The Provider Registry (PR) is a foundational component of the Electronic Health Record (EHR) which provides a trusted and centralized source of regulated health service provider information to authorized consumers. Health Service Provider Identifiers (HSPID) within the PR enable unique identification of individual health care providers across the systems participating in the EHR. Demographic and licensing information for all providers is stored within the PR for validation and/or retrieval by source and consumer systems and organizations.
This Guide relates to the messaging standards used to provide and maintain the information in the Provider Registry as well as those used to access it from consumer applications.
