About O43.8
O43.8 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 2 subcodes must be used instead.
Within O43, choose O43.8 (Other placental disorders) only when documentation doesn't support a more specific option: placental transfusion syndromes (O43.0), malformation of placenta (O43.1), Morbidly adherent placenta (O43.2) and unspecified placental disorder (O43.9).
To report this condition, pick the subcode that matches the documentation: O43.81 (infarction) and O43.89 (disorders).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
