CMS Pub. 100-04, ch. 24, § 50.3.1
Claim Numbering
The CCEM will assign a claim control number to each accepted claim. An accepted
claim is a unit of work, 2300 loop followed by a 2400 loop, as described in the ASC X12
837 claim TR3 that has passed all translator syntax/semantic and CCEM Medicare
business edits and has been assigned a claim control number. The assigned claim control
number will be reported back to the submitter via the ASC X12 277CA claim
acknowledgment. This will provide the submitter with the claim control number earlier
in the adjudication process, thus enabling the submitter to perform more specific claim
status inquiries on individual claims instead of entire submissions via standard HIPAA
adopted transactions or via traditional IVR/ARU (Interactive Voice Response/Automated
Response Unit methods.

Unofficial copy of government-published law, reproduced from official sources with full provenance. Not an official publication; verify against official sources before relying on it in a filing. Records in the 'guidance' corpus, and only that corpus, are sub-regulatory (interpretive guidelines, survey procedures) and are not binding law. Validity bounds follow each jurisdiction's declared temporalBasis.
