DentaQuest FHIR Patient Access API
FHIR R4 (4.0.1) read-only Patient Access API from DentaQuest, the Sun Life U.S. dental company, published under the CMS Interoperability and Patient Access Final Rule (CMS-9115-F). Third-party applications authorize a member with SMART App Launch 1.0.0 (authorization code + PKCE S256, scopes patient/*.read, launch/patient, offline_access, openid, fhirUser) against an Okta CIAM authorization server, then read that member's Patient, Coverage, Organization, Practitioner and RelatedPerson resources, including _history and version reads. Conforms to HL7 US Core (3.1.1, 6.1.0 and 7.0.0-ballot instantiated in the CapabilityStatement). Errors return a FHIR OperationOutcome. The same API is served for the Delta Dental of Massachusetts brand.
