CMS Pub. 100-04, ch. 6, § 110.3
CWF Override Codes
A CWF override code has been developed for A/B MAC (B) or DME MAC use where,
in the course of pursuing a reconsideration, a provider or supplier may bring to the
attention of the A/B MAC (B) a situation where services on a claim have been denied,
but should actually be allowed to be paid through the A/B MAC (B)/DME MAC. At the
A/B MAC (B)/DME MAC’s discretion, to allow that claim to process through CWF to
payment, enter a “2” in the SNF consolidated billing override field.

The link goes to the issuing authority’s own document — the one we read to produce this record. Where a source publishes whole titles rather than sections, your browser may need a moment to jump to the provision.
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.
