Centralized Data Repository

The Centralized Data Repository (CDR) provides access to centralized claims, provider, and beneficiary data within a secure HCQIS cloud environment. The CDR increases the accessibility, security, quality, and timeliness of data. There is data ingestion from source systems, less transformations, and better quality data all around. There is a reduction in data duplication and data conflict since all CCSQ/HCQIS users use the same data from the same source. This page identifies the data sources used by or available on the CDR.


CDR Data Catalog

This page lists the current schemas available on the CDR. All data will more closely reflect the source system.
