The Centers for Medicare and Medicaid Services (CMS) awards geographical jurisdictions to private health care insurers called Medicare Administrative Contractors (MACs), to develop LCDs and process claims. National coverage determinations (NCDs) supersede LCDs, but LCDs expand on coverage policies for each jurisdiction. Coverage policies may vary, including information regarding appropriate coding, credentialing, diagnostic testing, and treatment.
