NCDs are national policy granting, limiting or excluding Medicare coverage for a specific medical item or service. These are developed and published by CMS and apply to all states. NCDs are made through an evidence-based process, with opportunities for public participation. In rare instances, if there is contradicting information in the NCD and LCD, the NCD overrides the LCD.
