About O44
O44 is the ICD-10-CM diagnosis code for placenta previa. It belongs to 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 6 subcodes must be used instead.
To report this condition, pick the subcode that matches the documentation: O44.0 (hemorrhage), O44.1 (hemorrhage), O44.2 (hemorrhage), O44.3 (hemorrhage), O44.4 (hemorrhage) and O44.5 (hemorrhage).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
