CMS Pub. 100-04, ch. 27, § 20.3.3.5
Disposition Code 54 (Matched to Cross-referenced HICN)
The Host provides the MAC with disposition code 54 and Trailer 08 with error code 5052
when it discovers a cross-reference number in its own files for the name or number the
MAC submitted. Disposition Code 54 applies only to A/B MAC (B) or DME MAC-
submitted claims. The possible number and the new full name is returned to the MAC on
Trailers 1 and 10.
• The A/B MAC or DME MAC investigates the information provided and corrects
the information on the claim and resends it.
• If the MAC continues to receive a code 54, it contacts the Host through locally
established procedures.

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.
