Summary
The CMS Regional Offices (RO) assign CCNs. No other entity has the authority to assign a CCN. • CMS learned that ESRD Networks have issued numbers denoted as “Temporary CCNs” to non-certified ESRD facilities. These are not valid numbers. The temporary numbers were issued to enable the non-certified facilities to enter patient data into the CROWNWeb (CW) data collection system. • CMS instructed the Networks to discontinue issuing these numbers and discontinue entering data into CW using temporary CCNs.
