LegalAuthenticator (CDA Class) - Clinical Document Architecture v2.0.1-sd-202510-matchbox-patch

Logical Model: LegalAuthenticator (CDA Class)

Official URL:http://hl7.org/cda/stds/core/StructureDefinition/LegalAuthenticator Version:2.0.1-sd-202510-matchbox-patch
Active as of 2025-10-29 Computable Name:LegalAuthenticator

Represents a participant who has legally authenticated the document. The CDA is a standard that specifies the structure of exchanged clinical documents. In the case where a local document is transformed into a CDA document for exchange, authentication occurs on the local document, and that fact is reflected in the exchanged CDA document. A CDA document can reflect the unauthenticated, authenticated, or legally authenticated state. The unauthenticated state exists when no authentication information has been recorded (i.e., it is the absence of being either authenticated or legally authenticated). While electronic signatures are not captured in a CDA document, both authentication and legal authentication require that a document has been signed manually or electronically by the responsible individual. A legalAuthenticator has a required legalAuthenticator.time indicating the time of authentication, and a required legalAuthenticator.signatureCode, indicating that a signature has been obtained and is on file.
