description | The US Core Encounter Profile inherits from the FHIR [Encounter](https://hl7.org/fhir/R4/encounter.html) resource; refer to it for scope and usage definitions. This profile sets minimum expectations for the Encounter resource to record, search, and fetch basic encounter information for an individual patient. It specifies which core elements, extensions, vocabularies, and value sets **SHALL** be present and constrains how the elements are used. Providing the floor for standards development for specific use cases promotes interoperability and adoption. | The profile establishes the core elements, extensions, vocabularies and value sets for representing deidentified encounters or visit information. | Values Differ
