CMS Pub. 100-04, ch. 37, § 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.
