What is a CCN?
A CMS Certification Number (CCN), is the facility’s six digit identification number and is linked to its Medicare provider agreement. Dialysis Facilities that participate in the Medicare program are required not only to satisfactorily complete the Medicare enrollment application, but also to be certified as meeting the Medicare and State health and safety standards. The CCN number used to be called the “provider number,” but with the advent of the statutorily mandated National Provider Identifier (NPI) number for claims processing, the CCN now plays a different role within the Medicare program.

Each state begins with a two digit identifier:
CT- 07XXXX
ME- 20XXXX
MA- 22XXXX
NH- 30XXXX
RI- 41XXXX
VT- 47XXXX

The CCN is used for CMS certification, and the ESRD Network uses the CCN as a unique identifier for Network projects and reporting- it is very important for you to know your Facility CCN. In addition to correspondence with the Network, and in Network projects and CROWNWeb, you will see your facility’s CCN number on the QIP Performance Score Report that is posted at your facility, as well as in data.medicare.gov public data sets.
