About O88.31

O88.31 is the ICD-10-CM diagnosis code for pyemic and septic embolism in pregnancy. 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 4 subcodes must be used instead.

Within O88.3 (obstetric pyemic and septic embolism), O88.31 is specifically for pyemic and septic embolism in pregnancy. Related codes cover childbirth (O88.32) and the puerperium (O88.33).

To report this condition, pick the subcode that matches the documentation: O88.311 (first trimester), O88.312 (second trimester), O88.313 (third trimester) and O88.319 (unspecified trimester).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
