New data released Wednesday by the Centers for Medicare and Medicaid show some doctors know how to bill the system. One cardiologist in Florida, for example, earned $18 million in Medicare payments in 2012, according to a report by the Washington Post.

For the first time in more than two decades the public can identify how much physicians earn through Medicaid reimbursements. The release follows a ruling last year in federal court in Florida that overturned a 1979 injunction won by the American Medical Associate that made physician-level data secret.

Rebecca Callis, a rheumatologist in Salem, received $2.7 million in Medicare reimbursements in 2012 – the top individual payee in the state and one of 15 physicians bringing in more than $1 million from Medicare, according to a WW analysis.

Other top earners in Oregon include ophthalmologist Jeffrey Rinkoff of Medford and oncologist Barry Blyton of Springfield, who both brought in $2.2 million in 2012. Ophthalmologists Michael Lee and Mark Peters, were Portland's top earners, each receiving nearly $1.3 million in Medicare payments.

Here's how one rheumatologist explained his high revenue to the Washington Post:

Gerald Ho, 50,

a rheumatologist who runs three offices in the Los Angeles area, said he had

been “sort of dreading” the release of the Medicare payment data. Ho received

nearly $5.4 million in reimbursements in 2012. Of that, he said, probably about

$5 million covered the cost of genetically-engineered drugs to treat patients

with rheumatoid arthritis. He also has to pay a staff of 40.

“People are

going to see these numbers and people aren’t going to understand,” he said. “I

am not pocketing $5.3 million. To tell you the truth, I know there’s been lot

of Medicare fraud, and I understand the government wants to provide a measure

of transparency. But when they throw out numbers like this without any context,

it’s going to be misconstrued by the public.”
