CMS is hosting a meeting January 31, 2011 to receive comments regarding the development of additional imaging efficiency measures for use in the Medicare Hospital Outpatient Quality Data Reporting Program. Potential topics for discussion include: imaging procedures that would be appropriate candidates for imaging efficiency measures (in addition to current imaging efficiency measures); data sources appropriate for imaging efficiency measures; other potential settings for imaging efficiency measures besides outpatient hospitals; and development of imaging measures based on diagnosis/condition rather than specific procedures. Measure developers, hospitals, medical specialty societies, medical professionals, and other interested stakeholders are invited to participate either in person or via teleconference. Registration opens January 7, 2011, and written comments will be accepted until February 10, 2011.
