Salem rheumatologist received more money from Medicare in 2012 than any other doctor in Oregon.

Data released last week from the U.S. Centers for Medicare and Medicaid Services show Dr. Rebecca Callis received $2.7 million. She billed for nearly 115,000 services for 547 patients.

Callis told the Statesman Journal in an email that she didn't know why her numbers were so much higher than other rheumatologists but billing is not profit. She says money also goes toward overhead, wages and the cost of expensive therapies for autoimmune disease.
