About O45.8

O45.8 is the ICD-10-CM diagnosis code for other premature separation of placenta. 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 1 subcodes must be used instead.

Within O45, choose O45.8 (Other premature separation of placenta) only when documentation doesn't support a more specific option: premature separation of placenta with coagulation defect (O45.0) and premature separation of placenta, unspecified (O45.9).

To report this condition, pick the subcode that matches the documentation: O45.8X (placenta).

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