FHIR Security Labels represents the HL7 FHIR Security Labels mechanism within the MyHealth@MyHands. FHIR Security Labels are coded metadata values applied to FHIR resources that enforce access policies by marking health data with confidentiality classifications, clinical sensitivity categories, and handling instructions. They implement the Maccess.policy governance domain at the individual FHIR resource level, enabling fine-grained, attribute-level access control within MyHealth@EU exchanges.
