About coding labor irregular
The ICD-10-CM code for labor irregular is O62.2 (Other uterine inertia).
Within O62, choose O62.2 (Other uterine inertia) only when documentation doesn't support a more specific option: primary inadequate contractions (O62.0), secondary uterine inertia (O62.1), precipitate labor (O62.3), Hypertonic, incoordinate, and prolonged uterine contractions (O62.4), other abnormalities of forces of labor (O62.8) and abnormality of forces of labor, unspecified (O62.9).
Don't report O62.2 together with the conditions in its Excludes1 note: atony of uterus with hemorrhage (postpartum) (O72.1) and postpartum atony of uterus without hemorrhage (O75.89).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
Don't confuse with (Excludes1 for O62.2)
