About O65

O65 is the ICD-10-CM diagnosis code for obstructed labor due to maternal pelvic abnormality. 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: O65.0 (pelvis), O65.1 (pelvis), O65.2 (contraction), O65.3 (contraction), O65.4 (unspecified), O65.5 (organs), O65.8 (abnormalities) and O65.9 (unspecified).

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