The United States Health Information Knowledgebase (USHIK)

The United States Health Information Knowledgebase (USHIK) is a registry and repository of health care-related metadata, specifications, and standards. The CMS Quality Programs portal provides the ability to view, download, and compare eCQM specifications, data elements, value sets, and codes released by CMS and NLM. Each eCQM release package is available in a single file, or can be downloaded as eligible hospital, eligible professional, and individual measure packages. These files are available in PDF, Excel, CSV, HQMF XML, or XML. UHSIK provides the ability for public comments to be received on measures and measure updates under consideration. This knowledgebase is produced by the Agency for Healthcare Research and Quality (AHRQ) in partnership with CMS and NLM.

Note: Viewing and/or downloading proprietary value sets, such as those using AMA copyrighted CPT codes or SNOMED CT codes, from NLM-VSAC or AHRQ-USHIK requires a free Unified Medical Language System® Metathesaurus License (UMLS), (available at https://uts.nlm.nih.gov/license.html). It is expected that any use of value sets is consistent with these licensing requirements and copyright protections.
