About coding contraction ring dystocia
The ICD-10-CM code for contraction ring dystocia is O62.4 (Hypertonic, incoordinate, and prolonged uterine contractions).
Within O62 (abnormalities of forces of labor), O62.4 is specifically for Hypertonic, incoordinate, and prolonged uterine contractions. Related codes cover primary inadequate contractions (O62.0), secondary uterine inertia (O62.1), other uterine inertia (O62.2), precipitate labor (O62.3), other abnormalities of forces of labor (O62.8) and abnormality of forces of labor, unspecified (O62.9).
Don't report O62.4 together with the conditions in its Excludes1 note: dystocia (fetal) (maternal) NOS (O66.9).
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 O62.4)
- dystocia (fetal) (maternal) NOS (O66.9)
