It belongs to category O88 (obstetric embolism), block O85-O92 (complications predominantly related to the puerperium) and chapter 15 (pregnancy, childbirth and the puerperium). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: O88.21 (pregnancy), O88.22 (childbirth) and O88.23 (puerperium).
