About O64

O64 is the ICD-10-CM diagnosis code for obstructed labor due to malposition and malpresentation of fetus. It belongs to block O60-O77 (complications of labor and delivery) 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: O64.0 (head), O64.1 (presentation), O64.2 (presentation), O64.3 (presentation), O64.4 (presentation), O64.5 (presentation), O64.8 (malpresentation) and O64.9 (unspecified).

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