§484.45(c) Standard: Transmittal of OASIS data
An HHA must—
(1) For all completed assessments, transmit OASIS data in a format that meets the
requirements of paragraph (d) of this section.
Interpretive Guidelines §484.45(c)(1)
Successful transmission of OASIS data is verified through validation and feedback
reports from iQIES. Although not required by the regulation, it is recommended that the
HHA keep copies of the electronic validation records, that indicate transmission was
successful, for twelve months, or until the next set of reports are available. The validation
reports may be needed as evidence if the HHA receives a denial from the Medicare
Administrative Contractor (MAC) for missing OASIS assessments.

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.
