About O32

O32 is the ICD-10-CM diagnosis code for maternal care for malpresentation of fetus. 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 8 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: O32.0 (lie), O32.1 (presentation), O32.2 (lie), O32.3 (presentation), O32.4 (term), O32.6 (presentation), O32.8 (fetus) and O32.9 (unspecified).

Don't report O32 together with the conditions in its Excludes1 note: malpresentation of fetus with obstructed labor (O64.-).

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