Abstract: Embodiments of the present disclosure relate to systems, methods, and user interfaces for providing CUI hinting for health care value set curation. Initially, a code corresponding to a CUI is received. The state of each CUI for a value set is established based on the current included and excluded codes corresponding to each CUI. Codes may have more than one CUI assigned, but the hinting process may only use codes with a single assigned CUI. Based on the state of each CUI for the value set, a hint is provided for the code. The hint is based on the state of the CUI and may prompt a user to include, exclude, or review the code for the particular value set or inform the user that the code is inherently ambiguous with respect to the particular value set. The CUI hinting provides higher quality, consistency, and efficiency during the curation process.
