About O43.89

O43.89 is the ICD-10-CM diagnosis code for other placental disorders. It belongs to category O43 (placental disorders), 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 O43.8, choose O43.89 (Other placental disorders) only when documentation doesn't support a more specific option: placental infarction (O43.81).

To report this condition, pick the subcode that matches the documentation: O43.891 (first trimester), O43.892 (second trimester), O43.893 (third trimester) and O43.899 (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.
