Use of CMS Certification Numbers (CCNs) After National

1.4 - Use of CMS Certification Numbers (CCNs) After National Provider Identifiers (NPIs) Are Fully Implemented (Rev. 11396, Issued:05-04-2022, Effective:10-01-2022, Implementation:10-03-2022) While equivalent to Medicare claims in overall appearance and the nature of the services rendered, VA claims contain unique elements to ensure that they are processed appropriately and apart from Medicare claims, and in particular that payment is not made. Among these characteristics are a demo code and provider numbers which are unique to this project. CMS has determined that it is in its best interests to have the VA continue to submit the MRA project transactions with its CMS Certification Number (CCN) instead of NPIs. In addition, if the VA providers begin using an NPI for other purposes, Medicare- equivalent remittance advice claims must be submitted to CMS with a VA CMS Certification Number (CCN) as the provider identifier. The demo number (31) will be assigned based on the CCN submitted and by the A/B MAC (A) or (B) number.
