On November 27, 2012, CMS posted a list of medical items and services that it might consider for future Medicare coverage review, including potential NCD topics. The list is based on public response to CMS’s previous request for feedback on items and services that may be inappropriately used (i.e., underused, overused, or misused), may provide minimal benefit, or might improve health outcomes but are not currently covered by Medicare. While most of the items listed were suggested by the public, CMS also identifies three internally-generated topics: intraaortic balloon pumps and paracorporeal ventricular assist devices, lap-band surgery for obesity, and kyphoplasty. CMS notes that the internally-generated topics are based on medical literature review and horizon scans, Medicare claims experience, and interactions with the stakeholder community.
