Project Summary

The FHIR Implementation Guide for the Human Services Data Specification (HSDS) describes the architectural considerations for accessing data from directories of social services. The Guide aligns the FHIR profiles from the DaVinci Payer Data Exchange (PDEX) Plan-Net Directory that enable health plans to publish healthcare provider directory information to members and patients via FHIR APIs, with the Human Services Data Standard (HSDS), an industry standard for service directory data exchange that represents information about human service agencies, the services they provide, and the locations where they are offered.
