Researchers have found that Medicare payments for non-invasive medical imaging are now higher to non-radiologists than to radiologists. Researchers have found that Medicare payments for non-invasive medical imaging, including magnetic resonance imaging ( MRI ) and computed tomography ( CT ) scans, are now higher to non-radiologists than to radiologists, according to a study in the January issue of the Journal of the American College of Radiology.

"Radiologists have always been considered the physicians who "control" non-invasive diagnostic imaging (NDI) and are primarily responsible for its growth. Yet non-radiologists have become increasingly aggressive in their performance and interpretation of imaging," said David C. Levin, MD, lead author of the study.

Researchers looked at Medicare Part B files covering all fee-for-service physician payments for 1998 to 2008. They selected all codes for discretionary NDI. "We found that the growth in fee-for-service payments to non-radiologists for NDI was considerably more rapid than the growth for radiologists between 1998 and 2006," said Levin.

In 1998, overall Part B payments to radiologists for discretionary NDI were $2.563 billion, compared with $2.020 billion to non-radiologists. In 2008, non-radiologists received $4.807 billion for discretionary NDI, and radiologists received $4.648 billion.

"Our data reveal the somewhat surprising finding that non-radiologist physicians are now paid more for NDI by Medicare than radiologists. This has come about because of more rapid growth in fee-for-service payments to non-radiologists between 1998 and 2006, followed by steeper losses among radiologists after implementation of the DRA in 2007," he said.

"Because most imaging by non-radiologists is self-referred, whereas radiologists generally do not have the opportunity to self-refer, this should be of interest and concern to policy makers and payers," said Levin.
