O45.02Premature separation of placenta with disseminated intravascular coagulation

O45.02 is the ICD-10-CM diagnosis code for premature separation of placenta with disseminated intravascular coagulation. It belongs to category O45 (premature separation of placenta [abruptio placentae]), 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 O45.0 (premature separation of placenta with coagulation defect), O45.02 is specifically for premature separation of placenta with disseminated intravascular coagulation. Related codes cover unspecified (O45.00), afibrinogenemia (O45.01) and other coagulation defect (O45.09).

To report this condition, pick the subcode that matches the documentation: O45.021 (first trimester), O45.022 (second trimester), O45.023 (third trimester) and O45.029 (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.
