Other abnormalities of forces of labor

This code represents various atypical patterns or dysfunctions of uterine contractions during labor that are not specifically classified elsewhere. It encompasses conditions where the strength, frequency, or coordination of contractions deviate from normal, impacting labor progression. These abnormalities can lead to prolonged labor or fetal distress.

Apply this code when documentation indicates uterine inertia, hypotonic or hypertonic uterine dysfunction, or uncoordinated uterine action not otherwise specified. This code is appropriate when the specific type of abnormal force of labor (e.g., prolonged latent phase, secondary arrest of dilation) is not documented or does not fit more specific codes. Supporting documentation should clearly describe the abnormal labor pattern observed.

• Do not use this code if a more specific code for a particular type of abnormal labor force (e.g., O62.0, O62.1, O62.2) can be assigned.
• Ensure the medical record clearly distinguishes between abnormal forces of labor and other labor complications, such as obstructed labor (O64-O66).
• Sequence this code as a secondary diagnosis when the primary reason for admission or intervention is related to the management of the abnormal labor.
