About O46.02

O46.02 is the ICD-10-CM diagnosis code for antepartum hemorrhage with disseminated intravascular coagulation. It belongs to category O46 (antepartum hemorrhage, not elsewhere classified), block O30-O48 (maternal care related to the fetus and amniotic cavity and possible delivery problems) 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 O46.0 (antepartum hemorrhage with coagulation defect), O46.02 is specifically for antepartum hemorrhage with disseminated intravascular coagulation. Related codes cover unspecified (O46.00), afibrinogenemia (O46.01) and other coagulation defect (O46.09).

To report this condition, pick the subcode that matches the documentation: O46.021 (first trimester), O46.022 (second trimester), O46.023 (third trimester) and O46.029 (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.
