Abbreviated process for making changes to the coding component of the negotiated laboratory National Coverage Determinations (NCDs). The process is used for adjusting the list of covered or noncovered diagnostic codes and coding guidance in the NCDs when there is a question regarding whether the code flows from the narrative indications in the NCD. A tracking sheet is posted after opening a CAL, and a 30-day public comment period follows. A decision memorandum that announces and explains the decision is posted after the comment period. Changes are adopted in the next available quarterly update of the laboratory edit module.
