LCDs are created by the MAC assigned by CMS to each jurisdiction. National Government Services is the MAC for Jurisdiction 6 – Illinois, Minnesota and Wisconsin, and Jurisdiction K – Maine, New Hampshire, Vermont, Massachusetts, Rhode Island, Connecticut and New York. The MACs LCDs are applicable only in the states they support, therefore it is imperative to research LCDs through your assigned MAC website as they can differ from one jurisdiction to another. NCDs are created by CMS and apply nationally, to all jurisdictions. If CMS has created an NCD, the MAC will not create an LCD on the same topic.
