Clinical Value Sets for Electronic Quality Measures

A repository of standardized clinical code lists from the U.S. National Library of Medicine. It provides downloadable access to official value sets for Centers for Medicare & Medicaid Services electronic Clinical Quality Measures (eCQMs). The VSAC is a tool for authoring and accessing public value sets from vocabularies like SNOMED CT and RxNorm.

Use Cases

• Map clinical concepts to standardized SNOMED CT or RxNorm codes for interoperable health data exchange.
• Author or retrieve specific value sets to support the implementation of CMS electronic Clinical Quality Measures (eCQMs).
• Integrate standardized terminologies like LOINC and ICD into clinical information systems using the provided API.

Strengths

• Managed by the authoritative U.S. National Library of Medicine in collaboration with ONC and CMS.
• Aggregates value sets from multiple standard clinical vocabularies, including SNOMED CT, RxNorm, and LOINC.
• Provides access to all official versions of CMS eCQM value sets, ensuring alignment with regulatory requirements.

Limitations

• Data is provided in HTML format, which is not optimal for direct programmatic analysis and requires parsing.
• The repository does not create its own content, so coverage is dependent on external program submissions.
• The specific count of available value sets, rows, or records is not provided in the metadata.
