Descriptions

matchReason — HL7 International OID Registry

Code system of concepts identifying what search components (e.g., name, birthdate, social security number) of the record returned matched the original query where the responding system does not assign numeric match weights or confidence levels. It provides a method for passing a descriptive indication of the reason a particular record was found. Used in HL7 Version 2.x messaging in the Query Response Instance (QRI) segment.
