Transmission Requirements
A/B MACs, DME MACs, and CEDI may continue to operate automated response unit
(ARU) capability for providers to request and receive claim status information. ARUs
are not considered EDI and are not affected by the HIPAA requirements. Nor do they
impact response time requirements for the standard transactions implemented under
HIPAA.

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.
