The Data Element Library (DEL) is a centralized resource for CMS's required assessment instrument data elements (e.g. questions and responses), and their associated mappings to nationally accepted health information technology (IT) standards.

The DEL is the centralized resource for CMS patient assessment instrument data elements. The DERep is a centralized resource of all the data elements and definitions associated with eCQMs used in CMS quality reporting programs by eligible hospitals, critical access hospitals, providers, and clinicians.

In the context of the CMS Data Element Library, data elements are discrete questions and responses that are found in the patient/resident assessment instruments that providers use to submit data to CMS.

No- the DEL is a repository of CMS assessment data elements (questions and responses). It does not affect provider data submission processes. Providers and vendors must still follow the submission specifications required for submitting data to CMS electronically.

As CMS assessment content changes, the Data Element Library will be updated with the most current information.

You can learn more about the Data Element Library by:

Subscribing to the CMS DEL ListServ for updates and learning opportunities;

Reviewing the DEL User Guide, which can be found on the DEL Help/Resources page.

For other questions or assistance using the DEL, please contact the QualityNet Help Desk at 866-288-8912 or send an email to qnetsupport@hcqis.org. Please note the hours of operation for the QualityNet Help Desk are 7am to 7pm CST.

There are no requirements to use the DEL contents. However, CMS assessment stakeholders may use the DEL resource to integrate CMS assessment content into their electronic health records (EHRs) and utilize mapped health IT standards to support interoperable health information exchange. In addition, DEL users could save time and resources by having CMS assessment information in one centralized database, rather than having to search for assessment content across multiple data sources.

The Data Element Library contains no patient health data. The DEL only contains CMS assessment data elements (questions and responses) and their attributes, including how the data elements are linked to nationally accepted Health Information Technology (IT) standards.

The DEL is a public resource for use by providers, vendors, researchers, and the general public. End users will be able to search and obtain reports on CMS assessment contents, including questions, response options, relevant details, and related health IT standards, in one location.
