Medicare Coverage - General Information

Medicare provides coverage for items and services for over 55 million beneficiaries. The vast majority of coverage is provided on a local level and developed by clinicians at the contractors that pay Medicare claims. However, in certain cases, Medicare deems it appropriate to develop a National Coverage Determination (NCD) for an item or service to be applied on a national basis for all Medicare beneficiaries meeting the criteria for coverage. This page provides general information on various parts of that NCD process, resources of both a general and historical nature, and summaries and support documents concerning several miscellaneous NCDs.


People with Medicare, family members, and caregivers should visit, the Official U.S. Government Site for People with Medicare, for the latest information on Medicare enrollment, benefits, and other helpful tools.
