Existing Wording: Extension Extension: Sex of patient assigned at birth - Mappings

Mappings for HL7 v2 Mapping (http://hl7.org/v2) - Mapped to HL7 Version 2 PID-8

Mappings for RIM Mapping (http://hl7.org/v3) to "administrativeGender"

Proposed Wording: V2 - to OBX-5 Observation Value.

V3 - Map to "ObservationValue [2.16.840.1.113883.5.1063]"

Comment:

PID-8 is "Administrative Sex" which is not the same as birth sex. "Administrative Sex" is used for administrative purposes such as inpatient bed assignment and billing/claims processing.

Accurate Birth sex is critical for laboratory result reporting and in V2 and V3 should be reported as a clinical observation. PID-8 was originally (up until V2.4) titled "Sex" but the field title was clarified for harmonization when HL7 Version 3 differentiated the concepts of "administrative gender" defined as "The gender of a person used for administrative purposes (as opposed to clinical gender)" thus creating two distinct concepts.

Suggest working with Patient Administration to determine whether it is possible to clarify the definition of V2 PID-8 to include Birth Sex, but since V2 is normative and per ANSI, has to be backward compatible this may not be possible.

Another alternative is to add a new field to the V2 PID segment to capture Birth Sex.
