Through the Lewin Group and its subcontractors, CMS has announced a 30-day comment period lasting through Dec. 14, 2008, regarding a draft set of measures intended to improve efficiency in the provision of outpatient imaging services. According to CMS, the proposals are in response to the growth in volume of imaging services, which grew by almost 10 percent annually from 1999 through 2003. Currently, there are four proposed measures: (1) SPECT MPI and Stress Echocardiography for Preoperative Evaluation for Low-Risk Non-Cardiac Surgery Risk Assessment; (2) Use of Stress Echocardiography or SPECT MPI Post-Revascularization Coronary Artery Bypass Graft; (3) Use of Computed Tomography in Emergency Department for Headache; and (4) Simultaneous Use of Brain Computed Tomography and Sinus Computed Tomography. You can find more detailed information and an abstract of each measure here.
