List of CMS Certification Numbers (facility numbers) for the practice.
Comments
The first six digits of each CMS Certification Number (CCN) are the facility number; additional digits (i.e., positions 7–13) may be used to distinguish between campuses for multiple campus hospitals. This field could be missing or have one or more CCNs, separated by a comma.
Note that if attempting to join to Medicare claims files in the CCW, the 6-digit CCN is called the provider number (PRVDR_NUM).
