About O88

O88 is the ICD-10-CM diagnosis code for obstetric embolism. It belongs to 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 5 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: O88.0 (embolism), O88.1 (embolism), O88.2 (thromboembolism), O88.3 (embolism) and O88.8 (embolism).

Don't report O88 together with the conditions in its Excludes1 note: embolism complicating abortion NOS (O03.2), embolism complicating ectopic or molar pregnancy (O08.2), embolism complicating failed attempted abortion (O07.2), embolism complicating induced abortion (O04.7) and 1 more.

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