O45.0Premature separation of placenta with coagulation defect

O45.0 is the ICD-10-CM diagnosis code for premature separation of placenta with coagulation defect. 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 (premature separation of placenta [abruptio placentae]), O45.0 is specifically for premature separation of placenta with coagulation defect. Related codes cover other premature separation of placenta (O45.8) and premature separation of placenta, unspecified (O45.9).

To report this condition, pick the subcode that matches the documentation: O45.00 (unspecified), O45.01 (afibrinogenemia), O45.02 (coagulation) and O45.09 (defect).

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