The value set Binding Parameter Specification (BPS) is generated by the National Library of Medicine (NLM) and is a record of the value set metadata information that defines the code lists specified by current CMS eCQMs. Measure implementers and vendors use the BPS to track versions and other parameters that define the code lists for each eCQM release. Users can access the BPS metadata file for any released set of CMS eCQM value set files through the NLM's Value Set Authority Center Downloadable Resources.
