PWK Workflow
The PWK segment is the “electronic staple” which connects paper documentation to an
electronic claim. Claims are submitted electronically with the PWK segment populated.
The additional documentation is then submitted to the A/B MACs, DME MACs or CEDI
at the same time or within close proximity of the electronic claim. If needed, the A/B
MACs, DME MACs or CEDI will use the additional documentation in their adjudication
of the claim. If the claim does not require additional documentation, the claim will be
adjudicated without reviewing the additional documentation. If the additional
documentation is not received or provides no value, the claim will be handled as it
normally would have if the PWK data not been submitted.

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.
