CMS Pub. 100-04, ch. 24, § 50.4.1
CEDI Claim Numbering
CEDI will assign the CCN to accepted ASC X12 and NCPDP claims utilizing the DME
MACs defined range of CCNs. The CCNs are reported back to the Trading Partner on
the front end reports and response files. On the 837 flat file, the CCN will be populated
in the 2300 loop REF segment for that claim where REF01 = +CN. For NCPDP, the
CCN will be populated in the Transaction Header Segment in positions 117-130.
If the number of accepted claims for a given DME MAC exceeds their defined threshold,
CEDI will hold the claims in excess of the threshold to be delivered the next business day
using the next business day’s range of CCNs. Claims held will have the date of receipt
when the CEDI received the claim.
