Full CMS Certification Number for Provider

SAS Name

This variable is the extended CMS Certification Number (CCN). This extended field is designed to allow for the identification of multiple campus hospitals. For multicampus hospitals, all campuses contain the same first 6-digit CCN (reference PRVDR_NUM variable in this data file), but positions 7–13 may be used to distinguish between campuses (ex. 01, 02, 001, 002, A, etc.) In the future positions 7–13 may have other uses.


NCH will continue to map the positions 1–6 of the provider number to the provider number (PRVDR_NUM) field. This field is not populated prior to 2021.
