Value set for the timing of pregnancy relative to death, as documented in the Women of Reproductive Age section of the WHO Medical Certificate of Cause of Death (MCCoD), Frame B.

This value set is applicable ONLY when:

  • The deceased was female aged 15–49 years at time of death, AND
  • The question "Was the deceased pregnant within past year?" is answered Yes

These timing categories are consistent with WHO maternal death surveillance definitions and ICD-11 Chapter 18 (Pregnancy, childbirth or the puerperium) coding rules.

Binding strength at profile level: REQUIRED When the pregnancy timing element is present, only these codes are permitted.

Relationship to maternal death classification:

  • "When she died" → Direct or indirect obstetric death (ICD-11 Chapter 18)
  • "Within 42 days" → Late maternal death (WHO definition)
  • "43 days to 1 year" → Late maternal death surveillance window
  • "Exact timing unknown" → Unspecified maternal death timing

Whether pregnancy contributed to death is a separate Yes/No/Unknown element in the MCCoDPregnancyStatus profile and is not covered by this value set.

SNOMED CT cross-reference (informative, not binding):

  • Within 42 days → 59283008 (Death within 42 days of delivery)

ICD-11 cross-reference (informative, not binding):

  • When she died → JA00–JB6Z (Pregnancy, childbirth or the puerperium)
  • Within 42 days → JB60 (maternal death)
  • 43 days to 1 year → JB61.0 (Death during pregnancy more than 42 days)
  • Exact timing unknown → JB6Z (Unspecified obstetric condition)

Guidance for member countries: Countries SHOULD map these codes to their national maternal death surveillance system classifications in their national implementation guide.

Level A few code lists that FHIR defines are hierarchical - each code is assigned a level. In this scheme, some codes are under other codes, and imply that the code they are under also applies
System The source of the definition of the code (when the value set draws in codes defined elsewhere)
Code The code (used as the code in the resource instance)
Display The display (used in the display element of a Coding). If there is no display, implementers should not simply display the code, but map the concept into their application
