Although the recent spotlight has been on what the federal government will do to rein in the rising numbers of medical imaging procedures, states also are doing their part.
In Maryland, state law requires that only licensed radiologists perform advanced imaging procedures such as CTs, MRIs, or PET scans. Radiologists say that laws like this help decrease the use of inappropriate imaging, which they say is done largely by nonradiologists who use the equipment in their offices.
“We believe Maryland's law is a model that we would like to see in other states,” said Josh Cooper, senior director of government relations at the American College of Radiology, in Reston, Va. Florida has a similar law, but it is not as restrictive as Maryland's, he said.
Another way states are trying to manage the use of imaging equipment is through “certificate of need” laws that require physicians and others setting up imaging facilities to obtain a certificate of need to document that there is a demand in the community for such a facility. Rhode Island has such a law, Mr. Cooper said.
While the radiologists and their college are keen to support state and federal laws that limit imaging utilization, other physicians say the radiologists are just trying to keep the business for themselves.
“The radiology community … claims that growth in imaging is due to 'self-referral' by physicians who own their imaging equipment, and that the quality of images and interpretations by nonradiologists is inferior to those by radiologists,” the Lewin Group, a Falls Church, Va., consulting firm, said in a report for the Coalition for Patient-Centered Imaging, a coalition of medical specialties that wants specialists to be able to perform in-office imaging procedures.
“Our findings suggest that self-referral is not the primary driver of growth in imaging services. Some of the fastest-growing imaging services, such as MRI and CT scans, are primarily done by radiologists.”
State legislatures are seeking fresh approaches to the issue. A bill currently in the California legislature would exempt only radiologists and cardiac rehabilitation physicians from a ban on physician self-referral.
The California Medical Association (CMA) is opposed to the bill, according to spokeswoman Karen Nikos. The group's opposition is based on its self-referral policy, adopted in 1993, which states: “While CMA recognizes that there is nothing inherently wrong when a physician invests in a facility or when a physician refers a patient to a facility in which the physician has an ownership interest, CMA recognizes that serious ethical questions are raised when referrals are made purely for a profit motive.
“CMA has a responsibility to create policy and support legislation that would prevent abusive practices such as overutilization and overcharging.”
