11.15.2021 NCQA DAV Data May organizations use NCQA-validated data resulting from Data Aggregator Validation (DAV) as standard supplemental data when reporting HEDIS measures?

Yes. NCQA DAV data may be used as standard supplemental data if the auditor receives a completed current year’s Roadmap Section 5 from the reporting entity using the data. The Roadmap must explain how data from the validated DAV entity is transferred to the reporting entity and what the entity does to the data. The Roadmap is completed by the health plan; no documentation is required from the DAV entity except for the final list of validated ingestion sites and clusters, along with the date they were approved. If the reporting entity processes the validated CCD in any way after receipt, the auditor must validate the file back to the original validated CCD to ensure that no data were changed.
If an NCQA-validated DAV entity includes data from an unvalidated data cluster, the auditor must validate that data, following the nonstandard supplemental data guidelines, before the data can be used for HEDIS reporting. The auditor may not perform PSV on any validated data files.
The NCQA DAV data definition will be included in General Guideline 31 for MY 2022.
