On March 2, 2012, CMS published a notice inviting additional independent accreditation organizations to submit applications to participate in the advanced diagnostic imaging (ADI) supplier accreditation program as a designated accreditation organization. Selected organizations will be eligible to accredit suppliers furnishing the technical component of one or more categories of ADI services (magnetic resonance imaging, computed tomography, and nuclear medicine imaging such as positron emission tomography). Applications are due May 1, 2012.  To date, CMS has approved three national accreditation organizations to accredit suppliers seeking to furnish the technical component of ADI:  the American College of Radiology, the Intersocietal Accreditation Commission and The Joint Commission.
