LOINC LL4129-4 Pregnancy Status (https://loinc.org/LL4129-4/)

LOINC answer list LL4129-4 (for LOINC observation code 82810-3) defines three values: Pregnant, Not pregnant, Unknown. This vocabulary carries those three verbatim and adds `postpartum` as a PublicSchema extension. Note that the FHIR R4 International Patient Summary pregnancy-status pattern uses SNOMED CT codes for the observation value, not the LOINC answer list; implementations that need FHIR IPS conformance should map through SNOMED CT rather than treat this vocabulary as a drop-in.

Values

Code Label Standard code Definition
not_pregnant Not pregnant The person is not currently pregnant.
pregnant Pregnant The person is currently pregnant.
postpartum Postpartum The person has recently given birth and is in the postpartum period. This value is a PublicSchema extension for social protection use; FHIR handles postpartum via a separate observation.
unknown Unknown The pregnancy status is not known or was not ascertained.
