Section 220.2 of the National Coverage Determination (NCD) Manual, effective since 1985, established coverage of MRI for a number of uses. The policy has been expanded over the years; CMS last reconsidered this NCD in 2011. Aside from an exception for MRI furnished in approved clinical studies of implanted pacemakers and implantable cardioverter defibrillators (ICDs) under the Coverage with Evidence Development (CED) paradigm, MRI is generally non-covered when certain patient-specific contraindications are present, including, among others, patients who have implanted cardiac pacemakers. CMS is opening this national coverage analysis to reconsider coverage indications for MRI. This reconsideration is limited to MRI and does not include any coverage determination about magnetic resonance (MR) conditional pacemakers, MR conditional ICDs, or any other pacemaker or ICD. See Medicare’s NCD on Cardiac Pacemakers at 20.8 and Implantable Automatic Defibrillators at 20.4 of the NCD Manual. CMS initiates this national coverage analysis for reconsideration of Section 220.2 of the NCD Manual. The initial 30-day public comment period begins with this posting date, and ends after 30 calendar days.
