About O46.8

O46.8 is the ICD-10-CM diagnosis code for other antepartum hemorrhage. It belongs to category O46 (antepartum hemorrhage, not elsewhere classified), 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 O46, choose O46.8 (Other antepartum hemorrhage) only when documentation doesn't support a more specific option: antepartum hemorrhage with coagulation defect (O46.0) and antepartum hemorrhage, unspecified (O46.9).

To report this condition, pick the subcode that matches the documentation: O46.8X (hemorrhage).

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